Abstract
A camera in accordance with the invention includes a display circuit that uses the decay voltage of a storage capacitor to determine the time interval during which an information display of the camera will be illuminated. When the storage capacitor decay voltage falls below a predetermined value, power to the information display is removed. The storage capacitor is used to power another camera system and therefore is not an additional component necessary for the display circuit alone.
