ABSTRACT:
An electronic read-only memory is provided for each photographic program whose input is connected to a resettable pulse counter which is actuatable step-by-step via a clock pulse generator and which memory delivers program signals predetermined by its program that correspond to the output signals of the pulse counter. The outputs of all read-only memories are connected to the component parts they control via a program selector circuit. A display matrix for displaying the content of the read-only memories is provided, which display matrix is connected at the output of the program selector circuit and whose display is synchronized by means of the clock pulse generator operating at a sufficiently high rate that the entire program can be observed at one time.
