ABSTRACT:
An automatic focusing device, in which a focus lens is driven for tracking an object-in-motion to obtain an in-focus state, based upon focus prediction executed from repeated distance measurements. An in-focus indication is made when it is determined that the in-focus state will be obtained after an elapse of a predetermined time.
