ABSTRACT:
An indication control unit for an electronically controlled camera. The indication control unit includes a display for indicating photographic information; electrical power supply for the indicator unit; a film presence detecting device; a mechanism for switching the camera between an operable, picture taking state and an inoperable, non-picture taking state; and a mechanism for disabling the electrical power supply if the camera is in the inoperable, non-picture taking state and the film presence detecting device fails to detect film in the camera. With the present invention, the amount of electrical power that is consumed by the indication control unit, which can include a liquid crystal display, for example, is minimized.
