ABSTRACT:
A photographic camera having a photographic operating device including a focus detecting circuit, a shutter control circuit, a light measuring circuit and a light emission control circuit, an adjustment data memory for storing adjustment data based on functional characteristics of the respective circuits of the photographic operating device and an adjustment circuit for adjusting the respective circuits by using adjustment data read from the adjustment data memory. The adjustment data memory is consituted by an EEPROM for making it possible to conveniently and readily rewrite the adjustment data. The adjustment data is calculated from a linear function expression established between a design value and an actual value for avoiding trial-and-error preparatory operations for the adjustment.
