  Hereinafter, an embodiment in which an imaging apparatus of the present invention is applied to a digital camera will be described. As shown in FIGS. 1A and 1B, the external configuration of the digital camera 1 includes a photographing lens 2, a self-timer lamp 3, an optical viewfinder window 4, a microphone on the front surface of a substantially rectangular thin plate body. The unit 5, the strobe light emitting unit 6, and the rubber grip 7 are disposed, and a power key 8 and a shutter key 9 are disposed on the right end side (for the user) of the upper surface.

  The rubber grip 7 is a rubber disposed so that the middle finger, ring finger, and little finger of the right hand can securely grip the housing when the user grips the digital camera 1 with the right hand from the right side of the housing at the time of shooting. It is a strip-shaped protrusion made of metal.

  The power key 8 is a key operated every time the power is turned on / off, and the shutter key 9 is a key for determining the photographing timing in the recording mode.

  Further, a mode switch (SW) 10, a speaker unit 11, a menu key 12, a cross key 13, a set key 14, an optical viewfinder 15, a strobe charge lamp 16, and a display unit 17 are arranged on the back of the digital camera 1. ing.

  The mode switch 10 is constituted by a slide key switch, for example, and switches between a recording mode “R” and a reproduction mode “P” which are basic modes.

  The menu key 12 is operated when selecting various menu items.

  The cross key 13 is integrally formed with keys for moving the cursor in the up, down, left, and right directions, and is operated when moving menu items and the like displayed on the display unit 17.

  The set key 14 is disposed at the center position of the cross key 13 and is operated to set the contents of the menu item selected at that time.

  The strobe charge lamp 16 is an LED lamp disposed in the vicinity of the optical viewfinder 15. When the user of the digital camera 1 is looking through the optical viewfinder 15 and when viewing the display unit 17. In any case, it is possible to make the user visually recognize the charge state of the strobe.

  The display unit 17 is constituted by a color liquid crystal panel with a backlight, for example, and displays a through image on the monitor as an electronic viewfinder in the recording mode, and reproduces and displays the selected image and the like in the reproduction mode.

  Although not shown, the digital camera 1 has a memory card slot for attaching / detaching a memory card used as a recording medium, a serial interface connector for connecting to an external personal computer, etc., for example, USB (Universal). (Serial Bus) connector and the like are provided.

  Next, the electronic circuit configuration of the digital camera 1 will be described with reference to FIG. In the recording mode which is the first basic mode of the digital camera 1, the photographing light of the lens optical system 22 constituting the photographing lens 2 whose focus position and aperture position are moved by driving the motor (M) 21. A CCD 23, which is an image sensor disposed behind the axis, is scanned and driven by a timing generator (TG) 24 and a vertical driver 25, and outputs a photoelectric conversion output corresponding to a light image formed at fixed intervals for one screen. .

  The photoelectric conversion output is appropriately gain-adjusted for each primary color component of RGB in the state of an analog value signal, then sampled and held by a sample hold circuit (S / H) 26, and digital data by an A / D converter 27 The color process circuit 28 performs color process processing including pixel interpolation processing and γ correction processing in the color process circuit 28 to generate a digital luminance signal Y and color difference signals Cb, Cr, which are sent to a DMA (Direct Memory Access) controller 29. Is output.

  The DMA controller 29 outputs the luminance signal Y and the color difference signals Cb and Cr output from the color process circuit 28 by using the composite synchronization signal, the memory write enable signal, and the clock signal from the color process circuit 28 once. The data is written in a buffer in the DMA controller 29, and DMA transfer is performed to the DRAM 31 used as a buffer memory via the DRAM interface (I / F) 30.

  The control unit 32 includes a CPU that executes an operation program, a ROM that fixedly stores the operation program executed by the CPU, a RAM that is used as a work memory, and the like. After the DMA transfer of the luminance and chrominance signals to the DRAM 31 is completed, the luminance and chrominance signals are read from the DRAM 31 via the DRAM interface 30 and written to the VRAM 34 via the VRAM controller 33.

  The digital video encoder 35 periodically reads out the luminance and color difference signals from the VRAM 34 via the VRAM controller 33, generates a video signal based on these data, and outputs the video signal to the display unit 17.

  As described above, the display unit 17 functions as a monitor display unit (electronic finder) in the recording mode. By performing display based on the video signal from the digital video encoder 35, the VRAM controller 33 at that time. The image based on the image information captured from is displayed in real time.

