Abstract
A television (TV) image adjusting method includes performing a variance calculation on luminance values of a plurality of pixels adjacent to target pixels of an image frame to generate a weight index; performing a decay function calculation according to the weight index to generate a weight distribution corresponding to the plurality of pixels adjacent to the target pixels. A function value of the decay function is inversely proportional to both the weight index and a target pixel distance between the target pixels and the plurality of pixels adjacent to the target pixels. The target pixel distance is a sum of vertical distances and horizontal distances between the target pixels and the plurality of pixels adjacent of the target pixels. The method further performs a weight calculation on the luminance values of the plurality of pixels adjacent to target pixels according to the weight distribution to generate an output luminance value.
