Abstract
The illustrated embodiment utilizes a series of pre-programmed read-only memories any one of which may be selected to control a photographic operating sequence. The program steps from the selected read-only memory are preferably sequentially selected by means of a pulse generator which successively actuates a sequence counter supplying the read-out address to each of the read-only memories. The outputs of all of the read-only memories are connected with the components of the photographic system to be controlled, a program selector determining which of the read-only memories is to be actually operative. A freely programmable memory is also present which is controlled by input keys so as to be programmable step by step by the operator under the control of the sequence counter which in this case is operated in a step mode. The keyboard has symbols representing the operations and parameters to be selected thereby, with provision for reviewing the operating sequence of any program without actually carrying out the photographic sequence.
