Patent ID: 8351697

Claim:
Method for detection of film mode or camera mode of a sequence comprising at least three consecutive video frames, wherein it comprises the following steps, carried out by a processing unit: determine a histogram of the video levels of each of the video frames, calculate, for each of the video frames of the sequence, a value representative of the histogram difference, called histogram difference value, between the histogram of said video frame and the histogram of the next video frame, compare the histogram difference value of each of the video frames of the sequence with at least one comparison value to generate, for each of said video frames, a parameter, of difference, whose value is representative of the character different or not to that of said video frame with respect to the next video frame, and compare the pattern formed by the values of difference parameters of video frames of the sequence with a plurality of predetermined patterns to generate mode information identifying the mode, film or camera, of said sequence of video frames.
