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 a focus prediction that is executed from repeated distance measurements. The focus lens is additionally driven during a release-time-lag by an amount corresponding to the amount of movement of an image of the photographing object formed by the focus lens during a time from a reference time after completion of the lens drive to a time of occurrence of a release interruption, when a release interruption occurs.
