Fast video browsing system
First Claim
1. A fast video browsing system for motion pictures in which by displaying the input pictures after the skipped input pictures on a display, the playback is performed faster than the normal playback to enable the contents of the pictures to be easily kept track of, comprising:
- an input means for inputting motion picture data stored in a storage device at a speed higher than the normal playback;
a motion amount detecting means for detecting the motion amount of an input picture inputted to said input means;
a number of skipped pictures determining means for determining the number of skipped pictures from the motion amount of said input picture detected by said motion amount detecting means; and
a display means for continuously displaying with a frame timing only the pictures after those skipped by the number of skipped pictures determined by said number of skipped pictures determining means, thereby to enable the playback and browsing to be performed faster than the normal playback.

Abstract
To provide a fast video browsing system in which a fast playback suitable for keeping track of the contents can be performed by adaptively determining the number of skipped pictures according to the motion vector of picture, and displaying the picture after the skipped pictures. In step S1, pictures to be fast viewed are sequentially inputted, and in step S2, n pictures are skipped. In step S3, the picture after the n skipped pictures is displayed. In step S4, using the picture before or after the displayed picture with respect to time, a motion vector at one frame interval is detected, and in step S5, the number n of skipped pictures is determined from the motion vector. As a result, the number of skipped pictures can be adaptively determined by the motion vector of a picture.

12. A fast video browsing system for motion pictures in which by displaying the input pictures after the skipped input pictures on a display, the playback is performed faster than the normal playback to enable the contents of the pictures to easily be kept track of, comprising:
-
an input means for inputting the motion picture compressively coding information stored in a storage device at a speed higher than the normal playback; a motion vector information extracting means for extracting motion vector information from the motion picture compressively coding information inputted to said input means; a motion amount determining means for determining the motion amount of a motion picture in a scene by using the motion vector extracted by said motion vector information extracting means; a number of skipped pictures determining means for determining the number of skipped pictures based on the motion amount of said motion picture; and a display means for continuously displaying with a frame timing only the pictures after those skipped by the number of skipped pictures determined by said number of skipped pictures determining means, thereby to enable the playback and browsing to be performed faster than the normal playback. - View Dependent Claims (13, 14, 15, 16)
