Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when considering providing a plurality of continuous shooting modes with different continuous shooting speeds for continuous shooting imaging, the user can easily perform continuous shooting at a continuous shooting speed suitable for the use case by switching between the plurality of continuous shooting modes, which is convenient. If continuous shooting modes such as high speed, medium speed, and low speed can be selected as in Patent Document 1 above, it becomes easier to perform continuous shooting according to the situation and shooting purpose. However, the actual shooting situations and subjects are diverse, and there is also a desire to select the continuous shooting speed more flexibly. In the technology of Patent Document 1 above, although three types of continuous shooting speeds can be switched by mode switching, the user cannot flexibly set the continuous shooting speed of each mode according to their preferences and situations.

[0005] Therefore, this disclosure proposes to allow users to more flexibly set frame rates, such as continuous shooting speed, which can be switched depending on the mode. [Means for solving the problem]

[0006] The imaging device according to this technology has a selection of frame rates that are the same as other frame rate modes for all or some of the multiple frame rate modes, and includes a control unit that sets the frame rate for each of the multiple frame rate modes from the selection in response to operation. The control unit performs control to present frame rate options as a value indicating the number of still images to be recorded per unit of time. For example, multiple frame rate modes are provided so that the user can select the frame rate as the continuous shooting speed. In this case, the user can set the frame rate in all or some of the frame rate modes. In this case, for example, the frame rate could be displayed on a settings screen where the user can adjust the frame rate, using a display such as fps (frames per second) or the number of still images per second. The frame rate can be either the frame rate of the video capture or the frame rate of the live view image.

[0007] In the imaging device relating to the present technology described above, it is conceivable that each of the multiple frame rate modes for which a frame rate can be selected has the same selection options. For example, if frame rates are selectable in three frame rate modes, the same options will apply to all three frame rate modes.

[0008] In the imaging device relating to the present technology described above, the control unit may have the display unit display the relative relationship between the frame rates for each of the multiple frame rate modes for which the frame rate can be selected. For example, the three frame rate modes could be displayed as "Hi," "Mid," and "Lo," clearly indicating the difference in frame rate to the user.

[0009] In the imaging device relating to the present technology described above, the control unit may, for multiple frame rate modes in which the frame rate can be selected, display the relative high-low relationship of each frame rate, and enable variable setting of the frame rate for each frame rate mode within a range in which the relative relationship of the frame rates set for each frame rate mode does not reverse with respect to the displayed relative high-low relationship. For example, when displaying three frame rate modes such as "Hi," "Mid," and "Lo" to show the user the difference between high and low frame rates, the system should prevent users from selecting a frame rate mode where the "Mid" frame rate is faster than the "Hi" frame rate mode.

[0010] In the imaging device relating to the above-described technology, the control unit may perform control to display, on the frame rate setting screen of the frame rate mode, any frame rates that it has determined cannot be selected in the target frame rate mode as unavailable. In other words, when displaying frame rate options for a given frame rate mode to the user, the control unit determines the selectable options according to the settings of adjacent frame rate modes in terms of frame rate relative to each other.

[0011] In the imaging device relating to the above-described technology, the control unit may perform control to display, on the frame rate setting screen of the frame rate mode, any frame rates that it has determined cannot be selected in the target frame rate mode as unavailable. For example, frame rates that cannot be selected from the options will be displayed in a grayed-out state.

[0012] In the imaging device relating to the above-described technology, the control unit may perform a process to return the frame rate settings for multiple selectable frame rate modes to their initial state in response to a setting initialization operation. In other words, it allows the user to perform initialization operations regarding the frame rate mode.

[0013] In the imaging device relating to the above-described technology, the control unit may perform control to display the current frame rate setting value for each frame rate mode on the frame rate setting screen of the frame rate mode. For example, the settings screen displayed when a user selects a frame rate should show the current frame rate settings for each frame rate mode.

[0015] In the imaging device relating to the above-described technology, the control unit may perform control that allows the frame rate to be selected by specifying the number of still images to be recorded per unit time. For example, we provide a user interface that allows the user to specify the number of still images to record per second.

[0016] In the imaging device relating to the above-described technology, the control unit may perform control that allows the frame rate to be selected by specifying the number of still images to be recorded per unit time using a cursor on a gauge. For example, it provides a user interface that allows the user to specify the number of still images to record per second on the gauge.

[0017] In the imaging device relating to the above-described technology, the control unit may perform control to execute a display that allows frame rate settings for multiple frame rate modes to be set within a single screen. For example, a gauge that allows for variable frame rate settings for multiple frame rate modes can be displayed on a single screen.

[0018] In the imaging device relating to the above-described technology, it is conceivable to further include an operator for selecting imaging operation modes, including multiple frame rate modes and a single-shot mode. In other words, it will be possible to switch between a single-shot mode for recording a single still image and multiple frame rates (for example, a continuous shooting mode) using the same control.

[0019] In the imaging device according to the present technology described above, as part of a plurality of frame rate modes, it is conceivable to provide a frame rate mode in which a frame rate that cannot be set in a plurality of frame rate modes with selectable frame rates is fixedly set. For example, a certain frame rate mode is set as a mode fixed to a high frame rate that cannot be set in other frame rate modes with variable frame rates.

[0020] In the configuration of the imaging device described above, it is conceivable that the plurality of frame rate modes are a plurality of continuous shooting modes, and the selectable frame rate is a frame rate corresponding to the continuous shooting speed. The imaging control method according to the present technology has options for frame rates that are the same as those of other frame rate modes for all or part of the plurality of frame rate modes, The frame rate options are presented as a value indicating the number of still images recorded per unit of time. depending on the operation Multiple and the imaging control device executes control to perform frame rate settings for each of the plurality of frame rate modes from a number of options. This is an imaging control method. Thereby, variable setting of the frame rate in a plurality of frame rate modes is performed. The program according to the present technology is a program that causes an arithmetic processing device to execute the above control. This makes it possible to easily realize the imaging device of the present disclosure.

[0022] The embodiments will be described below in the following order. <1. Configuration of the imaging device> <2. First Embodiment> <3. Second Embodiment> <4. Third Embodiment> <5.UI example> <6. Summary and Variations>

[0023] For the purposes of this disclosure, we will now explain the meanings of some of the terms used. "Imaging" refers to the operation of exposure by an image sensor and the reading out of the signals (image signals) from the exposed pixels. The image signals obtained through imaging are processed frame by frame to form image data that creates a still image. "Image recording" refers to the process of capturing still images in response to user shutter release operations, etc., and recording the captured still images onto a recording medium. For example, still image recording is performed in response to operations such as continuous shooting or single-shot shooting.

[0024] "Single-shot imaging" is the operation of capturing and recording a single still image in response to a release operation (for example, shutter operation). "Continuous shooting" is the operation of capturing and recording multiple still images while the shutter release is in progress (while the shutter button is pressed). In continuous shooting, "continuous shooting speed" refers to the rate at which still images are captured and recorded per unit of time. Therefore, continuous shooting speed can be expressed in notations such as "fps" or "10 frames / second".

