Abstract:
1. A method for generating successive frames of a video display in response to first pixel data describing an image, wherein each frame comprises an active area of first pixels forming the image, and second pixels outside of the active area, wherein the first pixel data indicates magnitudes of at least one of luminance and chrominance of each first pixel of each successive frame, the method comprising the steps of, for each particular frame of the successive frames: processing the first pixel data to calculating a first estimated magnitude of at least one of luminance and chrominance of a selected first group of the first pixels; generating second pixel data indicating magnitudes of said at least one of luminance and chrominance of second pixels of the particular frame, wherein the indicated magnitude of said at least one of luminance and chrominance of each second pixel of the particular frame is a function of the first estimated magnitude; setting said at least one of luminance and chrominance of the first pixels of the particular frame to magnitudes indicated by the first pixel data; and setting said at least one of luminance and chrominance of the second pixels of the particular frame to magnitudes indicated by the second pixel data.
