A major problem in the subjective evaluation of TV image quality is individual variability among participants. The large individual differences in the susceptibility to image blurring result in imprecise evaluations and loss of power to detect statistically significant differences between experimental conditions. In image quality assessments of traditional televisions, the observers' visual acuities (VA) should be screened. For emerging TV systems with wide field-of-view (FOV), in which objects move quickly relative to the display frame, it is unclear whether screening viewers' VAs is sufficient or not. In the wide FOV TV image quality evaluations, screening of the dynamic visual acuity (DVA) might be effective to control for the individual differences. We show here that a significant correlation between the number of blurred frames reported and the observer's DVA. Therefore, DVA screening is important to avoid an imprecise evaluation and to detect statistical significance between experimental conditions.
