Abstract
A scene change point detecting method which detects a scene change point by successively processing time series frame images I1, I2, I3, - - - sampled in this order from a processed video. The method includes at least one of the following four scene-change-point detecting methods: a first scene-change-point detecting method for detecting a video cut; a second scene-change-point detecting method for detecting a scene change similar to dissolve by processing a feature quantity to be calculated based on an edge intensity of each frame image; a third scene-change-point detecting method for detecting a scene change similar to wipe based on an intensity-changed pixel region representing a set of pixels whose brightness changes more than a predetermined threshold between a specific frame image In and an immediately preceding frame image In-1; and a fourth scene-change-point detecting method for detecting a scene change similar to page-translate or a scene change resulting from camera movement based on an intensity-changed pixel area representing a ratio of the number of pixels involved in the intensity-changed pixel region to the total number of pixels constituting a corresponding frame image.
