Abstract:
A method of reducing visual artifacts in a blend zone of at least two projector images is provided. The method comprises determining a maximum intensity variance for each pixel group within a blend curve of the blend zone, the maximum intensity variance being based on a blend multiplier selected to achieve a net light intensity specific to the location of the pixel group within the blend curve. For each pixel group, a first adjusted blend multiplier is determined, wherein the blend multiplier is increased by at least a portion of the maximum intensity variance. For each pixel group, a second adjusted blend multiplier is also determined, wherein the blend multiplier is decreased by at least a portion of the maximum intensity variance. The light intensity of each pixel in each pixel group is adjusted using the first and second adjusted blend multipliers specific to each pixel group. The average pixel intensity of each pixel group after application of the first and second adjusted blend multipliers remains equal to the net light intensity of the pixel group within the blend curve.
