Swimming is a successive motion of the propulsive movement and the recovery movement in the water. It is very helpful to grasp a total swimming form for the improvement of the swimming technology. But it is very hard to visualize a series of motion on account of different refractions of the water and the air especially in a swimming pool. An underwater camera and an over water camera were loaded onto a cart placed on a rail of poolside. Underwater and overwater images were blended into a continuous image in a real time by a video mixer. Swimming motion data could be also visualized by three-dimensional acceleration and angular velocity data logger. Both motion picture and corresponding data were put together into a series of motion picture in order to observe the swimming motion. Captured data were patterned by wavelet transform.
