PROBLEM TO BE SOLVED: To reduce constraints of an analysis object when the state of the analysis object is to be analyzed as viewed in a photographed image.SOLUTION: An imaging device 1 comprises a resolution filtering unit 41 and an analyzer 40. The resolution filtering unit 41 extracts the state of irradiation of a golf ball Ba, which is the analysis object, with light in a planar way in the traveling direction of the golf ball Ba. The analyzer 40 analyzes, on the basis of the state of irradiation extracted by the resolution filtering unit 41, the moving state in a direction substantially orthogonal to the traveling direction of the golf ball Ba. |
