Claim 7:
8. A display control chip, comprising a computing circuit configured to:
receive a video signal configured to transmit an image of a frame;
with respect to a plurality of sub-areas different to each other in an area of the image, calculate a pixel number distribution of each sub-area along a plurality of characteristic values;
determine, according to the pixel number distribution, whether the sub-area comprises a corresponding first target pattern of a plurality of first target patterns;
if the plurality of sub-areas comprise the plurality of first target patterns, respectively, perform a first preset image processing to the image to generate a processed image;
if the plurality of sub-areas are free from comprising the plurality of first target patterns, respectively, omit the first preset image processing to the image; and
generate a display signal according to the processed image or the image.
