摘要

A judgment-assistance processing device includes a frame-display control unit that causes frames of lines on a court for a ball sport to be displayed on a display unit; a movement-information extracting unit that detects a ball from the frames displayed on the display unit and extracts movement information that indicates the moving velocity and the moving direction of the ball; an upon-reversal information extracting unit that detects whether the moving direction of the ball is reversed in the first direction and extracts at least the magnitude of the component of the moving velocity of the ball upon reversal; a frame selecting unit that selects the one or more frames from the frames in accordance with the magnitude of the component of the moving velocity of the ball upon reversal; and a highlighted-display control unit that highlights the one or more frames that are selected from the frames.
