Modeling motion-induced color artifacts from the temporal step response

LCD motion blur is a well-known phenomenon, and a lot of research is attributed to characterize and improve it. Until recently, most studies were focused on explaining the effects visible in black-and-white patterns, and hence color effects were ignored. However, when a colored pattern is moving over a colored background, an additional motion-induced artifact becomes visible, which is referred to as chromatic aberration. To describe this phenomenon, our model to characterize the appearance of moving achromatic patterns is extended in such a way that it now calculates the apparent image from the temporal step response of the individual primary colors. The results of a perception experiment indicate that there is a good correspondence between the apparent image predicted with the model and the actual image perceived during motion. © Copyright 2007 Society for Information Display.
