Correlation between dynamic visual acuity and moving image sharpness evaluation
Masaki Emoto (NHK)
Abstract (in Japanese) (See Japanese page) 
(in English) In current assessments of the quality of television images, the observer's static visual acuity (SVA) must be screened before the subjective evaluation. However, the result of our present work show that the evaluation of moving-picture sharpness was not correlated with SVA but instead with dynamic visual acuity (DVA) for a visual target with a spatial frequency corresponding to a decimal-scale SVA of 0.8. Our results show that viewers with good DVA tend to provide a harsher assessment (i.e., a lower score) of the sharpness of images of moving objects, suggesting that DVA screening is essential before assessment of the sharpness of television images.
