Claim 0:
1. A method for processing a static pattern in an image that is adapted to a circuit system, wherein the method comprises:
calculating a static pattern index for each pixel of every frame of a video or every divided area of the video, wherein the static pattern index indicates a score of every pixel or every area of every frame that is determined as a static pattern;
determining the pixel or the area having the static pattern of every frame by an index threshold, and determining the pixel or the area having the static pattern of the video by a time threshold;
calculating a weight for adjusting a brightness value of the pixel or the area having the static pattern by referring to a non-static-pattern brightness curve and a static pattern brightness curve with respect to a current frame according to the static pattern index of the pixel or the area that is determined as the static pattern; and
adjusting the brightness value of the pixel or the area that is determined as the static pattern with the weight.
