Paper Abstract

In this paper, we measured the anisotropic spatio-velocity CSF of human visual system and applied the measured CSF to evaluate motion blur of the LCD. Many Gabor stimuli with different contrasts, spatial frequencies, scroll speeds and angles are displayed on to the LCD and observers are asked whether those stimuli can perceive or not. The thresholds of those stimuli are defined as the contrast that 50% of observers perceive the stimulus. Based on this assessment, we obtained the contrast sensitivity given as the inverse of the threshold. By using the measured spatio-velocity CSFs, we evaluated the anisotropic motion blur characteristics of the LCD.
