FIG. 1 is a block diagram showing the configuration of the electronic camera of this embodiment. FIG. 2 is a diagram illustrating the configuration of the back surface of the electronic camera of the present embodiment.
The electronic camera includes an imaging optical system 11, an imaging device 12, an analog signal processing unit 13, a buffer memory 14, an image processing unit 15, a recording I / F 16, a CPU 17, a monitor 18, a release button 19, and An operation member 20 and a bus 21 are provided. Here, the buffer memory 14, the image processing unit 15, the recording I / F 16, the CPU 17, and the monitor 18 are each connected via a bus 21. The release button 19 and the operation member 20 are each connected to the CPU 17.

The imaging element 12 is disposed on the image space side of the imaging optical system 11. The image sensor 12 photoelectrically converts a subject image by a light beam that has passed through the imaging optical system 11 to generate an analog image signal. The output of the image sensor 12 is connected to an analog signal processing unit 13.
The analog signal processing unit 13 is an analog front-end circuit that performs analog signal processing on the output of the image sensor 12. This analog processing unit performs correlated double sampling, image signal gain adjustment, and A / D conversion of the image signal. The output of the analog signal processing unit 13 is connected to the buffer memory 14. The buffer memory 14 temporarily records captured image data before and after the image processing by the image processing unit 15.

The image processing unit 15 is an ASIC that performs various types of image processing (white balance correction, color interpolation processing, color correction, color conversion processing, gradation conversion, contour enhancement processing, color space conversion, etc.) on a digital image signal. is there.
In addition, the image processing unit 15 executes editing processing of main image data in a reproduction mode described later. In the editing process described above, the image processing unit 15 performs image processing on the original image data of the editing source, and creates a new edited image (an image obtained by performing image processing on the editing source image) separately from the editing source main image. ) Data.

  Note that the types of image processing performed by the image processing unit 15 in the editing processing include, for example, contour enhancement processing, contrast correction processing, red-eye correction processing, saturation adjustment processing, noise reduction processing, and light amount correction processing with image analysis ( For example, a process of specifying a dark part or a highlight part of an image based on the result of image analysis and mainly adjusting the gradation of the specified part), an image composition process of composing one image from a plurality of images, and the like.

  A connector for connecting the recording medium 22 is formed in the recording I / F 16. The recording I / F 16 executes data writing / reading with respect to the recording medium 22 connected to the connector. The recording medium 22 is composed of a hard disk, a memory card incorporating a semiconductor memory, or the like. In FIG. 1, a memory card is illustrated as an example of the recording medium 22.

  The CPU 17 is a processor that performs overall control of the electronic camera. The CPU 17 controls the operation of each part of the electronic camera according to a sequence program corresponding to an operation mode (for example, an imaging mode, a playback mode, etc.). For example, the CPU 17 in the imaging mode executes the imaging process of the main image and various calculations (AF calculation, AE calculation, auto white balance calculation, etc.) required before imaging. The description regarding the playback mode will be described later.

Further, the CPU 17 generates an image file in conformity with the Exif (Exchangeable image file format for digital still cameras) standard. Note that the image file generated by the CPU 17 is recorded in the recording medium 22 described above.
FIG. 3 schematically shows the data structure of the image file. The image file has a header area for recording metadata including imaging conditions (exposure time, aperture value, imaging sensitivity, etc.) and an image area for recording image data. The header area of the image file is composed of a TIFF header and a data area (IFD).

Of the data included in the image file, data that is not supported by the Exif standard is recorded in the header area of the image file using the MakeNote tag of the Exif standard.
The monitor 18 displays various images according to instructions from the CPU 17. As shown in FIG. 2, the monitor 18 in the present embodiment is composed of a liquid crystal display provided on the back surface of the camera housing. The configuration of the monitor 18 may be an electronic viewfinder having an eyepiece. Here, a screen on which an image of the image file is reproduced is displayed on the monitor 18 in the reproduction mode.