[0025] "Image capture mode" is a general term encompassing modes including "single shot mode" and multiple "continuous shooting modes". "Single Shot Mode" is the mode used to perform single-shot imaging as described above. The "continuous shooting mode" is the mode used for continuous shooting as described above. In this embodiment, multiple continuous shooting modes with different continuous shooting speeds are provided. As an example of these multiple continuous shooting modes, "H+ mode," "H mode," "M mode," and "L mode" are provided. "H+ mode" is an abbreviation for "High+ mode," meaning ultra-high-speed mode. "H mode" is an abbreviation for "High mode," meaning high-speed mode. "M mode" is an abbreviation for "Middle mode," meaning a medium speed mode. "L mode" is an abbreviation for "Low mode," meaning low-speed mode. Furthermore, in this embodiment, multiple "continuous shooting modes" are assumed as multiple frame rate modes. For example, "H+ mode," "H mode," "M mode," and "L mode" are examples of frame rate modes. In that case, the frame rate set for each frame rate mode is the frame rate as the continuous shooting speed mentioned above.

[0026] <1. Configuration of the imaging device> The external appearance of the imaging device 1 according to this embodiment is shown in Figures 1 and 2. In the following explanation, the subject will be considered to be in the front and the photographer in the back.

[0027] As shown in Figures 1 and 2, the imaging device 1 comprises a camera housing 2 with the necessary parts arranged inside and outside, and a lens barrel 3 that is detachable from the camera housing 2 and attached to the front part 2a. Figure 2 shows the camera housing 2 with the lens barrel removed. It should be noted that the lens barrel 3 being detachable as a so-called interchangeable lens is just one example; it may also be a lens barrel that cannot be removed from the camera body 2.

[0028] A rear monitor 4 is located on the rear surface 2b of the camera housing 2. The rear monitor 4 displays live view images, playback images of recorded images, and more. The rear monitor 4 is comprised of a display device such as a liquid crystal display (LCD) or an electro-luminescent (OLED) display. The rear monitor 4 is rotatable relative to the camera housing 2. For example, the rear monitor 4 is rotatable so that its lower end moves backward, with its upper end as the pivot point. The right or left end of the rear monitor 4 may also be the pivot point. Furthermore, it may be rotatable in multiple directions around multiple axes.

[0029] An EVF (Electric Viewfinder) 5 is positioned on the upper surface 2c of the camera housing 2. The EVF 5 includes an EVF monitor 5a and a frame-shaped enclosure 5b that protrudes rearward, surrounding the EVF monitor 5a above and on both sides. The EVF monitor 5a is formed using an LCD or an organic EL display, etc. Alternatively, an optical viewfinder (OVF) may be provided instead of the EVF monitor 5a.

[0030] Various controls 6 are provided on the rear section 2b and the top section 2c. For example, these include a shutter button (release button), a playback menu activation button, a select button, a directional pad, a cancel button, a zoom key, a slide key, and so on. These controls 6 include various types, such as buttons, dials, and pressable and rotatable composite controls. These various types of controls 6 enable, for example, shutter operation, menu operation, playback operation, mode selection / switching operation, focus operation, zoom operation, and parameter selection / setting such as shutter speed and f-number.

[0031] One of these controls 6 is a mode selection dial 6a that allows the user to select the imaging operation mode. Figure 3 shows the imaging operation modes that can be selected using this dial 6a. As shown in the diagram, the following imaging modes are available: single shot mode, continuous shooting mode, self-timer mode, and bracket mode. Here, there are four continuous shooting modes available, each with a different continuous shooting speed: the aforementioned "H+ mode," "H mode," "M mode," and "L mode." In this embodiment, the continuous shooting speed is fixed in "H+ mode," but in "H mode," "M mode," and "L mode," the continuous shooting speed is set to be variable according to user operation.

[0032] The internal configuration of this imaging device 1 is shown in Figure 3. In the imaging device 1, light from the subject enters the image sensor 12, which is composed of, for example, a CMOS (Complementary Metal Oxide Semiconductor) sensor or a CCD (Charge Coupled Device) sensor, via the imaging optical system 11. The light is then converted into electricity by the image sensor 12, and an analog image signal is obtained from the image sensor 12.

[0033] The imaging optical system 11 is equipped with various lenses such as a zoom lens, a focus lens, and a condensing lens, as well as an aperture mechanism, a zoom lens drive mechanism, and a focus lens drive mechanism. A mechanical shutter (for example, a focal-plane shutter) may also be provided.

[0034] The image sensor 12 is formed, for example, on a CMOS substrate, with multiple pixels having photodiodes (photogates), transfer gates (shutter transistors), switching transistors (address transistors), amplification transistors, reset transistors (reset gates), etc., arranged in a two-dimensional manner, and a vertical scanning circuit, a horizontal scanning circuit, and an image signal output circuit are also formed on it.

[0035] The image sensor 12 may be either a primary color system or a complementary color system, and the analog image signal obtained from the image sensor 12 is either a primary color signal or a complementary color signal for each of the RGB colors. Alternatively, the image sensor 12 may be configured without a color filter, so that the analog image signal obtained from the image sensor 12 is a black and white image signal. The analog image signal from the image sensor 12 is sampled and held for each color signal in the analog signal processing unit 13, which is configured as an IC (Integrated Circuit). The amplitude is adjusted by AGC (Automatic Gain Control), and the signal is converted into a digital image signal by A / D (Analog to Digital) conversion. The digital image signal (hereinafter referred to as image data) from the analog signal processing unit 13 is input to the temporary storage unit 26. The image sensor 12 and the analog signal processing unit 13, or even the temporary storage unit 26, may be integrated into a single unit. Furthermore, the frame memory described below, which serves as the temporary storage unit 26, may be provided within the stacked image sensor.

[0036] In this example, the temporary storage unit 26 includes two frame memories 26A and 26B. Image data from the analog signal processing unit 13 is alternately stored in frame memory 26A and frame memory 26B. That is, the temporary storage unit 26 stores two consecutively captured image frames. The image data stored in the temporary storage unit 26 is output sequentially to the digital signal processing unit 20, starting with the previously stored frame. That is, the images are output alternately from frame memory 26A and frame memory 26B to the digital signal processing unit 20 sequentially according to the imaging order. By incorporating frame memories 26A and 26B in this way, it becomes possible to continuously display the live view image without blackout, even during continuous shooting.

[0037] The digital signal processing unit 20 is configured as an image processing processor, for example, by a DSP (Digital Signal Processor). This digital signal processing unit 20 performs various signal processing on the input image data. For example, as part of the camera process, the digital signal processing unit 20 performs preprocessing, syncing, YC generation, etc. Furthermore, the digital signal processing unit 20 performs file formation processing on the image data that has undergone these various processes, such as compression encoding for recording and communication, formatting, and generation and addition of metadata, to generate files for recording and communication. For example, it generates image files in formats such as JPEG, TIFF (Tagged Image File Format), and GIF (Graphics Interchange Format) as still image files. It is also conceivable to generate image files in formats such as MP4, which is used for recording MPEG-4 compliant video and audio. It is also possible to generate the image file as raw image data. Furthermore, the digital signal processing unit 20 performs resolution conversion processing on the image data that has undergone various signal processing, generating image data with reduced resolution for purposes such as live view display.

[0038] The memory section 27 represents the image data buffer memory. This memory section 27 is composed of, for example, D-RAM (Dynamic Random Access Memory). Image data processed by the digital signal processing unit 20 is temporarily stored in the memory unit 27 and then transferred to the display unit 15, the recording control unit 14, or the communication unit 16 at a predetermined timing.

