Liquid crystal displays (LCDs) have shown great promise in the consumer market for their use as both computer and television displays. Despite their many advantages, the inherent sample-and-hold nature of LCD image formation results in a phenomenon known as motion blur. In this work, we develop a method for motion blur reduction using the Richardson-Lucy deconvolution algorithm in concert with motion vector information from the scene. We further refine our approach by introducing a perceptual significance metric that allows us to weight the amount of processing performed on different regions in the image. In addition, we analyze the role of motion vector errors in the quality of our resulting image. Perceptual tests indicate that our algorithm reduces the amount of perceivable motion blur in LCDs.
液晶显示器(LCD)在消费市场中作为电脑和电视显示器展现出了巨大的潜力。尽管它们有许多优点,但LCD图像形成过程中固有的采样保持特性会导致一种被称为运动模糊的现象。在这项工作中,我们开发了一种使用理查森 - 露西反卷积算法并结合场景运动矢量信息来减少运动模糊的方法。我们通过引入一种感知显著性度量来进一步优化我们的方法,该度量使我们能够对图像中不同区域执行的处理量进行加权。此外,我们分析了运动矢量误差在最终图像质量中的作用。感知测试表明,我们的算法减少了LCD中可感知的运动模糊量。
