Abstract
A program control device for the photographic cycle is present, which contains an electronic read-only memory for each photographic program. A resettable pulse counter is actuated step-by-step by a clock pulse generator and controls the selected memory to deliver program signals predetermined by its program. The outputs of all read-only memories are connected to the component parts they control via a program selector circuit. A correction memory is controllable for the input of correction program elements and is connected in parallel to the read-only memories. A recognition memory controlled by the pulse counter is connected to the program selection circuit and the program steps to be corrected are storable therein, so that, upon reaching such a program step, the correction memory (60) supplies the program in place of the respectively selected read-only memory.
