. When a still image is being played, it is in an endless loop, so the process moves to step S4, and the screen display means 230 shows that the operation of Loop Count = 0 is a disk specification and the method for canceling the operation. Screen display to the user is performed on the display device 20.

Then, when it is determined that the still image without audio is not played back, or when it is determined that the Loop Count = 0 is not set, the process proceeds to step S7, and the auto pause determination unit 226 performs auto pause. It is determined whether or not the camera is in a pause. If it is determined that the camera is in an automatic pause, the automatic pause permanent waiting setting determination unit 227 determines whether the automatic pause is a Wait T.
It is determined whether or not ime = 0 (permanent waiting setting) (step S8). When the auto pause is Wait Time = 0, the process proceeds to step S4, where the screen display means 230
A screen display to the user indicating that the operation at Time = 0 is a disk specification and a method for canceling the operation is performed on the display device 20.

When it is determined that the auto pause is not in progress, or the auto pause is Wait Time = 0
If it is determined that it is not, the reproduction item waiting determination means 228 determines whether or not the reproduction item waiting determination means 228 is in a reproduction item waiting (waiting process to be performed after non-menu reproduction ends) (step S).
9) When waiting for a playback item, the play item permanent waiting setting determination means 2
29 determines whether or not the play item has Wait Time = 0 (permanent waiting setting) (
Step S10). When the play item is Wait Time = 0, step S
4, the screen display unit 230 performs screen display for the user indicating that the operation of Wait Time = 0 is a disk specification and a method for canceling the operation, on the display device 20.

If it is determined in step S1 that PBC playback is not being performed, if it is determined in step S9 that it is not waiting for a playback item, or if it is determined in step S10 that the play item is not Wait Time = 0, this processing ends. To do.

FIG. 5 is a diagram showing an example in which the play item is set to be in a permanent waiting state and the operation canceling method is displayed on the menu screen in the present embodiment.
