Abstract
An image pickup apparatus photoelectrically converts image light from an object. The image light incident on the photosensing plane of the image pickup apparatus is optically controlled by a zoom lens and a focus lens. A controller drives the zoom lens to its telephoto position and drives the focus lens to its closest position so that bright image light is prevented from being focused on the photosensing plane.
