[0011] Hereinafter, an electronic device according to an embodiment of the present invention will be described with reference to the drawings. The electronic device 1 according to the first embodiment is, for example, an imaging device for observing and photographing the cervix at the back of a human vagina, and is a camera used in so-called colposcopy. In the following description, the imaging target (subject) side shown in FIG. 1 is defined as the front (front face) of the electronic device 1, the opposite side is defined as the rear, and the description will be based on an orthogonal coordinate system in which the up, down, left, and right directions when viewing the electronic device 1 from the rear are defined as the up, down, left, and right directions. That is, the right side of the electronic device 1 is usually held by the user's right hand, and the left side is held by the user's left hand.

[0012] As shown in FIGS. 1 and 2, the electronic device 1 includes a housing 10 (forming the electronic device main body) that houses the various components of the electronic device 1, and a display unit 40 rotatably attached to the upper edge of the rear surface 10c of the housing 10. The housing 10 has a generally rectangular shape when viewed from the front. A first handle 10a that protrudes forward is formed on the right side of the front surface of the housing 10. The tip of the first handle 10a has a front surface 10e that is a plane perpendicular to the front-to-rear direction. A cylindrical second handle 10b that protrudes forward is formed in the approximate center of the front surface of the housing 10. The first handle 10a is a portion that is gripped by the user's right hand when using the electronic device 1. The second handle 10b is a portion that is gripped between the thumb and index finger of the user's left hand when using the electronic device 1. By gripping the first handle 10a and the second handle 10b in this manner, the electronic device 1 is held in a stable state. As shown in Fig. 2, the display unit 40 is, for example, a touch panel type liquid crystal monitor, and displays various operational information, captured images, etc., and accepts user operations. By rotating the display unit 40 around the upper edge portion as an axis, it is possible to change the position between a state in which at least a portion of the rear surface 10c of the housing 10 is covered (stored state, closed state) as shown in Fig. 2, and a state in which the rear surface 10c of the housing 10 is exposed (rotated state, open state) as shown in Fig. 3. This allows the user to adjust the angle of the display unit 40 to a position that is easy to view.

[0013] The surface of the housing 10 is provided with a plurality of operation buttons 21-26 as input units. As shown in FIG. 2, an operation button 21 serving as a shutter button and an operation button 22 serving as an EV (Exposure Value) button for adjusting brightness are provided on the upper right side of the housing 10. An operation button 23 serving as a power button is provided to the left of the operation button 22. As shown in FIG. 2, the rear surface 10c of the housing 10 is provided with an operation button 24 for adjusting the zoom at the upper right side, an operation button 25 below that as a mode button for changing the imaging mode, and an operation button 26 below that for playing captured still images and videos on the display unit 40. As shown in FIG. 1, a cover 10d for covering the hollow portion of the second handle portion 10b is provided on the front end surface of the second handle portion 10b. Four openings are formed in this cover 10d. The central opening houses the imaging lens 15 of the imaging unit 16 (FIG. 4). Furthermore, three light emitting units 31, 32, and 33 are provided as the light emitting unit 30 (FIG. 4) in three openings formed to surround the central imaging lens 15.

[0014] The imaging lenses 15 shown in FIG. 1 are arranged in a plurality along the optical axis (front-rear direction). The imaging lenses 15 are interposed between an imaging target and an imaging element (not shown) and form an image of the target on the imaging element. The imaging lenses 15 are movable in the front-rear direction, which changes the focal length and the magnification. The imaging unit 16 shown in FIG. 4 includes the imaging lenses 15 and the imaging element and can capture an image of the target using the imaging element. The light-emitting unit 31 is located at the upper right of the imaging lens 15 (upper left when viewed from the front) as shown in FIG. 1. The light-emitting unit 31 is a white light used for normal imaging of the target. The light-emitting unit 32 is located below the imaging lens 15. The light-emitting unit 32 is a polarized light that emits light that has passed through a polarizing plate (not shown). The light-emitting unit 33 is located at the upper left of the imaging lens 15 (upper right when viewed from the front). The light-emitting unit 33 is a green light that emits green light toward the target.

