The detecting of the common section comprises comparing moving picture segments by generating commonality evaluation value of a first moving picture segment and a second moving picture segment by comparing feature vectors of p frames of the first moving picture segment of the first moving picture with feature vectors, corresponding arrangement to an arrangement of the p frames of the first moving picture segment, of p frames of the second moving picture segment of the second moving picture, p being a natural number of greater than or equal to 1. The first moving picture segment has a start time of tl after the first moving picture starts and the second moving picture segment has a start time of t2 after the second moving picture starts. The comparing of moving picture segments is repeated for tl and t2, tl being a start time of the first moving picture segment that is equal to or greater than 0 and is smaller than a length of the first moving picture, t2 being a start time of the second moving picture segment that is equal to or greater than 0 and is smaller than a length of the second moving picture. The detecting of common section comprises detecting a common section start-end point by detecting a start time and an end time of a common section in the first moving picture and the second moving picture, respectively, by comparing the feature vector of the first moving picture with the feature vector of the second moving picture by applying a greater number of frames per second than the number of frames per second of the p frames in the first moving picture segment and the second moving picture segment, in case the commonality evaluation value indicates that there is commonality in the first moving picture segment and the second moving picture segment.
