DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments to which the invention is applied will be described in detail with reference to the accompanying drawings.
<First Embodiment>
FIG. 1 is a block diagram showing a configuration of an image display apparatus according to the first embodiment of the present invention.
In FIG. 1, 101 is a memory card control unit, 102 is a CPU (Central Processing Unit), 103 is a memory, 104 is a light receiving unit, 105 is a remote control device, 106 is an image decoding unit, 107 is a screen configuration unit, and 108 is display control. Reference numeral 109 denotes an image display unit. A memory card having a storage medium that can be randomly accessed can be connected to the memory card control unit 101.

FIG. 3 shows an example of an operation flow until a memory card is connected to the memory card control unit 101 in FIG. 1 and a plurality of thumbnail image data in the continuous shooting group is displayed on the image display unit 109.
In FIG. 1, a memory card controller 101 is connected to a memory card that groups and stores a plurality of image data shot by a digital camera having a continuous shooting mode, a digital camcorder, or the like (corresponding to step 301 in FIG. 3). To do).

  When the memory card control unit 101 in FIG. 1 detects that the memory card is connected by the user of the image display device in step 302 in FIG. 3, the connection detection information is transmitted to the CPU 102.

  In step 303 in FIG. 3, the CPU 102 in FIG. 1 receiving the connection detection information reads the continuous shooting group information stored in the memory card into the memory 103 via the memory card control unit 101.

  In step 304 in FIG. 3, the CPU 102 in FIG. 1 analyzes the read continuous shooting group information. Here, the number of continuous shooting groups existing in the memory card and the number of images for each continuous shooting group are analyzed.

  In step 305 in FIG. 3, data of one thumbnail image included in one continuous shooting group is read according to the analysis result of the previous step 304.

  In step 306 in FIG. 3, one thumbnail image data read in step 305 is sent to the image decoding unit 106 in FIG. 1, subjected to decoding processing such as JPEG decoding, and temporarily cached in the memory 103. Is done.

  In step 307 of FIG. 3, if there is unread thumbnail image data in the same group in accordance with the analysis result of the previous step 304, the process returns to step 305 to read the corresponding thumbnail image data. If there is no unread thumbnail image data in the same group, the process proceeds to step 308.

  In step 308 of FIG. 3, if there is an unread continuous shooting group in the memory card, the process proceeds to step 309. If there is no unread continuous shooting group in the memory card, the process proceeds to step 310. move on.

  In step 309 in FIG. 3, if the number of continuous shooting groups read as described above is 9 or more, the process proceeds to step 310. If the number of continuous shooting groups read as described above is less than 9, step 305 is executed. Return to, and read thumbnail images of other continuous shooting groups.

  Therefore, according to the above-described processing steps, the processing from step 303 to step 309 is performed until there is no continuous reading group not yet read in the memory card module or the number of the continuous shooting groups read is nine. Will repeat. In the present embodiment, the number of continuous shooting groups that can be read is 9, but this is not limited to this, and 6, 12 or any other number may be used as long as it is an optimal number for a screen display described later.

  In step 310 of FIG. 3, the thumbnail image data first taken in time in one continuous shooting group cached in the memory 103 of FIG. 1 is extracted. Thereafter, when the number of continuous shooting groups cached in the memory 103 is 9, in step 310 and 311 of FIG. 3, the thumbnail image data first taken in time in a total of nine continuous shooting groups is displayed. 1 from each memory 103 and sent to the screen composition unit 107. On the other hand, when the number of continuous shooting groups cached in the memory 103 is 8 or less, the thumbnail image data taken first from all the continuous shooting groups is read out, and then returned to the first continuous shooting group and shot. The thumbnail image data with the second order is read out. Then, the thumbnail image data with the second shooting order is sequentially read out from each continuous shooting group, and then the thumbnail image data with the third shooting order is read back again to the first continuous shooting group. Such processing is performed until the number of read thumbnail image data reaches nine.

  In step 312 of FIG. 3, the screen composition unit 107 of FIG. 1 composes display data for displaying a list of thumbnail image data of different continuous shooting groups from the plurality of thumbnail image data sent as described above, and performs display control. 3 and displayed on the image display unit 109 in step 313 of FIG. An example of the screen display is shown in FIG. In FIG. 4, in each of the nine continuous shooting groups, thumbnails of images first taken in time are displayed.

  After the display as described above, the CPU 102 in FIG. 1 displays the thumbnail image data taken second in time in each of the nine continuous shooting groups cached in the memory 103 at regular intervals, such as BitBLT. The image is sent to the screen composition unit 107 using the drawing means. The screen configuration unit 107 updates the sent thumbnail image data for each identical continuous shooting group, creates display data, and sends the display data to the display control unit 108. The display control unit 108 displays the sent display data on the image display unit 109. By repeating this operation with the third imaged data and the fourth imaged data in time, it is possible to simultaneously perform slide show reproduction for all the continuous shooting groups. FIG. 5 shows a transition image of the thumbnail image display of the continuous shooting group in the portion indicated by 41 in FIG.

  In the example of FIG. 5, the image shown by 51 is the first image taken in time in the continuous shooting group, the image shown by 52 is the image taken second in time, and so on. Is 53, 4 is 54, 5 is 55, 6 is 56, 7 is 57, 8 is 58, and 9 is 59. When all the display is completed in one continuous shooting group, Returning to the first 51, the slide show is reproduced from the beginning. The same applies to the continuous shooting groups indicated by 40 and 42 to 48 in FIG.

  According to the first embodiment described above, since thumbnail images of a plurality of continuous shooting groups are displayed as a slide show, thumbnail images of a plurality of continuous shooting groups can be efficiently and simultaneously listed on one screen. User convenience is improved.