[0039] The recording control unit 14 performs recording and playback on a recording medium, for example, a non-volatile memory. The recording control unit 14 also performs processing to record image files, such as video data and still image data, onto the recording medium. The actual form of the recording control unit 14 can be varied. For example, the recording control unit 14 may be configured as a flash memory and its write / read circuit built into the imaging device 1. Alternatively, the recording control unit 14 may be a card recording and playback unit that performs recording and playback access to a recording medium that can be attached to and removed from the imaging device 1, such as a memory card (portable flash memory, etc.). Furthermore, the recording control unit 14 may be implemented as an HDD (Hard Disk Drive) or the like, built into the imaging device 1.

[0040] The display unit 15 is a display unit that provides various information to the imager, and is, for example, the rear monitor 4 or EVF 5 located on the housing of the imaging device 1, as shown in Figure 1. The display unit 15 performs various displays on the display screen based on instructions from the camera control unit 21. For example, the display unit 15 displays a reconstructed image of the image data read from the recording medium by the recording control unit 14. Furthermore, the display unit 15 is supplied with image data of the captured image that has been resolution-converted for display by the digital signal processing unit 20, and displays accordingly, for example, a live view image. Furthermore, the display unit 15, based on instructions from the camera control unit 21, displays various operation menus, icons, messages, etc., that is, GUI (Graphical User Interface) elements on the screen.

[0041] The communications unit 16 performs data communication and network communication with external devices via wired or wireless connections. For example, it transmits and outputs image data (still image files and video files) and metadata to external information processing devices, display devices, recording devices, playback devices, etc. Furthermore, the communication unit 16, as a network communication unit, can perform various network communications, such as the Internet, home network, and LAN (Local Area Network), and can send and receive various types of data with servers, terminals, etc. on the network.

[0042] The operation unit 17 comprehensively represents the input devices for the user to perform various operations. Specifically, the operation unit 17 represents keys, dials, etc., which serve as various control elements 6 (including dials 6a) provided on the housing of the imaging device 1. Furthermore, the control elements 6 corresponding to the operation unit 17 also include, for example, a touch panel or touchpad provided on the rear monitor 4. The operation unit 17 may also be configured as a receiver for operation signals from a remote controller. The operation unit 17 detects user operations, and a signal corresponding to the input operation is sent to the camera control unit 21.

[0043] The camera control unit 21 is composed of a microcomputer (processing unit) equipped with a CPU (Central Processing Unit). This camera control unit 21 is an imaging control device that controls the operation of the imaging device 1. The memory unit 19 stores information used by the camera control unit 21 for processing. The memory unit 19 shown in the diagram comprehensively represents, for example, ROM (Read Only Memory), RAM (Random Access Memory), flash memory, etc. The memory section 19 may be a memory area built into the microcomputer chip acting as the camera control unit 21, or it may be composed of a separate memory chip. The camera control unit 21 controls the entire imaging device 1 by executing programs stored in the ROM or flash memory of the memory unit 19.

[0044] For example, the camera control unit 21 controls various signal processing operations in the digital signal processing unit 20, as well as imaging and recording operations in response to user operations, and playback operations of recorded image files. Furthermore, the camera control unit 21 performs automatic exposure control, including controlling the operation of the aperture mechanism, controlling the shutter speed of the image sensor 12, and controlling the AGC gain in the analog signal processing unit 13. The camera control unit 21 also controls the drive of the focus lens and zoom lens in response to autofocus control, manual focus operation, zoom operation, etc. The camera control unit 21 also controls the shutter speed and exposure timing of the image sensor 12.

[0045] The camera control unit 21 is also provided with a setting control unit 24 that performs control processing related to the setting of the continuous shooting speed in continuous shooting mode. The setting control unit 24 controls the display of the setting screen for setting the continuous shooting speed on the display unit 15, and performs processing to detect user input from the operation unit 17, i.e., UI (user interface) processing. Furthermore, the setting control unit 24 performs a process to variably set the continuous shooting speed for each continuous shooting mode ("H mode", "M mode", and "L mode") based on the UI processing.

[0046] The camera control unit 21 controls the image recording operation in continuous shooting mode based on the continuous shooting speed setting. Specifically, if one of "H+ mode," "H mode," "M mode," or "L mode" is selected using the dial 6a, the camera control unit 21 controls the imaging operation of the image sensor 12 and the signal processing in the digital signal processing unit 20 so that still image recording is performed according to the continuous shooting mode.

[0047] The RAM in the memory unit 19 is used as a workspace for the CPU of the camera control unit 21 during various data processing operations, and is used for the temporary storage of data, programs, etc. The ROM and flash memory (non-volatile memory) in the memory section 19 are used to store the OS (Operating System) for the CPU to control each part, application programs for various operations, firmware, and various setting information. Various setting information includes communication settings, settings related to imaging operation, and settings related to image processing. Settings related to imaging operation include exposure settings, shutter speed settings, mechanical or electronic shutter curtain speed settings, and mode settings. One of the mode setting pieces of information stored is the current setting for the continuous shooting speed in continuous shooting modes (H+ mode, H mode, M mode, L mode). In addition, the initial setting may be stored in a non-volatile memory area, for example.

[0048] The driver unit 22 includes, for example, a motor driver for the zoom lens drive motor, a motor driver for the focus lens drive motor, and a motor driver for the aperture mechanism motor. These motor drivers apply drive current to the corresponding drivers in response to instructions from the camera control unit 21, causing the movement of the focus lens and zoom lens, the opening and closing of the aperture blades of the aperture mechanism, and other operations.

[0049] Here, I will explain the blackout-free processing during continuous shooting. Live view is displayed before and during the shutter release operation for still image recording. However, there is a phenomenon where the live view image display is interrupted (blackout) after the shutter release. Blackout-free processing is a process that prevents this blackout and interruption of the live view image.

[0050] Let's explain using an example of continuous shooting. For example, during continuous shooting, capture exposure for still image recording is repeated at predetermined intervals. If this capture exposure period is longer than the frame period of the live view image frame rate, one or more inter-frame exposures are performed between capture exposures. For example, exposure operations such as "capture exposure," "inter-frame exposure," "inter-frame exposure," "capture exposure," "inter-frame exposure," "inter-frame exposure," etc., are repeated until continuous shooting ends.

[0051] If the shutter release is performed while the live view image is being exposed, the camera control unit 21 instructs the image sensor 12 to interrupt the exposure of the live view image and start continuous shooting. For example, it instructs the camera control unit 21 to change the readout pixels or resolution in order to perform capture exposure. Then, after the camera control unit 21 has prepared for capture exposure, it starts the capture exposure of the image sensor 12.

[0052] In this sequence of operations, the exposure for the currently running live view image is interrupted at the timing of the shutter release, causing the live view image for that frame to become unavailable and resulting in a blackout. The blackout continues until the capture exposure is performed and the frame of the live view image based on the capture exposure is displayed.

[0053] One method to prevent such blackouts is to avoid interrupting the exposure for the live view image that was being performed at the time of the shutter release. In other words, the exposure for the live view image that was being performed at the time of the shutter release is not interrupted, and the exposure is waited until it is complete. By storing the image data in, for example, frame memory 26A, the live view image for that frame can be displayed. After the exposure of the live view image is complete, preparation for capture exposure is performed, and then the capture exposure is performed. The image data from this capture exposure is stored in frame memory 26B. This allows the display of the live view image to continue using the image data in frame memory 26A until the live view image data based on the capture exposure image data can be generated. This prevents blackouts.

