A Deconvolution Method for LCD Motion Blur Reduction

Liquid crystal displays (LCD) have shown great promise in the consumer market for their use as both computer and television displays. Despite their many advantages, the inherent nature of LCD image formation results in a phenomenon known as motion blur. LCDs emit light and aim to hold it constant during the entire frame time. In this paper we develop a method for motion blur reduction using the Richardson-Lucy deconvolution algorithm in concert with motion vector information from the scene. In addition, we derive a general lower bound on the performance of the deconvolution algorithm. Perceptual tests indicate that our algorithm is indeed effective at reducing the amount of motion blur on LCDs.