  Here, the image displayed in real time is also referred to as a through image hereinafter.

  As described above, when the shutter key 9 is operated at a timing when it is desired to take a still image while the current image is displayed on the display unit 17 in real time as a monitor image, a trigger signal is generated.

  In response to the trigger signal, the control unit 32 immediately transfers the luminance and color difference signals for one screen captured from the CCD 23 at that time to the DRAM 31 immediately after the DMA transfer to the DRAM 31 from the CCD 23 to the DRAM 31. Stop the route.

  Then, the control unit 32 executes a captured image evaluation process, which will be described later in detail, based on the luminance and color difference signals for one frame written in the DRAM 31 at this time, and enters the record storage state of the captured image. Transition.

  In this record storage state, the control unit 32 outputs the luminance and color difference signals for one frame written in the DRAM 31 through the DRAM interface 30 for each of Y, Cb, and Cr components of 8 pixels × A unit called a basic block of 8 horizontal pixels is read out and written into a JPEG (Joint Photographic Coding Experts Group) circuit 36, and this JPEG circuit 36 uses ADCT (Adaptive Discrete Cosine Transform: Adaptive Discrete Cosine Transform), entropy coding, Data compression processing such as Huffman coding is performed.

  The code data obtained in this way is read out from the JPEG circuit 36 as a data file of one image, and is fixed to the digital camera 1 or the memory card 37 that is detachably mounted as a recording medium of the digital camera 1. On the basis of the evaluation result by the photographed image evaluation process, an error attribute is associated and written as needed in any one of the built-in memories 38.

  At this time, the control unit 32 detects the recordable remaining capacity of the memory in which the image data has been written, and when the detected recordable remaining capacity is smaller than a predetermined capacity threshold, the details are as follows. A captured image deletion process to be described later is executed.

  The control unit 32 is accompanied by the compression processing of luminance and color difference signals for one frame and the completion of writing of all the compressed data to the memory card 37 or the built-in memory 38, or the termination of the photographed image deletion processing. Activates the path from the CCD 23 to the DRAM 31 again.

  Here, unlike the other operation keys, the shutter key 9 has a plurality of strokes, for example, a stroke amount sensor or a multi-stage switch that can detect a stroke amount of 5 steps, and the stroke amount for the pressing operation is also set. Detected and a detection signal is sent directly to the control unit 32.

  Further, a key input unit 39, an audio processing unit 40, a USB interface (I / F) 41, and a strobe driving unit 42 are connected to the control unit 32.

  The key input unit 39 includes the power key 8, the mode switch 10, the menu key 12, the cross key 13, the set key 14, and the like, excluding the shutter key 9 described above. The corresponding signal is sent directly to the control unit 32.

  The audio processing unit 40 includes a sound source circuit such as a PCM sound source, digitizes the audio signal input from the microphone unit (MIC) 5 when recording audio, and performs a predetermined data file format such as MP3 (MPEG-1 audio layer). 3) Data compression is performed according to the standard to create an audio data file and send it to the memory card 37 or the built-in memory 38, while audio data sent from the memory card 37 or the built-in memory 38 when playing back sound The file is uncompressed and converted into an analog signal, and the speaker unit (SP) 11 is driven to emit a loud sound.

  The USB interface 41 performs communication control when image data and other data are transmitted / received to / from another information terminal device such as a personal computer connected by wire via a USB connector.

  The strobe driving unit 42 charges a strobe large capacity capacitor (not shown) at the time of still image shooting and then drives the strobe light emitting unit 6 to flash based on the control from the control unit 32.

  However, at the time of shooting a moving image instead of a still image, while the shutter key 9 is continuously operated, the memory card 37 or the still image data file in which the above-described still image data is compressed by the JPEG circuit 36 is used. Recording to the built-in memory 38 is performed continuously in time, and when a predetermined time limit, for example, 30 seconds elapses, the series of still image data files are batched. Then re-set as a motion JPEG data file.

  That is, the general operation of the digital camera 1 in the recording mode, which is the first basic mode, is as shown in the flowchart of FIG. Is operated (SA1), an image is captured, and the captured image captured at this time is determined as a captured image to be recorded in the memory card 37 or the built-in memory 38 (SA2). Then, the photographed image evaluation process is performed on the photographed image (SA3), and the data compression process is performed (SA4).

