Abstract

PURPOSE: To make possible the photographing of the modes corresponding to the photographer's selection such as manual, shutter-priority, aperture-priority and programmed photographings by performing micro-processing according to the programs of an ROM and controlling the camera.
CONSTITUTION: For example, when an ROM is addressed by a sequence control counter SCCO, the required commands, operands, etc. are generated from an instruction decoder ID via instruction register IR and the required operations are done. At the same time, the ROM is further addressed by the jump instruction from the register IR and the processing by the operations, etc. according to the jump shift is accomplished by the programs being read out from the ROM. The camera is then so controlled that photographings such as manual, shutter-priority, aperture- priority and fully automatic program modes are accomplished according to the photographer's selection. The controlling of timer photographing is also similarly accomplished.
