Abstract
A system and method for motion compensation of color sequential displays, receiving a motion image data input, extracting an estimate of a motion of an image portion represented in said image data input with a motion estimator, and calculating, for a time instance of display of each image subframe of an image frame, a compensated representation for reducing display artifacts with a processor, wherein each subframe represents a different aspect of the image frame. The subframes are preferably different color planes of the image frame. The processor preferably performs a bilinear interpolation where the compensated image boundary does not fall on a display pixel boundary. The motion compensation algorithm is preferably robust in the face of erroneous motion vectors. The system and method is advantageously used in single panel liquid crystal display projection systems, although the techniques are applicable to various image display technologies.