The release button 19 receives from the user an AF instruction input by half-press operation and an instruction input of release timing (exposure start of the main image) by full-press operation.
As illustrated in FIG. 2, the operation member 20 includes a mode dial 23, a multi-selector 24, and a plurality of input buttons 25. The mode dial 23 receives an operation for switching the operation mode of the electronic camera from the user.

  The multi-selector 24 includes a main body 24a, a determination button 24b, and a dial 24c. The overall shape of the main body 24a of the multi-selector 24 is formed in a circular shape, and can be inclined in four directions, up, down, left, and right. The main body 24a accepts, from the user, for example, a switching operation of a playback image displayed on the monitor 18 in the playback mode. The decision button 24 b of the multi selector 24 is arranged at the center of the multi selector 24. The dial portion 24c of the multi-selector 24 is formed in an annular shape as a whole, and is configured to be rotatable on the outer periphery of the decision button 24b. For example, in the playback mode, the dial unit 24c and the determination button 24b accept operation of an icon (item selection and item determination) displayed on the monitor 18 in a GUI (Graphical User Interface) format from the user.

Further, each input button 25 receives an input operation set for each operation mode from the user. The input button 25 includes a playback button 25a that activates a playback mode.
Hereinafter, an operation example in the playback mode of the electronic camera of the present embodiment will be described.
First, a case where the user performs an image editing process in the playback mode will be described.

When the user performs an operation for starting the reproduction mode (for example, operation of the mode dial 23, pressing of the reproduction button 25a), the CPU 17 reproduces and displays the image recorded in the image file on the screen of the monitor 18. When the user designates an editing process item with the operation member 20 while the playback screen is displayed, the CPU 17 generates an image file of the edited image in the following manner.
First, the image processing unit 15 performs image processing designated by the user on the data of the original image (the image being displayed on the playback screen). Then, the image processing unit 15 generates new edited image data separately from the editing source image.

Second, the CPU 17 generates each data of the header area of the edited image in accordance with the Exif standard. As for the metadata of the imaging conditions related to the edited image, the data of the original image file is copied and recorded.
Thirdly, the CPU 17 records data indicating the type of image processing in the editing process and a file path indicating the location of the editing source image file in the header area of the image file of the edited image. In the case of the image composition process, a plurality of file paths of the image file as the editing source are recorded in the header area.

Further, the CPU 17 records a file path indicating the location of the image file of the edited image in the header area of the original image file. Thereby, when the file path is detected from the header area of the image file, the CPU 17 can grasp the location of another image file related to the image file.
Here, as an example, the above file path is constituted by character string data describing a route from the root directory or drive name to the recording position of the target image file. Of course, the file path may be a relative path. The file path data is recorded in each header area using the MakerNote tag.

Next, an operation when the user views a plurality of images by switching the display image on the monitor 18 in the playback mode will be described with reference to the flowcharts of FIGS. 4 and 5.
Here, in the examples of FIGS. 4 and 5, for convenience of explanation, it is assumed that nine frames of image files from image N1 to image N9 recorded on the recording medium 22 are reproduced. The image numbers (N1 to N9) indicate the arrangement order of the file numbers of the respective images. Further, images N3, N4, and N5 are edited images with the image N1 as an original image. Furthermore, the images N7 and N8 are edited images having the image N3 as an original image. FIG. 6 schematically shows the relevance of each image.

  Step 101: The CPU 17 scans the header areas of all image files recorded on the recording medium 22. Then, the CPU 17 generates link data indicating the relationship between the original image and the edited image between the image files based on the file path detected from the header area of the image file. By generating the link data, the CPU 17 can grasp the relationship between the image files hierarchically. Therefore, the CPU 17 associates a plurality of edited images (for example, the images N3, N4, and N5 for the image N1 and the images N7 and N8 for the image N3) that are directly related to the same original image by link data. It becomes possible to extract.

