Abstract: PROBLEM TO BE SOLVED: To generate a summary of video images along user's preference. SOLUTION: This device generates a summary from video images and is provided with a means that extracts numerical data from objective video images, a means that decides an important part of each scene on the basis of the extracted numerical data and a means that generates a summary from parts of the importance, that have a value which is a prescribed threshold or higher.

Abstract: PROBLEM TO BE SOLVED: To provide a technique for effectively discriminating occlusion of an object, such as humans, having flexibility. SOLUTION: After initialization (step 1), an image is inputted (step 2), and an image area is extracted (step 4) by separating a background and a foreground from each other. In extraction of the area, the shape of a two-dimensional histogram of a color space can be used. In consideration of all possible connecting methods of the extracted area, a graph is formed (step 5), while using an area between frames as a node. The node can be provided with a variable value of a confidence factor, and an edge connecting the nodes together can be provided with image characteristics of the color space and an actual space as the weight. In a graphing process (step 6), path finding is carried out on a path of a graph, and a connecting method having a low possibility as the path is eliminated from a path confidence factor. A branching node is detected as occlusion, to be marked up. When connectivity of the occlusion part is a single possibility, this connection is selected.
