Description

TECHNICAL FIELD

[0001] The present application relates to acquisition of temperature of an electronic device and a control method for controlling an electronic device. BACKGROUND

[0002] In recent years, many imaging apparatuses capable of recording moving images are known. When an imaging apparatus records a moving image, heat is generated inside the imaging apparatus. Therefore, in order to reduce the influence on a user and protect the apparatus and image quality, countermeasures against the generated heat are important issues. In particular, due to the improvement in image quality of an image that can be captured in recent years, the increase in internal temperature of the apparatus in a state where a live view image is captured on standby greatly influences the shortening of recording time due to the increase in temperature when the apparatus records a moving image. Japanese Patent Application Publication No. 2008-311915 discusses a technology in which an operation of an electronic device is limited based on a measured temperature, and if the operation is limited, a state of operation recovery (such as indicating how many minutes are needed to recover the electronic device) is displayed so that a user can intuitively confirm how much time will elapse before the operation limitation is released. Japanese Patent Application Publication No. 2014-110506 discusses a technology in which, based on a measured temperature, a specific time indicates how long an operation of an electronic device needs to be turned off to allow the electronic device to continuously operate for a predetermined time or longer from a current time.

[0003] However, in Japanese Patent Application Publication No. 2008-311915 or Japanese Patent Application Publication No. 2014-110506, the time taken to release the limitation or the time during which the electronic device can be used is calculated using the environment or setting parameters at that time. Therefore, if the environment or the parameters change, the time needs to be calculated again. A user cannot easily recognize how much a change in an internal state such as a setting parameter influences the time taken to release the limitation, the time during which the electronic device can be used, or a change in temperature. SUMMARY

[0004] According to an aspect of the present application, an electronic device includes a display unit, and at least one memory and at least one processor functioning as a control unit configured to display a temperature change acquired from a temperature acquisition unit configured to acquire a temperature of the electronic device and a state change acquired from a detection unit configured to detect a state of the electronic device, wherein the control unit controls to display a single temperature change and a state change at a certain time point on the display unit.

[0019] A suitable example embodiment of the present application will be described below with reference to the accompanying drawings.

[0020] FIG. 1A and FIG. 1B shows an appearance view of a digital camera 100 as an example of an apparatus to which the present application is applicable. FIG. 1Ais a front perspective view of the digital camera 100. FIG. 1B is a rear perspective view of the digital camera 100. In FIG. 1A and FIG. 1B In the display unit 28 is a display unit provided on the back surface of the camera 100 and displays an image and various information. The touch panel 70a is an operation member capable of touch operation. The touch panel 70a is capable of detecting a touch operation on the display surface (operation surface) of the display unit 28. The viewfinder external display unit 43 is a display unit provided on the upper surface of the camera 100 and displays various setting values (such as setting values of shutter speed and aperture) of the camera 100.

[0021] The shutter button 61 is an operation unit for giving an image capturing instruction. In the still image capturing mode, the shutter button 61 is used to give a still image capturing preparation instruction or a still image capturing instruction. In the moving image capturing mode, the shutter button 61 is used to give an instruction to start or stop capturing (recording) of a moving image. The mode selection switch 60 is an operation unit for switching various modes. The terminal cover 40 is a cover for protecting a connection cable for connecting an external device and a connector (not shown) of the digital camera 100. The main electronic dial 71 is a rotary operation member included in the operation unit 70. The main electronic dial 71 is rotated so that a set value of a shutter speed or an aperture can be changed. The power switch 72 is an operation member for switching on and off of the digital camera 100. The sub electronic dial 73 is a rotary operation member included in the operation unit 70 and enables movement of a selection frame or image advance. The direction key 74 is an operation member included in the operation unit 70 and includes a button that can be pressed in four directions. The direction key 74 can be operated according to a direction in which the direction key 74 is pressed. The set button 75 is a button included in the operation unit 70 and is mainly used to confirm a selected item. The moving image button 77 is used to give an instruction to start or stop capturing (recording) of a moving image. If the shutter button 61 is pressed after the auto exposure (AE) lock button 78 is pressed, an image can be captured by fixing an auto focus (AF) position, or an image can be captured even in a case where AF cannot be performed. The reproduction button 79 is an operation button included in the operation unit 70 and is used to switch an image capturing mode and a reproduction mode. The reproduction button 79 is pressed in the image capturing mode so that the image capturing mode is changed to the reproduction mode, and a latest image among images recorded in the recording medium 200 can be displayed on the display unit 28. The assignment button 95 is a button included in the operation unit 70 and can be assigned other functions. In an initial state, the assignment button 95 functions as a button for displaying a status screen. The assignment button 95 can be assigned a function of changing a set content or a state related to capturing and reproduction of a moving image or a function of starting capturing (recording) of a moving image, as other functions. Alternatively, other assignment buttons than the assignment button 95 can be assigned a function of displaying a status screen.

[0022] The status screen is a screen including a plurality of pages, which displays a set content or a state related to capturing and reproduction of a moving image and an internal state of the digital camera 100.

[0023] The communication terminal 10 is a communication terminal for communication between the digital camera 100 and the lens unit 150 (which can be attached to and detached from the digital camera 100). The eyepiece section 16 is the eyepiece portion of the eyepiece viewfinder (internal viewfinder). The user can visually confirm the video displayed on the electronic viewfinder (EVF) 29, which is an internal viewfinder display unit, through the eyepiece section 16. The cover 202 is a cover for the slots housing the recording medium 200 and the battery. The grip section 90 is a holding part with a shape that makes it easy for the user to grip the grip section with their right hand when the user lifts the digital camera 100. The shutter button 61 and the main electronic dial 71 are positioned such that, while the user holds the digital camera 100 by gripping the grip section 90 with their right little finger, ring finger, and middle finger, the user can operate the shutter button 61 and the main electronic dial 71 with their right index finger. The secondary electronic dial 73 is positioned such that the user can operate it with their right thumb in the same state.

[0024] Air inlet 98 and exhaust outlet 99 are air passages used to cool the main body of the digital camera 100. If FIG. 2 When fan 92 rotates, air flows from intake 98 to exhaust 99, thereby releasing heat from the main body. The main body includes a temperature sensor 93. The temperature sensor 93 can measure the temperature of a specific part of the main body. Based on the measured temperature, fan 92 stops, or the rotation speed of fan 92 changes. Although described below, temperature status information based on the external and internal temperatures of the main body obtained from temperature sensor 93 is displayed on the screen. Multiple temperature sensors 93 or multiple fans 92 may be present.

[0025] FIG. 2 This is a block diagram illustrating an example construction of a digital camera 100 according to this exemplary embodiment. FIG. 2 In this context, lens unit 150 is a lens unit equipped with an interchangeable imaging lens. Although lens 103 typically comprises multiple lenses, FIG. 2 Only a single lens is shown in a simplified manner. Communication terminal 6 is used for communication between lens unit 150 and digital camera 100. Lens unit 150 communicates with system control unit 50 via communication terminals 6 and 10, and causes lens system control circuit 4 within lens unit 150 to control aperture 1 via aperture drive circuit 2. Then, lens unit 150 shifts lens 103 via AF drive circuit 3, thereby focusing lens 103.

[0026] Shutter 101 is a focal plane shutter that can freely control the exposure time of the camera unit 22 through the control of the system control unit 50.

[0027] The imaging unit 22 is an image sensor composed of a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) device, which converts an optical image into an electric signal. An analog-digital (A / D) converter 23 is used to convert an analog signal output from the imaging unit 22 into a digital signal.

[0028] The image processing unit 24 performs predetermined processing, such as resizing processing such as pixel interpolation and reduction and color conversion processing, on data from the A / D converter 23 or data from the memory control unit 15.

[0029] The image processing unit 24 performs predetermined calculation processing using captured image data. The system control unit 50 performs exposure control and distance measurement control based on a calculation result obtained by the image processing unit 24. Thus, AF processing, AE processing, and pre-flash (EF) processing are performed by a through-the-lens (TTL) method. Further, the image processing unit 24 performs predetermined calculation processing using captured image data, and performs automatic white balance (AWB) processing by a TTL method based on the obtained calculation result.

[0030] The memory control unit 15 controls data transmission and reception among the A / D converter 23, the image processing unit 24, and the memory 32. Output data from the A / D converter 23 is directly written into the memory 32 via the image processing unit 24 and the memory control unit 15 or via the memory control unit 15. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23 and image data to be displayed on the display unit 28 or the EVF 29. The memory 32 includes sufficient storage capacity for storing a predetermined number of still images and a predetermined time length of moving images and sound.

[0031] The memory 32 functions as an image display memory (video memory). Display-use image data written into the memory 32 is displayed on the display unit 28 or the EVF 29 via the memory control unit 15. The display unit 28 or the EVF 29 performs display on a display device such as a liquid crystal display (LCD) or an organic electroluminescence (EL) display in accordance with a signal from the memory control unit 15. Data is converted from analog data to digital data by the A / D converter 23, and the digital data is accumulated in the memory 32 and sequentially transferred to and displayed on the display unit 28 or the EVF 29, whereby the display unit 28 or the EVF 29 can perform live view display (LV display). Hereinafter, an image displayed in live view is referred to as a "live view image (LV image)".

[0032] The compression unit 26 compresses the time-sequentially stored image data in the memory 32 into Moving Picture Experts Group (MPEG) format data, thereby generating moving picture data. The generated moving picture data is stored in the memory 32 via the memory control unit 15, and then multiplexed with sound similarly stored in the memory 32. The resultant data is then written as a moving picture file to the recording medium 200.

[0033] The viewfinder external display unit 43 displays various setting values of the camera 100, such as setting values of shutter speed and aperture, via the viewfinder external display unit drive circuit 44.

[0034] The nonvolatile memory 56 is an electrically erasable recordable memory. For example, an Electrically Erasable Programmable Read Only Memory (EEPROM) is used as the nonvolatile memory 56. The nonvolatile memory 56 stores programs and constants for operation of the system control unit 50. The "program" used herein refers to a program for executing various flowcharts described below in the present exemplary embodiment.

[0035] The system control unit 50 is a control unit constituted by at least one processor and / or at least one circuit, and controls the entire digital camera 100. The system control unit 50 executes the above-described programs recorded in the nonvolatile memory 56, thereby realizing the processes described below in the present exemplary embodiment. A Random Access Memory (RAM) is used as the system memory 52, for example. Constants and variables for operation of the system control unit 50 and programs read from the nonvolatile memory 56 are loaded into the system memory 52. The system control unit 50 also controls the memory 32 and the display unit 28, thereby performing display control.

[0036] The system timer 53 is a time measuring unit that measures time for various types of control and time of a built-in clock.

[0037] The operation unit 70 including the mode selection switch 60, the first shutter switch 62, and the second shutter switch 64 is an operation unit for inputting various operation instructions to the system control unit 50.

[0038] The mode selection switch 60 is used to switch the operation mode of the system control unit 50 to any one of a still image recording mode, a moving image recording mode, and a reproduction mode. The still image recording mode includes an automatic shooting mode, an automatic scene recognition mode, a manual mode, an aperture priority mode (Av mode), a shutter speed priority mode (Tv mode), and a program AE mode. The still image recording mode also includes various scene modes in which shooting settings are made in accordance with a shooting scene and a custom mode. Using the mode selection switch 60, the user can directly switch to any one of these modes. Alternatively, using the mode selection switch 60, the user can switch to a list screen of shooting modes at a time, then select any one of a plurality of modes displayed on the list screen, and switch to the selected mode using other operation members. Similarly, the moving image recording mode can also include a plurality of modes.

[0039] The first shutter switch 62 is turned on in an intermediate state of the operation of the shutter button 61 provided in the digital camera 100, that is, by a so-called half-press (shooting preparation instruction), and generates a first shutter switch signal SW1. Based on the first shutter switch signal SW1, the system control unit 50 starts operations such as AF processing, AE processing, AWB processing, or EF processing.

