In case the camera is identified to be in the reproduction mode, the sequence proceeds to a step S 903 for executing a process in the reproduction mode. In the reproduction mode, there can be executed, for example, a process of switching the displayed image 1050 on the display unit 105 by the depression of arrow keys 1006 , 1007 shown in FIG. 10. Also the mode can be switched by a mode switching switch 1001 shown in FIG. 1.
