PROBLEM TO BE SOLVED: To create a digest for making it easy for a user to obtain the content of a whole video. SOLUTION: A unit 16 for determining the number of digest segments in a scene partitions and allocates a total number of cuts Ac to be extracted as digest segments to the scenes among scenes of which a digest is to be created. A feature value detection unit 17 selects multiple representative frames from the frames contained in cut extraction scenes as scenes having one or more digest segments to be extracted, and detects, as the feature value of each representative frame, the number of imaged faces in each representative frame, the position of the largest face in the representative frame, and the size of the largest face. An importance calculation unit 20 calculates the importance of each representative frame on the basis of the feature value thereof, and a digest segment selection unit 21 determines the digest segment to be selected from each cut extraction scene on the basis of the feature values and importance of the representative frames from each cut extraction scene.
