The width WA of the photosensing surface 14 and the width W0 of an arrangement period are fixed, while the width WB of the photosensing surface 16 and the width G of the gap 17 are varied in accordance with formulas. In the formulas, L0 denotes a distance between the minimum width position (a) and the maximum width position (b) of the photosensing surface 16, and L a distance from the position (a) to an arbitrary central position (x). According to this constitution, the photosensing substance 11 outputs a photocurrent IA corresponding to the brightness of a second image, irrespective of the displacement of the sensed image, while the photosensing substance 12 outputs a photocurrent IB corresponding to the displacement of the sensed image. By determining IB/IA, therefore, the displacement of the sensed image of which a variation in the brightness is canceled, i.e. an information on the distance to a subject, can be obtained.
