Abstract
The present invention relates to a method for detection of film mode or camera mode of a video sequence. This detection is carried out using histograms of video levels of frames of the video sequence. Difference histograms are calculated then compared with each other so as to generate difference parameters for each video frame of the sequence. The pattern formed by these difference parameters is then compared with predetermined patterns to deduce the mode, film or camera, of the sequence. The advantage of this method is that it requires just small memory resources for its implementation and can therefore be implanted in an FPGA circuit.
