Abstract
In this paper, we propose a new zoom and focus tracking system. First, a new zoom and focus mechanism for a high speed-vision is proposed. The mechanism consists of a varifocal lens and two DC blush motors. It is lightweight, and it has good performance to be controlled at high speed. Next we design a control system for a high-speed zoom and focus mechanism for a high-speed vision. In the control system, zoom is controlled by the area of a target, and focus is controlled based on SML(Sum of modified Laplacian).
