  FIG. 1 is a block diagram showing the configuration of the electronic camera of this embodiment. The electronic camera includes an imaging optical system 11, an imaging device 12, an AFE 13, an image processing unit 14, a buffer memory 15, a recording I / F 16, a CPU 17, a monitor 18, an operation member 19, and a bus 20. have. Here, the image processing unit 14, the buffer memory 15, the recording I / F 16, the CPU 17, and the monitor 18 are respectively connected via a bus 20. The operation member 19 is connected to the CPU 17.

  The imaging optical system 11 includes a plurality of lens groups including a zoom lens and a focusing lens. In FIG. 1, the imaging optical system 11 is illustrated as a single lens for simplicity. In the case of a single-lens reflex electronic camera, the lens unit including the imaging optical system 11 is configured to be replaceable with the electronic camera.

  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 the AFE 13. In the shooting mode, which is one of the operation modes of the electronic camera, the image sensor 12 captures a recorded image (main image) in response to a full press operation of a release button described later.

  The AFE 13 is an analog front end circuit that performs analog signal processing on the output of the image sensor 12. The AFE 13 performs correlated double sampling, image signal gain adjustment, and image signal A / D conversion. The output of the AFE 13 is connected to the image processing unit 14.

  The image processing unit 14 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. The image processing unit 14 also performs image resolution conversion processing and the like.

  Further, the image processing unit 14 executes image editing processing of the data of the main image in an image editing mode described later. In the image editing process described above, the image processing unit 14 performs image processing on the data of the editing source image, and creates a new editing image (an image obtained by performing image processing on the editing source image) separately from the editing source image. Generate data for

  The buffer memory 15 temporarily records image data before and after the image processing by the image processing unit 14.

  A connector for connecting the storage medium 21 is formed in the recording I / F 16. The recording I / F 16 executes data writing / reading with respect to the storage medium 21 connected to the connector. The storage medium 21 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 storage medium 21.

  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, a shooting mode, a playback mode, an image editing mode, etc.). For example, the CPU 17 in the shooting mode performs imaging processing of the main image and various calculations (AF calculation, AE calculation, auto white balance calculation, etc.) required before imaging.

  Further, the CPU 17 generates an image file in conformity with the Exif (Exchangeable image file format for digital still cameras) standard. The image file generated by the CPU 17 is recorded in the storage medium 21 described above.

  Here, FIG. 2 schematically shows the data structure of the image file. The image file has a header area for storing metadata including imaging conditions (exposure time, aperture value, imaging sensitivity, etc.) and an image area for storing 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, the data not defined in the Exif standard is recorded in the header area of the image file using the Excite MakerNote tag. Further, when generating an image file related to the edited image, the CPU 17 generates metadata using the imaging conditions of the image file of the editing source.

  The CPU 17 in the playback mode reads the image file data from the storage medium 21 and displays the playback image on the monitor 18.

  The monitor 18 displays various images according to instructions from the CPU 17. 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. Note that the CPU 17 can also display on the monitor 18 a menu screen on which various setting items can be input.

  The operation member 19 receives various input operations from the user. The operation member 19 in the present embodiment includes a release button, a cross-shaped cursor key, and an enter button. In the shooting mode, the release button of the operation member 19 receives from the user an AF instruction input by a half-press operation and an instruction input to start capturing the main image by a full-press operation. Further, the cursor key and the determination button of the operation member 19 accept various operations according to each operation mode from the user. For example, the CPU 17 in the image editing mode performs icon operation (item selection and item determination) displayed on the monitor 18 in the GUI (Graphical User Interface) format via the cursor key and the determination button of the operation member 19. Accept from user.

  Hereinafter, an operation example in the image editing mode of the electronic camera of the present embodiment will be described. For example, in a state where an image is being reproduced on the monitor 18 in the reproduction mode, when the CPU 17 detects an operation for starting the image editing mode, the menu screen of the image editing mode is displayed on the monitor 18.