  When the captured image is evaluated as an error image, which will be described later in detail by the captured image evaluation process (SA5), an error attribute corresponding to the type of the error image is generated by the image data generated by the data compression process (image Error attribute addition processing associated with the data file) is performed (SA6), and image data (captured image) associated with the error attribute is recorded in the memory card 37 or the built-in memory 38 (SA7).

  Then, the recordable remaining capacity of the memory in which the photographed image is recorded is detected (SA8), and when the detected recordable remaining capacity is smaller than a predetermined capacity threshold (SA9), the photographed image deletion process is performed. Is executed (SA10).

  In the playback mode, which is the second basic mode of the digital camera 1, the control unit 32 selectively reads out the image data recorded in the memory card 37 or the built-in memory 38, and the JPEG circuit 36 uses the recording mode. In some cases, the compressed image data is decompressed by a procedure that is completely opposite to the procedure of data compression, the decompressed image data is retained in the DRAM 31 via the DRAM interface 30, and the content retained in the DRAM 31 is stored in the VRAM. The image data is stored in the VRAM 34 via the controller 33, and image data is periodically read out from the VRAM 34 to generate a video signal, which is reproduced and output as a photographed image on the display unit 17.

  When the selected image data is not a still image but a moving image, the playback of the individual still image data constituting the selected moving image file is executed continuously in time, and the playback of all the still image data is finished. At that time, the image is reproduced and displayed using only the still image data located at the head until the next reproduction instruction is given.

  When the error attribute is associated with image data (captured image) recorded in the memory card 37 or the built-in memory 38, details corresponding to the error attribute prepared in advance will be described later. For example, as shown in FIG. 4, 50 is displayed at one end on the photographed image 51 reproduced and output on the display unit 17.

  Here, the display position of the error tag 50 is not limited to one end on the captured image 51, but a position where it can be recognized that the error tag 50 is displayed corresponding to the captured image 51. As long as it is displayed.

  In other words, the general operation of the digital camera 1 in the playback mode, which is the second basic mode, is performed, for example, when the cross key 13 is operated (SB1) as shown in the flowchart of FIG. In response to the above operation, predetermined image data recorded in the memory card 37 or the built-in memory 38 is selected (SB2). Then, the expansion processing is performed on the selected image data as described above (SB3), and the selected image data is displayed on the display unit 17 as a captured image (SB4). At this time, if the selected image data is recorded in association with the error attribute (SB5), an error tag corresponding to the error attribute is displayed on the display unit 17 so as to correspond to the captured image. (SB6). Further, at this time, for example, when the set key 14 is operated as a deletion determination key (SB7), the image data is deleted from the memory in which the image data corresponding to the displayed captured image is recorded. (SB8), the process returns to step SB2.

  Hereinafter, the captured image evaluation process (step SA3) and the error attribute addition process (steps SA5 and SA6) performed by the control unit 32 will be described. The photographed image evaluation process is a process for evaluating the image quality of a photographed image recorded as image data in the memory card 37 or the built-in memory 38. As the evaluation items, for example, the degree of exposure (over / under) of the photographed image, the degree of camera shake of the photographed image, the degree of blur of the photographed image, and the degree of breakage of the photographed image are prepared.

  For example, the exposure degree of the photographed image can be evaluated by performing a predetermined calculation from the dynamic range of the density of the photographed image and the minimum density point to determine whether the exposure degree is appropriate. The dynamic range refers to the difference between the maximum density point and the minimum density point of the density. When the dynamic range is less than the predetermined threshold value, it can be evaluated that the minimum density point is less than the predetermined threshold value. If the maximum density point is equal to or greater than a predetermined threshold value, it can be evaluated as overexposed.

  The degree of camera shake can be evaluated by obtaining the edge amount of the entire captured image. Specifically, a high frequency component is extracted from the photographed image, and the extracted high frequency component is binarized with a predetermined threshold to detect an edge pixel, and the detected number of edge pixels is derived as an edge amount. Then, it can be evaluated that camera shake occurs when the edge amount is smaller than a predetermined threshold value.

  The degree of defocus of the captured image can be evaluated by detecting the edge amount of the image located near the center of the captured image region, for example. Contrary to the above, the background image can be defocused by detecting the edge amount of an image located in the periphery of the captured image region.

