PROBLEM TO BE SOLVED: To provide a cut detection device and its program capable of reducing erroneous detection of a hard movement scene in cut detection of image data. SOLUTION: A vector calculation processing part 19a partitions a frame into the prescribed number of blocks, and calculates a moving vector between frames in each block. A classified block number accumulation processing part 19b classifies moving vectors in each block calculated between the frames into the prescribed number of directions, accumulates the number of blocks corresponding to the moving vectors classified into each direction, and calculates the number of blocks classified by the direction. An absolute value differential quantity calculation processing part 19c determines the difference classified by the direction between the number of blocks classified by the direction between the frames and the number of blocks classified by the direction between front or rear frames relative to the frame interval, and calculates the absolute value differential quantity based on the absolute value of the difference. This cut detection device detects a cut part from the image data based on the calculated absolute value differential quantity. COPYRIGHT: (C)2003,JPO
