ABSTRACT:
A rear light condition detecting device for a camera is arranged to measure distances to a plurality of parts appearing within a taking picture plane on the assumption that an object located nearby is the main object to be photographed or that a light source such as the sun is among faraway objects. The device determines the object to be in a rear-light or counter-light condition in cases where the luminance of the nearby object is extremely lower than other objects or that of a faraway object is extremely higher than other objects.
