ABSTRACT:
Disclosed is a focus adjustment information forming device of the kind arranged to measure distances at a plurality of distance measuring areas on a picture plane specified by optical means which has its focal point being adjusted and to form information on adjustment of the focal point, the plurality of distance measuring areas including a center distance area located approximately in the center of the picture plane. The device comprises first priority means for giving priority to a measured distance value which represents the nearest distance among measured distance values obtained from the distance measuring areas; a second priority means for giving priority to the measured distance value obtained from the center distance measuring area according to its relations to the measured distance values of other distance measuring areas when one of the measured distance values of the distance measuring areas other than the center distance measuring area represents the nearest distance; and focus adjustment information forming means for forming information on adjustment of the focal point of the optical means on the basis of outputs of the first and second priority means.
