  In recent years, although the size of the LCD, which is the image display unit of a digital camera, tends to increase, considering the miniaturization of the digital camera body, for example, about 2.5 to 3.0 inches is the limit. This is considerably smaller than that of a PC display or a television. Therefore, depending on the effect of image processing or the range where the effect reaches, there is a possibility that the difference can hardly be confirmed with the naked eye on the LCD. In particular, the tendency is remarkable in thumbnail display. For example, in the case of red-eye correction processing that automatically corrects red-eye of human images, even if the processing result is displayed as a thumbnail on the camera LCD, the effect can be confirmed with the naked eye. It is difficult.

  However, in the conventional technique, even for a thumbnail image for which it is difficult to confirm the effect of the image processing even if it is displayed, the image processing is performed in the same manner as the main image. There was a problem.

  The present invention has been made in view of such problems, and performs image processing on thumbnail images that allow the user to confirm the effects of image processing, etc., while providing the effects of image processing to the user. The purpose is to perform image processing at high speed.

  Accordingly, the present invention provides an image processing apparatus that captures an image and records the image on a recording medium, the low-resolution image generating unit that generates a low-resolution image having a lower resolution than the captured image after capturing the image, and the recording medium Image processing execution means for performing image processing on the image recorded in the image, detection means for detecting that image processing has been started in the image processing execution means, and detection of image processing being started in the detection means, Determination means for determining whether or not to regenerate a low resolution image related to a target image based on a low resolution image regeneration condition that is a condition of whether or not to regenerate a low resolution image, The process execution unit performs the image process even on the low-resolution image related to the target image when the determination unit determines to perform the regeneration.

  By adopting such a configuration, for example, for a certain low resolution image, image processing is performed on a certain low resolution image in the same manner as the target image (or the main image), and for a certain low resolution image. Can prevent image processing on the target image. Therefore, it is possible to perform image processing at high speed while performing image processing on a thumbnail image for which the user can confirm the effect of the image processing, etc., and providing the user with the effect of the image processing.

  The image processing apparatus corresponds to, for example, a digital camera described later.

  The present invention may be an image processing method, a program, and a recording medium.

  The power button 251 is a button used to start and stop the digital camera 100 or when turning on / off the main power of the digital camera 100. The menu button 252 is a menu for setting various imaging conditions and for displaying the state of the digital camera 100 (the menu includes a plurality of items that can be selected and / or whose values can be changed. This button is used to display Here, modes or items that can be set include, for example, a shooting mode (for example, a program mode, an aperture priority mode, a shutter speed priority mode, etc. for determining exposure), a panorama shooting mode, an information code reading mode, and a playback. Mode etc. are included. Multi-screen playback / erase mode, PC connection mode (PC is a computer such as a personal computer), exposure compensation, flash setting, single / continuous switching, self-timer setting, recording quality setting, date / time setting, recording It also includes image protection.

  For example, when the menu button 252 is pressed, the system control circuit 50 causes the image display unit 28 to display a menu. The menu may be synthesized and displayed on the image being captured, or may be displayed alone (for example, displayed on a predetermined background color). When the menu button 252 is pressed again while the menu is displayed, the system control circuit 50 ends the display of the menu on the image display unit 28.

  The decision button 253 is pressed when a mode or item is decided or selected. When the determination button 253 is pressed, the system control circuit 50 sets the mode or item selected at that time. The display button 254 is used to select display / non-display of shooting information for a captured image and to switch whether the image display unit 28 functions as an electronic viewfinder.

  A left button 255, a right button 256, an up button 257, and a down button 258 (direction selection key) are options (for example, items and images) selected from a plurality of options such as a cursor or a highlight portion. Used to change. Alternatively, it is used to change the position of an index that identifies the selected option, or to increase or decrease a numerical value (for example, a numerical value indicating a correction value or a date). Here, the left button 255, the right button 256, the up button 257, and the down button 258 select only one item from a plurality of items, and the user interface so that two or more items can be selected. Is preferably configured. For example, when the left button 255, the right button 256, the upper button 257, and the lower button 258 are operated while the determination button 253 is pressed, the system control circuit 50 displays two or more items specified by the operation. Configured to recognize as selected.