[0054] There are other methods to prevent blackout. For example, if a shutter release is performed while exposure for a live view image is being performed and written to frame memory 26B, the exposure is interrupted, and the latest image stored in frame memory 26A (for example, the image data of the frame immediately preceding the frame in which the exposure was interrupted) is copied to frame memory 26B. Then, the display of the live view image is continued using the image from frame memory 26B. At this time, the image data of the capture exposure is written to frame memory 26A, and after the capture exposure is complete, the live view image based on that captured exposure image data is displayed.

[0055] By using frame memories 26A and 26B in this way, it is possible to prevent interruptions in the live view image during shutter release operations. Especially during continuous shooting, photographers are expected to track the subject while viewing the live view image, so ensuring that the live view image remains uninterrupted through blackout-free processing is extremely useful.

[0056] <2. First Embodiment> The variable setting of the continuous shooting mode as a first embodiment will be described. As described above, the imaging device 1 offers the following continuous shooting modes: "H+ mode," "H mode," "M mode," and "L mode." In this case, H+ mode is a mode with a fixed continuous shooting speed, while H mode, M mode, and L mode have a variable continuous shooting speed.

[0057] Figure 5 shows examples of settings for each of these continuous shooting modes. In each figure, "Hi+", "Hi", "Mid", and "Low" refer to H+ mode, H mode, M mode, and L mode, respectively.

[0058] H+ mode is, for example, a mode where the continuous shooting speed is fixed at 30fps. In H mode, you can choose from four continuous shooting speeds: 20fps, 15fps, 10fps, and 5fps. Similarly, in M ​​mode and L mode, the continuous shooting speed can be selected from four options: 20fps, 15fps, 10fps, and 5fps.

[0059] In other words, for H mode, M mode, and L mode, users can arbitrarily select and set the burst shooting speed to be assigned from the same four options for each mode.

[0060] For example, settings can be configured according to the high-to-low continuous shooting speed relationship between H mode, M mode, and L mode, as follows: H mode = 20fps, M mode = 15fps, L mode = 10fps H mode = 15fps, M mode = 10fps, L mode = 5fps H mode = 20fps, M mode = 10fps, L mode = 5fps H mode = 20fps, M mode = 15fps, L mode = 5fps

[0061] Furthermore, it is also possible to set the continuous shooting speeds in H mode, M mode, and L mode in a reversed order, for example, as follows. H mode = 10fps, M mode = 15fps, L mode = 20fps H mode = 5fps, M mode = 10fps, L mode = 15fps H mode = 5fps, M mode = 10fps, L mode = 20fps H mode = 5fps, M mode = 15fps, L mode = 20fps

[0062] Furthermore, it is possible to set the continuous shooting speed to be the same for all three modes: H mode, M mode, and L mode, as follows. H mode = 20fps, M mode = 20fps, L mode = 20fps H mode = 15fps, M mode = 15fps, L mode = 15fps H mode = 10fps, M mode = 10fps, L mode = 10fps H mode = 5fps, M mode = 5fps, L mode = 5fps

[0063] Furthermore, it is possible to set two of the H, M, and L modes to have the same continuous shooting speed, as follows: H mode = 20fps, M mode = 20fps, L mode = 15fps H mode = 20fps, M mode = 20fps, L mode = 10fps H mode = 20fps, M mode = 20fps, L mode = 5fps H mode = 20fps, M mode = 5fps, L mode = 5fps H mode = 15fps, M mode = 5fps, L mode = 5fps H mode = 10fps, M mode = 5fps, L mode = 5fps Many more combinations are possible to achieve the same continuous shooting speed for both settings.

[0064] In this way, by allowing users to freely adjust the continuous shooting speed in H mode, M mode, and L mode, users can customize H mode, M mode, and L mode to suit their preferences and use cases.

[0065] Figure 6 shows an example of a user interface for making such settings. For example, it is an example of a screen displayed on the display unit 15. Figure 6A shows the drive mode screen 30, which is considered to be a certain level within the menu. Within this drive mode screen 30, there is an item called "Continuous Shooting Speed ​​Customization".

[0066] When the user selects "Customize Continuous Shooting Speed" using the cursor or other means, the screen display proceeds to the continuous shooting mode selection screen 41 shown in Figure 6B. On this continuous shooting mode selection screen 41, the following options are displayed: "Customize High Speed," "Customize Mid Speed," and "Customize Low Speed." These options allow the user to choose whether to customize H mode, M mode, or L mode, respectively.

[0067] For example, if the user selects "Customize Speed ​​Hi," the screen display will proceed to the speed selection screen 42 for H mode, as shown in Figure 6C. On this speed selection screen 42, the options for continuous shooting speed in H mode are displayed as "20fps," "15fps," "10fps," and "5fps." The user can select their desired continuous shooting speed.

[0068] Although not shown in the diagram, if the user selects "Customize Mid Speed" on the continuous shooting mode selection screen 41 in Figure 6B, the screen display will proceed to the speed selection screen 42 for M mode, which has the same options as in Figure 6C. Furthermore, if the user selects "Customize Low Speed" on the continuous shooting mode selection screen 41 in Figure 6B, the screen display will proceed to the speed selection screen 42 for L mode, which has the same options as in Figure 6C. Therefore, in all three modes—H mode, M mode, and L mode—a user interface is provided that allows the user to select the continuous shooting speed from the four options shown in Figure 5.

[0069] Thus, a continuous shooting mode selection screen 41 and a speed selection screen 42 are provided as setting screens 40 for setting the continuous shooting speed, allowing the user to make selections. Item selection on these screens may be performed using cursor operation with a directional pad or similar as the operator 6, or by touch operation using a touch panel, touchpad, etc.

[0070] Figure 7 shows an example of processing by the camera control unit 21 in response to operations using such setting screens 40 (continuous shooting mode selection screen 41 and speed selection screen 42). This is an example of processing by the settings control unit 24 in the camera control unit 21.

[0071] Figure 7 shows the process starting from the state where the drive mode screen 30 shown in Figure 6A is displayed as step S100. When "Customize continuous shooting speed" is selected on the drive mode screen 30, the camera control unit 21 proceeds from step S101 to step S102 and performs the process of displaying the continuous shooting mode selection screen 41 on the display unit 15.

[0072] While the continuous shooting mode selection screen 41 is displayed, the camera control unit 21 monitors user operations in steps S103, S104, S105, and S106. Specifically, it detects whether the following operations are performed: "Customize High Speed", "Customize Mid Speed", "Customize Low Speed", and "Back".

[0073] If the "back" operation is detected, the camera control unit 21 proceeds from step S106 to step S100 and returns to displaying the drive mode screen 30.

[0074] If the camera control unit 21 detects the operation "Customize Speed ​​Hi" on the continuous shooting mode selection screen 41, it proceeds from step S103 to step S111 and displays the H mode speed selection screen 42. At this time, the camera control unit 21 may also indicate the current setting status. For example, if the current continuous shooting speed in H mode is 20fps, the unit may display a checkbox or highlight the "20fps" option, as shown in the example in Figure 6C. The camera control unit 21 then monitors the continuous shooting speed setting change operation in step S112 and the cancellation operation in step S113.