[0015] The electronic device 1 also has eight temperature sensors 71 to 78 as a temperature detection unit. Each of the temperature sensors 71 to 78 is provided near the outer surface of the electronic device 1. The eight temperature sensors 71 to 78 may be simply referred to as a temperature sensor 70. As shown in FIG. 1, the temperature sensor 71 is provided, for example, near the operation button 21 and the operation button 22. Temperature data detected by the temperature sensor 71 is used to estimate the surface temperature of a temperature estimation area 91 shown in FIG. 1, which is centered on the operation button 21 and the operation button 22. In FIG. 1, the temperature estimation area 91 is hatched to make it easy to understand. Other temperature estimation areas described below are also hatched in the same way. The temperature estimation area 91 is set as an area that is likely to be touched or likely to be touched by the user's finger when pressing the operation button 21 and the operation button 22.

[0016] 2, the temperature sensor 72 is provided, for example, between the operation button 24 and the operation button 25. The temperature data detected by the temperature sensor 71 is used to estimate the surface temperature of the right area of ​​the rear surface 10c of the housing 10, that is, a temperature estimation area 92 shown in FIG. 2 centered on the operation buttons 24, 25, and 26. This temperature estimation area 92 is set as an area that is likely to be touched or that the user's fingers will touch when pressing the operation buttons 24, 25, and 26.

[0017] The temperature sensor 73 is provided, for example, near the front surface 10e of the first handle portion 10a, as shown in Fig. 1. The temperature data detected by the temperature sensor 73 is used to estimate the surface temperature of the front surface 10e of the first handle portion 10a, i.e., the temperature estimation area 93 shown in Fig. 1. This temperature estimation area 93 is set as an area that is likely to be touched or likely to be touched by the hand of a user holding the first handle portion 10a.

[0018] The temperature sensor 74 is provided, for example, on the second handle portion 10b, as shown in Fig. 1. Temperature data detected by the temperature sensor 74 is used to estimate the surface temperature of the outer circumferential surface of the second handle portion 10b, i.e., the temperature estimation area 94 shown in Fig. 1. This temperature estimation area 94 is set as an area that is likely to be touched or likely to be touched by the hand of a user holding the second handle portion 10b.

[0019] As shown in Fig. 1, temperature sensor 75 is provided in the left region on the front surface of housing 10. Temperature data detected by temperature sensor 75 is used to estimate the surface temperature of the left region on the front surface of housing 10, i.e., temperature estimation region 95 shown in Fig. 1. This temperature estimation region 95 is set as an area that is likely to be touched or likely to be touched by a user's hand gripping second handle portion 10b or a user's hand gripping the left end of housing 10.

[0020] As shown in Fig. 1, the temperature sensor 76 is provided near the light-emitting elements 31, 32, and 33. Temperature data detected by the temperature sensor 76 is used to estimate the surface temperature of the outer surface of the cover 10d of the second handle portion 10b, i.e., the temperature estimation area 96 shown in Fig. 1. This temperature estimation area 96 is close to the light-emitting elements 31, 32, and 33 and is set as an area that is likely to become hot while the electronic device 1 is in use. However, it is not recommended to touch the temperature estimation area 96, regardless of whether the electronic device 1 is in use or not, and touching this area will not cause any problems in use.

[0021] The temperature sensor 77 is provided near the display panel 40a as shown in Fig. 2. Temperature data detected by the temperature sensor 77 is used to estimate the surface temperature of the outer surface of the display panel 40a, i.e., the temperature estimation area 97 shown in Fig. 2. This temperature estimation area 97 is set as an area where the user's hand will or is likely to touch the display panel 40a while the electronic device 1 is in use.

[0022] As shown in Fig. 3, the temperature sensor 78 is provided on the rear surface 10c of the housing 10. Temperature data detected by the temperature sensor 78 is used to estimate the surface temperature of a part of the outer surface of the rear surface 10c, i.e., a temperature estimation area 98 shown in Fig. 3. The temperature estimation area 98 is an area that is covered by the display unit 40 when the display unit 40 is rotated closed. This temperature estimation area 98 is set as an area that is likely to be touched or likely to be touched by the hand of a user holding the electronic device 1.