  FIG. 3 is a diagram illustrating an example of a menu screen in the image editing mode. This menu screen displays a list of processing items that can be selected in the image editing mode. Specifically, in the menu screen of FIG. 3, “D-lighting”, “red-eye correction processing”, “trimming”, “monotone”, “filter effect”, “color customization”, “image composition processing”, “editing” Each item of “comparison of images before and after” is displayed. Note that the display processing on the menu screen is controlled by the CPU 17.

  Among the above items, “D-lighting”, “red-eye correction processing”, “trimming”, “monotone”, “filter effect”, “color customization”, and “image composition processing” are the contents of the image editing processing, respectively. It is an item about. Note that the item “Comparison of images before and after editing” cannot be selected when the playback image displayed in the playback mode is not related to image editing (when the image file does not have identification data described later). It becomes a state.

  Here, the contents of the image editing process on the menu screen will be described. In “D-lighting”, the image processing unit 14 specifies a dark part or a highlight part of the original image by image analysis, and adjusts the gradation of the image centering on the dark part or the highlight part, thereby editing the edited image. Generate. In the “red-eye correction process”, the image processing unit 14 generates an edited image by reducing the red eyes of a person included in the original image by image processing. For example, the image processing unit 14 detects a red-eye area from a face area in the image by a known face detection process, and performs correction to reduce the lightness or saturation of the detected red-eye area. In “trimming”, the image processing unit 14 partially cuts out an image to be processed to generate an edited image. In “monotone”, the image processing unit 14 generates an edited image in which the original image is expressed by a single color of light and shade. In the “filter effect”, the image processing unit 14 performs image processing on the original image to generate an edited image similar to that when the filter is attached. For example, the image processing unit 14 executes image processing (sky light) for suppressing the bluishness of the image at the editing source, image processing for warming the image at the editing source (warm tone), and the like as the “filter effect”. In “color customization”, the image processing unit 14 adjusts the color tone of the original image to generate an edited image. Further, in the “image composition process”, the image processing unit 14 composes two editing source images to generate one edited image.

  Further, when generating an image file of an edited image, the CPU 17 records identification data indicating the image of the editing source in the header area. Specifically, the CPU 17 records the image file name of the editing source in the header area of the image file of the edited image. In particular, in the case of “image composition processing”, the CPU 17 records the two editing source image file names in the header area. Further, the CPU 17 records the contents of image editing processing (trimming, etc.) in the header area of the image file of the edited image. The image file of the edited image generated in the image editing mode is finally recorded on the storage medium 21 under the control of the CPU 17.

  On the other hand, the CPU 17 records identification data (image file name of the edited image) indicating the edited image generated from the original image in the header area of the original image file. Note that when the editing source image file is in a state in which data writing is prohibited in order to prevent image falsification, the CPU 17 omits the recording of identification data for the editing source image file.

  Here, when a plurality of different image editing processes are performed on one image, a plurality of image file names of the edited image are recorded in one image file. Further, when image editing processing is further performed on the edited image, the image file name that is the editing source for the image and the image file name of the edited image further derived from the image are one. Each is recorded in an image file (see FIG. 2).

  Next, an example of the operation of the electronic camera when the item “image comparison before and after editing” is selected will be described in detail with reference to the flowchart of FIG. In this “image comparison before and after editing”, a comparison screen for simultaneously displaying two images before and after the image editing process is displayed on the monitor 18 under the control of the CPU 17.

  Step S101: The CPU 17 designates the reproduced image displayed on the monitor 18 before starting the image editing mode as a reference image.

  Step S102: The CPU 17 refers to the header area of the image file of the reference image (S101), and acquires identification data (the image file name of the editing source or the image file name of the edited image) included in the image file. As a result, the CPU 17 can search the storage medium 21 for an editing source image and an editing image related to the reference image.

  Step S103: The CPU 17 extracts an image file that matches the file name of the identification data (S102) from among the image files stored in the storage medium 21.

  Here, after extracting the image file, the CPU 17 checks the header area in the image file and eliminates an image unrelated to the reference image. As an example, the CPU 17 pays attention to the “total number of releases” of the header area included in the Exif standard image file. If the “total number of releases” of the extracted image file is different from the value of the image file of the reference image, the CPU 17 excludes the image file. This is because after the original image or the like is deleted from the storage medium 21, another image may be recorded with the same file name as the original image. Note that if there is identification data indicating the image file of the reference image, the CPU 17 may determine that the image file is related to the reference image.

