Abstract:
1. An image pickup apparatus having a zoom function, comprising: an X-Y address type image pickup device which photoelectrically converts an image of a subject image formed by an optical element with two-dimensionally arranged pixels, and outputs a picture signal reading from the pixels a charge into which the image is photoelectrically converted, wherein the image pickup device designates a position in the two-dimensionally arranged pixels by a combination of an X address and a Y address; optical zoom means which performs optical zooming by changing a pickup angle of view which becomes the field of the subject image formed on the image pickup device; electronic zoom means which performs electronic zooming by changing a clipping angle of view which is a clipping range of the pickup angle of view, wherein an address range formed of a combination of a range designated by an X address and a range designated by a Y address is changed when the pixels of the image pickup device are read; and control means which controls a combination of the electronic zooming by the electronic zoom means and the optical zooming by the optical zoom means to obtain a zoom range of an output angle of view of a finally output picture signal.
