发明名称 Focus detection apparatus
摘要 Focus detection apparatus employs a plurality of focus detection areas, particularly cross type focus detection areas having two strip type focus detection areas which intersect at right angles in a photographing image plane. Embodiments of the invention make use of focus detection areas that vary in location, arrangement, orientation, alignment, and length. Photoelectric converters employ arrays of pixels with different pixel pitches and/or pixel widths and with different slant angles of pixels relative to a longitudinal dimension of the arrays.
