Patent ID: 7857708

Claim:
A golf swing-diagnosing system to permit a adjustment of a golf swing comprising a computer for capturing a golf swing colored moving image and for capturing a number of still frames from the colored moving image in which a golfer swinging by gripping a golf club is photographed, wherein said computer comprises: an extraction means for selectively extracting one or more individual still images each individual still image showing a swing posture as a check-point image, wherein the one or more individual still check-point images are selected from the group consisting of an address image, a take-back shaft 8 o'clock image, a take-back shaft 9 o'clock image, a take-back unskillful arm horizontal image, a top image, a downswing unskillful arm horizontal image, a downswing shaft 9 o'clock image, an impact image, a follow-through shaft 3 o'clock image, and a finish image from a large number of still images constituting said color moving image; means for extracting a plurality of different colored marks attached to the golfer or the golfer's golf club or a plurality of attention-focused points from each individual still check-point image sufficient to diagnose the golfer's swing; means for obtaining a coordinate of a position of each of a plurality of different colored marks attached to a golfer or a golf club, and/or of a plurality of attention-focused points comprising a golfer's silhouette, contour of the golfer's silhouette, the curvature of the contour of a golfer's silhouette, a straight line associated with the contour of a golfer's silhouette, edge extraction characteristics of a golfer's silhouette, a color of a golfer's garment, and a golfer's skin color, which operate, in each of said individual still check-point images, while said golfer is swinging, wherein sufficient different colored marks and/or attention-focused points are used to diagnose the golfer's swing; a means for diagnosing a swing form of said golfer by setting a plurality of diagnosis items each including a swing posture and a shaft angle for each trajectory pattern and by comparing numerical data generated from data of said coordinate of said position of each of said attention-focused points in each of said check-point images with a judgement value which is an ideal value inputted to said computer in advance; and a means for outputting an advice drill corresponding to a result of each of said diagnosis from a data base in which a plurality of advice drills prepared as a practicing method for improving a swing form is registered.
