Automatic focusing apparatus of a camera |
摘要 |
An automatic focusing apparatus of a camera according to the present invention includes: a focus detector which detects repeatedly focus conditions of a photographic lens and outputs successively focus signals corresponding to the focus conditions; a drive unit for driving the photographic lens for focus adjustment; a predictor for predicting an in-focus point from the plurality of focus signals from the focus detector; a control unit for controlling the drive unit to drive the photographic lens toward the in-focus point predicted by the predictor; an auxiliary light projector for projecting auxiliary light onto an object to enable detecting operation of the focus detector; and a forbidding device for forbidding the control of drive by the control unit while the auxiliary light is projected by the auxiliary light projector.