Step 102: The CPU 17 initializes the related image display flag by turning it off.
Step 103: The CPU 17 reads image data from the image file to be reproduced. When the image to be reproduced is read for the first time in the reproduction mode, the CPU 17 reads the image from the image file at the beginning (N1) or the end (N9) of the file number.

  Step 104: The CPU 17 determines whether or not the related image display flag is off. If the flag is off (YES side), the CPU 17 proceeds to S105. On the other hand, when the flag is on (NO side), the CPU 17 proceeds to S115. In this case (NO side of S104), the CPU 17 operates in a related image display mode described later.

  Step 105: The CPU 17 determines whether or not there is an image file relevant to the image file to be reproduced (S103). Specifically, the CPU 17 refers to the link data (S102) and determines whether or not there is an original image or an edited image for the image to be reproduced. If there is no related image file (YES side), the CPU 17 proceeds to S106. On the other hand, if there is a related image file (NO side), the CPU 17 proceeds to S109.

Step 106: In this case, the CPU 17 displays only the reproduced image read from the image file to be reproduced on the monitor 18. FIG. 7 shows an example of the display screen of the monitor 18 in S106.
Step 107: The CPU 17 determines whether or not a display switching operation to the next image (for example, an operation on the main body 24a of the multi-selector 24) has been received from the user. If the above requirement is satisfied (YES side), the CPU 17 proceeds to S108. On the other hand, when the above requirement is not satisfied (NO side), the CPU 17 waits for an input from the user.

Step 108: The CPU 17 designates, as a reproduction target, an image file whose file number is arranged one order after (or one before) the reproduction target image file. Thereafter, the CPU 17 returns to S103 and repeats the above operation.
As an example, consider a case where the user performs a display switching operation to the next image when the image N2 is displayed in S106. In this case, the image N3 (or the image N1) is displayed on the monitor 18 after switching according to the order of the file numbers.

Step 109: In this case, the CPU 17 displays the reproduced image read from the image file to be reproduced and the browse key for the related image on the monitor 18. FIG. 8 shows an example of the display screen of the monitor 18 in S109. On the display screen in FIG. 8, a browse key for a related image is displayed in the GUI format below the reproduced image.
Here, there are two types of browsing keys: an original image key for browsing the original image of the reproduced image and an edited image key for browsing the edited image of the reproduced image. The original image key is displayed on the monitor 18 only when the CPU 17 determines that the reproduced image has an original image based on the link data. Similarly, the edited image key is displayed on the monitor 18 only when the CPU 17 determines that there is an edited image generated from the reproduced image based on the link data. FIG. 8 shows a state where both the original image key and the edited image key are displayed on the monitor 18.

  Then, when the user operates the cursor or the like on the monitor 18 with the operation member 20 to input to the browse key, the CPU 17 displays a related image (original image or edited image) corresponding to the browse key on the monitor 18. . Here, when there are a plurality of edited images generated from the displayed reproduced image, the CPU 17 displays the edited image having the oldest file number among the above-mentioned edited images when there is an input to the editing image viewing key. . If there are a plurality of edited images generated from the displayed reproduced image, the CPU 17 may be configured to display an arbitrary edited image designated by the user on the monitor 18.

Step 110: The CPU 17 determines whether or not an input operation to the browse key for the related image has been received. If the above requirement is satisfied (YES side), the CPU 17 proceeds to S111. On the other hand, if the above requirement is not satisfied (NO side), the CPU 17 proceeds to S113.
Step 111: The CPU 17 turns on the related image display flag. Further, the CPU 17 records the file path of the current image file to be reproduced (image file of the initial image).

Step 112: The CPU 17 designates an image file (original image or edited image) corresponding to the viewing key as a reproduction target. Thereafter, the CPU 17 returns to S103 and repeats the above operation. In this case, since the related image display flag is on, the CPU 17 shifts to a related image display mode (S115) described later in S104.
As an example, consider a case where the user inputs a browse key (edited image key) when the image N1 is displayed in S109. In this case, the CPU 17 shifts to the related image display mode, and the image N3 is displayed on the monitor 18 after switching. The display screen in the related image display mode will be described later in S115.