[0040] The second shutter switch 64 is turned on by completion of the operation of the shutter button 61, that is, by a so-called full-press (shooting instruction), and generates a second shutter switch signal SW2. Based on the second shutter switch signal SW2, the system control unit 50 starts a series of shooting processing operations from reading of a signal from the imaging unit 22 to writing of image data to the recording medium 200.

[0041] The operation members of the operation unit 70 are appropriately assigned functions for respective scenes by performing operations of selecting various function icons displayed on the display unit 28, and function as various function buttons. The function buttons include, for example, an end button, a back button, a forward image button, a skip button, a zoom-out button, and a change attribute button. For example, if the menu button is pressed, a menu screen on which various settings can be made can be displayed on the display unit 28. The user can intuitively make various settings using the menu screen displayed on the display unit 28, the four-way button for up, down, left, and right directions, and the setting button 75.

[0042] The operation unit 70 is various operation members that serve as input units that receive operations from the user.

[0043] The operation unit 70 includes buttons, a rotary dial, and a touch sensor, and includes at least operation members such as the shutter button 61, the main electronic dial 71, the power switch 72, the sub electronic dial 73, the direction key 74, the setting button 75, the moving image button 77, the AE lock button 78, the reproduction button 79, and the assignment button 95.

[0044] The power supply control unit 80 includes a battery detection circuit, a direct current-direct current (DC / DC) converter, and a switching circuit for switching a block to which a current is to be applied. The power supply control unit 80 detects whether a battery is attached, the type of the battery, and the remaining amount of the battery. The power supply control unit 80 controls the DC / DC converter on the basis of the detection result and an instruction from the system control unit 50, and supplies a required voltage to components including the recording medium 200 for a required period of time. The power supply unit 30 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a nickel-cadmium (NiCd) battery, a nickel-metal hydride (NiMH) battery, or a lithium-ion (Li) battery, or an alternating current (AC) adapter.

[0045] The recording medium interface (I / F) 18 is an interface with the recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording captured image and moving image data, and is constituted by a semiconductor memory or a magnetic disk.

[0046] The communication unit 54 is connected to an external device wirelessly or via a cable for wired connection, and transmits / receives a video signal and a sound signal to / from the external device. The communication unit 54 can also be connected to a wireless local area network (LAN) or the Internet. The communication unit 54 can also communicate with the external device using Bluetooth Low Energy. The communication unit 54 can transmit an image (including an LV image) captured by the imaging unit 22 or an image stored in the recording medium 200 to the external device, and can also receive an image or various other information from the external device.

[0047] The orientation detection unit 55 detects the orientation of the digital camera 100 with respect to the direction of gravity. On the basis of the orientation detected by the orientation detection unit 55, the system control unit 50 can determine whether an image captured by the imaging unit 22 is an image captured with the digital camera 100 held horizontally or an image captured with the camera 100 held vertically. The system control unit 50 can add direction information according to the orientation detected by the orientation detection unit 55 to an image file of an image captured by the imaging unit 22, or store the image by rotating the image on the basis of the orientation detected by the orientation detection unit 55. An acceleration sensor or a gyro sensor can be used as the orientation detection unit 55. Using an acceleration sensor or a gyro sensor as the orientation detection unit 55, the system control unit 50 can also detect the motion of the digital camera 100 (whether the digital camera 100 is panned, tilted, lifted, or stationary).

[0048] The operation unit 70 includes a touch panel 70a as one of the operation members, which can detect a contact with the display unit 28. The touch panel 70a and the display unit 28 can be integrally formed. For example, the touch panel 70a is configured so that the light transmittance of the touch panel 70a does not hinder the display of the display unit 28. Then, the touch panel 70a is attached to the upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel 70a are associated with the display coordinates on the display screen of the display unit 28. Thus, it is possible to provide a graphical user interface (GUI) as if the user can directly operate the screen displayed on the display unit 28. The system control unit 50 can detect the following operations or the following states on the touch panel 70a.

[0049] • A state in which a finger or a pen that does not touch the touch panel 70a newly touches the touch panel 70a, that is, a touch start (hereinafter referred to as "touch-down").

[0050] • A state in which a finger or a pen touches the touch panel 70a (hereinafter referred to as "touch-on").

[0051] • A state in which a finger or a pen is moved while the finger or the pen keeps touching the touch panel 70a (hereinafter referred to as "touch move").

[0052] • A state in which a finger or a pen that touches the touch panel 70a is separated from the touch panel 70a, that is, a touch end (hereinafter referred to as "touch-up").

[0053] • A state in which there is no touch to the touch panel 70a (hereinafter referred to as "touch-off").

[0054] If the touch-down is detected, the touch-on is also detected at the same time. After the touch-down is detected, the touch-on is generally continuously detected unless the touch-up is detected. The touch move is also detected in the state in which the touch-on is detected. Even if the touch-on is detected, the touch move is not detected if the touch position is not moved. After the touch-up of all the fingers or the pens that touch the touch panel 70a is detected, the touch-off is detected.

[0055] These operations and states and the position coordinates of the finger or the pen touching the touch panel 70a are notified to the system control unit 50 via the internal bus. Based on the information that is notified to the system control unit 50, the system control unit 50 determines what touch operation is performed on the touch panel 70a.

[0056] In the case of touch movement, the system control unit 50 can also determine the moving direction of each of the vertical and horizontal components of the finger or pen moving on the touch panel 70a with respect to the touch panel 70a based on the change in the position coordinates. If it is detected that a touch movement of greater than or equal to a predetermined distance is performed, the system control unit 50 determines that a swipe operation is performed. An operation in which a finger is moved quickly by a certain distance while the finger is kept touching the touch panel 70a, and then the finger is separated from the touch panel 70a immediately after the quick movement is referred to as "flick". In other words, the flick is an operation in which the touch panel 70a is quickly traced in a flick manner with a finger. If it is detected that a touch movement of greater than or equal to a predetermined distance is performed at greater than or equal to a predetermined speed, and it is detected that the touch is lifted immediately after the touch movement, the system control unit 50 can determine that a flick is performed (it can be determined that a flick is performed after a swipe operation).

[0057] Further, a touch operation for simultaneously touching a plurality of positions (for example, two points) and bringing the touch positions close to each other is referred to as "pinch-in", and a touch operation for separating the touch positions from each other is referred to as "pinch-out".

[0058] The pinch-in and the pinch-out are collectively referred to as "pinch operation" (or simply "pinch").

[0059] The touch panel 70a can be a touch panel of various types such as a resistive type, a capacitive type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type, and an optical sensor type. Although depending on the type, a method of detecting the presence of a touch according to whether a finger or a pen is in contact with the touch panel 70a, or a method of detecting the presence of a touch according to whether a finger or a pen is close to the touch panel 70a, any one of them can be used.

[0060] The temperature sensors 93a to 93d are temperature sensors that measure the temperature of the surface and the inside of the housing of the digital camera 100, and are temperature acquisition units included in the temperature sensor 93. FIGS. 9A-9C An example of the temperature threshold (temperatures Kl and Kh) for limiting the operation of the digital camera 100 and the placement position of the temperature sensors 93a to 93d in each of the temperature sensors 93a to 93d is shown. FIG. 9Cis a view showing the digital camera 100 viewed from the display unit 28 side in a state where the EVF 29 faces upward. The temperature sensor 93a is a temperature sensor placed near the imaging unit 22, and measures the temperature near the device of the imaging unit 22. The temperature sensor 93b is a temperature sensor placed near the periphery of the connector protected by the terminal cover 40, and measures the temperature to calculate the temperature of the housing surface of the digital camera 100. The digital camera 100 avoids a situation where the housing surface reaches a certain high temperature (a temperature lower than the limit temperature for protecting the device, specifically, about 46°C), and a user causes a low-temperature burn while continuing to take an image with the grip 90 held at the temperature. The temperature sensor 93c is a temperature sensor placed near the display unit 28, and measures the temperature near the device of the display unit 28. The temperature sensor 93d is a temperature sensor placed inside the cover 202, and measures the temperature near the recording medium 200 or the battery. If each device reaches a high temperature (for example, 80°C or more), the device can not function normally, or the image quality can be degraded. Therefore, in order to prevent these phenomena, the temperature sensors 93a to 93d measure the temperature. In the present exemplary embodiment, four temperature sensors are placed near four devices. However, the number of sensors placed and the placement position of the sensors are not limited to this.

[0061] In FIGS. 3A-3C , the internal state of the digital camera 100 and the temperature change are displayed on the display unit 28, and when the temperature rises, the operation of the digital camera 100 is limited.

[0062] FIG. 3A is a control processing flowchart when the digital camera 100 is started (turned on) and is in the moving image recording mode in the imaging standby state. This control processing is implemented by the system control unit 50 loading a program stored in the nonvolatile memory 56 into the system memory 52 and executing the program. The recording time of this processing can be acquired from the frame number or the time code described in the management information attached to the moving image file, or can be acquired by analyzing the frame number of the moving image file.

[0063] In step S301, the system control unit 50 sets a variable n to n = 1, the variable n indicating the number of times of acquisition of the temperature acquired after the digital camera 100 is turned on and enters the imaging standby state. Then, the system control unit 50 saves the variable n in the system memory 52. If the digital camera 100 is turned off, or if the imaging mode processing (control processing for taking an image) is switched to other mode processing, the variable n is reset.

[0064] In step S302, the system control unit 50 acquires the temperature Kn of the camera 100 and the internal state at the clock time Xn. The internal state of the camera 100 is a state with respect to the shooting of an image, such as a camera standby state or a camera state (a state in which an image is being shot), or whether there is driving of a Wi-Fi function unit connected to the Internet via the communication unit 54 or driving of the fan 92.

[0065] In step S303, the system control unit 50 determines whether or not the temperature state display is enabled. If the temperature state display is enabled (YES in step S303), the processing proceeds to step S304. If the temperature state display is disabled (NO in step S303), the processing proceeds to step S305. The "temperature state display" refers to a display related to the temperature change of the digital camera 100. The user can arbitrarily set whether or not the temperature state display is performed. If the temperature state display is enabled, the display indicating the temperature change is performed on the display unit 28, and the user can confirm the details of the temperature change at the desired timing. Even if the temperature state display is disabled, the display with respect to the temperature is performed in a superimposed manner on the LV image. In this case, the amount of information is less than the details of the temperature change. However, the user can visually confirm the change in the temperature while confirming the LV image.

[0066] In step S304, the system control unit 50 performs the temperature state display on the display unit 28. This step will be described below with reference to the control flowchart in Fig. 12. FIG. 3B

[0067] In step S305, the system control unit 50 displays the temperature item as a simplified display of the temperature change together with the LV image on the display unit 28. FIG. 6C An example of the display performed on the display unit 28 at this time is shown.

[0068] In step S306, the system control unit 50 determines whether or not an instruction to shoot a moving image has been given. If the instruction has been given (YES in step S306), the processing proceeds to step S307. If the instruction has not been given (NO in step S306), the processing proceeds to step S308. Specifically, in the camera standby state, if the moving image button 77 is pressed, it is determined that the instruction has been given. In the state in which a moving image is being shot, if the moving image button 77 is pressed, a mode switching operation is performed, the reproduction button 79 is pressed, or the power switch 72 is operated, it is determined that the instruction has been given.

[0069] ​In step S307, the system control unit 50 starts or stops the recording of the moving image. If the moving image has not been recorded yet (the digital camera 100 is in the photographing standby state) by this step, the system control unit 50 starts the recording of the moving image, creates a moving image file in the recording medium 200, and records the moving image captured by the photographing unit 22 with the current setting contents. If the moving image has been recorded (the digital camera 100 has captured the moving image), the system control unit 50 stops the photographing of the image and performs closing processing (assignment of attribute information) on the moving image file created in the recording medium 200, according to the giving of the instruction.

[0070] In step S308, the system control unit 50 determines whether the predetermined time has elapsed. If the predetermined time has elapsed ("Yes" in step S308), the processing proceeds to step S311. Otherwise ("No" in step S308), the processing proceeds to step S309.

