Abstract
PURPOSE: To make possible photographing under adequate exposure conditions by displaying the photometric value by either of photometric system as a central value and displaying the degree of deviation of other photometric value in both exposure value display systems of mean photometry and spot photometry.
CONSTITUTION: The outputs of a photo detector PD1 for mean photometry and a photo detector PD2 for spot photometry are fetched out time divisionally by FET1 and FET2. To display the shutter speed based on, e.g., mean photometric value as digital number and display spot photometric value stepwise, various switches are set as illustrated. The mean photometric value is displayed in the number of shutter speeds on the right center of a finder 17 by a display part 13 and the spot photometric value is displayed as stepwise display of dot display elements 16a thru 16f, 16a' thru 16f' on the right of the finder by a subtractor 14, decoder 15 and display circuit 16.