[0023] Next, with reference to FIG. 4, the functions of each unit included in the electronic device 1 will be described. The electronic device 1 includes a control unit 50, a storage unit 53, a temperature sensor 70, an input unit 20, a rotation sensor 80, an imaging unit 16, a display unit 40, a power supply unit 54, and a light-emitting unit 30. The control unit 50 is configured with a CPU (Central Processing Unit) and other components, and executes programs stored in the storage unit 53 to control the imaging unit 16, the display unit 40, the power supply unit 54, and the light-emitting unit 30. The control unit 50 also includes a timer 51. The control unit 50 can determine the current date and time from time information read from the timer 51. The storage unit 53 includes a ROM (Read Only Memory), a RAM (Random Access Memory), and other components, and stores the programs executed by the control unit 50, necessary data, and the like. For example, the storage unit 53 includes a database that records the temperature measured by the temperature sensor 70 and the time of measurement. The temperature sensor 70 transmits the measured temperature data to the control unit 50. The temperature sensor 70 includes, for example, temperature sensors 71 to 78. The input unit 20 is a user interface such as a push button switch and accepts operation input from the user. The input unit 20 includes, for example, operation buttons 21 to 26 and a touch panel LCD monitor. The rotation sensor 80 detects whether the display unit 40 is in the retracted state shown in FIG. 2 or the rotated state shown in FIG. 3. The detection result of the rotation sensor 80 is transmitted to the control unit 50. The imaging unit 16 includes, for example, an imaging element such as a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor. The imaging unit 16 captures still images and videos by converting light that has passed through the imaging lens 15 shown in FIG. 1 into an electrical signal. The display unit 40 displays various images under the control of the control unit 50. The display unit 40 includes a touch panel display panel 40a. The power supply unit 54 includes a battery 55 that stores power. The power supply unit 54 supplies power to each component of the electronic device 1 under the control of the control unit 50. The battery 55 may be, for example, removable by the user or may not be removable.Furthermore, the power supply unit 54 may be capable of receiving power from an external power source instead of being equipped with a battery 55. The light emitting unit 30 has three light emitting units 31, 32, and 33 shown in FIG. 1 arranged around the optical axis of the imaging lens 15. The control unit 50 selectively causes the three light emitting units 31, 32, and 33 to emit light, irradiating the subject to be photographed. In this way, the light emitting unit 30 functions as a light source.

[0024] Next, a warning operation, which is one of the functions of the control unit 50, will be described. The control unit 50 includes a warning operation determination unit 52. The warning operation determination unit 52 is realized by software, firmware, or a combination of software and firmware. The software and firmware are written as programs and stored in the storage unit 53. The control unit 50 then executes the programs stored in the storage unit 53 to perform warning operation processing.

[0025] The warning operation determination unit 52 acquires temperature data from the temperature sensor 70. The warning operation determination unit 52 records a history of the acquired temperature and the measurement time in the storage unit 53. If the temperature sensor 70 determines that a temperature equal to or higher than a predetermined temperature has been continuously measured for a predetermined time (predetermined period), the warning operation determination unit 52 determines the warning operation to be performed. At this time, it is assumed that the surface temperature of the electronic device 1 is rising due to heat generation during use. The warning operation determination unit 52 controls the display unit 40 and the power supply unit 54 to perform the determined warning operation. Note that the specific content of the warning operation and the conditions for executing the warning operation are set for each temperature sensor 70. However, the temperature sensor 70 is provided inside the housing 10 and does not directly measure the surface temperature of the electronic device 1. Therefore, the temperature measured by the temperature sensor 70 indicates a value different from the surface temperature of the electronic device 1. However, since the mounting conditions of the temperature sensor 70 and the thermal conductivity between the surface of the electronic device 1 and the temperature sensor 70 can be known, it is easy to estimate (back-calculate) the surface temperature of the electronic device 1 from the data acquired from the temperature sensor 70. Alternatively, the relationship between the surface temperature of the electronic device 1 and the temperature measured by the temperature sensor 70 may be determined directly through an experiment. The relationship between the temperature measured by the temperature sensor 70 and the warning operation will be described below, but for the sake of simplicity and ease of understanding, the description will be made assuming that the temperature measured by the temperature sensor 70 and the surface temperature of the electronic device 1 are equal.

