Abstract:
A method of detecting a change between video shots from a video including a plurality of succeeding frame images, said method comprising the steps of:inputting said video into a processing device;obtaining a feature quantity of each frame of the inputted video;determining a first correlation coefficient which is a difference between a feature quantity of a current frame image and a feature quantity of a first preceding frame image immediately preceding said current frame image;determining a second correlation coefficient which is a difference between the feature quantity of said current frame image and a feature quantity of a second preceding frame at least two frame image preceding said current frame image; andindicating a change between video shots a time when the first correlation coefficient and the second correlation coefficient are out of predetermined allowable ranges;wherein the number of frame images preceding said current frame image for said second preceding frame image is successively increased so as to distinguish a disturbance lasting an arbitrary number of frame images from a change between video shots.