  Step S104: The CPU 17 determines whether or not all the image files corresponding to the identification data (S102) have been found. If the above requirement is satisfied (YES side), the process proceeds to S107. On the other hand, if the above requirement is not satisfied (NO side), the process proceeds to S105.

  Step S105: The CPU 17 determines whether no image file corresponding to the identification data (S102) has been found. If the above requirement is satisfied (YES side), the CPU 17 displays a message on the monitor 18 that there is no other image related to the reference image, and terminates the process of FIG. 4 without displaying the above comparison screen. To do. On the other hand, if the above requirement is not satisfied (NO side), the process proceeds to S106.

  Step S106: The CPU 17 excludes identification data that cannot be found from the identification data included in the image file of the reference image from the processing target. Here, the identification data excluded from the processing target in S106 is not used for generation of link data described later.

  Step S107: The CPU 17 generates link data indicating the correspondence relationship between the image files before and after editing according to the processing result of S103. This link data is used by the CPU 17 when switching images to be compared on the comparison screen.

  That is, the CPU 17 selects the image file of the reference image among the image files stored in the storage medium 21 and the image file extracted in S103 (the image file that is the editing source of the reference image or the image file of the edited image of the reference image). ) And link data is generated.

  The CPU 17 also reads identification data from the image files extracted in S103, and records in the link data how many original images and edited images exist for these image files.

  Step S108: The CPU 17 displays a comparison screen for comparing images before and after editing on the monitor 18. Under the control of the CPU 17, the two images before and after the image editing process (the original image and the edited image) are displayed side by side in the reduced state on the comparison screen. Note that, on the comparison screen of the present embodiment, the editing source image is displayed on the left side and the editing image is displayed on the right side.

  The comparison screen displays the image file name of each display image and the contents of the image editing stored in the image file of the edited image under the control of the CPU 17. The CPU 17 displays a pointer for switching the images to be compared on the comparison screen based on the link data (S107).

  FIG. 5 shows an example of the comparison screen in S108. Here, in the following example, the reference image N1 is an edited image generated by performing image editing processing on the image N2. Further, it is assumed that an edited image N3 different from the reference image N1 exists in the image N2. The images N4 and N5 are edited images generated by performing image editing processing on the reference image N1, respectively. The image N5 is an edited image (synthesized image) generated by combining the reference image N1 and the image N6. Further, the image N7 is an edited image generated by performing image editing processing on the image N4.

  The CPU 17 displays the reference image N1 (left side in FIG. 5) and the edited image N4 (right side in FIG. 5) for the image N1 side by side on the monitor 18 in the initial state (FIG. 5) of the comparison screen in S108. Further, a selection cursor is placed on the reference image N1 on the comparison screen so as to be superposed by the control of the CPU 17.

  Further, based on the link data (S107), the CPU 17 displays a pointer indicating another image related to the reference image N1 and a pointer indicating another image related to the displayed edited image N4 on the comparison screen. . In FIG. 5, on the left side of the reference image N1, a pointer indicating the editing source image N2 of the reference image N1 is displayed. In FIG. 5, a pointer indicating the edited image N5 of the reference image N1 is displayed below the edited image N4. Further, a pointer indicating the edited image N7 is displayed on the right side of the edited image N4 in FIG.

  As an example, when there is no image file of the edited image N5 in the storage medium 21, the CPU 17 does not generate link data related to the image N5 (S106), so a pointer indicating the edited image N5 is displayed on the comparison screen of FIG. It will not be done.

The user can select a display image on the comparison screen and specify each pointer to the CPU 17 by operating a cursor on the screen via the operation member 19. When the CPU 17 receives an input of an enlargement instruction with the cursor placed on the comparison screen display image, the CPU 17 enlarges and displays the image specified by the cursor. When the CPU 17 further receives an input for designating the direction of the pointer in a state where the cursor is placed on the display image on the comparison screen, the CPU 17 performs display switching of the comparison screen.

