Patent ID: 8532189

Claim:
Method for detecting scene change in a sequence of video pictures, executed by a processor, comprising: detecting static areas in the current picture, wherein the static areas depend on the picture content; calculating a histogram for non-static areas of the current picture, wherein static areas of the picture are skipped; calculating the difference between the histogram of a current picture and the histogram of at least one preceding picture stored in a memory, declaring scene change if the difference is greater than a threshold, wherein the threshold is adaptive and predetermined, for a picture, in accordance with a percentage of static pixels constituting the static areas of the picture; wherein the threshold is adaptive according to S′=S*P NS /LC, wherein S is the threshold for the whole picture, P NS is the number of non-static pixels of the picture, and LC is the number of pixels in the whole picture, and wherein the cut detection is only valid above a defined minimum number of non-static pixels.
