ABSTRACT:
A focusing system receives object light by a light receiving device having an array of light receiving elements. An amount of defocus or an object distance can be detected in accordance with the output of the light receiving device. The light receiver includes at least three spaced light receivers. A controller controls the quantity of light received by each of the light receivers such that each of the light receivers is either independently controlled, or a pair of outermost light receivers are controlled simultaneously.