[0026] The temperature sensor 71 is provided to estimate the temperature of a temperature estimation area 91 that is likely to be touched by the user's finger when pressing the operation buttons 21 and 22. As shown in FIG. 5 , when the temperature sensor 71 measures a temperature of 46°C or higher continuously for 40 minutes, the warning operation determination unit 52 determines that the notification condition is met and executes warning display 1, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message (alert information) "The temperature of the button is rising" on the display unit 40 to notify the user. This warning display indicates the status of the electronic device 1. Furthermore, when the temperature sensor 71 measures a temperature of 48°C or higher continuously for one minute, the warning operation determination unit 52 executes warning display 2, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message (alert information) "Turn off the power and leave it for a while" on the display unit 40 to notify the user. This display indicates the corrective action that the user should take. Furthermore, if the temperature sensor 71 measures a temperature of 50°C or higher for one minute continuously, the warning operation determination unit 52 causes the power supply unit 54 to turn off the power to the electronic device 1. Note that the warning operation, Warning Display 1, is a preliminary operation that is executed in a situation where the temperature has not risen below the temperature of Warning Display 2. In this way, by executing Warning Display 1, Warning Display 2, and the operation of turning off the power, burns that may occur when touching the temperature estimation area 91 can be prevented in advance.

[0027] 2, temperature sensor 72 is provided to estimate the temperature of temperature estimation area 92 that is likely to be touched or that the user's finger will touch when pressing operation buttons 24, 25, and 26. Note that, as shown in FIG. 5, the content of the warning operation based on the temperature measured by temperature sensor 72 is the same as the content of the warning operation based on the temperature measured by temperature sensor 71.

[0028] As shown in FIG. 1, the temperature sensor 73 is provided to estimate the temperature of a temperature estimation region 93 that is likely to be touched by the user's hand while holding the first handle portion 10a. As shown in FIG. 5, when the temperature sensor 73 continuously measures a temperature of 46°C or higher for 40 minutes, the warning operation determination unit 52 determines that the notification condition is met and executes warning display 1, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40 saying, "The temperature around the handle is rising," to notify the user. Furthermore, when the temperature sensor 73 continuously measures a temperature of 48°C or higher for one minute, the warning operation determination unit 52 executes warning display 2, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40 saying, "Turn off the power and leave it for a while," to notify the user. Furthermore, when the temperature sensor 73 continuously measures a temperature of 50°C or higher for one minute, the warning operation determination unit 52 causes the power supply unit 54 to turn off the power to the electronic device 1.

[0029] As shown in Fig. 1, temperature sensor 74 is provided to estimate the temperature of temperature estimation area 94 that is likely to be touched or that the user's hand will touch while holding second handle portion 10b. Note that, as shown in Fig. 5, the content of the warning action based on the temperature measured by temperature sensor 74 is the same as the content of the warning action based on the temperature measured by temperature sensor 73.

[0030] 1, temperature sensor 75 is provided to estimate the temperature of temperature estimation area 95 that is likely to be touched or reached by a user's hand holding second handle portion 10b or a user's hand holding the left end of housing 10. As shown in FIG. 5, the warning action based on the temperature measured by temperature sensor 75 is the same as the warning action based on the temperature measured by temperature sensor 73.

[0031] As shown in FIG. 1 , the temperature sensor 76 is provided to estimate the temperature of a temperature estimation region 96 that is close to the light-emitting units 31, 32, and 33 and that is prone to become hot during use of the electronic device 1. As shown in FIG. 5 , when the temperature sensor 76 continuously measures a temperature of 48°C or higher for one minute, the warning operation determination unit 52 determines that the notification condition is met and executes a warning display, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40, reading "Do not touch the area around the light-emitting units," to notify the user. Although the temperature estimation region 96 is prone to become hot due to the heat from the light-emitting units 31, 32, and 33, it is not necessary to touch the temperature estimation region 96 during use. Furthermore, since the electronic device 1 is kept away from the subject during imaging, and the region does not come into contact with the patient, only one warning operation is required; a second warning display and a power-off warning are not executed.

[0032] As shown in FIG. 2 , the temperature sensor 77 is provided to estimate the temperature of a temperature estimation area 97 where a user's hand is likely to touch the display panel 40a while the electronic device 1 is in use. As shown in FIG. 5 , when the temperature sensor 77 continuously measures a temperature of 46°C or higher for 40 minutes, the warning operation determination unit 52 determines that the notification condition is met and executes warning display 1, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40 saying, "The temperature of the display unit is rising," to notify the user. Furthermore, when the temperature sensor 77 continuously measures a temperature of 48°C or higher for one minute, the warning operation determination unit 52 executes warning display 2, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40 saying, "Do not touch the display unit," to notify the user. Furthermore, when the temperature sensor 77 continuously measures a temperature of 50°C or higher for one minute, the warning operation determination unit 52 causes the power supply unit 54 to turn off the power to the electronic device 1.

