摘要

PROBLEM TO BE SOLVED: To make an inquiry about the meaning of the contents of a video by using a highly abstract term or concept and to perform retrieval at a high speed. SOLUTION: In a video retrieval method, a structural unit which is suitable as a unit to be retrieved at the time of retrieving a video is set as a retrieval granularity with respect to a term which can be expressed by the combination of a plurality of events, and the state transition pattern corresponding to the term is defined as the input column of a plurality of event indexes which are continuously generated in a retrieval granularity on the basis of generation pattern of the event expressing the term. When a desired video scene is retrieved from the video, the term expressing the desired video scene is inputted and whether the state transition pattern corresponding to the inputted term coincides with the generation pattern of an event index in the structural unit is discriminated at every structural unit which is coincident with the retrieval granularity by using the retrieval granularity corresponding to the inputted word as a retrieval object unit. The coincident structural unit is outputted as a retrieved result.
