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 image of the inputted video;determining a nth first correlation coefficient which is a difference between a feature quantity of a nth frame image of frame number n and a feature quantity of a first preceding frame image immediately preceding said nth frame image;determining a nth second correlation coefficient which is a difference between the feature quantity of said nth frame image and a feature quantity of a second preceding frame image at least two frame images preceding said nth frame image, where n is an integer greater than 2; anddetecting a change between a (n-1)th frame image and a (n-2)th frame image at a time when a (n-1)th first correlation coefficient and a nth second correlation coefficient are out of predetermined allowable ranges and the nth first correlation coefficient is within said allowable ranges.
