Abstract
PURPOSE: To accomplish the focus adjustment in a satisfactory manner either under a condition out of focus or under a condition in teh vicinity of focus by roughly focusing in response with the brightness signals of a group of light receiving elements widely spaced from one another and by finely focusing in response to the signals of a group of light receiving elements narrowly spaced from one another.
