    • 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.
    • 提供了一种用于判断视频模式的方法和装置。 该方法比较视频数据中两个连续帧的相应像素的值,以获得两帧之间的差值,然后收集任何两个连续帧之间的所有差值以形成差值序列。 差值序列由高通滤波器进一步放大,然后与阈值进行比较。 提供比较结果用于连续地判断视频数据的电影模式。 由于放大的信号值适合于强调每帧的差异,因此所提供的方法能够更准确地识别原始视频数据的电影模式,这进一步消除了现有技术中的难点,即难以确定阈值 值或判断其电影模式。