[0033] As shown in FIG. 3 , the temperature sensor 78 is provided on the rear surface 10c of the housing 10 to estimate the temperature of a temperature estimation region 98 that is likely to be touched by a user holding the electronic device 1. As shown in FIG. 5 , when the temperature sensor 78 continuously measures a temperature of 46°C or higher for 40 minutes and the rotation sensor 80 determines that the display unit 40 is rotated, the warning operation determination unit 52 determines that the notification conditions are met and executes Warning Display 1, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40 saying, "The temperature of the main body is rising," to notify the user. Furthermore, when the temperature sensor 78 continuously measures a temperature of 48°C or higher for 1 minute and the rotation sensor 80 determines that the display unit 40 is rotated, the warning operation determination unit 52 executes Warning Display 2, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40 saying, "Please close the display unit," to notify the user. That is, the user is notified to store the display unit 40. Furthermore, if the temperature sensor 78 measures a temperature of 50°C or higher for one minute continuously and the rotation sensor 80 determines that the display unit 40 is rotated, the warning operation determination unit 52 causes the power supply unit 54 to turn off the power to the electronic device 1. By closing the display unit 40 in accordance with the warning message "Please close the display unit," the high-temperature temperature estimation area 98 can be covered with the display unit 40.

[0034] The warning operation process will be described below with reference to a flowchart (FIG. 6). When the electronic device 1 is powered on, the control unit 50 acquires temperature data from the temperature sensor 70 (step S101). In this embodiment, temperature data is acquired from eight temperature sensors 71 to 78. The control unit 50 records the temperature measured by the temperature sensor 70 and the measurement time in the database of the storage unit 53. Next, the control unit 50 refers to the database of the storage unit 53 and determines whether or not there is at least one temperature data item that should be warned among the acquired temperature data (step S102). Temperature data that should be warned is temperature data that indicates a temperature equal to or higher than a predetermined temperature shown in FIG. 5. If the control unit 50 determines in step S102 that there is no temperature data item that should be warned (step S102: No), the control unit 50 returns the process to step S101. On the other hand, if the control unit 50 determines in step S102 that there is at least one temperature data item that should be warned (step S102: Yes), the control unit 50 proceeds to step S103. Next, the control unit 50 refers to the database in the storage unit 53 and determines whether any of the temperature data subject to the warning (hereinafter, the warning data) has continued for a predetermined period of time as shown in FIG. 5 (step S103). The control unit 50 can determine whether any of the temperature data has continued for a predetermined period of time based on the time when the warning occurred and the current time. If it is determined that any of the temperature data has continued for a predetermined period of time (step S103: Yes), the control unit 50 determines a corresponding warning action (FIG. 5) (step S104). Note that, if the data that has continued for a predetermined period of time is from the temperature sensor 78 in step S104, the control unit 50 determines the warning action only when the display unit 40 is in a rotated state. Next, the control unit 50 determines whether any of the determined warning actions includes a power-off action (step S105). If the power-off action is included (step S105: Yes), the control unit 50 controls the power supply unit 54 to turn off the power to the electronic device 1 (S107). This ends the warning action process. On the other hand, if the power-off action is not included (step S105: No), the control unit 50 displays the warning message indicated by the determined warning action on the display unit 40 (step S106). Then, the control unit 50 proceeds to step S101.In step S106, for example, if the temperature sensor 71 measures a temperature of 46 degrees or higher for 40 minutes or more, the control unit 50 displays, for example, a warning display 35 shown in FIG. 7 on the display unit 40. This warning display 35 has a warning message display unit 35a that displays the warning message shown in FIG. 5, and a warning location display unit 35b that indicates the part of the electronic device 1 where the temperature has risen. The warning message display unit 35a displays, for example, the phrase "The temperature of the button is rising." The warning location display unit 35b displays an image of the electronic device 1 and an arrow that indicates the part of the electronic device 1 where the temperature is rising.

