Abstract

Une image en mouvement d’un joueur lorsqu’il frappe une balle avec un club de golf est capturée par une caméra vidéo numérique (16) pour le côté avant, et l’image en mouvement est stockée continuellement dans une mémoire tampon (26) pour le côté avant. Le mouvement de la balle frappée est détecté par un capteur Doppler (14) et la vitesse de la balle est mesurée par une unité de mesure de la vitesse de la balle (24b). Un temps de traitement pris pour mesurer la vitesse de la balle est mesuré par une unité de mesure du temps de traitement (24a) et un temps de retard après l’apparition d’un déclencheur est calculé sur la base du temps de traitement, et ainsi l’image de l’élan est extraite par rapport à l’image au moment de l’impact.