Step 113: The CPU 17 determines whether or not a display switching operation to the next image (for example, an operation on the main body 24a of the multi-selector 24) has been received from the user. If the above requirement is satisfied (YES side), the CPU 17 proceeds to S114. On the other hand, if the above requirement is not satisfied (NO side), the CPU 17 returns to S110 and repeats the above operation.
Step 114: The CPU 17 designates an image file whose file number order is one after (or one before) the image file to be reproduced as a reproduction target. Thereafter, the CPU 17 returns to S103 and repeats the above operation.

As an example, consider a case where the user performs a display switching operation to the next image when the image N1 is displayed in S109. In this case, the image N2 (or image N9) is displayed on the monitor 18 after switching according to the order of the file numbers.
Step 115: The CPU 17 in the related image display mode displays the original image or the edited image of the previous display image on the monitor 18. FIG. 9 shows an example of the display screen of the monitor 18 in S115. In the display screen in FIG. 9, a mode display indicating the related image display mode is displayed together with the related image. Further, below the related image, a related image browsing key (original image key and edited image key) and a return key are displayed in the GUI format.

  Here, when the user operates the cursor or the like on the monitor 18 with the operation member 20 to input the return key, the CPU 17 again displays the initial image displayed before entering the related image display mode on the monitor 18. indicate. When the user presses the play button 25a in the display state of the display screen in S115, the CPU 17 cancels the related image display mode and shifts to a normal display state. In addition, since the description about the browsing key of a related image is common with S109, duplication description is abbreviate | omitted.

Step 116: The CPU 17 determines whether or not an input operation to the browse key for the related image has been accepted. If the above requirement is satisfied (YES side), the CPU 17 proceeds to S117. On the other hand, if the above requirement is not satisfied (NO side), the CPU 17 proceeds to S120.
Step 117: The CPU 17 designates an image file (original image or edited image) corresponding to the viewing key as a reproduction target.

  Step 118: The CPU 17 determines whether or not the image file designated as the reproduction target in S117 is an initial image. Specifically, the CPU 17 determines whether or not the file path of the image file to be reproduced in S117 matches the file path recorded in S111. If the above requirement is satisfied (YES side), the CPU 17 proceeds to S121. On the other hand, if the above requirement is not satisfied (NO side), the CPU 17 returns to S103 and repeats the above operation while remaining in the related image display mode.

Note that the NO side in S118 corresponds to, for example, switching the display from the image N1 to the image N3 by operating the browse key and switching the display from the image N3 to the image N7 by operating the browse key.
Step 119: The CPU 17 determines whether or not an input operation to the return key has been accepted. If the above requirement is satisfied (YES side), the CPU 17 proceeds to S120. On the other hand, if the above requirement is not satisfied (NO side), the CPU 17 proceeds to S122.

Step 120: The CPU 17 designates the image file of the initial image as a reproduction target based on the file path recorded in S111.
Step 121: This case corresponds to switching the display to the initial image before entering the related image display mode. Therefore, the CPU 17 turns off the related image display flag and cancels the related image display mode. Thereafter, the CPU 17 returns to S103 and repeats the above operation.

  In addition, the following cases correspond to the case of S121, for example. (1) When the user switches the display from the image N1 to the image N3 by operating the browse key and then returns the display from the image N3 to the image N1 by operating the browse key (YES in S118), (2) For example, the display is switched in the order of the images N1, N3, and N7 by the operation of the browse key and the display is returned to the image N1 by the return key thereafter (YES side of S119).

Step 122: The CPU 17 determines whether or not an input operation to the reproduction button 25a has been accepted. If the above requirement is satisfied (YES side), the CPU 17 proceeds to S123. On the other hand, if the above requirement is not satisfied (NO side), the CPU 17 proceeds to S124.
Step 123: The CPU 17 turns off the related image display flag and cancels the related image display mode. Thereafter, the CPU 17 returns to S103 and repeats the above operation without changing the image file to be reproduced. In this case, the current playback target image is displayed on the monitor 18 in the state of S109 (that is, the mode display and the return key are not displayed).