[0035] According to the above embodiment, the electronic device 1 includes temperature sensors 71-78 that measure the temperature of the electronic device 1. When temperature data acquired from the temperature sensors 71-78 satisfies a notification condition indicating a predetermined temperature range corresponding to a temperature measurement target portion of the electronic device 1, the electronic device 1 selects at least one notification information from among the status of the electronic device 1 and a countermeasure to be taken by the user and notifies the user. Therefore, the user who receives the notification can properly understand the status of the electronic device 1. Furthermore, because the countermeasure is displayed, the user can take action by following the displayed countermeasure without confusion. Since this warning operation is related to the elevated temperature of the electronic device 1, it can protect the user from burns and low-temperature burns. Furthermore, since the notification condition is determined according to the measurement target portion, it is possible to protect the user from burns, low-temperature burns, etc. by taking into account the characteristics of the measurement target portion, and it is also possible to suppress the notification of inappropriate notification information. Furthermore, the electronic device 1 is configured so that the notification condition is satisfied when the temperature data indicates a predetermined temperature range for a predetermined period of time. This allows not only the temperature data but also the period during which the predetermined temperature is reached to be taken into consideration, thereby enabling appropriate notification information to be notified. The electronic device 1 also includes a display unit 40 that can rotate between a rotated state and a retracted state relative to the electronic device body. When the control unit 50 determines that the temperature of the electronic device body is not suitable for the user to hold the electronic device 1 while the display unit 40 is rotated, the control unit 50 notifies the user to change the display unit 40 from the rotated state to the retracted state. As shown in FIG. 3 , when the display unit 40 is rotated and a portion of the electronic device accessible by the user's hand (temperature estimation area 98) is hot, the control unit 50 prompts the user to close the display unit 40 to prevent the user from touching the portion. This protects the user from burns, low-temperature burns, and the like. The temperature sensors 71-78 are provided at multiple locations on the electronic device 1, and notification conditions are set for each of the temperature sensors 71-78. Therefore, the notification conditions can be set according to the mounting conditions of the temperature sensors 71-78. Specifically, the notification conditions can be set taking into account the installation location of the temperature sensors, i.e., the depth from the surface of the electronic device 1 and the thermal conductivity of the installation location.For example, if a temperature sensor is installed deep beneath the surface of the electronic device 1 or in a location with low thermal conductivity, it is expected that the measured temperature data will be lower than the estimated surface temperature of the electronic device 1. The notification conditions for each temperature sensor can be set taking into account this difference from the actual measured value. Furthermore, temperature sensors 71-78 are installed in multiple locations on the electronic device 1, and each of the temperature sensors 71-78 is configured to notify the content of the notification when the notification conditions are met. This allows the content of the notification to vary depending on the location measured by the temperature sensor. For example, as shown in FIG. 5, a specific location where the temperature is rising can be notified, specifically, a temperature rise around the button, the handle, or the LED light. Furthermore, a specific response appropriate to the location where the temperature is rising can be notified, specifically, by suggesting that the power be turned off or the display unit 40 be closed. Furthermore, if the temperature data acquired from the temperature sensors 71-75, 77, and 78 satisfies the notification conditions and continuously indicates a predetermined temperature or higher, the electronic device 1 is powered off. This is the power-off warning operation shown in FIG. 5. This automatically turns off the power of the electronic device 1 before the user is likely to be burned by touching the electronic device 1. Before the power is turned off, the device notifies the user of either the status of the electronic device 1 or the corrective action the user should take. This prevents the user from becoming confused because they do not understand why the power was turned off. Furthermore, temperature sensors 71-78 are provided in multiple locations on the electronic device 1. Among the multiple temperature sensors 71-78, temperature sensor 76 does not have a condition for turning off the power of the electronic device 1. This prevents the electronic device 1 from being turned off every time it is used, preventing the user from using the electronic device 1 when desired. Furthermore, temperature sensor 76, which measures temperature data for which a condition for turning off the power of the electronic device 1 is not set, measures the temperature of a portion of the electronic device 1 that does not interfere with normal use even if the user does not touch it. This allows the user to use the electronic device 1 without touching a hot portion when holding or operating the electronic device 1.On the other hand, as shown in FIG. 5, before the temperature reaches a high level, a warning message "Do not touch the area around the LED light" is displayed, thereby making the user aware that the area is getting hot. The electronic device 1 is an imaging device including an imaging unit 16 for capturing images, a display unit 40 for displaying the captured images, an input unit 20 for receiving operational inputs, and handle units 10a and 10b. Temperature sensors 71-78 measure the temperature of at least one of the input unit 20, the display unit 40, and the handle units 10a and 10b. This allows the effects of the present invention to be achieved even when applied to an imaging device. Furthermore, when temperature data acquired from the temperature sensor satisfies a notification condition, an image is displayed on the display unit 40 to notify the user of the status of the electronic device 1 and at least one of the corrective measures to be taken by the user. This allows the user to properly understand the status of the imaging device and corrective measures simply by checking the display content on the display unit 40. Furthermore, as shown in FIG. 7, the warning display on the display unit 40 includes a warning text display section 35a and a warning location display section 35b, so that the user can intuitively understand the content of the warning and which part of the electronic device 1 they should pay attention to.

