Video summarization device

Abstract

When a judgment result of a cut point judgment unit (16) at a cut point detection unit (1) indicates a cut point, a shot length calculation unit (2) for calculating the shot length of the shot starting at a cut point preceding the aforementioned cut shot by one. By using the shot length calculated by the shot length calculation unit (2) as a judgment material, it is judged whether the shot starting at the cut point preceding by one is an important shot.

Description

video summarization device technical field The present invention relates to a video summarization device capable of extracting video of an important section from a video signal, and reproducing or editing the video of the important section. Background technique Currently, an image summarization device is proposed that detects cut points of images, divides image signals into shot units, and identifies important shots from multiple shots. As disclosed in the following Non-Patent Document 1, for example, very complicated processing such as many image processing methods or audio processing methods is often used for important shot identification processing, and it is difficult to perform real-time identification or to install on portable devices. In addition, when editing or replaying actual sorted shots, a list of small images called thumbnails is often used. In this thumbnail, a representative image of each shot is used, and the head image of each shot is often used as a ...

Problems solved by technology

Since the existing video summarization device is structured as above, there is a problem that, for example, if it does not perform very complicated processing like many video processing methods or audio processing methods, important shots cannot be distinguished, and it is difficult to perform real-time discrimination or to portable Issues such as installation of equipment

In addition, since the opening image of a shot is not necessarily a representative image representing the shot, there is a problem that the user may not be able to determine where the shot he wants to view is located even if he looks at the list of thumbnails.
