ABSTRACT:
A camera includes a measuring circuit for outputting data about an object to be photographed. A fuzzy computer receives an output from the measuring circuit as an input value, obtains a fitting degree of the input value with respect to a then-part membership function from an if-part membership function and the then-part membership function, both of which correspond to a plurality of rules representing a degree of influence of the input value on an optimal exposure value, obtains a center of gravity value from a plurality of fitting degrees corresponding to the rules, and obtains a determination value as an inference result. A photographic condition is determined by both the determination value from the fuzzy computer and an output from the measuring circuit.
