摘要： In an automatic zooming device, an amount of movement of a focusing lens and that of a zooming lens are respectively monitored. When the focusing lens moves, a driving circuit drives the zooming lens to move until the monitored amount of movement of the zooming lens is brought into a given correlation to that of the focusing lens, so that automatic zooming can be accomplished with a very simple structural arrangement.