  The error attribute adding process is a process of generating an error attribute corresponding to each evaluation result based on the evaluation result as described above by the photographed image evaluation process and associating it with the evaluation target image data.

  Specifically, when the photographed image evaluation process evaluates that the degree of exposure of the photographed image is inappropriate, an error attribute indicating that the degree of exposure of the photographed image is inappropriate is also displayed on the photographed image. If it is evaluated that a camera shake has occurred in the shot image, and if it is evaluated that the shot image is out of focus, the shot image will be out of focus. Error attribute indicating that the image has been interrupted, and further, if it is evaluated that the image has been interrupted, an error attribute indicating that the image has been interrupted is generated. As described above, the image data is associated with the image data compressed and converted based on the evaluation target image.

  That is, in the photographed image evaluation process and the error attribute addition process, an evaluation is made as to whether or not the image is an error image that has some error in the image quality of the photographed image recorded in the memory card 37 or the built-in memory 38. When the discrimination target image is an error image, an error attribute is generated so that it can be identified that it is an error image, and so that an existing error type can be identified. Thus, the error attribute is associated with the discrimination target image.

  The error attribute may be added as header information of the image data, or may be generated as management data separately. In any case, it is sufficient that the configuration is associated with the discrimination target image.

  Next, the captured image deletion process in step SA10 will be described. The captured image deletion process is performed when predetermined remaining image data (captured image) is recorded in the memory card 37 or the built-in memory 38 when the remaining recordable capacity of the memory card 37 or the built-in memory 38 is smaller than a predetermined capacity threshold. Is deleted and the recordable remaining capacity is secured. As shown in FIG. 6, the display order is shown in the image data (captured image) recorded in the memory based on the priority order table described later for details. Display order setting process (SC1) for setting the image, and a photographed image deletion screen in which predetermined photographed images are sequentially displayed in accordance with the display order set in the display order setting process. It comprises a deletion execution process (SC2) for deleting a photographed image for which an operation has been instructed from the memory.

  For example, as shown in FIG. 7, the priority order table is a table in which priorities are set between the error attributes. When a captured image is displayed on the captured image deletion screen, the memory is displayed in a predetermined display order. It is a table that is referred to in the display order setting process so that the photographed image recorded in is displayed.

  For example, a captured image recorded in association with an error attribute having a higher priority in the priority order table is displayed first on the captured image deletion screen.

  In addition, the priority order table is set and stored in advance by a priority order setting process executed as an attached mode of the digital camera, for example, before the captured image deletion process is executed.

  More specifically, based on the flowchart of FIG. 8, for example, when a priority setting mode for executing the priority setting process is selected by a user operation on the digital camera, the control unit 32 displays the display. For example, the priority setting screen as shown in FIG. 9 is displayed on the unit 17 (SD1).

  Error priority selection icons corresponding to the various error attributes are displayed on the priority order setting screen. For example, an “exposure” icon 61 corresponding to an error attribute indicating that the exposure level of the photographed image is inappropriate, or a “camera shake” icon 62 corresponding to an error attribute indicating that camera shake is occurring in the captured image, A “defocus” icon 63 corresponding to an error attribute indicating that the photographed image is out of focus and a “discontinuity” icon 64 corresponding to an error attribute indicating that the image is interrupted in the photographed image are displayed. Is done.

  In the priority setting screen, the currently selected error attribute selection icon is displayed on the currently selected error attribute selection icon so that the currently selected error attribute selection icon can be identified among the plurality of displayed error attribute selection icons. A selection frame 60 is displayed. The selection frame 60 can be moved as a selection frame movement key onto a desired error attribute selection icon, for example, by operating the cross key 13 (SD2, SD3).

  As the error attribute selection icon determination key, for example, when the set key 14 is operated (SD4), the corresponding error attribute is selected and set, and the error attribute selection icon is displayed, for example, in black characters on a white background. Is switched to black white character display to inform the user that the error attribute corresponding to the error attribute selection icon has been selected and set. When the error attribute selection icon for which the error attribute is selected and set is selected again and the set key 14 is operated, the corresponding error attribute selection setting is canceled and the error attribute selection icon is displayed on the black background. The white character display is switched to the white black character display, and the user is informed that the error attribute corresponding to the error attribute selection icon has been released from the selection setting (SD5, SD6, SD7, SD8, SD9).

