Abstract: There is provided a method for detecting change points between cuts from motion picture images including a plurality of consecutive images. First of all, in this method, motion picture images which are the subject of detection of change point between cuts are inputted in a time series by taking a frame as the unit, and a predetermined feature quantity including a color histogram possessed by image data of said motion picture images is produced while taking a frame as the unit. A correlation coefficient with respect to feature quantity between the above described feature quantity and a feature quantity produced in an immediately preceding frame is then produced. Further, a change rate between the correlation coefficient of the current frame and a correlation coefficient produced for a frame preceding the current frame is produced. A time point whereat the change rate exceeds a predetermined allowable value is detected as a change point between cuts of the motion picture images.
