It doesn't matter. The search / skip key is a switch configured to function as a search key when pressed once (short press) and as a skip key when pressed for a predetermined time (long press). Although each key button is arranged in a lump in FIG. 2, it may actually be configured such that each key button is individually arranged in place.
[0011]
Next, the operation in the interval playback mode (slide show) in the image playback apparatus of the present invention will be described.
[0012]
When the user presses the slide show execution key, the slide show is started. If the slide show execution key is pressed while the slide show is being executed, the slide show is stopped.
[0013]
The image data read from the memory card 20 is decompressed by the compression / decompression circuit 16, applied to the monitor 14 via the image processing circuit 12, and displayed as an image.
[0014]
In the slide show, a plurality of image data stored from the memory card 20 are read at regular time intervals and displayed on the screen of the monitor 14 according to rules such as file number order or category.
[0015]
When the image advance key (+ or-) is pressed during the slide show, the image that is being displayed at that timing can be set to display disabled (that is, playback disabled). When the slide show is continuously repeated or when the slide show is executed again, this image is not displayed. The display / non-display setting information for each image can be stored in the memory card 20 as a slide show display setting pattern program using the setting key. It is possible to create multiple programs with different contents. FIG. 3 shows a display pattern setting example. Note that the user can also set a time interval when these image display patterns are actually displayed in a slide show. In this embodiment, an example in which the time is set to 5 seconds will be described. However, this can be set at an arbitrary time, and time interval information can also be stored as a program.
[0016]
When a slide show is executed, a desired slide show display setting pattern can be selected by a read key, and a program selected from the memory card 20 can be read and set. Thereafter, the slide show is executed according to the read display pattern.
[0017]
FIG. 4 shows an operation flowchart of the system control circuit 22. With reference to FIG. 4, the operation of the slide show in the present embodiment will be described.
[0018]
The number of images stored in the memory card 20 is acquired (S1). The slide show execution / stop switch is monitored (S2) and waits until there is an execution request.
[0019]
When there is an execution request (S2), it is confirmed whether or not there is a request for reading the set display pattern (S3). If there is a read request (S3), a display pattern is selected and read (S4). If there is a request to save the currently set display pattern (S5), the currently set display pattern is saved (S6). By reading the stored display pattern again, it can be set as a slide show display pattern. The storage destination of the display pattern is the memory card 20. Thereby, the display pattern of the image to be displayed can be recorded on the same recording medium.
[0020]
The system control circuit 22 reads image data to be displayed next from the memory card 20 via the memory card interface 18. The read image is not yet displayed at this point. The system control circuit 22 checks whether display of the image read from the memory card 20 is permitted (S7). When the display is not permitted (reproduction prohibition is set) (S7), the process returns to step S2 through the selection process (S13) of the image to be displayed next.
[0021]
When the display is permitted (S7), the image data read from the memory card 22 is transferred to the compression / decompression circuit 16 and decompressed. The expanded image data is applied to the monitor 14 via the image processing circuit 12 and displayed as an image (S8). This image continues to be displayed until step S7 is executed again. A timer for 5 seconds is set (S9). Wait for 5 seconds (S12).
[0022]
During the execution of the 5-second timer, the displayed image can be set to be non-displayable by the image advance key (S10), thereby updating the display pattern (S11). Without waiting for the elapse of 5 seconds, the process proceeds to a process for selecting an image to be displayed next (S13).
[0023]
(Second embodiment)
FIG. 5 shows another flowchart of the system control circuit 22. Use the image skip key instead of the image advance key. When the image skip key is pressed once, the slide show simply shifts to the next image, and when the image skip key is pressed for a long time, a command for setting display disabled (reproduction prohibited) is issued in the interval playback mode.
[0024]
The number of images stored in the memory card 20 is acquired (S1). The slide show execution / stop switch is monitored (S2) and waits until there is an execution request.
[0025]
When there is an execution request (S2), it is confirmed whether or not there is a request for reading the set display pattern (S3). If there is a read request (S3), a display pattern is selected and read (S4). If there is a request to save the currently set display pattern (S5), the currently set display pattern is saved (S6). By reading the stored display pattern again, it can be set as a slide show display pattern. The storage destination of the display pattern is the memory card 20. Thereby, the display pattern of the image to be displayed can be recorded on the same recording medium.
[0026]
The system control circuit 22 reads image data to be displayed next from the memory card 20 via the memory card interface 18. The read image is not yet displayed at this point. The system control circuit 22 checks whether display of the image read from the memory card 20 is permitted (S7). When the display is not permitted (reproduction prohibition is set) (S7), the process returns to step S2 through the selection process (S13) of the image to be displayed next.
[0027]
When the display is permitted (S7), the image data read from the memory card 22 is transferred to the compression / decompression circuit 16 and decompressed. The expanded image data is applied to the monitor 14 via the image processing circuit 12 and displayed as an image (S8). This image continues to be displayed until step S7 is executed again. A timer for 5 seconds is set (S9). Wait for 5 seconds (S12).
[0028]
During the execution of the 5-second timer, the displayed image can be set to be undisplayable by the image skip key (S14), and the display pattern is updated (S11). Without waiting for the elapse of 5 seconds, the process proceeds to a process for selecting an image to be displayed next (S13).
[0029]
(Third embodiment)
FIG. 6 shows a third flowchart of the system control circuit 22. Use the image display key instead of the image advance key or skip key. The image display key is a switch for switching the display mode (normal image display, shooting information display, histogram display, etc.) for each image in a normal reproduction state.
[0030]
The number of images stored in the memory card 20 is acquired (S1). The slide show execution / stop switch is monitored (S2) and waits until there is an execution request.
[0031]
When there is an execution request (S2), it is confirmed whether or not there is a request for reading the set display pattern (S3). If there is a read request (S3), a display pattern is selected and read (S4). If there is a request to save the currently set display pattern (S5), the currently set display pattern is saved (S6). By reading the stored display pattern again, it can be set as a slide show display pattern. The storage destination of the display pattern is the memory card 20. Thereby, the display pattern of the image to be displayed can be recorded on the same recording medium.
[0032]
The system control circuit 22 reads image data to be displayed next from the memory card 20 via the memory card interface 18. The read image is not yet displayed at this point. The system control circuit 22 checks whether display of the image read from the memory card 20 is permitted (S7). When the display is not permitted (reproduction prohibition is set) (S7), the process returns to step S2 through the selection process (S13) of the image to be displayed next.
[0033]
When the display is permitted (S7), the image data read from the memory card 22 is transferred to the compression / decompression circuit 16 and decompressed. The expanded image data is applied to the monitor 14 via the image processing circuit 12 and displayed as an image (S8). This image continues to be displayed until step S7 is executed again. A timer for 5 seconds is set (S9). Wait for 5 seconds (S12).
