Abstract

of the image sensor is moved at the same velocity vc as in the foregoing observation to capture an image of a static pattern PE, and a blur width W along the scrolling direction that appears in a distribution profile of the captured image is observed. Based upon the blur width W and the exposure time of the image sensor for capturing the image of the static pattern PE, the moving velocity of the test pattern at the time of observation of the BEW is estimated, and by using the moving velocity, the BEW is normalized. Evaluation of the moving image quality of the screen is carried out by using the normalized N BEW. The moving velocity of the original test pattern can thus be estimated easily and accurately, and accordingly, the moving image quality of the screen can be evaluated accurately.
