Evaluation of Motion Blur in LCD.(1)

Relation between Parameters of Motion Blur Visual Charasterstics.

Abstract

Motion blur in LCD is caused by the response of liquid crystal and hold-type driving method. Moving Picture Response Time (MPRT)1) ,which is one of the basic psychophysical estimation, measures an average width of blurs. This method comprehensively evaluates the causes of the blur. However we found that visualization of the blur is expressed not only the width but color, sharpness of object and ratio of blur area. We evaluated and analyze the relation between visualization of the motion blur and physical properties (image properties and panel characteristics) at a CRT display and several types of LCDs, and performed subjective evaluation with various images.
