ABSTRACT:
A camera power supply system includes a controller that reduces power consumption by modifying the operation of the camera system clock circuit after the completion of each exposure taking sequence. The clock circuit operation is modified either by bypassing current drains, thereby reducing the accuracy of the clock circuit as well as its power consumption, or by reducing the frequency of the clock pulses produced by the system clock. Modifying the operation of the system clock in this way does not adversely affect operation of systems such as information displays, but does reduce power consumption. The clock circuit operation is restored at the beginning of an exposure sequence.