  At this time, as shown in FIG. 7, the control unit 32 determines that the priority order of the selected and set error attributes is between the selected and set error attributes. The priority order between the error attributes is set so that the priority order is higher than the priority order of the error attributes not selected and set (SD10).

  Further, when a plurality of error attributes are selected and set (SD11), for example, according to the order of selection and setting, the priority order of the error attribute that is selected and set first is higher than the priority order of the error attribute that is selected and set later. A priority order is set between the selected and set error attributes so that the priority order is high (SD12).

  Then, when the selection frame 60 is operated on the “end” icon 69 and, for example, the set key 14 is operated as an end determination key (SD13), the selected priority table is stored (SD14). ), The priority order setting process ends.

  That is, as shown in FIG. 7, the control unit 32 has a higher priority of the selected error attribute between the error attribute selected on the priority order setting screen and another error attribute. The priority order is set so that, when a plurality of error attributes are selected, the priority order is set between the selected error attributes according to a predetermined condition, and is stored as a priority order table. It is configured.

  Note that, as shown in FIG. 7, the stored priority order table does not necessarily include the presence / absence of error attribute selection and the order information thereof, and may contain at least priority order information. .

  Next, the display order setting process in step SC1 will be described based on the flowchart of FIG. The display order setting process is a process of setting a display order for the captured image recorded in the memory based on the priority order table, and the various error attributes are associated with the captured image recorded in the memory. The captured images are classified into the captured images that are not and the captured images that are not, and the captured images associated with the various error attributes are classified according to the associated error attributes (SE1).

  Then, a priority order based on the priority order table is set for each classified photographed image group (SE2). For example, in the priority table, as shown in FIG. 7, an error attribute indicating that the exposure level of the photographed image is inappropriate when the priority is first, and the photographed image is second when the priority is second. An error attribute indicating that blurring has occurred, an error attribute indicating that camera shake has occurred in the captured image with priority 3rd, and an error attribute indicating that image interruption has occurred in the captured image Is selected and set, the first priority is assigned to the improperly exposed image group composed of the captured images that are evaluated to be inappropriate for the captured image by the captured image evaluation process, and the captured image is defocused. Out-of-focus in the out-of-focus image group consisting of captured images that are evaluated as occurring, and discontinuity between the captured image and the captured image that are evaluated to have camera shake Priority 3-position other error image group composed of a captured image is evaluated to be generated, the 4-position priority to the normal image group consisting of normal image that has not been evaluated as an error image is set.

  Further, as shown in FIG. 11, for each photographed image group for which the priority order is set, for example, a display order based on the photographing date and time is set for each photographed image (SE3).

  When a plurality of error attributes are associated with one photographed image, the photographed image is classified as corresponding to the error attribute with the higher priority.

  Next, the deletion execution process in step SC2 will be described. For example, as shown in FIG. 12, the photographed image deletion screen displays a predetermined number of photographed images selected from the memory in a list on the display unit 17, and records them in the memory over a plurality of pages. Each captured image is displayed. At this time, the captured images are displayed according to the priority set by the priority setting process and the display order set by the display order setting process.

  That is, among the photographed image groups, the photographed images included in the photographed image group having the set priority order are displayed first, and in the photographed image group, for example, photographed images with the oldest photographing date and time are displayed. Displayed first.

  Specifically, in the example of FIG. 11, each exposure inappropriate image as the exposure inappropriate image group with the highest priority on the first page is displayed according to the display order, and the inappropriate exposure in the inappropriate exposure image group. After all the images are displayed, each of the defocused images in the defocused image group with the second highest priority is displayed according to the display order. The captured images that could not be displayed on the first page are displayed in the order described above after the second page.

  Further, on the photographed image deletion screen, a selection frame 52 is displayed on the currently selected photographed image so that the currently selected photographed image can be identified among the plural photographed images displayed. . The selection frame 52 can be moved onto a desired photographed image by operating the cross key 13 as a selection frame movement key, for example.

  For example, when the set key 14 is operated as a deletion determination key, the control unit 32 deletes image data corresponding to the photographed image selected by the selection frame 52 from the memory, and displays the display. The deleted image selection screen displayed on the unit 17 is updated and displayed on the deleted image selection screen from which the photographed image determined to be deleted is deleted.

  The control unit 32 temporarily enlarges and displays the deletion target image before deleting the photographed image to be deleted when the set key 14 is operated as the deletion determination key. It may be configured to execute reconfirmation to delete the image to be deleted.

