Abstract
There is disclosed a zooming control device for a camera, enabling photographing with a constant magnification of an object, and still avoiding overflowing of an object from the photographed frame in zooming of the lens. The frame is divided into plural areas, and there is discriminated whether an object is present only in the central area, or also in the peripheral area or areas. In the former case the lens is zoomed to achieve a preset image magnification, but, in the latter case, the zooming is limited in order to avoid overflowing of an object from the frame.
