Abstract
A distance detector has an optical system for forming a subject image, a distance measurement sensor, and a distance calculating circuit for calculating a distance to a subject based on an output from the distance measurement sensor. The distance measurement sensor has a plurality of line sensors disposed substantially on an imaging plane of the optical system. Each of the plurality of line sensors has a light sensing array composed of a plurality of pixels for sensing the subject image and a processor array for processing outputs of the light sensing array. The plurality of line sensors are arranged so as to be axisymmetrical with respect to a virtual line, with the light sensing arrays arranged closer to the virtual line than the processor arrays.
