ABSTRACT:
A photographic camera of the multiple spot photometry type is provided which functions to receive and store information representing the brightness of an object being photographed at desired spots to be determined. A microcomputer applies an arithmetic operation on such information for exposure control or display. When the number of information items representing the brightness of the object exceeds a given number, the latest information is substituted for the oldest information.
