Abstract

PURPOSE: To make possible the exposure which reflects the photographer's intention by also displaying the exposure information corresponding to the difference between the photometric output of subject plural regions and the measuring output through photographic lens aperture.
CONSTITUTION: The outputs corresponding to the photometry of the plural regions of the subject are generated by the plural photoelectric elements of a photometric circuit 100 and are made to the photometric output P6 of the APEX display value which determines the exposure of entire part of the image plane at the time of aperture priority or shutter priority by a processing circuit 101. The correct aperture value and correct shutter second time are displayed in the 2nd display circuit 107 by way of an APEX subtraction circuit 104 according to the shutter second time and aperture setting in an information setting circuit 105. Similarly, the difference between the APEX photometric value P1 of the central part or the like of the subject divided to plural regions and the photometric value P6 is detected by a differential circuit 102 and whether exposure is correct or not for the center or the like of the image plane is displayed in the 1st display circuit 103, thus the photographing by the exposure reflecting the photographer's intensiton may be accomplished.
