Claim One:
1. A scene classification apparatus of video for classifying a sequence of shots into a dynamic scene with much motion or a static scene with little motion, where the dynamic scene and the static scene respectively include a plurality of continuous shots and are thus a larger unit than a shot, comprising: a shot segmentation device to segment the video into respective shots based on a cut points; a calculator for calculating shot density DS of the video per a time unit from the respective segmented shots; a calculator for calculating motion intensity per unit region on an image using a value of motion vectors of the respective segmented shots; and a dynamic/static scene classifier for classifying the sequence of shots into the dynamic scene with much motion, the static scene with little motion or an other scene except the dynamic scene and static scene based on the shot density and the motion intensity of the respective segmented shots, wherein each scene includes a plurality of cut points, wherein the dynamic/static scene classifier classifies a sequence of shots whose shot density is larger than a first reference density and whose motion intensity is stronger than a first reference intensity into the dynamic scene, and classifies a sequence of shots whose shot density is smaller than a second reference density and whose motion intensity is weaker than a second reference intensity into the static scene, wherein a sequence of shots whose shot density is not larger than the first reference density or whose motion intensity is not stronger than the first reference intensity, and a sequence of shots whose shot density is not smaller than the second reference density or whose motion intensity is not weaker than the second reference intensity are classified as neither the dynamic scene nor the static scene.