[0071] In step S309, the system control unit 50 determines whether Kn > Kl. If Kn > Kl ("Yes" in step S309), the processing proceeds to step S310. If Kn < Kl ("No" in step S309), the processing proceeds to step S312. If the internal temperature Kn of the digital camera 100 acquired in step S302 is higher than the predetermined temperature Kl, the internal temperature Kn can reach a predetermined temperature Kh (Kl < Kh) according to the temperature limiting operation. Therefore, the system control unit 50 performs control to lower the temperature Kn of the digital camera 100 (described below in FIG. 3C The temperatures Kl and Kh will be described below with reference to FIG. 4

[0072] In step S310, the system control unit 50 performs operation limiting processing for limiting the operation of the digital camera 100 according to the temperature. The operation limiting processing will be described below with reference to FIG. 3C

[0073] In step S311, the system control unit 50 sets the variable n to n + 1 and saves the variable n in the system memory 52. Then, the processing returns to step S302. In the present exemplary embodiment, since the determination is "Yes" in step S308 and the processing of step S311 is performed, the predetermined time interval for recording the device temperature and the device state is the same time. Alternatively, the predetermined time interval can be different according to the driving frequency of the temperature sensor 93 or the operation frequency of the system control unit 50.

[0074] ​​In step S312, the system control unit 50 determines whether the fan 92 is being driven due to the increase in the internal temperature Kn of the digital camera 100. If the fan 92 is being driven ("Yes" in step S312), the processing proceeds to step S313. Otherwise ("No" in step S312), the processing proceeds to step S314.

[0075] In step S313, the system control unit 50 stops the fan 92 that is being driven due to the increase in the internal temperature Kn of the digital camera 100. Since the determination was "No" in step S309 and "Yes" in step S312, it is understood that the fan 92 is being driven due to the internal temperature Kn of the digital camera 100 reaching a temperature higher than the predetermined temperature Kh that limits the operation. However, since the current temperature Kn of the digital camera 100 is less than or equal to Kl, the system control unit 50 determines that the internal temperature Kn of the digital camera 100 has sufficiently decreased. Then, the system control unit 50 stops the driving of the fan 92.

[0076] In step S314, the system control unit 50 determines whether the processing is ended. If the processing is ended ("Yes" in step S314), the FIGS. 3A-3C control flowchart ends. Otherwise ("No" in step S314), the processing returns to step S306.

[0077] The end of the processing refers to, for example, the turning off of the digital camera 100 or the transition to the processing of another mode other than the imaging mode processing.

[0078] FIG. 3B A control flowchart that starts when the determination is "Yes" (i.e., the temperature state display is enabled) in step S303 in FIG. 3A (step S304 in FIG. 3A is shown. In the flowchart shown in FIG. 3B , the display relating to the temperature change displayed on the display unit 28 is performed.

[0079] FIG. 4 and FIGS. 5A-5C A display example at this time is shown.

[0080] In step S321, the system control unit 50 plots the clock time Xn acquired in step S302 in FIG. 3A , the internal temperature Kn of the digital camera 100, and the internal state of the digital camera 100 on a graph and displays the graph on the display unit 28.

[0081] FIG. 4 A display example at this time is shown. The temperature that is acquired first in the case where the digital camera 100 is turned on and transitions to the imaging standby state is Kl. The clock time at which the temperature is acquired is Xl. FIG. 4The graph shown is for when n=11.

[0082] In step S322, the system control unit 50 determines whether variable n is greater than 1. If variable n is greater than 1 ("Yes" in step S322), the process proceeds to step S323. Otherwise ("No" in step S322), the process proceeds to step S324.

[0083] In step S323, the system control unit 50 connects the data Xn-1 and Kn-1 acquired when the variable n is n-1 with the data Xn and Kn acquired when the variable n is n using a line. Then, the system control unit 50 displays the resulting data as a line graph. At this time, the system control unit 50 also displays the internal state of the digital camera 100 as a graph.

[0084] In step S324, the system control unit 50 determines whether the fan 92 is being driven.

[0085] If fan 92 is being driven ("Yes" in step S324), then the process proceeds to step S325. Otherwise ("No" in step S324), FIG. 3B The control flow diagram in the document ends here.

[0086] In step S325, the system control unit 50 displays a display item about the drive of the fan 92 at the plotted point (on the plotted graph). FIG. 5A An example of the display at this time is shown.

[0087] In step S326, the system control unit 50 determines whether the speed of fan 92 has been selected. If the speed of fan 92 has been selected ("Yes" in step S326), the process proceeds to step S327. If the speed of fan 92 has not been selected ("No" in step S326), the process proceeds to step S328. Selecting the speed of fan 92, for example, means that the user selects the speed displayed on the display unit 28 along with the image. FIG. 5A The display item 520 displays setting item 520a via touch operation or by using the directional keys 74. If the user touches display item 520 or gives a command using the setting button 75, setting items 520a, 520b, and 520c are displayed. Setting items 520a to 520c are candidates for fan speed settings for fan 92. If the user touches setting item 520b or 520c or gives a command using the directional keys 74, the fan speed setting changes. FIG. 5A In the middle, the fan speed is set to low.

[0088] In step S327, the system control unit 50 highlights an icon corresponding to the speed of the currently selected fan 92. Specifically, in FIG. 5AIn this case, the system control unit 50 highlights the icon corresponding to the setting item 520a indicated by the indicator 522 (i.e., the icon at the time when the fan speed is set to low). The display form of the icon at this time is as shown in the display items 501 to 504.

[0089] In step S328, the system control unit 50 determines whether the user has touched the icon displayed together with the graph and indicating the fan speed. If the icon is touched (YES in step S328), the processing proceeds to step S329. If the icon is not touched (NO in step S328), the processing proceeds to step S330. FIG. 3B The control processing flowchart in FIG. 3A proceeds to step S306 in FIG. 5C Specifically, if a touch operation is performed on any one of the display icons 501 to 504 and the display icons 505 to 511 (if any one of the display icons 505 to 511 is selected), it is determined as YES, and the processing proceeds to step S329.

[0090] In step S329, the system control unit 50 displays information. Since it is determined as YES in step S328, the system control unit 50 displays information about the internal state of the digital still camera 100 at the time when the display item is selected by the user. Specifically, in accordance with the user touching the display item 511 in FIG. 5C , the system control unit 50 displays the display item 541 and the selection item 542 in an overlaid manner on the graph of the display unit 28.

[0091] In step S330, the system control unit 50 determines whether an instruction to change the setting is given. If the instruction is given (YES in step S330), the processing proceeds to step S331. If the instruction is not given (NO in step S330), the processing proceeds to step S332. FIG. 3B The control processing flowchart in FIG. 3A proceeds to step S306 in The system control unit 50 displays the selection item 542 together with the information displayed in step S329. If the user selects the selection item 542, the system control unit 50 can change the fan speed and the internal state of the digital still camera 100 all at once to the fan speed and the internal state at the clock time X11. Thus, while referring to the graph, the user can predict the future rise and fall of the temperature and change the setting.

[0092] In step S331, the system control unit 50 changes the fan speed and the internal state of the digital still camera 100.

[0093] FIG. 3C is the control flowchart when it is determined as YES (i.e., Kn > Kl) in step S309 in FIG. 3A .FIG. 3A In the flowchart shown in FIG. 10, when the temperature Kn of the digital camera 100 reaches a predetermined temperature or higher, the restriction operation is performed, and display is made on the display unit 28. FIG. 3C FIGS. 7A-7D FIG. 8A FIG. 8B FIG. 10 A display example at this time is shown in FIG. 12.

[0094] In step S341, the system control unit 50 determines whether the temperature Kn of the camera 100 acquired in step S302 of FIG. 9 is Kl < Kn < Kh. If Kl < Kn < Kh (YES in step S341), the processing proceeds to step S342. Otherwise (NO in step S341), the processing proceeds to step S347. Although described below with reference to FIG. 3A FIG. 4 Kl and Kh are temperature thresholds for restricting the operation of the digital camera 100 or changing the temperature display.

[0095] In step S342, the system control unit 50 determines whether a moving image is currently being recorded. If a moving image is being recorded (YES in step S342), the processing proceeds to step S343. Otherwise (NO in step S342), the processing proceeds to step S344.

[0096] In step S343, the system control unit 50 determines whether an instruction has been given by the user. If an instruction has been given (YES in step S343), the processing proceeds to step S344. Otherwise (NO in step S343), the processing proceeds to step S349. At this time, specifically, the instruction to cool the portion refers to an instruction to the assignment button 95.

[0097] In step S344, the system control unit 50 displays the portion to be cooled on the display unit 28. FIGS. 7A-7D FIG. 8A FIG. 8B A display example at this time is shown in FIG. 12.

[0098] In step S345, the system control unit 50 determines whether an instruction has been given by the user. If an instruction has been given (YES in step S345), the processing proceeds to step S346. Otherwise (NO in step S345), the processing proceeds to step S349. The user gives an instruction, whereby the system control unit 50 hides the portion to be cooled displayed in step S344 and returns the display to the display of the LV image or other imaging information desired by the user.

[0099] ​​​​​​​In step S346, the system control unit 50 hides the portion to be cooled that was displayed in step S344. Since the user gave the instruction in step S345, it can be assumed that the user is considering returning the display of the portion to be cooled to the LV image or other camera information that the user desires.

[0100] In step S347, similar to step S342, the system control unit 50 determines whether motion images are currently being recorded. If motion images are being recorded ("Yes" in step S347), the process proceeds to step S348. Otherwise ("No" in step S347), the process proceeds to step S349.

[0101] In step S348, the system control unit 50 stops recording the motion image and performs a closing process (attribute information allocation) on the motion image file created on the recording medium 200. Because in FIG. 3A In step S309, it is determined to be "yes" and FIG. 3C In step S341, it is determined to be "No", therefore it can be understood that the temperature Kn of camera 100 is Kn > Kh. Although the following references... FIG. 4 As described, Kh is a high temperature that makes various malfunctions highly likely in any of the temperature sensors 93a to 93d. Therefore, if the temperature Kn of the camera 100 becomes higher than Kh, the recording of moving images will stop even without a user-given instruction, thereby reducing the risk of image quality degradation or malfunction of components inside the digital camera 100.

[0102] In step S349, the system control unit 50 calculates a temperature difference between the temperature Tl measured by the temperature sensor 93 placed at a portion closest to the center portion of the digital camera 100 and the temperature T2 measured by the temperature sensor 93 placed at a portion closest to the outside of the digital camera 100. If the temperature difference T2-Tl is greater than a predetermined value (YES in step S349), the processing proceeds to step S352. If the temperature difference T2-Tl is less than or equal to the predetermined value (NO in step S349), the processing proceeds to step S350. If it is determined YES in step S349, it is understood that there is a large difference between the temperature of the outside (or the outside air) of the digital camera 100 and the temperature inside the digital camera 100. Therefore, the fan 92 is driven at the maximum speed without turning off the digital camera 100, thereby sucking the outside air into the digital camera 100. This can more effectively cool the inside of the digital camera 100. If it is determined YES in step S349, the fan 92 is driven at the maximum speed (described below in step S352), and the options regarding the following cooling methods are not displayed in step S350. This is because the temperature difference T2-Tl is greater than the predetermined value, and it is assumed that the fan 92 can more effectively and in a shorter time cool the digital camera 100 than turning off the digital camera 100. However, the present application is not limited to this. That is, even if the temperature difference T2-Tl is greater than the predetermined value, the options regarding the following cooling methods can be displayed in step S350. As the predetermined value, it is assumed to be a value of about 30°C to 40°C. However, the predetermined value depends on the size of the digital camera 100, and thus is not limited to this.

[0103] On the other hand, if it is determined NO in step S349, it is understood that the temperature difference between the outside and the inside of the digital camera 100 is not large. Therefore, compared to driving the fan 92, turning off the digital camera 100 and reducing the heat generated due to the continuous on of the digital camera 100 can more effectively cool the digital camera 100. In the present exemplary embodiment, the temperature T2 is a temperature measured by the temperature sensor 93b or 93d (or both the temperature sensors 93b and 93d) which is considered to be able to measure the outside (outside air) temperature, and the temperature Tl is a temperature measured by the temperature sensor 93a.