  As described above, the shutter button 260 instructs the system control circuit 50 to start AF processing, AE processing, AWB processing, EF processing, and the like in a half-pressed state, for example. Configured to instruct.

  The recording / playback switch 261 is used to switch the recording mode to the playback mode and the playback mode to the recording mode.

  The jump key 262 functions in the same manner as the direction selection key, and changes or selects an option (for example, an item or an image) selected from a plurality of options such as a cursor or a highlight portion. Used to change the position of the indicator that identifies the choice being made. The cursor movement by the jump key may be set earlier or larger than that by the direction selection key.

  In place of the operation system as described above, a dial switch may be employed, or another operation system may be employed.

  Hereinafter, the operation of the digital camera 100 in the present embodiment will be described.

  By setting the recording / playback changeover switch 261 to the playback side, the digital camera 100 browses the captured image and transitions to a playback mode in which various image processes can be performed.

  When the user presses the menu button 252 in the playback mode, a playback menu screen 501 is displayed on the image display unit 28 (see FIG. 3). Here, FIG. 3 is a diagram illustrating an example of a reproduction menu screen.

  The reproduction menu screen 501 includes a red-eye correction menu 502 for correcting a person's red-eye, a retouch my color menu 503 for changing the color tone of an image, a trimming menu 504 for cutting out a part of the image, a resize menu 505 for changing the size of the image, and the like. is there. The playback menu screen 501 also includes a rotation menu 506 for rotating an image, an erase menu 507 for deleting an image, and the like. Here, the discussion proceeds with red-eye correction as an example. Since the red-eye search algorithm and its process are not directly related to the present embodiment, only the operation procedure for executing the red-eye correction will be described here, and the detailed description thereof will be omitted.

  The red-eye phenomenon is a phenomenon in which when a person is photographed using a strobe, the eye color is photographed in red. This occurs because strobe light incident on the pupil that is open in the dark reflects the blood vessels of the retina. Many digital cameras in recent years automatically detect the position of a person's face and eyes in a photographed person image, and if a red-eye phenomenon occurs, correct the red eye automatically or semi-automatically based on that information. It has a red-eye correction function. It is assumed that the red-eye correction function of this embodiment has the same function as that described above.

  When the red-eye correction menu 502 is selected from the reproduction menu screen 501 and executed, a target image 601 is displayed (FIG. 4). FIG. 4 is a diagram illustrating an example of a red-eye search menu in the red-eye correction menu 502.

  Here, the image where the red-eye phenomenon occurs is an image using a strobe at the time of shooting, so only images using the strobe may be displayed in this menu, or face recognition is automatically performed for all images. The image with the face recognized may be displayed.

  In this menu, the user selects an image to be corrected with the left button 255 and the right button 256 and displays it on the image display unit 28. After the display, when the user presses the enter button 253, the system control circuit 50 detects the red eye and displays the detected frame 701 on the image display unit 28 (FIG. 5). FIG. 5 is a diagram illustrating an example of a red-eye correction execution menu in the red-eye correction menu 502.

  The user selects the red-eye correction execution menu 702 if the red-eye within the frame 701 shown in FIG. The operation after the red-eye correction execution menu 702 is selected will be described below.

FIG. 6 is a flowchart showing the overall operation in the present embodiment.
When the user selects the red-eye correction execution menu 702, the system control circuit 50 first detects that (step S301) and analyzes the content of the selected image processing (step S302).

  When the analysis is completed, the system control circuit 50 refers to the thumbnail regeneration determination table stored in the nonvolatile memory based on the analysis result (step S303).

