EXPOSURE CORRECTOR

摘要

PURPOSE:To decrease the luminance difference between a main subject and an auxiliary subject by shifting the exposure value of exposure control to the under side of the prescribed value when the aperture value determined by the exposure control is larger than the value required for stroboscopic photography and emitting the stroboscopic flash in the stage of the aperture value corresponding to the shifted value. CONSTITUTION:A comparator circuit 205 is inputted with the signal to indicate the aperture value of an exposure control circuit 203 and the signal to indicate the aperture value of a flashmatic circuit 204 and outputs a signal when the aperture value determined by the circuit 203 is larger. An exposure correcting means 206 permits the signal indicating the rear light condition from a means 208 for detecting the rear light when said signal is sent and shifts the exposure value sent from the circuit 203 toward the smaller value (under side). This circuit outputs the signal to close a shutter to an AE magnet AEMG and the signal to emit the stroboscopic flash to a stroboscope circuit 207 to close the shutter and to emit the stroboscopic flash when the shutter opens and the shifted exposure value is attained.
