ABSTRACT:
A metering device of a camera comprises a first photoelectric device provided with a light-receiving surface divided into a plurality of light-receiving portions each having a predetermined configuration, a second photoelectric device provided with a light-receiving surface divided into a plurality of light-receiving portions having configurations corresponding to the plurality of light-receiving portions of the first photoelectric device, and optical means for forming an object field image on the light-receiving surfaces of the first and second photoelectric devices so that metering areas metered by the light-receiving surfaces of the first and second photoelectric devices partly overlap each other on a phototaking picture and that the entire phototaking picture is substantially covered by the metering areas. The photoelectric devices are disposed so that the metering area, on the phototaking picture, of each of the light-receiving portions of the light-receiving surface of the first photoelectric device and the metering area, on the phototaking picture, of each of the light-receiving portions of the light-receiving surface of the second photoelectric device corresponding to the light-receiving portions of the first photoelectric device are substantially symmetrical with respect to a bisector of the phototaking picture.
