Patent ID: 11929019
Assignee: REALTEK SEMICONDUCTOR CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 15:
16. A circuit system, comprising:
an image processing circuit, performing a method for processing static pattern in an image,
including:
receiving a video;
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 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; and
receiving, by a display control circuit, the brightness value processed by the image processing circuit so as to output the brightness value to a driving circuit of a display, and displaying the image by the display.