[0075] The user can change the currently selected item (checkbox or highlighted item) among the selected items (each continuous shooting speed) on the speed selection screen 42 displayed in step S111, for example by using the up and down cursor, and then make a confirmation operation. The confirmation operation here refers to operations such as changing the selected item and returning to the previous screen, or pressing the Enter key.

[0076] The operation to confirm the change in the selected item (continuous shooting speed) is called a setting change operation. Once the setting change operation is performed, the camera control unit 21 proceeds from step S112 to step S114 and changes the continuous shooting speed setting for H mode to the newly selected continuous shooting speed. Then it proceeds to step S102 and returns the screen to the continuous shooting mode selection screen 41.

[0077] On the other hand, if the user returns to the previous screen without changing the selected continuous shooting speed on the speed selection screen 42 displayed in step S111, this is considered a cancellation operation, and the camera control unit 21 proceeds from step S113 to step S102, returning the screen to the continuous shooting mode selection screen 41.

[0078] If the camera control unit 21 detects the operation "Customize Mid speed" on the continuous shooting mode selection screen 41 in step S102, it proceeds from step S104 to step S121 and displays the speed selection screen 42 for M mode. At this time, the camera control unit 21 may indicate the current M mode setting status, for example, by displaying or highlighting a checkbox for an item in the selection options. Then, in step S122, the camera control unit 21 monitors the operation to change the continuous shooting speed setting, and in step S123, it monitors the cancellation operation.

[0079] Once the selected item (continuous shooting speed) has been changed, i.e., the setting change operation has been performed, the camera control unit 21 proceeds from step S122 to step S124 and changes the continuous shooting speed setting for M mode to the newly selected continuous shooting speed. Then it proceeds to step S102 and returns the screen to the continuous shooting mode selection screen 41.

[0080] Furthermore, if the user returns to the previous screen without changing the selected continuous shooting speed on the speed selection screen 42 displayed in step S121, this is treated as a cancellation operation, and the camera control unit 21 proceeds from step S123 to step S102, returning the screen to the continuous shooting mode selection screen 41.

[0081] If the camera control unit 21 detects the operation "Customize Speed ​​Low" on the continuous shooting mode selection screen 41 in step S102, it proceeds from step S105 to step S131 and displays the L mode speed selection screen 42. At this time, the camera control unit 21 may indicate the current L mode setting status, for example, by displaying or highlighting a checkbox for an item in the selection options. The camera control unit 21 then monitors the continuous shooting speed setting change operation in step S132 and the cancellation operation in step S133.

[0082] Once the selected item (continuous shooting speed) has been changed, i.e., the setting change operation has been performed, the camera control unit 21 proceeds from step S132 to step S134 and changes the continuous shooting speed setting for L mode to the newly selected continuous shooting speed. Then it proceeds to step S102 and returns the screen to the continuous shooting mode selection screen 41.

[0083] Furthermore, if the user returns to the previous screen without changing the selected continuous shooting speed on the speed selection screen 42 displayed in step S131, this is considered a cancellation operation, and the camera control unit 21 proceeds from step S133 to step S102, returning the screen to the continuous shooting mode selection screen 41.

[0084] The above processing is performed in the camera control unit 21, making it possible to change the continuous shooting speed setting for H mode, M mode, and L mode according to user operation.

[0085] <3. Second Embodiment> As a second embodiment, we will describe an example in which the continuous shooting speed of each continuous shooting mode (H mode, M mode, L mode) can be variably set, within a range in which the relative high-low relationship of the speeds set for each continuous shooting mode does not reverse with respect to the relative high-low relationship presented by dial 6a or the like for each continuous shooting mode.

[0086] As mentioned above, H mode, M mode, and L mode refer to high speed, medium speed, and low speed, respectively. The "H," "M," and "L" markings on dial 6a indicate to the user the relative high and low speeds of each continuous shooting mode. However, as in the first embodiment, if users are allowed to freely select the burst shooting speed, the high and low burst shooting speeds set for each burst shooting mode, and their corresponding "H," "M," and "L" designations, may become inconsistent. This situation is not much of a problem for users who understand the customizations they have made. However, some users may become confused when, for example, turning dial 6a from "L" to "M" results in a slower burst shooting speed. Therefore, it is conceivable to limit the variable setting of the continuous shooting speed for each continuous shooting mode according to the settings of other continuous shooting modes.

[0087] Figures 8, 9, and 10 schematically show the available options when setting the continuous shooting speed in H mode, L mode, and M mode, respectively. As in the example above, in each continuous shooting mode, the continuous shooting speed can be selected from four options: 20fps, 15fps, 10fps, and 5fps, on the speed selection screen 42 as shown in Figure 6B.

[0088] Figure 8 shows the H mode selection options for each case and the M mode continuous shooting speed settings for each case. Assuming you proceed to the speed selection screen 42 to select the H mode continuous shooting speed, there are four possible cases, H1 to H4, depending on the M mode settings.

[0089] Case H1 is when the continuous shooting speed in M ​​mode is set to 20fps. In this case, the only selectable option in H mode is 20fps, and 15fps, 10fps, and 5fps are unavailable. For example, in the speed selection screen 42 in Figure 6C, 15fps, 10fps, and 5fps are grayed out. Note that the black dots (●) in Figures 8, 9, and 10 indicate that the options are grayed out, preventing the user from selecting them. Case H2 is when the continuous shooting speed in M ​​mode is set to 15fps, in which case the selectable options in H mode are 20fps and 15fps. Case H3 is when the continuous shooting speed in M ​​mode is set to 10fps, in which case the selectable options in H mode are 20fps, 15fps, and 10fps. Case H4 is when the continuous shooting speed in M ​​mode is set to 5fps. In this case, the selectable options in H mode are 20fps, 15fps, 10fps, and 5fps.

[0090] Figure 9 shows the L mode settings for each case, including the L mode selection options and the M mode continuous shooting speed settings for each case. Case L1 is when M mode is set to 20fps, in which case the selectable options in H mode are 20fps, 15fps, 10fps, and 5fps. Case L2 is when M mode is set to 15fps, in which case the selectable options in H mode are 15fps, 10fps, and 5fps. Case L3 is when M mode is set to 10fps, in which case the selectable options in H mode are 10fps and 5fps. Case L4 is when M mode is set to 5fps, in which case the only selectable option in H mode is 5fps.

[0091] Figure 10 shows the M mode selection options for each case, as well as the continuous shooting speed settings for H mode and L mode in each case, illustrating the case when setting M mode. Case M1 is when H mode is set to 20fps and L mode is set to 5fps. In this case, the selectable options for M mode are 20fps, 15fps, 10fps, and 5fps. Case M2 is when H mode is set to 15fps and L mode is set to 5fps. In this case, the selectable options for M mode are 15fps, 10fps, and 5fps. Case M3 is when H mode is set to 10fps and L mode is set to 5fps, in which case the selectable options in M ​​mode are 10fps and 5fps. Case M4 is when H mode is set to 5fps and L mode is set to 5fps, in which case the only selectable option in M ​​mode is 5fps. Case M5 is when H mode is set to 20fps and L mode is set to 10fps. In this case, the selectable options in M ​​mode are 20fps, 15fps, and 10fps. Case M6 is when H mode is set to 15fps and L mode is set to 10fps, in which case the selectable options in M ​​mode are 15fps and 10fps. Case M7 is when H mode is set to 10fps and L mode is set to 10fps, in which case the only selectable option in M ​​mode is 10fps. Case M8 is when H mode is set to 20fps and L mode is set to 15fps. In this case, the selectable options in M ​​mode are 20fps and 15fps. Case M9 occurs when both H mode and L mode are set to 15fps, in which case the only selectable option in M ​​mode is 15fps. Case M10 is when both H mode and L mode are set to 20fps, and in this case, the only selectable option in M ​​mode is 20fps.