  FIG. 7 is a diagram illustrating an example of the thumbnail regeneration determination table. The thumbnail regeneration determination table is configured as shown in FIG. 7, and for each image processing that can be realized by the digital camera 100, defines whether to regenerate the thumbnail image when the image processing is performed. is doing. According to the thumbnail regeneration determination table, in the case of red-eye correction processing, thumbnail regeneration is defined to be based on the range of effects. Therefore, first, the system control circuit 50 proceeds to the next step while turning off the thumbnail regeneration flag.

  For example, when the user selects the image rotation menu 506 from the playback menu screen 501, the thumbnail regeneration determination table is defined as needing thumbnail regeneration. Therefore, the system control circuit 50 turns on the thumbnail regeneration flag (step S307). The definition of the thumbnail regeneration determination table is based on whether or not the effect of the image processing to be performed can be recognized by human eyes even in the thumbnail display. That is, when the image is rotated, the effect can be seen with the naked eye even in the thumbnail display, but with the red eye correction, the effect is hardly recognized with the naked eye in the thumbnail display. Therefore, it does not make much sense to bother to regenerate thumbnail images.

  As described above, the thumbnail regeneration determination table allows the thumbnail image to be regenerated as needed during image processing, leading to faster image processing.

  If it is determined in step S304 that the reproduction of thumbnails is image processing that is defined to be based on the range in which the effect is applied, the system control circuit 50 calculates the range in which the image processing effect is applied (step S305). After the calculation, the system control circuit 50 refers to the thumbnail regeneration determination table again based on the calculation result (step S306).

  In the thumbnail regeneration determination table, whether or not to regenerate thumbnails is defined based on the effect range for the processing determined to be unnecessary for thumbnail regeneration in the previous determination (step 304). For example, in the case of red-eye correction processing, the thumbnail regeneration determination table defines that thumbnail regeneration is unnecessary if the proportion of red eyes is less than 3% of the total. Therefore, for example, in the case of an image as shown in FIG. 5, it is determined that regeneration is unnecessary, and the thumbnail regeneration flag remains OFF after all. If the red-eye corrected image has a large correction range as in the image of FIG. 8, it is necessary to regenerate the thumbnail, and the thumbnail regeneration flag is turned on (step S307). FIG. 8 is a diagram illustrating an example of a red-eye correction execution menu when the correction range is large.

  Note that the threshold value of the effect range defined in the thumbnail regeneration determination table may be changed for each process, or the same value may be used for all processes. However, in this embodiment, the threshold value of the effect range is changed for each process.

  After the determination described above, the system control circuit 50 performs image processing on the main image (step S308). After the image processing is completed, the system control circuit 50 looks at the previous thumbnail regeneration flag (step S309), and applies the same image processing to the thumbnail image only when the flag is set to ON (step S310). When the processing for the thumbnail image is completed, the system control circuit 50 turns off the thumbnail regeneration flag (step S311) and ends the processing shown in FIG.

In the above, red eye correction has been described as an example in the regeneration of thumbnails in image processing.
In this embodiment, when image processing is performed, it is determined whether or not to regenerate thumbnails according to the processing content and the range covered by the processing. However, only one of them may be used as a determination criterion. 7 may be set freely by the user through a user interface displayed on the image display unit 28. The thumbnail regeneration determination table shown in FIG.

  In this embodiment, the thumbnail regeneration determination table determines whether or not to perform thumbnail regeneration after the user selects image processing. For example, instead of the table as shown in FIG. May be set manually. FIG. 9 is a diagram illustrating an example of a thumbnail regeneration setting menu.

Further, when displaying a thumbnail image that has not been regenerated after image processing, an icon 802 displays what image processing has been performed on the main image corresponding to the designated thumbnail image 801 as shown in FIG. May be. FIG. 10 is a diagram illustrating an example in which an icon 802 displays what kind of image processing has been performed on the main image corresponding to the thumbnail image 801.
By displaying the icon in this way, the user can immediately know what processing has been performed on the corresponding main image while viewing the thumbnail image, and as a result, the thumbnail image is regenerated. An effect equivalent to that obtained can be obtained.
