Form evaluation system and method

Abstract

It is sought to provide a form evaluation system, which permits clear visual comparison of an ideal form and the own form on an image and accurately understanding points to be improved. A database is formed with check points of the form in golf, for instance, as reference data of form evaluation. A predetermined division number of still images are produced from motion picture image data of subscriber, these still images are displayed on a personal computer display screen, the form of the subscriber's still images is evaluated with the database as reference, and on the basis of the evaluation a form evaluation sheet is produced, which contains a predetermined division number of serially changing still images and form guide comments each provided for each of these still images.
