Abstract
A self-timer operation informing device, particularly one having an auditory and a visual display device is disclosed. In the case of such information device, since both display devices are always driven in order to carry out the display operation, a problem exists in that the power consumption for the self-timer operation display is large. On the other hand, since it is difficult to confirm the display state by the visual display when the brightness is high, in such cases the auditory display is significant. In other words, the visual display does not have significance under high brightness conditions. A self-timer operation informing device, therefore, selects the driving of the visual or the auditory display device in accordance with the brightness information so as to prevent unnecessary display in order to save the power consumption.
