Abstract:
1. A video processing apparatus for specifying frames of content to be start frames of a plurality of viewing segments of the content, when segmenting the content into the plurality of viewing segments, the video processing apparatus comprising: a specifying information memory, which is a physical memory storing a plurality of pieces of specifying information, each piece of specifying information of the plurality of pieces of specifying information (i) corresponding to a different type of content, and (ii) including: a content obtaining unit operable to obtain a content; an information obtaining unit operable to obtain type information identifying the type of the obtained content; an extracting unit operable to extract, from the specifying information memory, a piece of specifying information, of the plurality of pieces of specifying information, that corresponds to the type of the content identified by the obtained type information; and a specifying unit operable, in accordance with the extracted piece of specifying information, to (i) specify the presentation frames of the content by detecting, from all frames of the content, frames of the content satisfying the first condition and by subsequently excluding, from the detected frames satisfying the first condition, frames satisfying the exclusion condition, and (ii) specify start frames of the content by detecting, from all frames of the content, frames of the content satisfying the second condition and by subsequently selecting, from the detected frames satisfying the second condition, frames satisfying the relationship identified by the selection condition with respect to the specified presentation frames, wherein specifying unit includes: wherein each of the first condition, the exclusion condition, and the second condition is an identifier to be used by one detecting subunit of the plurality of detecting subunits, and wherein, when operating in accordance with the extracted piece of specifying information corresponding to the type of the content identified by the obtained type information, the specifying unit (i) detects, from all frames of the content, a plurality of large-caption start frames, each large-caption start frame, of the plurality of large-caption start frames, being a first frame of a series of frames of the content during which a caption of a size larger than a threshold continuously appears in a predetermined region, and (ii) specifies, as a presentation frame of the content, each large-caption start frame, of the plurality of large-caption start frames, remaining after removing, from the plurality of large-caption start frames, small-caption frames having a caption of a size smaller than a threshold appearing in a region other than the predetermined region.