[0092] As described above, the options available in H mode, M mode, and L mode may be limited depending on the case. In other words, when attempting to customize a particular continuous shooting mode, the available options for that continuous shooting mode are determined by the continuous shooting speed set in the continuous shooting mode adjacent to it in order of highest to lowest continuous shooting speed. Specifically, when selecting H mode as shown in Figure 8, the options are determined according to the setting of M mode; when selecting L mode as shown in Figure 9, the options are determined according to the setting of M mode; and when selecting M mode as shown in Figure 10, the options are determined according to the settings of both H mode and L mode.

[0093] Figure 11 shows an example of the processing of the camera control unit 21 (setting control unit 24) in this second embodiment. Note that the same processing as in Figure 7 is given the same step number and its explanation is omitted. The difference between Figure 11 and Figure 7 is that steps S110, S120, and S130 are performed.

[0094] When the operation "Customize Speed ​​Hi" is detected on the continuous shooting mode selection screen 41 as shown in Figure 6B, the camera control unit 21 proceeds from step S103 to step S110 and determines the currently available continuous shooting speed options for H mode. In other words, it determines the selectable continuous shooting speed based on the M mode setting at that time. This will be one of cases H1 to H4 in Figure 8. Then, in step S111A, the camera control unit 21 displays the speed selection screen 42. At this time, in a screen like the one shown in Figure 6C, unselectable continuous shooting speeds are grayed out, and the cursor is controlled so that it cannot move to those options. Therefore, the user can only select the continuous shooting speeds that are available.

[0095] Furthermore, if the operation "Customize Mid Speed" is detected on the continuous shooting mode selection screen 41 as shown in Figure 6B, the camera control unit 21 proceeds from step S104 to step S120 in Figure 11 and determines the currently available continuous shooting speed options for M mode. In other words, the selectable continuous shooting speed is determined based on the current settings of H mode and L mode. This will be one of cases M1 to M10 in Figure 10. Then, in step S121A, the camera control unit 21 displays the speed selection screen 42. At this time, unselectable continuous shooting speeds are grayed out, and the cursor is controlled so that it cannot move to those options.

[0096] Furthermore, if the operation "Customize Speed ​​Low" is detected on the continuous shooting mode selection screen 41 as shown in Figure 6B, the camera control unit 21 proceeds from step S105 to step S130 in Figure 11 and determines the currently available continuous shooting speed options for L mode. In other words, it determines the selectable continuous shooting speed based on the M mode settings at that time. This will be one of cases L1 to L4 in Figure 9. Then, in step S131A, the camera control unit 21 displays the speed selection screen 42. At this time, unselectable continuous shooting speeds are grayed out, and the cursor is controlled so that it cannot move to those options.

[0097] This process shown in Figure 11 allows the user to customize the continuous shooting speed for each continuous shooting mode, within a range where the relative relationship of the speeds set for each continuous shooting mode does not reverse with respect to the presented relative highs and lows. Furthermore, as can be seen from Figures 8, 9, and 10, it is possible for all or some of the H, M, and L modes to have the same continuous shooting speed. This satisfies the demands of users who want to have continuous shooting modes with the same continuous shooting speed.

[0098] A modified example of the second embodiment is given below. One possible method to allow customization of the relative speeds set for each burst shooting mode, within a range that does not reverse the relative highs and lows presented, is to fix the burst shooting speed options as follows: H-mode options: 20fps, 15fps M mode options: 15fps, 10fps L mode options: 10fps, 5fps Let's assume that.

[0099] In this way, no matter what selection the user makes in each burst shooting mode, the relationship between high and low burst shooting speeds will not be reversed.

[0100] <4. Third Embodiment> As a third embodiment, we will describe an example that allows the settings to be initialized. For example, the speed selection screen 42 shown in Figure 6B will be shown as the speed selection screen 42A in Figure 12. In other words, in addition to the selection of H mode, M mode, and L mode, a "return to default" option will be added.

[0101] The camera control unit 21 then performs the processing shown in Figure 13. Note that the same steps as in Figure 7 are given the same step numbers and their explanations are omitted. The difference between Figure 13 and Figure 7 is that steps S140 and S141 are performed.

[0102] If the camera control unit 21 detects an initialization operation, that is, an operation to "return to default," on the continuous shooting mode selection screen 41A as shown in Figure 12, the camera control unit 21 proceeds from step S140 to step S141 and performs the process of restoring the H mode, M mode, and L mode settings to their default settings. The camera control unit 21 stores default settings for H mode, M mode, and L mode, for example, as factory initial settings, in the memory unit 19, such as 20fps, 10fps, and 5fps. Then, in step S141, these default settings are read out and set as the current settings.

[0103] Providing such a feature is useful when users want to revert to the initial state after making customizations. In particular, when a high degree of customization is allowed, as in the first embodiment, the relationship between the high and low burst shooting speeds set for each burst shooting mode and their "H," "M," and "L" designations may be reversed. This is useful when a user wishes to reverse the high and low relationship between the burst shooting speeds of H mode, M mode, and L mode after it has been reversed.

[0104] Alternatively, you could implement a process that automatically reverts to the default settings after a certain period of time has elapsed without any user intervention. Furthermore, by customizing the first embodiment, if the relationship between the display of each continuous shooting mode and the high / low continuous shooting speed is reversed, the device may automatically revert to the default settings after a certain period of time (e.g., one day, one week, one month, etc.). This can prevent confusion during operation, for example, if the user forgets the previous settings or if another user is using the device.

[0105] <5.UI example> The following describes various examples of setting screens 40 (continuous shooting mode selection screen 41, speed selection screen 42) that can be used in the first, second, and third embodiments described above. Each of the following examples is implemented by display control by the camera control unit 21 (setting control unit 24).

[0106] Figure 14 shows an example of a continuous shooting mode selection screen 41B, which replaces the continuous shooting mode selection screen 41 in Figure 6B. In addition to the continuous shooting mode options, this continuous shooting mode selection screen 41B also displays the current setting value 43 for each continuous shooting mode. In the example shown in the figure, the user is shown that the current settings are 30fsp for H+ mode, 20fsp for H mode, 15fsp for M mode, and 10fsp for L mode. By allowing users to compare and check the current settings for each burst shooting mode, it becomes easier for them to customize their settings as they wish. It also makes it easier for them to recognize which burst shooting mode should be changed.

[0107] Figure 15 shows a speed selection screen 42A, which replaces the speed selection screen 42 in Figure 6C. This speed selection screen 42A allows the user to select the continuous shooting speed based on the number of continuous shots taken per unit time (e.g., 1 second). For example, the options on the screen can be scrolled vertically to select any number of shots, for example, from 20 to 1, in increments of 1. For example, by allowing users to select each of the H mode, M mode, and L mode in increments of one image, the degree of freedom in user settings is greatly increased.

