Embodiment Construction

[0058] Embodiments of the present invention will be described in detail with reference to the drawings.

[0059] figure 1 A schematic diagram illustrating the functional structure of the video content processing device 10 according to the embodiment of the present invention. The video content processing device 10 shown in the figure includes an image storage unit 11 , a scene change detection unit 12 , a theme detection unit 13 , an index storage unit 14 , and a playback unit 15 .

[0060] The image storage unit 11 demodulates and stores broadcast waves, and stores video contents downloaded from information sources via the Internet. For example, the image storage unit 11 may be constituted by a hard disk recorder.

[0061] Scene change unit 12 retrieves video content subjected to subject detection from image storage unit 11, tracks scenes (scenes or sets) included in consecutive images, and detects scene change points where scenes change significantly due to switching of ima...

Abstract

Changes in themes in the image content are detected by utilizing subtitles contained in the image, and the content is segmented on a per-theme basis. First, scene change points that significantly change the scene by image switching are detected in image content. Next, an average image of frames one second before and after the scene change point is formed, and, with high precision, whether or not subtitles appear at the scene change point is detected using the average image. Segments in which equivalent static subtitles appear are detected to create index information about a time period of each segment in which equivalent static subtitles are displayed.

Description

technical field [0001] The present invention relates to a content processing device configured to perform processing such as indexing on video content obtained by, for example, recording a television program, and to a method and a computer program for processing the content. Specifically, the present invention relates to a content processing device configured to determine a scene change of a recorded television program on the basis of the title (i.e., theme) of the television program, and to perform segmentation or classification of the scene, and to processing content Methods and Computer Programs. [0002] More particularly, the present invention relates to a content processing device configured to detect theme changes on the basis of telops included in video content, perform segmentation of video content on the basis of the detected theme, and perform indexing , and relates to methods and computer programs for processing content. In particular, the present invention relat...
