Abstract:
1. A video-attribute-information output apparatus comprising: a scene dividing unit that detects a change in scenes where there is little similarity between frames of video content, and divides the video content into a plurality of scenes; an attribute-information-area extracting unit that extracts an attribute information area in which attribute information is displayed and which has no change between specific frames of adjacent scenes that are obtained by dividing by the scene dividing unit; a character-area extracting unit that extracts character areas in which video attribute information in individual characters that is metadata of the video content is present, from the attribute information area extracted by the attribute-information-area extracting unit; a character-area-meaning assigning unit that assigns meanings to the character areas extracted by the character-area extracting unit, by referring to rule information that specifies the meanings for the character areas; a video-attribute-information output unit that reads the video attribute information from the character areas to which the meanings are assigned, and outputs the video attribute information; a typical scene extracting unit that extracts typical scenes that are images shot in a same composition and repeatedly appear in the video content, from the adjacent scenes obtained by dividing by the scene dividing unit; and a region judging unit that judges whether each of the extracted typical scenes has the extracted attribute information area, wherein the character-area extracting unit extracts character areas in which the individual characters are present in the extracted attribute information area and judged as being in a typical scene by the region judging unit.
