Motion-blur-free High-speed Video Shooting with Frame-timing Control

We developed a motion-blur-free video camera for shooting non-blurred videos of unstable fast-moving objects by implementing an improved actuator-driven frame-by-frame intermittent tracking method on a high-speed vision platform and an external field-programmable gate array board. With our tracking method, the camera frame-timing is controlled so that the speed of the camera viewpoint coincides with the apparent speed of the target object during the camera exposure time. Our motion-blur-free video camera can shoot non-blurred 1024×1024 images of fast-moving objects at 750 fps until 7.5 m/s unidirectionally. Compared with the degradation in video recorded without tracking, our method reduces image degradation from motion blur 1/10 times or less without shortening the exposure time. Its performance was verified by the experimental results of several fast-moving objects using a high-speed conveyor belt system.
