An image discrimination apparatus includes an inter-frame distance calculating unit 2 for calculating an inter-frame distance which is a distance between features from the feature of a current frame extracted by a feature extracting unit 1 and the feature of an immediately-preceding frame stored in a feature buffer 3, and a cut-point-determination data calculating unit 4 for calculating statistics values of inter-frame distances and calculating a threshold for determination of cut points from the statistics values. The image discrimination apparatus compares the inter-frame distance of the current frame with the threshold for determination of cut points to determine a cut point from the comparison result.
