A brightness detecting device for an automatic exposure camera and a method of detecting brightness in an automatic exposure camera

摘要

An exposure value determination system which measures the light reflected off an object whose image is to be recorded when a first step release switch S1 is activated. The image of the object is recorded at a calculated exposure value when a second step release switch S2 is activated. If the time between the activation of the first step release switch and the second step release switch exceeds a predetermined time limit, an exposure value determination circuit measures the light a second time and calculates a new exposure value. If the predetermined time is again exceeded before the second step release switch is activated, the exposure value determination circuit will measure the light again and calculate a new exposure value.