[0108] Figure 16 shows a speed selection screen 42B, which replaces the speed selection screen 42 in Figure 6C. In this speed selection screen 42A, the continuous shooting speed can be selected in 1 fsp increments (i.e., in 1-frame increments, just like in Figure 15) by changing the setting on the gauge 44 using cursor operation (for example, left and right movement of the directional keys). The scale on the gauge 44 scrolls left and right, allowing arbitrary selection in 1-frame increments, for example, between 20 frames and 1 frame, beyond the range displayed on the screen as shown in the figure. The value specified in gauge 44 is displayed prominently as the selected value 45. Using gauge 44 makes it easier for users to intuitively understand the adjustable range. Furthermore, the current setting value of 43 is displayed for each continuous shooting mode. This allows the user to select the currently selected continuous shooting mode while checking the settings of other continuous shooting modes.

[0109] Figure 17 shows an example of a continuous shooting mode selection screen 41C, which replaces the continuous shooting mode selection screen 41 in Figure 6B. This example allows the continuous shooting speed setting to be changed in H+ mode as well, and allows H+ mode, H mode, M mode, and L mode to be set on a single screen. The screen displays gauges 44H+ for H+ mode, 44H for H mode, 44M for M mode, and 44L for L mode, allowing the user to select the continuous shooting speed for each continuous shooting mode in 1fsp increments. The values ​​specified for each gauge (44H+, 44H, 44M, 44L) are displayed in large font as the selected values ​​(45H+, 45H, 45M, 45L). For example, the user selects a gauge using vertical cursor movements (e.g., using the up and down directions on the directional pad) and selects a value on the gauge using horizontal cursor movements (e.g., using the left and right directions on the directional pad). Each gauge, 44H+, 44H, 44M, and 44L, has a scale that scrolls horizontally, allowing selection within a range, for example, from "0" to "30". This example makes it easier for users to select the appropriate burst shooting speed while considering the speed relationships between each burst shooting mode on a single screen.

[0110] Figure 18, like Figure 17, is an example where the continuous shooting speed for each continuous shooting mode can be selected within a single screen using each gauge (44H+, 44H, 44M, 44L), but it is an example where the selection range is limited. In the illustrated state, in H+ mode, values ​​(scale marks) from "1" to "9" are grayed out; in H mode, values ​​from "1" to "4" are grayed out; in M ​​mode, values ​​from "1" to "4" and "11" to "15" are grayed out; and in L mode, values ​​from "6" to "15" are grayed out. The cursor cannot be moved to the grayed-out scale marks. For example, by doing this, it is possible to prevent the relationship between the notation of each continuous shooting mode and the high or low continuous shooting speed from being reversed, as described in the second embodiment. Furthermore, the range of the scale that is grayed out is changed according to the setting values ​​of the continuous shooting modes, where the height relationship is adjacent, as described in the second embodiment. Alternatively, as described in the modified version of the second embodiment, the configurable range may be fixed for each continuous shooting mode.

[0111] <6. Summary and Variations> According to the imaging device 1 of the above embodiment, the following effects can be obtained.

[0112] The imaging device 1 of this embodiment has a camera control unit 21 (setting control unit 24) that has a selection of continuous shooting speeds, including a continuous shooting speed that is the same as that of other continuous shooting modes, for all or some of the multiple continuous shooting modes, and sets the continuous shooting speed for each continuous shooting mode from the selection according to the operation. For example, in the first to third embodiments, the continuous shooting modes selectable by dial 6a include, for example, H+ mode, H mode, M mode, and L mode. Furthermore, the user can select and set the continuous shooting speed for H mode, M mode, and L mode. This allows users to select different continuous shooting modes and speeds depending on their ease of use and use case. Therefore, it provides an extremely convenient function for photographers who require high-quality images to suit various situations. In particular, in the first and second embodiments, it is possible to set the H mode, M mode, and L mode to the same continuous shooting speed. Depending on the user or use case, this has the effect of preventing images from being captured at an undesirable continuous shooting speed due to accidental switching of the continuous shooting speed.

[0113] Furthermore, as in the modified version of the second embodiment, the same continuous shooting speed can be set for both H mode and M mode, and the same continuous shooting speed can be set for both M mode and L mode. Even if at least some of the continuous shooting modes in which the continuous shooting speed can be set to the same speed, a user-friendly experience can be provided. For example, for users who want three levels of variable speed for continuous shooting, it is useful that M mode and L mode can be set to the same continuous shooting speed. Also, for users who frequently switch between H+ mode and H mode, being able to set H mode and M mode to the same continuous shooting speed is useful as a way to prevent accidental operation, as even if the dial 6a is accidentally turned to M mode, the continuous shooting speed will be the same as in H mode.

[0114] Furthermore, when providing four continuous shooting modes as in the embodiment, the H+ mode may also be made variable in setting the continuous shooting speed, as exemplified in Figures 17 and 18. Alternatively, instead of providing an H+ mode, three continuous shooting modes may be provided: H mode, M mode, and L mode, all of which allow for variable continuous shooting speed settings. Or, two continuous shooting modes may be provided: H mode and L mode, both of which allow for variable continuous shooting speed settings. In other words, it would be good to allow variable settings for the continuous shooting speed in all continuous shooting modes. Of course, it's also possible to have five or more continuous shooting modes.

[0115] In each embodiment, the multiple continuous shooting modes, in which the continuous shooting speed can be selected, have the same selection of continuous shooting speeds. For example, in the first embodiment, three continuous shooting modes are provided: H mode, M mode, and L mode, all of which offer a choice of "20fps," "15fps," "10fps," and "5fps." In other words, H mode, M mode, and L mode allow the user to freely set the continuous shooting speed from the same set of options. For highly skilled photographers, it is sometimes desirable to be able to customize the settings to suit their own needs, taking into account special use cases and operating habits. Therefore, providing the same set of options for the three continuous shooting modes and expanding the user's freedom is useful.

[0116] In this embodiment, as can be seen from the notation on dial 6a in Figure 2, the multiple continuous shooting modes, which allow selection of continuous shooting speeds, are continuous shooting modes that present the relative highs and lows of each continuous shooting speed. In other words, three continuous shooting modes are provided—H mode, M mode, and L mode—which allow the user to select the continuous shooting speed. These modes are displayed on dial 6a, for example, as "H," "M," and "L." By indicating the high and low continuous shooting speeds in this way, users can more easily understand the relationship between the continuous shooting speeds in each mode, improving usability.

[0117] In the second embodiment, an example was given in which the continuous shooting speed of each continuous shooting mode can be variably set, within a range in which the relative relationship of the speeds set for each continuous shooting mode does not reverse with respect to the relative highs and lows presented above. For example, three continuous shooting modes are provided, H mode, M mode, and L mode, where the continuous shooting speed can be selected. M mode cannot be faster than H mode, L mode cannot be faster than M mode, H mode cannot be slower than M mode, and M mode cannot be slower than L7 mode. By maintaining the high-low relationship of the continuous shooting mode display in this way, users can always rely on the "H," "M," and "L" displays to operate dial 6a, thereby improving usability.

