Abstract
An image processing circuit compares a pixel value to a threshold value and modifies the pixel value if the pixel value has a predetermined relationship to the threshold value. Alternatively, the image processing circuit generates a random number and combines the random number with a pixel value. Such image processing circuits can be used to remove artifacts such as contour artifacts from a decoded electronic image or a sequence of decoded video frames.