  Further, on the deleted image selection screen, the selection frame 52 is operated on the “next page” icon 53 and, for example, the set key 14 is operated as a page transition determination key, so that the deleted image selection screen is not yet displayed. The displayed captured image can be displayed. If there are two or more pages, a “previous page” icon is displayed, and it is possible to return to the previous page by selecting the “previous page” icon.

  Further, when the selection frame 52 is operated on the “end” icon and the set key 14 is operated as an end determination key, for example, the photographed image deletion process is ended. At this time, the display of the deleted image selection screen on the display unit 17 is stopped, and the display of the through image is started again.

  In the deleted image selection screen, the error tag 50 corresponding to the error attribute associated with each captured image may be displayed at one end on the corresponding captured image 51.

  For example, when the error tag 50 is associated with an error attribute indicating that the degree of exposure of the captured image is inappropriate, the error tag 50 generates a camera shake as a symbol of “dew”. If the error attribute indicating that the camera is in motion is associated with the “hand” symbol, and if the error attribute indicating that the image is out of focus is associated with the symbol “pi”, the image is displayed on the captured image. When an error attribute indicating that interruption is occurring is associated, it can be displayed as a “OFF” symbol.

  The deleted image selection screen is not limited to displaying a list of a plurality of photographed images, and may be configured to sequentially display the photographed images one by one. Also at this time, the captured image corresponding to the error attribute having a high priority is displayed first, that is, preferentially.

  As described above, in the digital camera 1, when the remaining recording capacity of the memory becomes smaller than a predetermined capacity threshold, the captured image recorded in the memory is automatically displayed on the display unit 17. By doing so, it is configured to notify the user that the remaining recording capacity of the memory has become small. In addition, if the user sets in advance in the priority order setting mode so that the priority order of the error attribute corresponding to the photographed image that the user wants to delete becomes high, the photographing that the user wants to delete at this time The image is configured to be displayed with priority. That is, at this time, the user can delete the captured image displayed without being confused according to the priority order in which the captured image is displayed.

  Hereinafter, another embodiment will be described. In the above-described embodiment, the captured image deletion processing is performed based on the priority table when the recordable remaining capacity of the memory card 37 or the built-in memory 38 is smaller than a predetermined capacity threshold. A display order is set for the image data (photographed image) recorded in the image data, a photographed image deletion screen is displayed in which predetermined photographed images are sequentially displayed according to the set display order, and the photographed image deletion screen is displayed. The configuration for deleting a captured image instructed by a user from the memory has been described. However, the captured image deletion processing is performed when the recordable remaining capacity of the memory card 37 or the built-in memory 38 is smaller than a predetermined capacity threshold. The image data (captured images) recorded in the memory on the basis of the priority order table. It sets the according deletion order that the set such that said recordable remaining capacity of the memory is equal to or more than a predetermined second volume threshold may automatically be configured to delete the captured image from the memory.

  For example, as shown in FIG. 13, the deletion order is based on each photographed image for each photographed image group for which the priority is set, for example, based on the photographed date and time, as in the display order setting. Is set. The captured images are automatically deleted according to the priority order set by the priority order setting process and the deletion order. That is, among the captured image groups, the captured images included in the set captured image group having a high priority are deleted first, and, for example, captured images with the oldest shooting date and time are included in the captured image group. Deleted first.

  In addition to the embodiment described above, the control unit 32 may be configured to allow the user to select an evaluation item in the captured image evaluation process. By reducing the evaluation items unnecessary for the user, the time spent for the photographed image evaluation process can be shortened.

  In addition to the above-described embodiment, when a captured image is displayed in the reproduction mode, the captured image may be reproduced and displayed in the same order as the captured image deletion screen. That is, for example, when a playback mode is selected by a user operation, the control unit 32 executes the display order setting process, and the priority order set by the priority order setting process and the display order setting process The captured image may be reproduced and displayed according to the display order set by the processing.

  Note that the recordable remaining capacity detected by the remaining capacity detecting means is used for reproducing and displaying the captured image according to the priority order set by the priority order setting process and the display order set by the display order setting process. It is not limited to the time when the amount becomes smaller than a predetermined capacity threshold or in the playback mode. For example, when the power of the digital camera 1 is turned on or the power of the digital camera 1 is turned off. Or when the memory attached to or detached from the digital camera 1 is exchanged.
