    摘要: An apparatus for detecting a caption from a moving picture, including: a caption domain detector selecting a candidate frame based on input genre information from an input moving picture and determining expectation caption domains from the selected candidate frame set; a target caption detector selecting target caption candidate domains based on repetition of a position or color pattern of the expectation caption domains and determining target caption domains based on a rate of change in a character or number domain from the selected target caption candidate domains; and a key caption detector detecting a key character or number information domain by analyzing the target caption domains.
