Abstract

PURPOSE: To correct the photometric value so that is may approach the illumination intensity of the film surface for actual lens stopping-down and photographing, by correcting plural photoelectric outputs for photometric operations according to the position of each region of the object field on a basis of set information of the photographic lens.
CONSTITUTION: Photometric outputs from photometric circuit 1 where photodetectors are arranged into a matrix are applied to adding circuits 711, 712... of correction operating circuit 7. Meanwhile, correction values, which are based on the photographic lens and correspond to respective region position of the object field corresponding to respective photoddtectors, are applied to these circuits 711... from correction value calculating circuit 8 on a basis of the opening stop value, the number of steps of stopping, and the focal length and the emission pupil length of the photographic lens which are set by setting circuit 5. Consequently, outputs of circuits 7 become values which are so corrected that they may approach the photometric illumination intensity corresponding to the actual film surface, and an accurate exposure value is operated and determined through matrix operating circuit 3.