[0104] In step S350, the system control unit 50 displays the options on the display unit 28. FIG. 10A display example at this time is shown. Since the determination in step S349 is "No", the temperature difference T2-T1 is less than or equal to the predetermined value. Therefore, there is no great difference in the degree of temperature Kn of the digital camera 100 dropping, whether the cooling by driving the fan 92 (described below in step S352) or the cooling by turning off the digital camera 100 is selected. However, if the digital camera 100 is still in the video recording standby state after the recording of the moving image is stopped, the temperature Kn of the digital camera 100 drops so slowly that the recording of the next moving image cannot be started. Therefore, as shown in the option, the option is displayed on the display unit 28, and the user is allowed to select either option. FIG. 10

[0105] In step S351, the system control unit 50 determines which option the user has selected. If the fan rotation is selected, the process proceeds to step S352. If the digital camera 100 is turned off, the process proceeds to step S353.

[0106] In step S352, the system control unit 50 starts the driving of the fan 92 in a state where the rotation speed of the fan 92 is the maximum speed, and the process returns to step S309 in FIG. 3A The driving of the fan 92 driven in this step is continued until the temperature Kn of the digital camera 100 is less than or equal to the predetermined threshold value (Kn < Kl). By such control, the internal temperature Kn of the digital camera 100 can be sufficiently dropped. Even if the user restarts the recording of the moving image, the temperature Kn of the digital camera 100 does not immediately reach the temperature Kh of the limit operation. Therefore, the moving image can be recorded for a longer time.

[0107] In step S353, the system control unit 50 turns off the digital camera 100. Then, FIG. 3C the control flowchart in FIG. 34 ends, and FIG. 3A the control flowchart in FIG. 35 also ends.

[0108] FIG. 4 A display example 1 of a graph displayed as the temperature state on the display unit 28 is shown. The graph indicates the temperature Kn and the internal state of the digital camera 100 at the clock time. The horizontal axis indicates the time (Xn), and the vertical axis indicates the temperature (Kn). The time when the digital camera 100 is turned on is X0. That is, every time the user turns off the digital camera 100, the graph is reset. As described with reference to FIG. 3A ​The variable n is increased in accordance with the passage of a predetermined time or a change in the internal state of the digital camera 100 as described in the control flowchart. The broken line 404 indicates the temperature Kh. The broken line 406 indicates the temperature Kl. The temperatures Kh and Kl are temperature thresholds for preventing malfunction of the devices included in the digital camera 100, preventing a decrease in the image quality of the captured moving image, or ensuring the safety of the user of the digital camera 100. From FIG. 4 As can be seen from the graph in FIG. 10, the temperatures Kh and Kl have a relationship of Kh > Kl. Two levels of thresholds are provided, thereby identifying the rise and fall of the temperature Kn of the digital camera 100 in a stepwise manner and notifying the user of the rise and fall. The temperatures Kl and Kh are standard temperatures for avoiding reaching the actual operation limit temperature. Each of the temperatures Kl and Kh can be a temperature at which the devices actually malfunction or the image quality of the moving image actually decreases, can be a lower temperature, or can have a range. The broken line 406 can also be displayed as a band having a predetermined width.

[0109] The temperatures K1 to K4 at the clock times X1 to X4 are lower than Kl (Kn < Kl). From the clock time X1 to the clock time X3, the internal state of the digital camera 100 is the recording standby state. At the clock time X3, if the recording of the moving image is started, the internal state of the digital camera 100 changes to the state of recording the moving image. At the clock time X4, the internal state of the digital camera 100 is the state of recording the moving image. The internal state of the digital camera 100 is displayed below the graph of the temperature state display (in the area 410). Specifically, the internal state can be viewed by performing the band-like display as shown in the state display 402. In the moving image recording standby state, "STBY" is displayed. In the state of recording the moving image, "REC" is displayed. From the clock time X1 to the clock time X4, the recording of the moving image is started at the clock time X3, and the internal state of the digital camera 100 is the recording state from the clock time X3 (REC is displayed in the graph). Due to the driving of the imaging unit 22 and the image processing unit 24 caused by the start of the recording of the moving image at the clock time X3, the power consumption of these devices increases and the degree of change (rate of change) of the internal temperature Kn of the digital camera 100 increases.

[0110] The temperatures K5 to K8 at the clock times X5 to X8 are greater than or equal to Kl and less than or equal to Kh (Kl ≤ Kn ≤ Kh).

[0111] The internal state of the digital camera 100 is the state of recording the moving image ("REC"). At the clock time X6, Wi-Fi is turned on by the user. Therefore, "Wi-fi On" is displayed below the graph as shown in the state display 403 in FIG. 11. FIG. 4 The internal state of the digital camera 100 is the state of recording the moving image ("REC"). At the clock time X6, Wi-Fi is turned on by the user. Therefore, "Wi-fi On" is displayed below the graph as shown in the state display 403 in FIG. 11.

[0112] The temperatures K9 and K10 at the clock times X9 and X10 are temperatures higher than Kh (Kn > Kh).

[0113] According to the fact that the temperature Kn reaches a temperature higher than Kh, i.e., at the clock time X9, if the moving image is being recorded, the recording of the moving image is stopped, and the digital camera 100 transitions to the recording standby state. Therefore, as shown in FIG. 4 the display of the internal state of the digital camera 100 also changes. In FIG. 4 the state in which the moving image is being recorded, the temperature Kn reaches a temperature higher than Kh, so the recording of the moving image is stopped, and the operation of the digital camera 100 is restricted, thereby causing the digital camera 100 to enter the standby state. However, the present application is not limited to this. If the temperature Kn becomes higher than Kh in the recording standby state, the Wi-Fi or the digital camera 100 is turned off, or the fan 92 is started to be driven. At the clock time X10, the temperature K10 continues to be higher than the temperature Kh from the clock time X9. Therefore, the fan 92 is driven. The Wi-Fi is also turned off. The band display of the state display 403 is hidden. Therefore, it can be understood that the Wi-Fi is turned off. If the state in which the temperature Kn is higher than the temperature Kh continues for a long time, the device of the digital camera 100 is likely to be affected and malfunction. Therefore, in addition to the control for stopping the recording of the moving image at the clock time X9, the fan 92 is driven, thereby lowering the temperature Kn of the digital camera 100. The state of driving the fan 92 at this time is indicated by the state display 405 ("FAN"). Since the state display 405 is not displayed until the clock time X10, the fan 92 is not driven until the clock time X10. As described above, since Kh is the temperature at which the operation is started to be restricted to prevent the malfunction of the digital camera 100, the operation of the digital camera 100 is restricted according to the fact that the temperature Kn becomes higher than the threshold value Kh even if there is no user operation.

[0114] The temperature K11 at the clock time X11 is greater than or equal to K1 and less than or equal to Kh (K1 ≤ Kn ≤ Kh). It can be understood that the temperature K11 reaches less than or equal to Kh by driving the fan 92 at the clock time X10. As described above, the user can visually confirm the temperature Kn and the internal state of the digital camera 100. Therefore, the operation is restricted or the fan 92 is driven, so that the user is able to predict to what extent the temperature Kn of the digital camera 100 will be lowered, so that the digital camera 100 is able to resume the recording of the moving image.

[0115] Another device state that affects the device temperature can be recorded. For example, a video recording setting state such as a recording format (e.g., a file format or a codec), a recording resolution, or a frame rate can be recorded. A display unit lighting state of a display unit included in the display unit 28 or the viewfinder external display unit 43, or a lighting brightness state indicating a brightness when the display unit is lit can be recorded. A communication state of an external input / output terminal included in the recording medium I / F 18 can be recorded. An attachment state of an external device such as a lens (e.g., the lens unit 150), a tripod, various terminals, a grip, a flash, an illumination lamp, a stand, a mudguard, a filter, or a housing, or an insertion / removal state of a recording medium such as the recording medium 200 can be recorded. A power saving mode state in which power consumption is different, or a high performance mode state in which performance is improved by making the power consumption higher than normal can be recorded. A cooling mode state in which the digital camera 100 operates by preferentially cooling the device temperature rather than normal operation can be recorded. A state of a sensor driving mode that is different in terms of an update cycle of a sensor (e.g., the imaging unit 22 or the A / D converter 23) or a method of reading a signal of a pixel can be recorded. A power supply state of a battery included in the power supply unit 30, an AC power supply, or a universal serial bus (USB) power supply can be recorded. A surrounding environment state estimated by using the temperature sensor 93 or acquiring a weather or an air temperature of a current location via external communication through the communication unit 54, or a surrounding environment state estimated from a stop value of the lens unit 150, a shutter speed of the shutter 101, a sensitivity of the imaging unit 22, or an exposure value Ev obtained from an imaging result can be recorded.

[0116] As described above, from the temperature state display (graph) shown in FIG. 9, the user can understand that the slope of the line graph gradually becomes larger upward from the clock time X3, and becomes larger upward from the clock time X6. From the slope of the graph and the information about the internal state of the digital camera 100, the user can understand that the recording of the moving image is started at the clock time X3, and the Wi-Fi is turned on at the clock time X6. That is, the user can visually confirm that the internal temperature Kn of the digital camera 100 greatly rises by starting the wireless communication using the Wi-Fi. Although the rising rate is small compared to the case where the wireless communication is started using the Wi-Fi, the user can understand that the internal temperature Kn also rises by starting the recording of the moving image. FIG. 4

[0117] On the contrary, the slope of the graph changes downward from the clock time X9, and becomes larger downward from the clock time X10. Based on these changes, the internal temperature Kn can be lowered by stopping the recording of the moving image. The lowering of the temperature Kn can be further promoted by driving the fan 92.

[0118] As described above, from the temperature state display (graph) shown in FIG. 9, the user can understand that the slope of the line graph gradually becomes larger upward from the clock time X3, and becomes larger upward from the clock time X6. From the slope of the graph and the information about the internal state of the digital camera 100, the user can understand that the recording of the moving image is started at the clock time X3, and the Wi-Fi is turned on at the clock time X6. That is, the user can visually confirm that the internal temperature Kn of the digital camera 100 greatly rises by starting the wireless communication using the Wi-Fi. Although the rising rate is small compared to the case where the wireless communication is started using the Wi-Fi, the user can understand that the internal temperature Kn also rises by starting the recording of the moving image. FIG. 4 ​The temperature state display is shown, whereby the user can visually confirm the state in which the temperature rises in the case of a change in the internal state of the digital camera 100. Furthermore, not only a change in the recording state of the moving image but also a change in the communication state of the wired or wireless communication and the driving state (cooling state) of the fan 92 are displayed together with the temperature state display. Therefore, the user can visually confirm which function contributes to the rise and fall of the internal temperature of the digital camera 100 and the degree of contribution of the function. Even in the case where the temperature exceeds the predetermined threshold value and the digital camera 100 becomes unable to record the moving image, the user can understand which function should be changed to which state to more effectively cool the digital camera 100. The user can predict how long the digital camera 100 should be cooled so that the digital camera 100 can resume the recording of the moving image. Therefore, it is possible to more effectively record the moving image without wasting time.

[0119] That is, based on the display example 1 of the temperature state display according to the present exemplary embodiment, the internal temperature and the internal state of the digital camera 100 at each clock time are recorded and displayed, whereby the user can visually confirm the internal state that causes the temperature change. Furthermore, the user can predict and imagine what countermeasures should be taken to prevent the temperature rise or effectively lower the temperature when the temperature rises. That is, it is possible to assist the user in selecting the countermeasure to control the temperature.

