Focus adjustment device having restricting means for restricting a selecting action according to the degree of nearness of a distance measurement

摘要

A focus adjustment device arranged to measure distances at a plurality of points on a picture plane specified by an optical means to be focus- adjusted and to adjust focus of the optical means on the basis of the results of distance measurement includes: selecting circuitry for selecting information on the nearest of measured distances obtained at the plurality of points, and restricting circuitry for restricting a selecting action of the selecting circuitry according to the nearness degree of the nearest distance in relation to the focal length of the optical means, the position of the distance measuring point on the picture plane, etc.
