ABSTRACT:
An image pickup apparatus includes an image pickup element for picking up an image of a subject and outputting a picked-up image signal, an electronic image magnification enlarging circuit for enlarging an image magnification of the subject by intermittently reading out the picked-up image signal outputted from the image pickup element and varying an image read-out area of an image plane, an exposure control circuit for executing exposure control on the basis of a result obtained by comparing a level of the picked-up image signal with a predetermined reference level, and a correcting circuit for correcting, according to the image magnification of the electronic image magnification enlarging circuit, a no-signal-containing portion produced by an operation of the electronic image magnification enlarging circuit and contained in the picked-up image signal to be supplied to the exposure control circuit.
