Digital Video Recorder is widely used to visualize the dynamic image of moving body. In the field of motion science, DVR is often applied to study two and three-dimensional moving images of the human body under walking, running and jumping by means of several tracer markers on the body surface. In this study, the high-speed infrared radiometer IR simultaneously visualized the visual and thermal image of the moving human body using thermal marker and thermal footmarks. Characteristics of single- and multi-flash imaging methods were evaluated using the dynamic motion recorder.
