Abstract

PURPOSE: To reduce the effect of camera-shake by determining the shutter second time based on luminance which is not corrected by the full-aperture F value of the lens without making actual stopping-down at the time when the aperture gives the full-aperture side according to ranks rather than the full-aperture F value of the lens.
CONSTITUTION: A decoder circuit DCF which has received the signal of giving aperture value by a decoder circuit DEC compares the digital full-aperture F value information from a full-aperture F value digital switch F0D and the signal from the decoder circuit DEC, decides whether the aperture according to ranks is on the open side than the full-aperture F value of the lens or not and when it is on the full- aperture side, said circuit interrupts the inputting of the digital full-aperture F value informatin to a digital operator D0. Along with this, the decoder circuit DEC changes over from the full-aperture photographic mode corresponding to ranks to stopping-down photometric mode and outputs the shutter second time signal corresponding to the digital light value itself to a shutter control circuit SC.
