ABSTRACT:
A method and an apparatus for judging video modes are provided. The method compares the values of the corresponding pixels of two consecutive frames in a video data to obtain a difference value between the two frames and then all of the difference values between any two consecutive frames are collected to form a difference value sequence. The difference value sequence is further amplified by a high pass filter and then compared with a threshold value. The comparison result is provided for successively judging the movie mode of the video data. Since the amplified signal values are suitable for emphasizing the difference of each frame, the provided method is capable of more correctly identifying the movie mode of the original video data, which further eliminates the drawback in the prior art that it is hard to determine the threshold value or to judge the movie mode thereof.
