When an image is played back on a liquid crystal cell, an auxiliary lamp is turned on. In this way, a displayed image can easily be confirmed. If an image frame forward switch is not turned on after the auxiliary lamp is turned on, the auxiliary lamp is turned off. In this way, unnecessary lighting of the auxiliary lamp can be prevented, and an amount of electric power consumed can be reduced.
