More Information
Summary:A method for processing a static pattern in an image is provided. In the method, each of frames of a video is divided into multiple regions. Several algorithms are used to calculate a static pattern index of every region. The static pattern index is used as a reference for determining if the region covers part or all of a static pattern. An index threshold can be used to check the regions that are determined as the static pattern preliminarily. A time threshold is then used to confirm the regions with the static pattern in every frame. After that, the image data of the regions which are determined as the static pattern can be adjusted for preventing the display panel from negative effects of static pattern. The image data to be adjusted is such as brightness of the region that is determined as part or all of the static pattern.
