<p>The illumination control for a photographic camera has an A/D convertor for the light measuring device. A store is included for the convertor output signal storage, and a code convertor for the store output signal conversion into a value suitable for control of an exposure control device such as a shutter or diaphragm. It has a one-shot circuit (3) between the A/D convertor (2) and the store (4). It allows the convertor (2) output signal to reach the store (4) only when the one-shot circuit (3) output signal is high.</p> |
