Region of interest identification device, region of interest identification method, region of interest identification program, and region of interest identification integrated circuit

摘要

An interesting section identifying device for identifying an interesting section of a video file based on an audio signal included in the video file, the interesting section being a section in which a user is estimated to express interest, includes an interesting section candidate extracting unit that extracts an interesting section candidate from the video file, the interesting section candidate being a candidate for the interesting section, a detailed structure determining unit that determines whether the interesting section candidate includes a specific detailed structure, and an interesting section identifying unit that identifies the interesting section by analyzing a specific section when the detailed structure determining unit determines that the interesting section candidate includes the detailed structure, the specific section including the detailed structure and being shorter than the interesting section candidate.
