Abstract

PURPOSE:To always secure the correct exposure, by selecting the photometric output that ensures the exposure indicated by an indicating circuit in place of the photometric output indicated by a sorting circuit in case the overexposure or underexposure is indicated by manual setting operation. CONSTITUTION:A proper photometric output generating circuit 14 consists of photometric output generating circuits 11, 12 and 13 which receive the output of a photometric circuit 10 that divides a view field into plural regions for the photometric purpose and generate the photometric outputs of the high luminance value, the mean value and the low luminance value, respectively. One of plural photometric outputs is selected by selectively actuating gate circuits 15-17 through a selecting circuit 19 in accordance with the sorting output of a sorting circuit 18. When a shift is desired for the luminance value in place of the photometric output indicated by the sorting output, a setting means 25 or 26 is operated to shift the luminance value at the high or low luminance level.
