Examples of the type of event detected here include MENU, JUMP, +,-, and SET indicating that the button has been pressed, DIAL indicating that a dial change has occurred, and the like.

In step S6, a value obtained by adding the value indicating the current time and the constant value TOVAL to the variable TO is set.
Alternatively, if no input event is detected in step S5, the processing of steps S7 to S16 according to the variable ST designating the current state is performed. Steps S12 to S16
, The variable ST indicating the current playback operation state of the device and the variable F indicating whether or not automatic playback is being performed, according to the type of processing performed by the user.
The LAG is changed.

Thereafter, the current mode dial switch 6
It is determined whether or not the position of 0 is single or multi (step S17). If it is neither single nor multi, the process ends. On the other hand, if the current position of the mode dial switch 60 is single or multi,
It is determined whether or not the variable ST indicating the state has changed compared to before execution of the processing of steps 12 to S16 (step S18), and if so, an event indicating that the state has changed is issued (step S18). Step S19). The name of this event is hereafter referred to as NEW.

Then, the variable FLAG indicating whether or not the automatic reproduction is being performed is checked (step S20). If it is determined that the automatic reproduction is being performed, that is, if the variable FLAG is set to TRUE, the processing in the next step S21 is performed. Without returning to step S5.

On the other hand, if the variable FLAG is FALSE, the current time is compared with the value set when the previous event occurred (step S21). If the current time does not exceed that value, the process is repeated again. It returns to the process of step S5. On the other hand, if the current time has exceeded the set value, the process ends without returning to the process of step S5.

As described above, as long as no event for ending the main reproduction process occurs, steps S5 to S2 are performed.

With this processing, the state is changed to MENU after the end of the slide show. After the event NEW is issued by the main reproduction processing, the MENU processing is executed, and the menu is drawn.

Further, the event (EV) that has occurred is NO
NE, that is, if no operation is performed by the user, it is determined whether or not automatic reproduction is performed (step S83), and if not, no processing is performed and the processing is terminated. On the other hand, if the automatic reproduction has been performed in step S83, it is determined whether or not the time for reproducing the next image has been reached (step S84). If not, no processing is performed and the processing ends.

On the other hand, if the time for reproducing the next image has been reached, it is determined whether or not the automatic reproduction is currently interrupted (step S85). If the automatic reproduction is interrupted, no processing is performed. The processing ends without performing the processing. On the other hand, if the automatic reproduction has not been interrupted, it is determined whether or not the reproduction of the reproduction target image has been completed and the repeat setting has not been made (step S86). If the reproduction of the reproduction target image has been completed and no repeat setting has been made, the process branches to the slide show end processing (step S81). On the other hand, if the reproduction of the reproduction target image has not been completed, or if the repeat setting has been made, a screen to be displayed next is created (step S87), and the process ends.

The event (EV) that has occurred is +/-
If so, it is determined whether or not the automatic playback is being performed (step S74). If the automatic playback is being performed, the flag variable PAUSE for interrupting (pausing) the automatic playback is set to PAUS.
A value obtained by logically negating E is substituted, and the processing is terminated.

On the other hand, when automatic reproduction is not being performed, that is, + /
If manual reproduction is designated, step S8
An end check similar to that of No. 6 is performed (step S90). If it is determined to end, the process branches to the slide show end process (step S81), similarly to step S86. On the other hand, if not, a screen to be displayed next is created (step S91), and the process ends.

Further, the event (EV) that occurred has a DI
If AL. The current dial state is determined (step S92). The current dial mode switch 60 is set to S
If it is changed to single or Multi, FALSE is set to the variable FLAG (step S93),
After the setting, an end process is performed (step S94). Then, the reproduction state according to the dial mode is set to a variable ST (step S95). On the other hand, in step S92, S
If it is not single or Multi, the process ends without doing anything. In this case, as described above, the position of the dial mode switch 60 is checked in step S17 of the main reproduction process, and the main reproduction process ends. .
