Outline of Final Research Achievements

This study proposed a simultaneous intermittent tracking method for high-brightness motion-blur-free video shooting. We built a prototype of motion-blur-free camera consisting of a piezo-actuator and a high-speed vision system, and demonstrated the effectiveness of our simultaneous intermittent tracking method that enables wide dynamic-range video shooting of fast-moving objects without decreasing the camera exposure time. In fact, we verified the basic performance of the prototype by showing the quantitative relationships of camera shutter time and frame interval, measurable velocity range to be tracked, and sharpness of captured images when the high-speed vision hardware and high-speed piezo actuator were operated in real time for frame-by-frame intermittent tracking at hundreds of Hertz.
