| Research Abstract |
High-speed focusing vision, that is composed of millisecond high-speed vision and millisecond high-speed imaging optics using high-speed liquid lens, was proposed. The proposed vision system could both capture images and also control its focal length in millisecond. Three new algorithms were developed due to the advantage of the matched bandwidth ;(i) an algorithm synthesizing extended focus images with high frame rate,(ii) synthesizing a virtual image with arbitrary depth of field and focal position,(iii) estimating 3-dimensional movement of objects from the image sequence while the focal length was vibrated at high rate. Furthermore, a new optical unit called Saccade Mirro was also developed to achieve millisecond gaze control of the vision system. Due to the high-speed response, a high-speed target such as a bouncing ball was successfully tracked using the developed unit.