[0120] As the internal state of the digital camera 100 displayed together with the temperature state display, the recording state of the moving image, the communication state, and the driving state (cooling state) of the fan 92 have been described. However, the present application is not limited to these. For example, the following states can also be displayed: a state of external connection with an external display device (high-definition multimedia interface ) through wired or wireless communication; and a power saving state (for example, a setting content of automatic power off) as a state related to the power consumption of the digital camera 100. The following states can also be displayed: a recording medium state as a state of the specification (communication speed or capacity) of the recording medium 200; and a display state regarding whether to display the LV image as a high-quality image of 4K or 8K on the display unit 28. The driving state of the imaging unit 22 related to the presence or absence of the driving of the imaging unit 22 (that is, the presence or absence of image capturing using the imaging unit 22) can also be displayed together with the temperature state display similarly performed on the display unit 28.

[0121] FIGS. 5A-5C A display example 2 of the temperature state display (graph) performed on the display unit 28 is shown. In the graph, the vertical axis, the horizontal axis, the clock times X1 to X11, the temperatures K1 to K11, and the internal states S1 to S11 are the same as in FIG. 4 FIGS. 5A-5C ​In this case, a situation where the fan 92 is driven during the entire period from the clock time Xl to the clock time Xl l is considered. FIG. 5A The display in steps S325 and S327 in FIG. 3B The display in step S329 of FIG. 5C The display in step S329 of FIG. 3B

[0122] In the display item 500 of FIG. 5A In the display item 500 of FIG. 4 In the display item 500 of FIG. 5A The display item 520 shown in FIG. 27 indicates options that can be set and the current setting relating to the speed setting of the fan 92, and is displayed in accordance with the user's selection (e.g., in the touch). In a state where the user has not selected the display item 520 (in FIG. 5C ), the setting items 520b and 520c as options for the speed setting of the fan 92 and the indicator 522 are not displayed. That is, in a case where the user selects (performs the touch in) the setting item 520a, the setting items 520b and 520c are displayed. In accordance with the fact that the user selects any one of the setting items 520a to 520c, the indicator 522 is displayed for the selected setting item, and the speed setting of the fan 92 is changed. If the indicator 522 is moved to the setting item 520b ("medium") by the user's instruction, the display items 505 to 509 are highlighted. Similarly, if the indicator 522 is moved to the setting item 520c ("high"), the display items 510 and 511 are highlighted. If the user performs the determination process on the fan speed where the cursor is displayed (performs the touch operation again or presses the setting button 75 at the display position of the cursor), the user can change or determine the fan speed. With this display, the user can visually confirm to what extent the internal temperature Kn of the digital camera 100 will change if the speed of the fan 92 is changed. The fan speed can be changed without opening the setting menu screen. This can save the trouble.

[0123] FIG. 5B The display item 530 in FIG. 27 is a table that shows the temperature state display in FIG. 5A ​The information in the plot data in the display item 500 shown in FIG. 12 is related to the setting of the temperature Kn or the fan speed. The display item 530 is updated and loaded into the memory 32 each time the temperature Kn or the setting of the fan speed is acquired. The "temperature" in the display item 530 is information acquired from the temperature sensor 93, and the "fan" described in the display item 530 is information acquired from the setting state of the fan 92 stored in the nonvolatile memory 56. If the user changes the setting state of the fan 92 on the setting menu screen, the setting state of the fan 92 is loaded into the nonvolatile memory 56, and the setting is maintained when the digital camera 100 is next activated. The display items 501 to 504 indicate that the speed of the fan 92 is set to low. The display items 505 to 509 indicate that the speed of the fan 92 is set to medium. The display items 510 and 511 indicate that the speed of the fan 92 is set to high. The "clock time" in the display item 530 indicates the clock time when the internal temperature Kn of the digital camera 100 or the speed setting of the fan 92 is acquired via the temperature sensor 93.

[0124] In the present exemplary embodiment, the display item 530 is taken as an example in which the number of plot data displayed in the display item 500 is 10, and the information is updated every 10 minutes. However, the present application is not limited to this. Although the plot data is plotted on the display item 500 every 10 minutes, the interval for the plot data is not limited to 10 minutes. The plot data can be plotted not only based on time, but also in the case where the temperature Kn reaches the temperature Kl, is higher than Kl or lower than Kl, or reaches the temperature Kh, is higher than Kh or lower than Kh, or in the case where the internal state of the digital camera 100 changes.

[0125] If the user selects the setting item 520a (if the indicator 522 is displayed for the setting item 520a), the display items 501 to 504 indicating the corresponding fan speed are highlighted. In the present exemplary embodiment, the display items are highlighted so that the user is easily able to visually confirm the display items. If the user changes the speed setting of the fan 92 to medium (the setting item 520b), the display items 505 to 509 are highlighted. Similarly, if the user changes the speed setting of the fan 92 to high (the setting item 520c), the display items 510 and 511 are highlighted.

[0126] FIG. 5CAn example of the display on the display unit 28 in the case where the user selects any one of the display items 501 to 511 displayed in the display item 500 is shown. According to the fact that the display item 511 is selected by the user (in the touch), the display item 541 is displayed in a superimposed manner on the display item 500. The display item 541 indicates the setting content of the speed of the fan 92 and the internal state of the digital camera 100 at the clock time X11 indicated by the display item 511 selected by the user. If the selection item 542 is selected, the setting content and the internal state can be collectively changed to the state indicated by the display item 541.

[0127] In the present exemplary embodiment, the speed setting of the fan 92 can be set to high, medium, and low. Alternatively, a setting (for example, automatic) for automatically changing the speed setting of the fan 92 according to the internal temperature Kn of the digital camera 100 can be included.

[0128] In the present exemplary embodiment, the relationship between the temperature and the time is displayed as a line graph. However, the present application is not limited to this. Alternatively, as in the display item 540, if a touch on any indicator or the outer peripheral area of the display items 501 to 511 is detected on the touch panel 70a included in the operation unit 70, detailed information can be displayed, and the fan setting can be directly changed to the fan setting at the touch point. For example, if the fan speed setting state 511 is touched in the display item 540, the fan setting can be displayed as shown in the display item 541, and if the selection item 542 is touched, the setting can be changed. If the selection item 542 is pressed in the display item 540, the fan speed displayed at the lower right of the screen of the display item 540 is changed from "low" to "high". By this direct setting through the touch, the appropriate setting can be confirmed and the setting can also be easily reflected. The display item 541 is not limited to the pop-up display as shown. The display item 541 can be displayed above the display item 520, that is, below the graph. FIG. 5C

[0129] As described with reference to FIGS. 5A-5C , the temperature state display as shown in Display Example 2 is performed, whereby the user can visually confirm the presence or absence of the driving of the fan 92 at each clock time in the graph, not only the internal state of the fan 92 and the internal state of the digital camera 100. Even if the user does not store the setting parameters at each clock time, the user can recognize the setting content at each clock time, and also recognize the influence of the setting parameters and the internal state of the digital camera 100 on the change in the internal temperature at each clock time. Further, the user can change the setting parameters while referring to the graph. Thereby, the user can make the change to more effectively change (lower) the internal temperature of the digital camera 100 without feeling cumbersome.​

[0130] FIGS. 6A-6C Display example 3, showing a temperature status display on display unit 28, is shown. As display example 3... FIGS. 6A-6C Display items indicating the current temperature and the degree of temperature change are shown. These display items are displayed on the LV image displayed on the display unit 28 in an overlay manner to show the temperature status.

[0131] FIG. 6A An example display showing the current temperature and the degree of temperature change of the digital camera 100 is shown.

[0132] Based on the above references FIG. 4 The described temperatures K1 and Kh (K1 < Kh) are used to determine whether the current temperature is lower or higher than K1 and Kh. The current temperature is then displayed as a temperature icon. For example, if the temperature Kn measured in step S302 is Kn < Kl, the display is as shown in display item 601. If Kl ≤ Kn < Kh, the display is as shown in display item 602. If Kn ≥ Kh, the display is as shown in display item 603. That is, in display item 601, the temperature sensor icon is displayed in white. As the temperature increases, the color of the temperature sensor icon changes. In display item 602, the temperature sensor icon is displayed in light red. In display item 603, the temperature sensor icon is displayed in red. Therefore, based on the change in the display format of the display item (temperature sensor icon), the user can visually confirm whether the temperature is rising or falling. In particular, regarding the rise in temperature, the state where the temperature approaches the temperature affecting the drive of the digital camera 100 is indicated in red, thereby indicating a warning to the user.

[0133] The degree of temperature change is indicated by display items 604 to 608, which serve as temperature change icons. If the temperature rises rapidly, display item 604 is displayed on display unit 28. If the temperature rises slowly, display item 605 is displayed on display unit 28. If the temperature change is small or the temperature does not change, display item 606 is displayed. If the temperature drops slowly, display item 607 is displayed. If the temperature drops rapidly, display item 608 is displayed.

[0134] FIG. 6B An example of temperature information displayed overlaid on an LV image is shown. The temperature information includes a temperature icon determined based on the temperature Kn at clock time Xn (any of display items 601 to 603) and a temperature change icon determined based on the temperatures at clock times Xn-2, Xn-1, and Xn (display items 604 to 608). If clock times Xn-2 and Xn-1 are not available, only the temperature change icon at clock time Xn is displayed.

[0135] Display items 611 and 612 show an example of a case where the temperature Kn of the digital camera 100 is rising. The display item 611 includes the display item 601 indicating the temperature at the current time and the display items 606, 605, and 606 indicating the degree of change in temperature. According to the display item 601, the user can understand that the temperature Kn of the digital camera 100 at the current time is Kn < Kl, and is a sufficiently low temperature with respect to the temperature that affects malfunction of the camera 100. According to the display items 606, 605, and 606, the user can understand that the temperature Kn of the digital camera 100 is rising, but the degree of change (rate of change) is not very large. Therefore, the user can understand that even if the processing being performed in the current state of the digital camera 100 continues, the temperature Kn is unlikely to reach the temperature Kh at which operation is limited in a short time.

[0136] The display item 612 includes the display item 601 indicating the temperature at the current time and the display items 604, 605, and 604 indicating the degree of change in temperature. According to the display item 601, the user can understand that the temperature Kn of the digital camera 100 at the current time is Kn < Kl, and is a sufficiently low temperature with respect to the temperature that affects malfunction of the camera 100. According to the display items 604, 605, and 604, the user can understand that the temperature Kn of the digital camera 100 at the current time is a low temperature, but if the processing being performed in the current state of the digital camera 100 continues, the temperature Kn is likely to reach the temperature Kh at which operation is limited in a short time.

[0137] The display items 613 and 614 show an example of a case where the user is cooling the overheated device. The display item 613 includes the display item 603 indicating the temperature at the current time and the display items 607, 608, and 607 indicating the degree of rise (drop) in temperature. According to the display item 603, the user can understand that the temperature Kn of the digital camera 100 at the current time is Kn > Kh, and has reached the temperature that affects malfunction of the camera 100 or is a high temperature reaching that temperature. According to the display items 607, 608, and 607, the user can understand that the temperature Kn of the digital camera 100 is dropping, and the degree of drop (rate of cooling) is also large. Therefore, the user can imagine that if cooling continues by maintaining the current state of the digital camera 100, the temperature Kn of the digital camera 100 reaches a low temperature in a short time, and the digital camera 100 can resume recording of moving images.

[0138] The display items 614 include a display item 603 indicating the temperature of the current time and display items 606, 607, and 606 indicating the degree of temperature rise (drop). According to the display item 603, the user can understand that the temperature Kn of the digital camera 100 at the current time is Kn > Kh, and that the temperature of the failure affecting the camera 100 is reached or a high temperature reaching the temperature is reached. According to the display items 606, 607, and 606, the user can understand that the temperature Kn of the digital camera 100 tends to drop, but the degree of drop (cooling rate) is not large. Therefore, the user can imagine that even if the cooling continues by maintaining the current state of the digital camera 100, it takes time for the temperature Kn of the digital camera 100 to reach a sufficiently low temperature at which the recording of the moving image can be resumed.

