ABSTRACT:
An optical apparatus includes area sensors which are made to differ in picture element pitch between the central portions and the marginal portions thereof (the marginal portions are made to have a coarse picture element pitch since it is not very meaningful even if the picture element pitch is made fine because the performance of an optical system is limited, and the central portions are made to have a dense picture element pitch) and the changeover of the respective picture elements is electronically effected by reading-out means so that two kinds of object field information (detailed information and coarse information) may be obtained from the area sensors.
