Abstract
A method for enhancing the high frequency information of an object being viewed by a video camera, to detect edges and object detail more accurately by projecting a preselected optical pattern onto the surface of the object. As the spatial plane of the camera travels through the object space, the projected pattern follows, always remaining in focus with the moving plane. The sharp detail of the pattern adds to the high frequency information read by the camera when the viewed object comes into focus and peaks when the object is in focus.