[0036] Next, an electronic device 101 according to a second embodiment will be described with reference to FIG. 8. The electronic device 101 is an imaging device that captures images for observing skin conditions (lesions, etc.), such as a camera used in dermoscopy. The electronic device 101 has much in common with the electronic device 1 of the first embodiment. Therefore, the following description focuses on the differences, and the common components will be omitted. In the above embodiment, as shown in FIG. 8, the front end surface of the second handle 10b is provided with a cover 110 formed in a cylindrical, truncated cone shape, and a plurality of light-emitting elements 112 arranged around the cover 110. The cover 110 has an objective cover 111 fitted into an opening 110a at its top (front end). The objective cover 111 is made of a light-transmitting material, such as glass, and is formed in a disk shape. The objective cover 111 is disposed so that its main surface is perpendicular to the optical axis. When performing dermoscopy on a skin observation area (a region of the skin to be observed), gel is applied to the skin observation area to be imaged, and the objective cover 111 is pressed against the gel. This blocks the air layer between the skin observation area and the objective cover 111, making it possible to suppress diffuse reflection of light on the skin surface.

[0037] The housing 10 is provided inside with an imaging unit (not shown) and a light-emitting unit that emits UV light and polarized light. The objective cover 111, pressed against the skin observation unit, transmits light from the light-emitting unit (not shown), irradiating the skin observation unit with light, and also allows light reflected by the skin observation unit to enter and guide it to the imaging unit. The light-emitting unit 112 is, for example, an LED that emits white light, and functions as a ring flash that emits light forward from the outer periphery of the cover unit 110. The light-emitting unit 112 emits light to illuminate the skin observation unit when observing and photographing the skin observation unit (normal photography) with the electronic device 101 as a general camera.

[0038] Of the eight temperature sensors 71 to 78 provided in the electronic device 1 of the first embodiment, the electronic device 101 is provided with seven temperature sensors 71 to 77. The electronic device 1 further has a temperature sensor 79 as a temperature detection unit. As shown in FIG. 8, the temperature sensor 79 is provided, for example, near the objective cover 111. Temperature data detected by the temperature sensor 79 is used to estimate the surface temperature of a temperature estimation region 99 shown in FIG. 8, which is centered on the objective cover 111. This temperature estimation region 99 is set as an area that comes into contact with a skin observation portion when the skin observation portion is photographed by dermoscopy.

[0039] As shown in FIG. 5 , when the temperature sensor 79 measures a temperature of 43° C. or higher for 10 consecutive minutes, the warning operation determination unit 52 determines that the notification condition is met and executes warning display 1, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40 saying, "The temperature around the light-emitting unit is rising," to notify the user. Furthermore, when the temperature sensor 79 measures a temperature of 48° C. or higher for 9 consecutive minutes, the warning operation determination unit 52 executes warning display 2, which is a warning operation. Specifically, the warning operation determination unit 52 displays a warning message on the display unit 40 saying, "Turn off the power and leave it for a while," to notify the user. Furthermore, when the temperature sensor 79 measures a temperature of 50° C. or higher for 1 consecutive minute, the warning operation determination unit 52 causes the power supply unit 54 to turn off the power to the electronic device 1.

