Abstract
A light metering device incorporates a light dependent resistor as a light sensing element, a network including a plurality of circuit elements, and a selection mechanism for selectively connecting the light dependent resistor to one of the plurality of circuit elements in the network. The selection mechanism is controlled to set a voltage measured at an output terminal of the light dependent resistor within a predetermined threshold level. The light metering device can be readily incorporated in both photographic and electronic cameras.