Step 124: The CPU 17 determines whether or not a display switching operation to the next image (for example, an operation on the main body 24a of the multi-selector 24) has been received from the user. If the above requirement is satisfied (YES side), the CPU 17 proceeds to S125. On the other hand, if the above requirement is not satisfied (NO side), the CPU 17 returns to S116 and repeats the above operation.
Step 125: Based on the link data, the CPU 17 extracts other related images belonging to the same hierarchy as the display image in S115 with reference to the link source image. Then, the CPU 17 designates an image file whose file number arrangement order is one after (or one before) the image file to be reproduced from the group of related images described above as a reproduction target. Thereafter, the CPU 17 returns to S103 and repeats the above operation.

  As an example, consider a case where the user performs a display switching operation to the next image after switching the display from the image N1 to the image N3 by the operation of the browse key and shifting to the related image display mode. In this case, the CPU 17 extracts images N4 and N5 in the same hierarchy as the display image (N3) with respect to the link source image (N1). Each time the operation for switching to the next image is performed in the related image display mode, the image is repeatedly displayed on the monitor 18 in the order of N4, N5, N3, N4,. If there is no other related image in S125, the CPU 17 disables the display switching operation to the next image and proceeds to S116. Above, description of FIG. 4, FIG. 5 is complete | finished.

  Hereinafter, the effect of this embodiment is demonstrated. In the electronic camera of this embodiment, the CPU 17 manages the relevance of the image file based on the file path recorded in the header area of the image file. Then, when there is an edited image or the like in the image being reproduced, the CPU 17 displays a browse key on the monitor 18 to alert the user. Further, the CPU 17 shifts to a related image display mode in accordance with a user's operation of a viewing key so that an image group related to the link source image can be easily browsed. Note that since the mode display indicating the related image display mode is performed on the monitor 18 in the related image display mode, the user is not confused.

  For example, considering the case where the original image and the edited image are not recorded sequentially, in the normal playback mode, the user needs to perform an operation of sequentially sending unrelated images in order to compare the two images. Become. However, in the above embodiment, since the user can easily switch between the display of the original image and the edited image by operating the browse key, the user can easily confirm the effect of image editing by comparing the original image and the edited image. can do. Furthermore, since the user can easily switch the display to the initial image before entering the related image display mode and cancel the related image display mode, the convenience of the playback mode of the electronic camera is further improved.

In the present embodiment, the link data is generated when the CPU 17 needs it based on the file path recorded in the header area of the image file. Therefore, it is possible to efficiently manage the relationship between images during reproduction with less data.

In the above embodiment, the program of the image processing apparatus is executed by the CPU 17.

  (2) In the above-described embodiment, the example in which the file path is recorded in the original image file and the edited image file has been described. However, the present invention is not limited to the above embodiment, and the file path of the other party may be recorded only in one of the edited image or the image file of the original image. In this case, it is particularly preferable to record the file path of the original image in the image file of the edited image.

(3) In the above embodiment, when a folder or the like for recording an image file is determined in advance, the CPU 17 records information (for example, a file name or the like) that can identify the image file of the other party instead of the file path. The relevance of image files may be managed.
(4) When erasing an image file whose file path is recorded in the header area, the CPU 17 may update or delete the file path of the edited image or the image file of the original image related to the erasure target. . For example, when the original image is deleted, the CPU 17 may re-associate the remaining image file of the edited image with a higher-order original image than the image to be deleted.

(5) In the above embodiment, the example in which the image file of the edited image is generated by the image processing in the reproduction mode is shown, but the present invention is not limited to this. For example, the present invention may be applied to an image file of an edited image that is automatically generated when an electronic camera captures an image.
