Abstract
A hardware implemented method for reducing noise in an image is provided. In this method, a difference between color values of corresponding pixels within the image is calculated, and the calculated difference is compared with a threshold value. The threshold value is defined as a rate of color value change between the corresponding pixels. If the calculated difference is greater than the threshold value, the color value of at least one of the corresponding pixels is replaced with an average color value. A graphics controller and image capture device interface for reducing noise in an image also are described.