[0040] According to this embodiment, the electronic device 1 is an imaging device including an imaging unit 16 and an objective cover 111 that is pressed against the skin portion of the imaging target and directs light reflected from the skin portion to the imaging unit 16. The temperature sensor 79 measures the temperature of the objective cover 111 at the skin portion, and the control unit 50 is configured to issue a warning to the user if it is determined that the temperature measured by the temperature sensor 79 is within a temperature range that may affect the skin portion. The objective cover 111 directly contacts the skin observation portion to capture an image. Therefore, considering that the objective cover 111 directly contacts the skin, the predetermined temperature (43°C or higher), which is one element of the warning criteria, is set lower than that of other temperature sensors. If a temperature of 43°C or higher is measured continuously for 10 minutes or more, a warning message is displayed. This warning is issued when it is determined that if the objective cover 111 is pressed against the skin portion continuously, the temperature will be within a range that may affect the skin portion, such as a low-temperature burn. Meanwhile, imaging of the skin observation portion is performed by a doctor or medical professional who has learned the appropriate operation method. By displaying the warning message, the doctor or medical personnel can be made aware of the current device status and can properly capture images of the skin observation area. Furthermore, if the temperature sensor 79 measures a temperature of 48°C or higher for nine minutes or more, warning message 2, "Turn off the power and notify for a while," is displayed, allowing the doctor or medical personnel to recognize that the temperature of the electronic device 1 has further increased. This warning is issued when it is determined that the temperature falls within a range that could cause a low-temperature burn or other adverse effect on the skin if the objective cover 111 is pressed against the skin even for a short period of time. Furthermore, if the temperature detected by the temperature sensor 79 exceeds 50°C and continues for more than one minute, the electronic device 1 is turned off. This prevents the hot objective cover 111 from coming into contact with the skin observation area.

[0041] The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. In the above-described embodiment, the electronic device 1,101 is described as a medical camera such as a dermatoscope or a colposcopy camera, but the technology of the present invention can be applied to any electronic device. For example, the present invention can be applied to general-purpose cameras such as single-lens reflex cameras, video cameras, smartphones and tablets with camera functions, laptop computers, etc.

[0042] Furthermore, in the first and second embodiments, eight temperature sensors are attached, but the number of temperature sensors to be attached is arbitrary, and more temperature sensors may be attached in various locations, or fewer temperature sensors may be attached to facilitate control. In the present embodiment, the warning indicating that the temperature is rising is displayed by the display unit 40, but the manner of notification is not particularly limited. For example, a speaker may be provided in the electronic device 1, and the warning may be issued by this speaker. Furthermore, the warning may be issued by using both the display unit 40 and the speaker. The attachment positions of the temperature sensors 71 to 79 are merely examples, and the temperature sensors may be attached at any location as long as the surface temperature of the electronic device 1 can be estimated.

[0043] Furthermore, the content of the warning displayed on the display unit 40 is not particularly limited. For example, the time remaining until the power is forcibly turned off if the device is used as is may be displayed, or a warning to be displayed thereafter may be announced. Also, although only one warning is displayed in FIG. 7, if a warning needs to be issued based on measurement data from multiple temperature sensors 70, multiple warnings may be displayed simultaneously. Also, an explanatory video may be displayed on the display unit 40, or symbols indicating cautions and warnings may be displayed.

[0044] Furthermore, as shown in FIG. 5, the temperature and duration at which a warning is issued for the measurement data of temperature sensors 71-75, 77, and 78 are the same. However, these values ​​may be different. For example, differences in the sensor mounting conditions (depth from the surface, thermal conductivity) may be reflected. For example, if right-handed people tend to hold electronic device 1 by gripping handle portion 10a for a long time, the predetermined temperature for issuing a warning may be lowered or the predetermined duration may be shortened, for example, in the measurement data of temperature sensors 72 and 73. Alternatively, if left-handed people tend to hold electronic device 1 by gripping handle portion 10b for a long time, the predetermined temperature for issuing a warning may be lowered or the predetermined duration may be shortened, for example, in the measurement data of temperature sensors 74 and 75. Furthermore, the warning may be executed only if the temperature of the temperature sensor indicates a predetermined temperature range, regardless of the predetermined duration.

[0045] Furthermore, in the above-described embodiment, the program executed by the control unit 50 of the electronic device 1 can also be applied to an existing computer. This makes it possible to cause the computer to function as a device having the warning means determination unit according to the present disclosure. Such a program can be distributed in any manner, and may be stored on a computer-readable recording medium such as a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), an MO (Magneto Optical Disk), or a memory card, or may be distributed via a communication network such as the Internet or an intranet.