  Step S109: The CPU 17 determines whether or not an input of an enlargement instruction for one image of the comparison screen has been accepted. If there is the input (YES side), the process proceeds to S110. On the other hand, if there is no input (NO side), the process proceeds to S111.

  Step S110: The CPU 17 enlarges and displays the image designated by the cursor on the comparison screen. For example, the CPU 17 displays one image of the comparison screen on the monitor 18 in the full screen in the same format as the playback in the normal playback mode. In addition, after cancellation | release of the enlarged display in S110, CPU17 transfers a process to S113.

  Step S111: The CPU 17 determines whether or not an input relating to a pointer on the comparison screen has been received. If there is the input (YES side), the process proceeds to S112. On the other hand, if there is no input (NO side), the process proceeds to S113.

  Step S112: The CPU 17 executes display switching of the comparison screen (S108). Specifically, the CPU 17 leaves one image included in the original comparison screen and replaces the other image with an image corresponding to the designated pointer. Then, the CPU 17 displays the two replaced images side by side on the comparison screen. Further, the CPU 17 generates new link data in the same manner as the processes from S102 to S108, and displays a pointer based on the link data on the new comparison screen of S112.

  6 to 8 are diagrams respectively showing new comparison screens that are transitioned from the comparison screen of FIG. 5 according to the input of the pointer. FIG. 6 shows a new comparison screen that is transitioned by the pointer indicating the image N2. In the comparison screen of FIG. 6, the image N2 that is the editing source (the left side in FIG. 6) and the image N1 that is the edited image of the image N2 (the right side in FIG. 6) are displayed side by side. In FIG. 6, a pointer indicating an image N3 which is an edited image of the image N2 is displayed below the image N1. In FIG. 6, a pointer indicating an image N4 that is an edited image of the image N1 is displayed on the right side of the image N1.

FIG. 7 shows a new comparison screen that is transitioned by the pointer indicating the image N5. On the comparison screen in FIG. 7, one editing source image N1 (left side in FIG. 7) and an image N5 (right side in FIG. 7) that is a composite image using the image N1 are displayed side by side. Then, on the left side of the image N1 in FIG. 7, a pointer indicating the image N2 that is the image that is the editing source of the image N1 is displayed. Further, in FIG. 7, a pointer indicating an image N6 which is the other editing source image with respect to the image N5 is displayed below the image N1. Further, on the upper side of the image N5 in FIG. 7, a pointer indicating the image N4 is edited image in the image N1 is displayed.

  FIG. 8 shows a new comparison screen that is transitioned by the pointer indicating the image N7. On the comparison screen in FIG. 8, the image N4 (the left side in FIG. 8) as the editing source and the image N7 (the right side in FIG. 8) that is the edited image of the image N4 are displayed side by side. Then, on the left side of the image N4 in FIG. 8, a pointer indicating the image N1, which is an image that is the editing source for the image N4, is displayed.

  Step S113: The CPU 17 determines whether or not an instruction to end display of the comparison screen has been received. If there is a display end instruction (YES side), the CPU 17 ends the process of FIG. On the other hand, when there is no display end instruction (NO side), the CPU 17 returns to S109 and repeats the above operation. This is the end of the description of FIG.

  Hereinafter, functions and effects of the electronic camera of the present embodiment will be described. In the electronic camera of this embodiment, the CPU 17 displays the images before and after image editing side by side on the monitor 18 based on the identification data recorded in the image file. Then, the CPU 17 enlarges and displays one image displayed on the comparison screen in accordance with a user operation. Therefore, according to the configuration of the present embodiment, the user can confirm the effect of image editing easily and quickly by comparing and observing the original image and the edited image.

  Furthermore, considering the case where the original image and the edited image are not recorded in sequential numbers, in the normal playback mode, the user needs to sequentially send unrelated images in order to compare the two images. Become. However, in the above embodiment, the image group having relevance can be easily switched and displayed on the comparison screen by image editing, so that the convenience of the electronic camera is further improved.
