description An analog-to-digital converter for a camera has a reference signal generating element, a measurement signal generating element, and pulse output means for generating pulses of pule durations corresponding respectively to signals from the generating elements. The generating elements are alternately selected to produce two pulse durations, and the ratio of these two durations is computed by pulse duration ratio computing means. Control information corresponding to the computed ratio is retrieved from memory means.
