Abstract

PURPOSE:To discriminate both a preset information display part and a calculation information display part without providing a symbol display part, etc., specially, by distinguishing the driving signal form between said parts in an AE camera. CONSTITUTION:The information from a photometric element 1, a shutter speed 6, an aperture 7 and others are inputted to an arithmetic circuit 3, whose output information is inputted to shutter and aperture control circuits 10 and 12 through amplifiers 9 and 11, and also inputted to comparators 13 and 14. Pulse signals from a generator 16 to gate circuits 17, 18 through an AD converter 15 are counted at parts 21, 22 until coincidence signals are outputted from the comparators 13, 14, and after apex values are expanded to actual numerals by decoders 20 and 23, an aperture value and a shutter speed are displayed on display devices 19 and 24. Switching modes change over switches S3, S4, S5, and S6, and for a manually set value, a resistance (R1 or R2) is short-circuited to increase display luminance, thus discriminating between a preset value and an arithmetic value.
