Abstract
A method of processing image data comprises receiving input signals for specifying red, green and blue colors of the pixels of a display, performing a per-pixel low pass filtering of the input signals, the low pass filtering function being dependent on the chrominance variation between adjacent pixels, and providing the filtered output signals for use in driving the pixels of a display. This method essentially measures the chrominance variation of the incoming signal, in the form of the color change frequency, and depending on this variation, adaptively low-pass filters the incoming signal. This can be in such a way that the chrominance resolution of the outgoing signal is below the maximum chrominance resolution of the intended display, without errors in the average color of a small group of pixels.
