<p>PROBLEM TO BE SOLVED: To identify a specific subject accurately without requiring an enormous amount of computation.SOLUTION: In an image determination device 1, an image acquisition part 43 acquires an image including an image of a golf ball 73. A first detection part 44 detects an effective edge present in a prescribed direction in an area between double circles so as to determine presence of the image of the golf ball 73 that can be in the area between the double circles in the image acquired by the image acquisition part 43. A first presence determination part 46 and a second presence determination part 51 determine whether or not the image of the golf ball 73 is present in the area between the double circles on the basis of a detection result of the effective edge detected by the first detection part 44.</p> |
