To provide an apparatus which enables analyzing of the details in pitching made by a pitcher by reading the track of the pitching with a three- dimensionally analyzable device to display the data to the pitcher in the training of pitching for pitchers in base ball.

In linkage with a stroboscopic light emitter (2) controlled by a projection stroboscopic emission controller (9), a ball (9) is photographed with a central camera (3), a left eye camera (4) and a right eye camera (5), and an image processor (6) performs a stereoscopic image processing of the track of the ball (9). The results in the pitching are displayed on a display device (1) while being stored into a personal computer (8) for processing data as data base thereby enabling the analyzing of the details in the pitching.
