Abstract

PURPOSE:To perform good focusing by detecting the degree of deviation of the imaging planes owing to a pair of image sensors by means of sharp object images. CONSTITUTION:A pair of imaging optical systems which are constituted of lenses 111, 112, etc. disposed by leaving a fixed distance and at least >=2 rows of photosensitive picture element rows 14 arranged with photosensitive picture elements 13 in one direction are provided in the direction orthogonal to the row direction. A pair of image sensors 121, 122 which are so disposed that the imaging planes of a pair of the imaging optical systems and the rows 14 are parallel and that the rows are inclined by having a prescribed angle to the imaging planes as well as a displacement degree detecting means consisting of a signal processing circuit 18 detecting the degree of displacement when the image outputs of both coincide by comparing the image output signals outputted from a pair of the sensors 121, 122 are provided.
