PROBLEM TO BE SOLVED: To create user-friendly thumbnails by properly dividing temporally continuing contents into chapters and to detect highlight scenes at proper timings. SOLUTION: A feature extraction section 3 extracts a plurality of features (color signal intensity, sound volume, character information of captions, and the like) from AV data included in the contents. A synthesis section 5 generates first and second synthesized features G1, G2 by calculating the plurality of features. A chapter dividing section 6 divides the contents into chapters based on the first synthesized feature G1. A thumbnail producing section 7 detects highlight scenes based on the second synthesized feature G2. COPYRIGHT: (C)2009,JPO&INPIT
