METHOD AND APPARATUS FOR DETECTING FADE OF IMAGE IN A VIDEO SIGNAL

Method and apparatus for detecting fade of a video signal which can detect a fade state of an image from a video signal at a high speed. It is determined that an image based on an original video signal is in a fade state when the absolute value of the difference between the total luminance value of original video signal of one frame and the total luminance value of the neighboring video signal of one frame which are neighboring just before or after the original video signal is relatively large and the number of pixel data in which the absolute value of the difference between each pixel data in the original video signal of one frame and each pixel data in the neighboring video signal is relatively small with respect to pixels existing at the spatially same position is large.
