  The case where the first embodiment of the present invention is applied to an image reproducing apparatus will be described below with reference to FIGS. 1 (A), 1 (B), 1 (C), 3 and 4.

  The overall image of FIG. 1A will be described with reference to a flowchart. In S100, the camera starts playback and enters the playback mode. When the playback mode is entered, the connection of the external connection cable is detected in S101. Then, 100 sheets are played back in S102. This mode will be described in detail with reference to FIG. When this 100-sheet playback is performed, a large number of images are displayed on the external connection screen. In this state, the external connection cable is disconnected in S103, and the image playback apparatus detects the insertion / extraction. When the external connection is canceled in S103, the notification of the resolution of the next connection destination display device is received in S104. In S105, it is determined whether the resolution notification result is the same as the current resolution. If the resolution notification result is the same, in S106, no image processing is performed, and finally, the reproduction ends in S115.

  If the current resolution notification is not the same as the resolution of the next connected display device in S105 and the current resolution notification is larger than the resolution of the next connected display device in S107, if the result is smaller, in S108 Play 100 pictures. This mode will be described in detail with reference to FIG. Finally, the reproduction ends in S115.

  Also, in S105 and S107, when it is determined that the current resolution notification is larger than the resolution of the next connection destination display device, the resolution of the next connection destination display device is set in a different area from the memory area displayed in S109. The resize is performed on the entire memory area where a plurality of images are drawn. In S110, the entire memory area resized in S109 is displayed.

The outline of S110 and S109 will be described with reference to FIG.
As seen from the user, when a request is made to change the memory area of S400 to a smaller resolution in S401, the memory area of S402 is resized and displayed on the entire memory. At this time, the operation of the single image that rereads the image is not performed.

  Details from S400 until final display S402 is output will be described with reference to the data flow diagram of FIG.

  In explaining this data flow diagram, there will be three memory areas, a display memory, a draft memory, and a save memory.

  The display memory is the currently displayed memory. If an operation is performed on this memory, an image being written can be seen, so the currently displayed memory is not operated.

  The draft memory is a preparation memory before drawing. Display is performed by writing what is to be drawn in this memory area and replacing it with the display memory.

  The save memory is a second draft memory. Since only one draft memory is used, it is used only when it is insufficient, so it is a memory that is not normally used.

  First, the entire memory is copied from the S500 display memory to the S502 save memory, and the S500 display memory is initialized to black. At this time, it is assumed that the draft memory of S501 is initialized in black. This prevents an unintended image from being displayed if the display of the device after resolution switching is too early. The completion state of this work is the display memory in S503, the draft memory in S504, and the save memory in S505.

  As soon as this processing is completed, the resizing process is performed on the save memory in S505, and the drawing is performed on the draft memory in S504. At this time, the display memory in S503 remains black by the initialization. The completion state of this work is the display memory of S506, the draft memory of S507, and the save memory of S508.

Then, the draft memory in S507 is replaced with the display memory in S506, and the draft area after the saving area in S508 is replaced, substantially the display memory in S506. The completion state of this work is the display memory of S509, the draft memory of S510, and the save memory of S511.
Thereby, the resized image is displayed.

  As for the drawing range, the resolution of the display device changes with the size of the memory, so the view from the user is S402.

  Thereafter, in S111, one of 100 images is played back. This mode will be described in detail with reference to FIG. As soon as it is completed, the one drawn in S112 is replaced with the displayed one. This is a measure for making the image quality better because the image quality deteriorates because the image is resized in S110 after being resized before the external connection cable is cut with respect to the image.

  Each time this is played back in S113, and every time the display to be replaced in S112 is finished, it is confirmed whether or not 100 pictures have been played back. As a result, if 100 pictures have been played back, the display ends in S115.

  If 100 images have not been played back in S113, it is checked in S114 whether all the images on the card have been processed. If all images in the card have been processed, Playback ends, but if not, the process returns to S111 and one sheet is played again.

Details of the reproduction of 100 images in FIG. 1B will be described using a flowchart.
First, playback of 100 images is started in S200. Next, in S201, reproduction of one of 100 images is started. This mode will be described in detail with reference to FIG.
Each time playback of one image is completed in S201, it is checked in S202 whether playback of 100 images has been completed. As a result, if playback of 100 images is completed, display ends in S204.

  If 100 images have not been played back in S202, it is checked in S203 whether all the images on the card have been processed. If all images in the card have been processed, Playback ends, but if not, the process returns to S201 to play back one sheet again.

  Details of reproduction of one image in FIG. 1C will be described using a flowchart. In S300, playback of one of 100 images is started. In S301, the file information is read from the recording medium, and it is confirmed whether the file is broken. If the image is broken in S301, a predetermined image, for example, an image drawn in advance in S302 is drawn, and the reproduction of one of 100 images ends in S308. If it is not broken, the address of the image body, the image aspect ratio, the rotation information, the size and position to be displayed are designated in S303, the JPEG header analysis is performed in S304, and the information necessary for JPEG decoding is acquired. Next, JPEG decoding is performed in S305, resizing processing is performed in S306, rotation processing is performed in S307, and reproduction of one of 100 images is completed in S308.

  Although the invention is completed with the above-described FIGS. 1A, 1B, and 1C, another form may be adopted with respect to FIG.

  For example, if the current resolution notification is not the same as the resolution of the next connection destination display device in S105, and if it is determined in S107 that the current resolution notification is smaller than the resolution of the next connection destination display device, it is determined that the current resolution notification is smaller. In FIG. 5, all image processing must be executed from image reading. In order to prevent this, a rough image may be used. Therefore, it is possible to enlarge the entire memory area and display the entire image as an image.

Further, if the current resolution notification is not the same as the resolution of the next connected display device in S105, all image processing is executed from image reading in S108, or control for displaying a resized image for the entire memory in S109 and thereafter. You have to do it.
However, if the difference in resolution is not significant, specifically when the resolution is 704 * 480 or 640 * 480 compared to 720 * 480, the entire memory area is brought to the center in order to shorten the drawing time. It is also possible to take the method of displaying as it is.

  According to the present embodiment, it is possible to significantly reduce the time until display after the external connection is released.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
