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. Tracking is continued even if the position of the focus lens falls into the predetermined focus allowance, so as to make it possible to take a well-focused photograph at any time.