[0118] In the second embodiment, the camera control unit 21 performs control on the continuous shooting speed setting screen 40 (speed selection screen 42) for the continuous shooting mode, determining and displaying the selectable continuous shooting speeds according to the continuous shooting speed set in the continuous shooting mode adjacent to that continuous shooting mode in order of increasing continuous shooting speed (see steps S110, S120, S130 in Figure 11). This means that, for example, the selection range for H mode and L mode changes depending on the setting of M mode. Similarly, the selection range for M mode changes depending on the setting of H mode, and the selection range for M mode changes depending on the setting of L mode. Therefore, the user can select a burst shooting speed for a particular burst shooting mode within a range that maintains the relative height of the burst shooting mode display, depending on the current setting of each burst shooting mode.

[0119] In the second embodiment, the camera control unit 21 performs control to display, on the continuous shooting speed setting screen for the continuous shooting mode, any continuous shooting speed that it has determined cannot be selected in that continuous shooting mode as unavailable (see steps S111, S121, and S131 in Figure 11). For example, it displays the option in a grayed-out state. This allows users to consciously select a burst shooting speed that is otherwise unavailable in order to maintain the high / low relationship between shots.

[0120] In the third embodiment, the camera control unit 21 performs a process to reset the continuous shooting speed settings for multiple continuous shooting modes, in which continuous shooting speeds can be selected, to their initial state in response to a setting initialization operation (see steps S140 and S141 in Figure 13). Allowing users to freely change the continuous shooting speed in each continuous shooting mode may disrupt the relative speed relationships between H mode, M mode, and L mode. Furthermore, changes in use cases after customization may necessitate reverting to the default settings. To address these situations, enabling an initialization operation is preferable.

[0121] In this embodiment, the camera control unit 21 is shown as an example of controlling the camera to display the current setting value of the continuous shooting speed for each continuous shooting mode on the continuous shooting speed setting screen 40. For example, this is the current setting value 43 on the continuous shooting mode selection screen 41B in Figure 14, and the current setting value 43 on the speed selection screen 42B in Figure 16. By displaying the current setting of 43 for each burst shooting mode, users can check the current settings for each burst shooting mode and change the burst shooting speed for each mode.

[0122] In this embodiment, the camera control unit 21 is shown as an example of a control that presents the continuous shooting speed options as a value indicating the number of still images recorded per unit time. For example, in a setting screen for the user to set a variable continuous shooting speed, the continuous shooting speed is displayed by showing the fps or the number of still images (see Figures 6C and 15). This allows users to set the continuous shooting speed while clearly understanding the number of still images captured and recorded in each continuous shooting mode.

[0123] In this embodiment, the camera control unit 21 performs control that allows the user to select the continuous shooting speed by specifying the number of still images to be recorded per unit time. For example, a user interface is provided that allows the user to specify the number of still images to be recorded per second in increments of one (see Figures 15 and 16). This allows users to specify the continuous shooting speed in each continuous shooting mode by the number of still images (frames) recorded per second. Therefore, users can set the continuous shooting speed with greater flexibility.

[0124] In this embodiment, the camera control unit 21 performs control that allows the user to select the continuous shooting speed by specifying the number of still images to be recorded per unit time using a cursor on the gauge 44 (see Figures 16, 17, and 18). According to user interface examples such as Figure 16, the user can specify the continuous shooting speed by the number of still images (frames) recorded per second on the gauge 44. The gauge 44 makes it easy for the user to intuitively understand the setting. In the example shown in Figure 16, the current setting value of 43 is also displayed, allowing the user to adjust the settings while checking the relative relationship of the continuous shooting speeds for each continuous shooting mode.

[0125] In this embodiment, the camera control unit 21 performs control to display a screen that allows the continuous shooting speed settings for multiple continuous shooting modes to be adjusted on a single screen (see Figures 17 and 18). This UI example makes it easy for users to manage the burst shooting speed settings for each burst shooting mode while being aware of their interrelationships.

[0126] In the embodiment, an example was given in which an operator is provided to select multiple continuous shooting modes and imaging operation modes, including a single-shot mode. Specifically, dial 6a allows switching between single-shot mode and multiple continuous shooting modes (e.g., H+ mode, H mode, M mode, L mode). This makes it easy to switch between recording still images with single shots and recording continuous shots at various shooting speeds. Alternatively, the continuous shooting mode could be switched using a touch panel, lever, or other type of control instead of a dial.

[0127] In one embodiment, an example was given in which, as part of multiple continuous shooting modes, a continuous shooting mode is provided in which a continuous shooting speed that cannot be set in multiple continuous shooting modes in which the continuous shooting speed can be selected is fixed. For example, in the first, second, and third embodiments, the H+ mode is a mode with a fixed continuous shooting speed, and the continuous shooting speed cannot be set in any of the H, M, or L modes. By providing such an H+ mode, the continuous shooting speed switching function can be maintained even when, for example, the H, M, and L modes are set to the same continuous shooting speed.

[0128] In this embodiment, the modes were named "H+ mode," "H mode," "M mode," and "L mode," which represent ultra-high speed, light speed, medium speed, and low speed, respectively. However, mode names that do not indicate (or are difficult to recognize) relative speed relationships may also be used. For example, names such as "Speed ​​A mode," "Speed ​​B mode," and "Speed ​​C mode" may be used, making it difficult for the user to recognize the speed relationship.

[0129] In this embodiment, an imaging device 1 equipped with a temporary storage unit 26 (frame memory 26A, 26B) that enables blackout-free operation was used as an example. However, the technology of this disclosure can also be applied to an imaging device 1 that is not equipped with a temporary storage unit 26.

[0130] The program of this embodiment is a program that causes a processing unit, such as a CPU, to perform the above-mentioned control of setting the continuous shooting speed. In other words, the program of this embodiment allows the user to select from multiple continuous shooting speeds, including a continuous shooting speed that is the same as that of other continuous shooting modes, for all or some of the multiple continuous shooting modes, and causes the processing unit to execute control to set the continuous shooting speed of the continuous shooting mode according to the user's operation. With such a program, the camera control unit 21 described above can be implemented using a processing unit such as a microcomputer.

[0131] These programs can be pre-recorded on storage media such as HDDs (hard disk drives) built into computer devices, or on ROM (remote memory) within microcomputers with CPUs. Alternatively, programs can be temporarily or permanently stored (recorded) on removable storage media such as flexible disks, CD-ROMs (Compact Disc Read Only Memory), MO (Magneto Optical) disks, DVDs (Digital Versatile Discs), Blu-ray Discs (registered trademark), magnetic disks, semiconductor memory, and memory cards. Such removable storage media can be provided as so-called packaged software. In addition to installing such programs from removable storage media to personal computers, they can also be downloaded from download sites via networks such as LANs (Local Area Networks) and the Internet.

[0132] By the way, in the embodiment, the explanation was given using an example where multiple "frame rate modes" were assumed to be multiple "continuous shooting modes". The technology described in this embodiment can be applied to various frame rate modes. For example, multiple LV image frame rate modes could be provided, each allowing the frame rate of the live view image to be set individually. Furthermore, for each LV image frame rate mode, the frame rate of the live view image could be set according to the selection made from the available options. Furthermore, multiple video frame rate modes are provided, each allowing the user to set their own frame rate for video capture. For each video frame rate mode, the frame rate of the captured video may be set according to the user's selection from the available options.