[0139] FIG. 6C The reference image 620 is displayed on the LV image in a superimposed manner. FIG. 6A and FIG. 6B An example of the temperature information described is shown. The display item 622 is displayed on the LV image 621 displayed on the display unit 28 in a superimposed manner. In either of the state in which the moving image is being recorded and the standby state, the user can confirm the LV image and can also confirm the temperature information on the digital camera 100. Therefore, the user can determine whether to continue the recording of the moving image or to suspend the recording of the moving image and cool the digital camera 100. If the digital camera 100 is to be cooled, the user can consider whether to further increase the cooling rate with respect to the current set state. The user can visually confirm the degree of change in the temperature with time, and thus can also adjust the schedule or plan of the moving image recording thereafter.

[0140] In the present exemplary embodiment, the temperature is displayed as an icon. Alternatively, the temperature can be displayed as a gauge display of the current temperature with respect to the upper limit temperature. Yet another alternative is to notify the user of the information by changing the light emission color of a signal lamp included in the display unit 28. Not only by using an arrow as a temperature change icon, but also by switching the flashing interval of a signal lamp included in the display unit 28, the user can be notified of the change in the temperature. In the present exemplary embodiment, the temperature difference per unit time is calculated. Alternatively, the time interval at which the temperature difference is calculated can be changed. The number of temperature change icons placed at this time can be three as in the present exemplary embodiment, or can be increased or decreased.

[0141] In the present exemplary embodiment, the LV image 621 and the temperature information are displayed on the display unit 28. Alternatively, the LV image 621 and the temperature information can be displayed on the viewfinder external display unit 43 or the EVF 29. Yet another alternative is that the user can be informed of the temperature information by changing the flicker color or flicker interval of a signal lamp included in the display unit 28. When a terminal such as a personal computer (PC) or a smartphone is connected to the system control unit 50 via the communication unit 54, the temperature information can be transmitted to the terminal, and the user can be informed of the temperature information. In the present exemplary embodiment, both the temperature icon and the temperature change icon are informed to the user as the temperature information. Alternatively, only the temperature change icon can be informed to the user.

[0143] As in the display control described with reference to 3A and FIG. 3B and FIGS. 4-6C In the display control described with reference to 3A and

[0144] In the display example 3 of the temperature state display described with reference to FIG. 3A and FIG. 3B In the display example 3 of the temperature state display described with reference to FIGS. 4-6C The temperature state display described with reference to

[0145] FIGS. 7A-7D and FIG. 8A and FIG. 8B Examples of the display on the display unit 28 in the case where the user gives an instruction (presses the assignment button 95 in the present exemplary embodiment) in the moving image recording standby state or in the state where the moving image is being recorded are shown. These are in the case where the temperature state display is performed in the moving image recording standby state or in the state where the moving image is being recorded.​FIG. 3C Examples of the display performed in step S344. FIGS. 7A-7D An example of the display is shown. FIG. 8A and FIG. 8B An example of the display is shown. FIGS. 9A-9C The temperature threshold of the temperature sensor 93 and the placement position of the temperature sensor 93 are shown.

[0146] Based on the temperatures of the plurality of portions acquired from the temperature sensor 93, the portion closest to the temperature Kh at which the operation is restricted is notified to the user. The digital camera 100 explicitly indicates which portion of the digital camera 100 should be cooled (cooling recommended portion), so that the digital camera 100 can record a moving image for a longer period of time without restricting the operation.

[0147] FIG. 7A Examples of displaying the housing of the digital camera 100 are shown, thereby notifying the user of the cooling recommended portion indicating which portions should be cooled. Images 701 and 702 show the external view of the digital camera 100.

[0148] The regions 703 to 707 indicate the placement positions of the temperature sensors 93 placed inside the digital camera 100. The regions to be displayed correspond to the number of the temperature sensors 93 placed. A plurality of temperature sensors can be associated with a single region, or a plurality of regions can be displayed for a single temperature sensor. The temperature displayed in each region is determined in such a manner that the system control unit 50 detects the temperature measured by the temperature sensor 93 at every certain period or the temperature measured by the temperature sensor 93 when the assignment button 95 is pressed.

[0149] The display items 708 to 711 indicate the cooling recommended portion. The display item 708 indicates the portion for cooling the position of the region 703. The display item 709 indicates the portion for cooling the position of the region 705. The display item 710 indicates the portion for cooling the position of the region 706. The display item 711 indicates the portion for cooling the position of the region 707. The cooling recommended portion only needs to be able to indicate which position in the digital camera 100 the cooling recommended portion exists in. Therefore, the cooling recommended portion is not limited to the display shown as FIG. 7A and can be indicated using a representation in which the region indicating the position flashes.

[0150] In a case where the system control unit 50 compares the temperature measured by the temperature sensor 93 corresponding to the position in the digital camera 100 and the threshold value corresponding to the position and the temperature exceeds the threshold value, the cooling recommendation section is displayed. In a case where there are a plurality of threshold values, if the temperature exceeds any one or more of the plurality of threshold values, the cooling recommendation section is displayed. At this time, the system control unit 50 can use a fixed value such as a value stored in the system memory 52, or can use a dynamic value such as a value calculated from the state of the digital camera 100 using a calculation formula, as the threshold value for displaying the cooling recommendation section.

[0151] The area 712 indicates the air intake port 98 of the fan 92, and the area 713 indicates the air exhaust port 99 of the fan 92. The display items 714 and 715 indicate the position of the fan 92. At this time, the display item 714 is displayed so that the user can visually confirm that the display item 714 indicates the air intake port 98, and the display item 715 is displayed so that the user can visually confirm that the display item 715 indicates the air exhaust port 99. The areas 712 and 713 and the display items 714 and 715 indicating the position of the fan 92 are displays that are particularly effective in lowering the internal temperature Kn of the digital camera 100. If the fan 92 is being used, the vicinity of the air intake port 98 of the fan 92 is cooled, and thus the cooled air can be sent into the digital camera 100. Therefore, the inside of the digital camera 100 can be more effectively cooled. On the other hand, even if the vicinity of the air exhaust port 99 of the fan 92 is cooled, air is only exhausted from the air exhaust port 99. Therefore, the inside of the digital camera 100 cannot be effectively cooled using the fan 92. That is, the areas 712 and 713 and the display items 714 and 715 are displayed in a superimposed manner on the images 701 and 702 that are the appearance of the digital camera 100, and thus the user can more effectively use the fan 92 to cool the inside of the digital camera 100.

[0152] As FIG. 7B indicated, the degree of change in the temperature measured by the plurality of temperature sensors 93 can be displayed as a bar graph together with the appearance of the digital camera 100. Specifically, together with the cooling recommendation section described with reference to FIG. 7A the position in the digital camera 100 corresponding to the areas 703 to 707 (the placement position of the temperature sensor 93) and the difference between the threshold value corresponding to each position and the measured temperature are displayed on the display unit 28.

[0153] By reducing FIG. 7AThe graph 723 is a bar graph indicating the difference between the threshold value for limiting operation and the temperature measured by the temperature sensor 93 for each placement position of the temperature sensor 93 placed in the digital camera 100. The display item 724 on the X axis indicates the position in the digital camera 100 corresponding to the temperature sensor 93. The display items 718 to 720 on the Y axis indicate the temperature threshold values corresponding to each position in the digital camera 100. The display item 718 on the Y axis indicates the temperature that is sufficiently low to use the digital camera 100. The display item 719 on the Y axis indicates the temperature close to the temperature threshold value for limiting operation. The display item 720 on the Y axis indicates the temperature that is the temperature at which the digital camera 100 is forced to be turned off to prevent the digital camera 100 from malfunctioning (temperature at which operation is limited). Not all of the threshold values corresponding to each position need to be displayed. For example, only the display item 720 on the Y axis indicating the temperature at which the digital camera 100 is forced to be turned off, or only the element on the Y axis indicating the threshold value for displaying the cooling recommendation section determined by the system control unit 50 can be displayed.

[0154] The display item 724 on the X axis indicates the position in the digital camera 100 corresponding to the temperature sensor 93.

[0155] The bars 725, 716, and 717 indicate the latest measurement, the latest previous measurement, and the latest previous two measurements, respectively, among the temperatures measured by the temperature sensor 93 at each position. Alternatively, only the latest measurement can be displayed. Any number of past measurements can be displayed. The measurements are obtained by the system control unit 50 selecting from the memory 32 the temperature measured by the temperature sensor 93 at each position every certain period or when the assignment button 95 is pressed. The system control unit 50 can use a fixed value stored in the system memory 52, or can use a value set by the user, as the certain period. When displaying the measurements, the system control unit 50 can compare the temperature measured by the corresponding temperature sensor 93 with the corresponding threshold value stored in the system memory 52 for each position in the digital camera 100, and change the color of the bar graph according to the comparison result.

[0156] The display items 718 to 720 on the Y axis indicate the temperature threshold values corresponding to each position in the digital camera 100. The display item 718 on the Y axis indicates the temperature that is sufficiently low to use the digital camera 100. The display item 719 on the Y axis indicates the temperature close to the temperature threshold value for limiting operation. The display item 720 on the Y axis indicates the temperature that is the temperature at which the digital camera 100 is forced to be turned off to prevent the digital camera 100 from malfunctioning (temperature at which operation is limited). Not all of the threshold values corresponding to each position need to be displayed. For example, only the display item 720 on the Y axis indicating the temperature at which the digital camera 100 is forced to be turned off, or only the element on the Y axis indicating the threshold value for displaying the cooling recommendation section determined by the system control unit 50 can be displayed.

[0157] The area 721 includes the display item 724, a graph corresponding to each temperature sensor 93 in the display item 724, and an outer periphery of the graph. When the inside of the area 721 displayed on the display unit 28 is touched, the system control unit 50 can perform display so that the area 707 indicating the position in the digital camera 100 corresponding to the display item 724 on the X axis flashes in the images 701 and 702. If the inside of the area 721 is touched by the user, the position of the display item 724 on the X axis corresponding to the area 721 is determined, and the area in the images 701 and 702 corresponding to the touched element is highlighted.

[0158] FIG. 7C and FIG. 7D An example in which the recommended cooling method is displayed in addition to the appearance of the digital camera 100 in FIG. 7A is shown.

[0159] The message 732 is a message notifying the user of a more effective cooling method in the case where the area 731 is cooled. The message 734 is a message notifying the user of a more effective cooling method in the case where the area 733 is cooled. As the messages 732 and 734, the message to be displayed changes depending on which of the temperatures measured by the temperature sensors 93a to 93d exceeds the threshold value. Specifically, as shown in FIG. 9A , the area to be displayed on the display unit 28 changes depending on which of the temperature sensors 93a to 93d enters which temperature state (temperature states 1 to 3). Then, the corresponding message shown in FIG. 9B is displayed. The message 732 or 734 can be displayed in accordance with selection of the area display of the area 731 or 733 by user operation, or can be displayed only for the portion for which the temperature acquired by the temperature sensor 93 exceeds the temperature threshold value for limiting operation. If the temperatures measured by a plurality of temperature sensors exceed the threshold value, a plurality of messages can be displayed. Not only the message but also the area display can flash or can be highlighted.

[0160] Referring to FIGS. 7A-7DThe images 701 and 702 described may be an external view of the digital camera 100 or a schematic diagram simulating the digital camera 100. Any number of images 701 or 702 can be displayed depending on the location or number of cooling recommendation sections to be displayed. In this exemplary embodiment, the transmittance is set to a level that allows the user to visually confirm the display of the LV image. The cooling recommendation section is then displayed overlaid on the LV image. This means that the cooling recommendation section is temporarily displayed, and the user can easily confirm the LV image if desired. Even when the cooling recommendation section is displayed, the display of information regarding the motion picture recording status (“STBY” or “REC”) and the motion picture recording time is important information about the recording of the motion picture; therefore, the user is allowed to visually confirm the information display without user intervention. Thus, the user can visually confirm the minimum information about the recording of the motion picture, and also confirm other information about the cooling recommendation section.

