Description

  The present invention relates to an image display technique in an imaging apparatus.

  Digital cameras are mainly equipped with an LCD display as an image playback device, and have the convenience of being able to immediately check a captured image. The captured images can be displayed one by one, and operations such as enlargement can be performed on each image, and information such as a histogram can be displayed simultaneously. It is also possible to display a desired image by displaying a very small number of thumbnails.

  However, it has been difficult to compare a plurality of images in detail, for example, by performing bracket shooting to select the best image. One of the reasons is that this type of conventional image reproducing apparatus is quite small and cannot be used for displaying multiple images and comparing the images. In recent years, relatively large LCD displays have been used for digital cameras as image playback devices, and the usefulness of multi-image display has increased.

  As an example of conventional multi-image display, there is known a series of image data that can be displayed and slid on a screen simultaneously with a plurality of image data that follow the image data (see Patent Document 1). If this method is used, images taken before and after can be viewed side by side, which can be roughly compared, and it is easy to select a desired image from a large number of images. However, even if this method is used, it is not easy to compare similar images in detail.

In addition, it is known that captured image data can be grouped based on the shooting date and time, and multiple images can be displayed for each group (see Patent Document 2). If this method is used, it becomes easy to organize a large number of images and select a desired image from them, but there is no advantage in comparing similar images. There are many other documents that feature multi-image display, but none of them disclose a technique that makes it possible to compare similar images in detail.

  Hereinafter, a characteristic configuration of the present embodiment in the reproduction mode will be described in detail.

  First, FIG. 2 shows a one-image display state in the normal reproduction mode. Here, when a multiple display instruction operation is performed, a multiple display state is set. FIG. 3 shows an image of a display device in a multiple display state. This multiple display instruction operation may be an operation of pressing or long-pressing a specific button provided on the operation unit 70 of the image processing apparatus 100, or a method of selecting from a menu screen of the image display unit 28.

  Further, here, in order to simplify the explanation, the case of displaying two images is shown, but the present invention is not limited to two images, and the number of display images may be selected.

  In addition, an instruction display for selecting an operation target image is shown below the display unit, but the operation target image selection unit is not limited to a toggle. For example, it may be designated with a cross button and selected / cancelled with a set button, or may be selected with a touch panel in a system having a touch panel.

  Here, as an example, the operation target image is selected by the set button toggle. However, when the set button is pressed once, the selected image is switched as shown in FIG. 4 to enter one image selection state. In this state, all image operations (enlarge and move) are performed. Etc.) is performed only on the selected image. When the set button is pressed again, the other image is selected as shown in FIG. This state is also a one-image selection state. When the set button is pressed again, the two-image selection state is entered. In this multiple image selection state, when the enlargement and display position moving operations are performed, the selected multiple images are operated simultaneously as shown in FIG. 6 (all the selected multiple images are simultaneously expanded and the display position moving operation is performed). ) When an operation for displaying the next image is performed again in the enlarged state, the next image is displayed while maintaining the enlargement magnification and the display position. In other words, the setting of the magnification and display position for the image that is already being displayed is applied to the next image.

  In the case where the enlargement operation, the display position movement operation, etc. are performed again in the multiple image selection state after performing the enlargement and display position movement in the single image selection state, the enlargement magnification and the display position of each of the selected multiple images are different. In the case of being present, an enlargement operation, a display position movement operation, and the like are added to the state immediately before the operation of each of the plurality of images. For example, when two images that have already been enlarged at the same magnification and double in the single image selection state are selected to perform multiple enlargement simultaneously, the images are doubled and quadrupled. If the limit of expansion or movement is reached, the operation is not reflected. When the vertical image and the horizontal image are displayed at the same time, the vertical image becomes vertical, and the operation is the same as that of the horizontal image. When the next image is displayed while maintaining the enlargement and display position, if the vertical and horizontal directions are different, an image in which the same position is enlarged from the coordinates is displayed.

  The system control circuit 50 can exchange the positions of the two images being selected with each other by an image position exchange instruction that is a selection operation from an operation button or menu arranged on the operation unit 70. Further, it is possible to display a histogram and a whiteout range of each image being displayed by an instruction that is a selection operation from an operation button or menu arranged on the operation unit 70.

  The system control circuit 50 can simultaneously delete one or more selected images from among a plurality of images being displayed. Conversely, it may be possible to simultaneously delete one or more images that are not selected for this operation. By a similar operation, it is possible to simultaneously protect one or more selected images among a plurality of images being displayed. Similarly, it is possible to designate one or a plurality of selected images as a print target image from among a plurality of images being displayed and perform direct printing by an external output device connected to the digital camera.

  The image display method and the display image operation method shown in the present embodiment are executed not only in the image playback mode of the digital camera but also in the multi-display instruction at the time of the REC review hold. Rec review is a function for automatically displaying image data taken immediately after shooting on the image display unit 28 for a certain period of time. Normally, an image stored in the image display memory 24 or the memory 30 is read immediately after shooting to display an image. Displayed on the unit 28. The REC review hold is a function that holds the REC review display state until the review hold release button is pressed by pressing the review hold instruction button arranged on the operation unit 70 during the REC review display period. is there.

  In the present embodiment, a plurality of similar images are displayed on the image display unit 28, and these can be compared simultaneously by enlarging or moving them. However, this is a comparison target displayed at the time of REC review hold. The multiple images are either bracket images in bracket shooting, all continuous images in continuous shooting, or images shot within a designated time in standard shooting. Each of the image groups may be displayed in a multi-display (multiple image display) at the same time, or may be displayed in multi-displays by a predetermined number.

It is determined whether or not the REC review hold is instructed while the REC review display is being performed (step S703). If the REC review hold is not instructed, the REC review display is terminated after a predetermined time has elapsed. (Step S707). If the REC review hold is instructed in step S703, the REC review display is continued as it is, and it is determined whether or not a multiple image display is instructed (step S704). If multiple image display is not instructed in step S704, the process waits until the REC review hold instruction is canceled in step S706, and REC review display is terminated. If multiple image display is instructed in step S704, the process advances to step S705 to display multiple images. Thereafter, if necessary, the user performs an image enlargement operation, an image movement operation, or the like as described in the above embodiment to confirm the image, and after the REC review hold instruction is released (Yes in step S706). The REC review display ends (step S707).

  Also, by designating a mode (multi-display mode) for displaying a plurality of images in advance during the REC review hold, the above image group is automatically displayed in multiple display during the REC review hold. FIG. 8 is a flowchart showing the operation at this time.

  First, when shooting is performed (step S801), immediately after that, REC review display for displaying the captured image data on the image display unit 28 is performed (step S802). It is determined whether or not the REC review hold is instructed while the REC review display is being performed (step S803). If the REC review hold is not instructed, the REC review display is terminated after a predetermined time has elapsed. (Step S806). If the REC review hold is instructed in step S803, the REC review display is continued and a plurality of images are displayed (step S804). Thereafter, if necessary, the user performs an image enlargement operation, an image movement operation, or the like as described in the above embodiment to confirm the image, and after the REC review hold instruction is released (Yes in step S805). The REC review display is terminated (step S807).
