Abstract

PURPOSE:To display clearly a part outside the film latitude, by subjecting a photographic image to photometry divisionally and comparing the luminance value of a part having a designated intermediate density with each luminance value of divisional parts. CONSTITUTION:Outputs of photometric circuits M1-M6 are subjected to A-D conversion and are stored in registers RE1-RE6. The film latitude is stored in a reading circuit 3, and object luminances of upper and lower limits of the latitude are operated in circuits 7 and 9 on a basis of contents of the register corresponding to a part having an intermediate density designated by a circuit 5. Photometric data in respective parts stored in registers RE2-RE6 are compared with upper and lower limit values of circuits 7 and 9; and if a part is outside the latitude, the output of a corresponding OR circuit becomes H-level, and the photometric part outside the latitude is displayed on a warning display part 13.
