Photographing is carried out by means of the first cameraafter a predetermined time passes since the golf ballis hit, and the photographing is carried out by means of the second cameraafter a predetermined time further passes. A magnified image is formed by original image data thus obtained and a read value obtained by pointing the magnified image is subjected to distortion correction or oblique correction so that correction data are obtained. Based on the correction data, a flight speed, a spin rate or a launch angle of the golf ballis calculated.