[0161] Multiple thresholds are determined for a single area display. Alternatively, the number of thresholds may be one. Thresholds are determined for each area display. The system control unit 50 acquires a threshold corresponding to the area display for comparison and compares the threshold with the temperature measured by the temperature sensor 93 corresponding to the area display. Based on the comparison result, the system control unit 50 displays or hides the area display, or changes the color of the area display or the type of icon attached to the area display. FIG. 9A An example of the relationship between the display of each region and the threshold is shown. The "Position in Camera" column indicates the display of each region. The "Temperature State 1," "Temperature State 2," and "Temperature State 3" columns each indicate the temperature state inside the display of each region, categorized by the threshold for each region's display. FIG. 9A In this context, each region displays two threshold values. Therefore, as a comparison between the threshold values ​​and the temperature, each region displays three temperature states. As described above, FIG. 9A and FIG. 9B The temperature sensors 93a to 93d shown are temperature sensors installed at different locations inside the digital camera 100, and measure the temperature at those locations within the camera 100. FIG. 9AAs shown in "Lens surface" and "Grip", when measuring the temperature of a single location in the camera 100, a plurality of temperature sensors can be used to measure the temperature. Then, a threshold value can be provided for each temperature sensor, and a temperature state can be determined. On the other hand, as in "LCD", "Medium", and "Battery", a single temperature sensor can also be used to determine the temperature state. Based on the relationship between the placement position of the temperature sensor 93 and the cooling recommendation section, it is determined whether to use a single temperature sensor or a plurality of temperature sensors for determination. As in "Lens surface" and "Grip", even at different locations, the same temperature sensor can be used to determine the temperature state. Further, as in "Medium" and "Battery", even at different locations, the same temperature sensor and the same threshold value can be used to determine the temperature state. In the present exemplary embodiment, "LCD" refers to the display unit 28. That is, the message 732 indicates that the display unit 28 is recommended to be cooled by applying a coolant to the display unit 28. Similarly, FIG. 9A and FIG. 9B "LCD" shown in "LCD", "Medium", and "Battery" also refers to the display unit 28.

[0162] The system control unit 50 can use a fixed value such as a value stored in the system memory 52, or can use a dynamic value such as a value calculated from the state of the digital camera 100, as the individual threshold values displayed for the individual regions. When FIG. 9A the threshold value when the temperature state 1 transitions to FIG. 9A the temperature state 2 shown in "LCD" and the threshold value when the temperature state 2 transitions to the temperature state 1 can be set to different threshold values according to the states before and after the transition, as the individual threshold values displayed for the individual regions. This is because if these threshold values have the same value, the temperature state can change between the temperature states 1 and 2 in a short time, and the temperature state can change instantaneously. Therefore, the user can feel inconvenienced, or can become confused.

[0163] FIG. 8A An example is shown in which the cooling recommendation section indicating which sections should be cooled is notified to the user by text. As described above with reference to FIGS. 7A-7D the cooling recommendation section is the placement position of the temperature sensor 93.

[0164] In a case where the temperature measured by any of the temperature sensors 93 exceeds the temperature Kh that limits the operation of the digital camera 100 (described above with reference to FIG. 4(As described), message 816 is displayed on display unit 28. If a temperature sensor 93 measures a temperature exceeding temperature Kh, the location where the temperature sensor 93 is placed is displayed as a high-temperature region. If the temperature Kn obtained by the temperature sensor 93 is Kl≤Kn≤Kh, the location where the temperature sensor 93 is placed is displayed as a medium-temperature region. If there are multiple thresholds corresponding to each location, the temperature status can be set and displayed for each threshold based on the temperature measured at each location and the number of thresholds exceeded, such as... FIG. 9A As shown.

[0165] FIG. 8B Message 817 is a message displayed on the display unit 28 when the temperature Kn is less than Kl in all the temperature sensors 93 placed in the digital camera 100. If Kn is less than Kl in all the temperature sensors 93, the message may not be displayed. FIG. 7A The appearance and reference of the digital camera 100 shown FIG. 8B The message described is 817.

[0166] FIG. 10 It shows in FIG. 3B In step S350, an example of the cooling method options for cooling the digital camera 100 is displayed on the display unit 28. Dialog box 1001 is displayed overlaid on the LV image. In dialog box 1001, selection items 1002 and 1003 and message 1004 are displayed.

[0167] Message 1004 displays the text "Fan rotation is effective when cooling the camera." Although text as in message 1004 is shown in this exemplary embodiment, the invention is not limited thereto.

[0168] For example, the text "There are two ways to cool the camera" can be displayed.

[0169] If the user selects option 1002, the fan 92 will start running. If the user selects option 1003, the digital camera 100 will be turned off.

[0170] If the remaining charge of the battery included in the power supply unit 30 is less than a predetermined amount, the digital camera 100 is turned off, regardless of the user's selection or the temperature difference T2-T1. That is, in FIG. 3BThe remaining amount of the battery is determined before the determination in step S349. Then, if the remaining amount of the battery is less than a predetermined amount, the processing proceeds to step S353. If the fan 92 is driven in a state where the remaining amount of the battery is less than the predetermined amount, electric power is used for the fan 92. As a result, the remaining amount of the battery becomes 0, and the moving image cannot be recorded. Therefore, if the remaining amount of the battery is less than the predetermined amount, the digital camera 100 is turned off, thereby cooling the digital camera 100. If the digital camera 100 is sufficiently cooled by this processing, the digital camera 100 is turned on again and the recording of the moving image can be resumed. By this control, the recording of the moving image, which is considered to be the first priority of the user, can be performed without the user feeling inconvenienced.

[0171] As described above, according to the present exemplary embodiment, the optimum cooling method is determined according to the situation between different cooling methods (for example, cooling by rotating the fan and cooling by turning off the electronic device) and the optimum cooling method is executed, thereby being able to more efficiently cool the electronic device.

[0172] FIG. 11A and FIG. 11B The case where the temperature state display is enabled is shown in the flowchart shown in FIG. 17. FIG. 3A The flowchart shown in FIG. 18 is started if it is determined as "Yes" (that is, the temperature state display is enabled) in step S303 in FIG. 17. FIG. 3A In the flowchart shown in FIG. 18, the display regarding the change in the temperature displayed on the display unit 28 is performed. FIG. 11A and FIG. 11B In the flowchart shown in FIG. 18, the display regarding the change in the temperature displayed on the display unit 28 is performed.

[0173] FIGS. 12A-12C An example of the display performed in the flowchart shown in FIG. 18 is shown. FIG. 11A Examples of the display in the case where the time interval of the graph to be drawn can be changed (FIGS. 19 and 20) and the case where the digital camera 100 is turned off for a specific short time (FIG. 21) are shown. FIGS. 12A-12C The data regarding the temperature information stored inside the digital camera 100 at this time is shown. FIG. 12A FIG. 12B FIG. 12C An example of the display performed in the flowchart shown in FIG. 18 is shown. FIG. 12D The data regarding the temperature information stored inside the digital camera 100 is shown. Referring to FIG. 22, a description is given of the control in the case where the digital camera 100 is turned off for a specific long time.

[0174] FIG. 13A An example of the display performed in the flowchart shown in FIG. 18 is shown. FIG. 11B The data regarding the temperature information stored inside the digital camera 100 is shown. Referring to FIG. 22, a description is given of the control in the case where the digital camera 100 is turned off for a specific long time. FIG. 13B FIG. 11B First, a description is given of the case where the temperature state display is not enabled.

[0175] First, a description is given of the case where the temperature state display is not enabled. FIG. 11A ​​​the control flowchart in FIG. 11. In step S1101, the system control unit 50 draws grid lines of the graph and displays the graph on the display unit 28. At this time, the grid lines are drawn based on the information about the time interval of the graph stored in the nonvolatile memory 56.

[0176] In step S1102, similarly to step S301, the system control unit 50 sets a variable n indicating the number of times of acquisition of temperature to n = 1. Then, the system control unit 50 saves the variable n in the system memory 52.

[0177] In step S1103, the system control unit 50 stores the latest data identification (ID) as TempID in the nonvolatile memory 56. The "data ID" refers to the ID displayed in the item 1231 of FIG. 10 and assigned to the acquired data. For the latest data ID, the data indicating "true (TRUE)" is set in the item "Latest data?" displayed in the item 1234 of FIG. 10. If new data is further added after the data ID "55", the item 1234 of the data ID "55" is set to "false (FALSE)", and the item 1234 of the new data ID "56" is set to "true". FIG. 12D FIG. 12D

[0178] In step S1104, the system control unit 50 acquires temperature information corresponding to TempID and calculates the Y-position of the graph from the temperature information. The system control unit 50 draws a point at the position (Xn, Y) with respect to the X-coordinate and Y-coordinate using the calculated Y-position.

[0179] In step S1105, the system control unit 50 sets PrevTempID = TempID - 1. The PrevTempID indicates a TempID one ID older than the latest TempID.

[0180] In step S1106, the system control unit 50 determines whether there is temperature information corresponding to n < 16 and PrevTempID. If it is determined "yes" (YES in step S1106), the processing proceeds to step S1107. If it is determined NO (NO in step S1106), the processing proceeds to step S1108. FIG. 11A In step S1106, the system control unit 50 determines whether there is temperature information corresponding to n < 16 and PrevTempID. If it is determined "yes" (YES in step S1106), the processing proceeds to step S1107. If it is determined NO (NO in step S1106), the processing proceeds to step S1108.

[0181] ​​In step S1107, the system control unit 50 calculates t seconds as the difference between the date and time of PrevTempID and the date and time of TempID, and stores the t seconds in the nonvolatile memory 56.

[0182] In step S1108, the system control unit 50 determines whether t calculated in step S1107 is less than or equal to 1 minute and 30 seconds. If t is less than or equal to 1 minute and 30 seconds ("Yes" in step S1108), the processing proceeds to step S1109. If t is greater than 1 minute and 30 seconds ("No" in step S1108), the processing proceeds to step S1112. The determination of the time t in this step depends on the frequency of acquisition of data on the temperature acquired from the temperature sensor 93. In the present exemplary embodiment, the frequency of acquisition of data is set so that data is acquired approximately every minute. Details of the frequency of acquisition of data will be described below with reference to FIG. 12D Although control is performed so that data is acquired approximately every minute, depending on the processing order of the tasks of the temperature sensor 93 or the system control unit 50, the acquisition timing can exceed 1 minute. Therefore, the acquisition timing has a range of 30 seconds. If data cannot be acquired for longer than 1 minute and 30 seconds, it is determined that the digital still camera 100 is turned off. That is, if the digital still camera 100 is turned on immediately after being turned off, the next data can be acquired within 1 minute and 30 seconds. Therefore, the temperature map (temperature state) is not drawn, and the digital still camera 100 is turned off.

[0183] In step S1109, the system control unit 50 acquires the temperature information corresponding to PrevTempID, and calculates the Y position from the temperature information. The system control unit 50 draws a point at the position (Xn+1, Prev_Y) with respect to the X-coordinate and Y-coordinate using the calculated Y position.

[0184] In step S1110, the system control unit 50 draws a line by connecting the point drawn at the position (Xn+1, Prev_Y) in step S1109 and the point drawn at the position (Xn, Y) in step S1104.

[0185] In step S1111, the system control unit 50 sets n = n + 1 and TempID = PrevTempID, and stores n and TempID in the nonvolatile memory 56.

[0186] In step S1112, since the determination is "No" in step S1108, the system control unit 50 sets the variable m to m = n + t / 60, and stores the variable m in the nonvolatile memory 56.

[0187] In step S1113, the system control unit 50 determines whether m ≤ 16. If m ≤ 16 (yes in step S1113), the process proceeds to step S1114. If not (no in step S1113), then... FIG. 11A The control flow diagram in the document ends here.

[0188] In step S1114, the system control unit 50 acquires the temperature information corresponding to PrevTempID and calculates the Y-position based on the temperature information. The system control unit 50 then uses the calculated Y-position to draw a point at the location (Xm, Prev_Y) with respect to the X-coordinate and Y-coordinate.

[0189] In step S1115, the system control unit 50 sets n = m and TempID = PrevTempID and stores n and TempID in non-volatile memory 56.

