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.
In recent years, several methods for evaluation or quantification of video image quality have been studied, such
as MPRT (Moving Picture Response Time) for quantification of motion blur occurred on hold-type displays.
It is required to improve the methods or criteria to consider human visual characteristics, especially anisotropy
and spatio-temporal dependency of contrast sensitivity. In this study, we quantify motion blur of the display by
comparing it with static blur edge. We examine the influence of conditions for edge presentation, such as moving
speed and moving direction of the edges, on perceived blurriness. According to the results of the assessment, we
found that the anisotropy of the display had a significant influence on perception of motion blurs. This result
suggests that multidirectional measurement is required to improve criteria of motion blur.
