Abstract
PURPOSE: To make possible the controlling of the otimum exposure according to arbitrary photographing modes including the photographer's composition intention by time-series-selecting the set exposure information by way of registers according to the processing through a ROM and applying the same to an arithmetic circuit.
CONSTITUTION: For example, when a shutter-priority mode is selected, film sensitivity is set in a film sensitivity input means, the shutter second time in a set exposure time input means and the maximum and minimum aperture values, etc. by composition intention are set in maximum and minimum aperture value setting input means AMX, AMN. Programs are then sequentially read out from a ROM by the addresses corresponding to the stepwise advancing of a sequence control counter SCCO, etc. and according to the process controlling, select gates IDS are selected so that the programs are time-serially applied to an arithmetic circuit AC, whereby controlling of correct aperture or displaying that the correct exposure is out of the photographer's intended range, etc. is accomplished. The same holds true for manual, aperture-priority and program photographing modes, thus the optimum exposure controlling including the photographer's intention is accomplished.
