(C) When the reduction button 307 is pressed in the enlarged display 2 state, (b) the enlarged display 1 is displayed.

  3 and 4 are process flows according to the present embodiment.

  When the user of the image processing apparatus 100 sets the mode dial 61 to the playback mode and presses the power ON / OFF button 60, the system control unit 50 initializes flags, control variables, and the like (S101) and is recorded on the recording medium 200. The last image among the existing images is searched and acquired (S102). If the directory structure of the images recorded on the recording medium 200 is as shown in FIG. 5, IMG_9803.JPG under the 998GANON directory having the largest image number is acquired.

  Next, the system control unit 50 displays the last image IMG_9803.JPG on the display unit 54 (S103), and starts a directory search (S104). Searching the directory changes what kind of directory exists, how many image files in total, how many moving image files exist, in which directory moving image files are stored, and the shooting date and time Search for file information such as where the image is.

  After starting the directory search (S104), the system control unit 50 periodically checks whether the button has been pressed (S105). The period for periodically checking may be any period. For example, it may be performed at intervals of 150 msec. If it is detected in S105 that the button has been pressed, the process proceeds to a button pressing process in S106, and processing is performed in accordance with the pressed button. The button pressing process in S106 will be described later with reference to FIG.

  Next, the system control unit 50 proceeds to S107. In S107, it is determined whether or not the directory search is completed. If not completed, the process returns to S105. On the other hand, if the directory search is completed in S107, the total number of images display process in S108 is performed. Since the total number of images cannot be acquired until the directory search process is completed, the reproduction image number and the total number of images are not displayed as shown in FIG. 12 when information is displayed. For this reason, after the directory search process is completed, the total number of images display process in S108 is performed, and the same display as that shown in FIG.

  Next, the system control unit 50 proceeds to the normal playback processing state of S109 and performs a normal playback operation. In a normal reproduction operation, all operations such as menu display, information display ON / OFF switching, deletion, search, index reproduction, and enlargement / reduction can be performed.

  FIG. 4 is a detailed process flow of the button pressing process in S106 in FIG.

  The system control unit 50 determines the type of the pressed button (S201), and if the menu button 301, the delete button 304, the search button 305, or the index playback button 306 is reached, the process proceeds to S202 and “processing” for 2 seconds. Is displayed. FIG. 13 is an example of a screen displaying “processing”. “Processing” is performed to notify the user of the image processing apparatus 100 that the button operation is not accepted.

  If the system control unit 50 determines in S201 that the power ON / OFF button 60 has been pressed, the system control unit 50 performs an end process of the image processing apparatus and turns off the power (S203).

  If the system control unit 50 determines in S201 that the reduction button 307 or the enlargement button 308 has been pressed, the system control unit 50 performs enlargement / reduction processing of the currently displayed image (S204). The enlargement / reduction process is as described above with reference to FIG.

  If the system control unit 50 determines in S201 that the frame advance button of the left button 309 and the right button 310 has been pressed, it performs a frame advance operation (S205 to S208). The system control unit 50 temporarily stops the directory search started in S104 (S205), and stores in the memory 30 information such as how far the search has been performed and how many images have been searched. Next, the system control unit 50 searches for an image to be displayed by frame advance (S206), and displays the searched image (S207). For example, if the directory structure of the image file recorded on the recording medium 200 is in the state shown in FIG. 5 and IMG_9802.JPG is currently displayed on the display unit 54, the left button 309 is pressed. IMG_9801.JPG is displayed, and when the right button 310 is pressed, an image file of IMG_9803.JPG is displayed on the display unit 54. Next, the system control unit 50 restarts the directory search process based on the information held in the memory 30 when the directory search is temporarily stopped in S205 (S208).

  If the system control unit 50 determines in S201 that the easy direct button has been pressed, it transfers the currently displayed image to the PC or printer. The system control unit 50 determines the connected device through the communication unit 110, and transfers the image displayed on the display unit 54 to the connected device (S210).

  If it is determined in S201 that the information display ON / OFF button has been pressed, the system control unit 50 performs information display ON / OFF switching processing (S209). The information display ON / OFF processing is as described above with reference to FIG. However, when the information display is ON, since the total number of images cannot be acquired unless the directory search is completed, only the display of the reproduction image number / total number of images is not performed as shown in FIG.

  As described above, according to the present embodiment, it is possible to reduce the time required until an operation can be accepted after the start of reproduction. Before searching for all directories and / or files, it is possible to perform frame advance, enlargement / reduction display, information display ON / OFF switching, power OFF, and image transfer. On the other hand, an operation that causes a change in the directory structure such as deletion processing or addition of a voice memo, and index reproduction that displays many images at one time are not accepted. When an operation that cannot be accepted is performed, it is possible to notify the user of the image processing apparatus by performing a display indicating that the operation cannot be accepted.

  In this embodiment, file deletion and voice memo are given as examples of the directory structure change. For example, an operation that causes a file copy, move, new creation, etc. is also an operation that causes a directory structure change to occur. Of course, the configuration may be such that no operation is accepted until all directory searches are completed.

In this embodiment, the search button 305 is provided. However, for example, the upper button 311 in FIG. 2 may be used also as the search button.
When the menu or the like is not being displayed as in the display example of FIG. 7 (that is, during the reproduction and display of an image), if the upper button 311 is pressed, the process proceeds to search processing, and FIG. The 10 jump screen is displayed. In the state of FIG. 9A, by further pressing the up and down buttons (311, 312), other search processing, for example, 100-sheet jump, moving image jump, date jump, etc. can be selected. Of course, not only the upper button but also any button can be configured to be used as a search button.
As described above, by using an existing button, for example, an upper button, the number of operation members can be reduced and the image processing apparatus 100 can be downsized.

  In the present embodiment, a computer-readable recording medium (or storage medium) that records a program code of software that implements the functions of the above-described embodiments is supplied to a system or apparatus, and the computer (or CPU) of the system or apparatus Or MPU) can read out and execute the program code stored in the recording medium. In this case, the program code itself read from the recording medium realizes the functions of the above-described embodiment, and the recording medium recording the program code constitutes the present invention. Further, by executing the program code read by the computer, not only the functions of the above-described embodiments are realized, but also an operating system (OS) running on the computer based on the instruction of the program code.