[0190] In step S1116, the system control unit 50 determines whether an instruction to change the time interval of the graph to be displayed has been given. If an instruction has been given ("Yes" in step S1116), the process proceeds to step S1117. If no instruction has been given ("No" in step S1116), the process returns to step S1105. Specifically, the instruction to change the time interval refers to... FIG. 12A The instructions in the display item are 1203 or 1204.

[0191] In step S1117, the system control unit 50 draws grid lines by changing the time interval.

[0192] Next, the description FIG. 11B The control flow diagram in [the document / document]. (And / or...) FIG. 11A Control steps similar to those in the control steps are obtained through... FIG. 11A The control steps are represented by the same step numbers, therefore they will not be described further. See reference... FIG. 11A The situation where the digital camera 100 is turned off for a short period of time has already been described, such as... FIG. 12C As shown. In, as FIG. 12C As shown, with a time interval of 1 minute (time 1202), and if the digital camera 100 is turned off for approximately 2 minutes, only a portion of the graph is not plotted. However, with a time interval of 1 minute, and if the digital camera 100 is turned off for a longer period such as 15 minutes, most of the graph may not be plotted, and displaying the temperature graph may be meaningless. Therefore, in cases where the digital camera 100 has been turned off for a predetermined time or longer, instead of simply plotting the exact time the digital camera 100 was turned off on the graph, it is displayed in an abbreviated manner.

[0193] In step S1121, similarly to step S1109, the system control unit 50 acquires the temperature information corresponding to PrevTempID, and calculates the Y-position from the temperature information. The system control unit 50 plots a point using the calculated Y-position at the position (Xn+1, Prev_Y) with respect to the X- and Y-coordinates.

[0194] In step S1122, similarly to step S1108, the system control unit 50 determines whether t calculated in step S1107 is less than or equal to 1 minute and 30 seconds. If t is less than or equal to 1 minute and 30 seconds (YES in step S1122), the process proceeds to step S1123. If t is greater than 1 minute and 30 seconds (NO in step S1122), the process proceeds to step S1124.

[0195] In step S1123, similarly to step S1110, the system control unit 50 plots a line by connecting the point plotted at the position (Xn+1, Prev_Y) in step S1121 and the point plotted at the position (Xn, Y) in step S1104.

[0196] In step S1124, the system control unit 50 displays an indicator indicating that the digital still camera 100 is turned off on the graph together with the time at which the digital still camera 100 is turned off. FIG. 13A An example of the display at this time is shown.

[0197] In step S1125, similarly to step S1111, the system control unit 50 sets n = n + 1 and TempID = PrevTempID, and stores n and TempID in the nonvolatile memory 56.

[0198] FIGS. 12A-12D An example of the display and a table of data IDs in the case where the control flowchart in FIG. 11A is executed is shown. FIG. 11A An example of the display and a table of data IDs in the case where the control flowchart in FIG. 11A is executed is shown. FIG. 13A and FIG. 13B An example of the display and a table of data IDs in the case where the control flowchart in FIG. 11A is executed is shown. FIG. 11B

[0199] A graph obtained by plotting and connecting 16 points (16 times and 16 pieces of temperature information acquired) is shown. In the graph 1200, the horizontal axis represents time, and the vertical axis represents temperature information. The vertical grid lines are plotted at equal intervals. FIGS. 12A-12C

[0200] An example of the display and a table of data IDs in the case where the control flowchart in FIG. 11A is executed is shown. FIG. 12A FIG. 11A ​The temperature graph displayed when "Yes" is determined in step S1108. Point 1201 indicates the latest temperature information and is displayed in a different format than other points (in this case, a double circle). Since each grid line indicates 1 minute, it can be understood that point 1205 is 5 minutes before point 1201, which indicates the latest temperature information. Since 16 points are acquired, the user can visually confirm the change in temperature information at point 1208, which indicates the temperature information 15 minutes before the latest temperature information (point 1201).

[0201] The display indicates that point 1205 is 5 minutes prior to the latest point 1201 (time 1206). If the user gives instructions for displaying item 1203 or 1204... FIG. 11A In step S1116), time 1202 changes, and the time width (interval) indicated by the grid lines in Figure 1200 changes. As the time interval changes, time 1202 also changes. If in FIG. 12A If an instruction is given to display item 1204 in the state shown, then Figure 1200 will change to have... FIG. 12B The temperature graph shown illustrates the time intervals. Even in... FIG. 12A In this state, giving instructions to display item 1203 will not change the time interval.

[0202] FIG. 12B A temperature graph with 3-minute time intervals is shown. FIG. 11A If "yes" is determined in step S1108, the display will show the item. If an instruction is given to display item 1203, the time interval will change to 1 minute (Figure 1200 changes to...). FIG. 12A If a command is given to display item 1204, the time interval changes to 5 minutes. Point 1215 indicates the temperature information 15 minutes prior to point 1201, which indicates the latest temperature information. Since the time interval is 3 minutes, the user can visually confirm the change in temperature information at point 1218, which indicates the temperature information 45 minutes prior to the latest temperature information (point 1201). FIG. 12B The time interval in the middle is greater than FIG. 12A The time intervals in the graph result in a relatively flat curve. Other items and references FIG. 12A The items described in the temperature graph are similar.

[0203] FIG. 12C It shows a time interval of 1 minute and in FIG. 11AThe temperature graph is displayed if step S1108 is determined to be "No". Points 1225 and 1226 are plotted with the lines on the graph broken (no connecting lines). This indicates that between points 1225 and 1226, the digital camera 100 is turned off and no time and temperature information is acquired. FIG. 12D This shows a table indicating the data ID, temperature, date, and time, and the data obtained for plotting the temperature graph. FIG. 12C In the diagram, when the digital camera 100 is off, the lines are not connected. However, the invention is not limited to this. Alternatively, for example, the lines can be connected, and the color of the lines can be changed only during the period when the digital camera 100 is off, or the lines can be drawn as dashed lines. Yet another alternative, only the corresponding portions can be masked to indicate the state where the digital camera 100 is off.

[0204] exist FIG. 12D In this system, temperature sensor 93 acquires the temperature every minute and stores the temperature information along with date and time information in non-volatile memory 56. The data acquired for the temperature graph is stored corresponding to 300 minutes. Even when the time interval is changed, the acquisition frequency of the data acquired by temperature sensor 93 remains unchanged. That is, data is acquired every minute even when the time interval is changed. FIG. 12D There is a difference of approximately 3 minutes between the date and time of data ID 49 and data ID 50. This is because data is acquired approximately once per minute by temperature sensor 93, and based on... FIG. 11A The determination in step S1108 can be understood as ensuring that no data can be acquired for 1 minute and 30 seconds or longer. Therefore, based on this data, it is assumed that the digital camera 100 is turned off. Then, no points are plotted on the temperature map. The following will refer to... FIG. 11B The flowchart and FIG. 13A and FIG. 13B Describes the control of temperature status display when data cannot be acquired for an extended period of time.

[0205] This control allows the user to identify the extent to which the temperature Kn of the digital camera 100 will drop due to its off state. Therefore, even if the temperature Kn of the digital camera 100 rises when the next image is captured, the user can predict how long the digital camera 100 should be turned off to allow its temperature Kn to drop to a level where the user can capture the image within the desired timeframe. Furthermore, since the user cannot capture the image within the desired timeframe due to the temperature rise when the next image is captured, the loss of image capture opportunities can be reduced.

[0206] FIG. 13A A temperature graph with 1-minute time intervals is shown. FIG. 11Bis displayed in the case where the determination in step S1106 of FIG. 11 is "No". Dot 1301 indicates the latest temperature information. Dot 1305 indicates a point about 5 minutes before the latest temperature information. Dot 1306 indicates a point about 30 minutes before dot 1305. Dots 1305 and 1306 are plotted in the case where the line of the graph is broken (no connecting line) and the omitted display 1312 and time 1311 are plotted. This indicates that between dots 1305 and 1306, the digital camera 100 was turned off and no time and temperature information was acquired. FIG. 13B A data table indicating the data ID, temperature, and date and time at this time and data acquired for plotting the temperature graph is shown.

[0207] In FIG. 13B , the temperature sensor 93 acquires the temperature every minute and stores the temperature information together with the date and time information in the nonvolatile memory 56, similarly to the data table shown in FIG. 12D

[0208] In FIG. 13B , there is a difference of about 30 minutes between the date and time of the data ID 49 and the date and time of the data ID 50. Since the temperature sensor 93 acquires data about every minute and, based on the determination in step S1122 of FIG. 11, it is understood that the situation where data cannot be acquired for 1 minute and 30 seconds or more. Therefore, based on these data, it is assumed that the digital camera 100 was turned off. Then, no dot is plotted on the temperature graph. However, at this time, if the dots are simply not connected together in the state where the digital camera 100 is turned off, this results in a state where no dot is plotted at all on the graph 1300. Therefore, the user is likely to be confused. It is likely that the digital camera 100 was turned off for about 30 minutes. Therefore, if data is not plotted on the graph every time, this is not user-friendly. Therefore, if the time difference t between a plurality of data on the temperature stored in the nonvolatile memory 56 exceeds 1 minute and 30 seconds (the "No" in step S1122 of FIG. 11), the dots are not connected together by a line and further an omitted display is made. Although in FIG. 11B FIG. 11A FIGS. 12A-12D FIG. 11B FIG. 13A ​​​​​The display shown in the omitted display 1312 is performed in the middle, but the present application is not limited to this. At this time, the digital camera 100 is also instructed how long to be turned off (time 1311). With this control, the user can recognize how long the digital camera 100 should be turned off to lower the temperature Kn of the digital camera 100 and to what extent the temperature Kn of the digital camera 100 will be lowered. Therefore, even if the temperature Kn of the digital camera 100 rises at the time of capturing the next image, the user can predict how long the digital camera 100 should be turned off to lower the temperature Kn of the digital camera 100 to a temperature at which the user can capture an image within a desired time. Further, since the user cannot capture an image within a desired time due to the temperature rise at the time of capturing the next image, it is possible to reduce the loss of image capturing opportunities.

[0209] In the present exemplary embodiment, the time interval can be changed to any one of 1 minute, 3 minutes, 5 minutes, and 10 minutes. In the present exemplary embodiment, as described above, the time interval of the temperature graph that can be changed by the user is determined in advance. Alternatively, the user can be allowed to optionally and freely set the time interval.

[0210] In the above description, in the state where the digital camera 100 is turned off, the points are not connected together by a line in the graph. However, the present application is not limited to this. For example, even in the still image mode, since the temperature of the digital camera 100 is unlikely to rise, it is not necessary to care about the internal temperature, and the temperature state display can be controlled similarly to the state where the digital camera 100 is turned off.

[0211] The above-described various controls performed by the system control unit 50 in the description can be executed by a single hardware, or the processing of the above-described various controls can be shared by a plurality of hardware (for example, a plurality of processors or circuits), so that the control device as a whole.

[0212] Although the present application has been described in detail based on appropriate exemplary embodiments thereof, the present application is not limited to these specific exemplary embodiments. The present application also includes various forms without departing from the spirit and scope of the present application. Further, the above-described exemplary embodiments merely show exemplary embodiments of the present application, and can also be appropriately combined together.

That is, the present application is applicable to a personal computer, a personal digital assistant (PDA), a mobile telephone terminal, a mobile image viewer, a printer device including a display, a digital photo frame, a music player, a game device, or an electronic book reader.

[0214] The present application is not only applicable to an electronic device main body, but also applicable to a control device that communicates with an electronic device including a digital camera and a network camera and remotely controls the electronic device through wired or wireless communication. Examples of the device that remotely controls the electronic device include a device such as a smartphone, a tablet PC, and a desktop PC. Based on an operation performed in the control device or a process performed in the control device, the control device notifies the electronic device of a command to perform various operations and make various settings, so that the electronic device can be remotely controlled. The control device can receive a live view image captured by the electronic device through wired or wireless communication and display the live view image.

In this case, the program and a storage medium storing the program constitute the present application.

[0217] According to the present application, a user can more easily recognize a change in an internal state of a device and a change in a temperature of the device due to the change in the internal state.
