摘要：
A scene switching point detector includes: a feature-information generating unit that generates feature information indicating a feature of each of target frames; a backward-similarity calculating unit that sets each of the target frames as a similarity calculation frame in order and calculates backward similarity on the basis of the feature information of the similarity calculation frame and the feature information of the target frames temporally located before the similarity calculation frame; a forward-similarity calculating unit that sets each of the target frames as a similarity calculation frame in order and calculates forward similarity on the basis of the feature information of the similarity calculation frame and the feature information of the target frames temporally located after the similarity calculation frame; and a scene switching point detector that detects the target frame forming a scene switching point on the basis of the backward similarity and the forward similarity.
