Recent developments in video technology enable us to view wider field of view (FOV) images using wide flat panel displays as one would a television monitor. New video systems with high resolution beyond HDTV have been proposed, but it is not clear that the motion picture quality is sufficient if utilizing traditional video system frame rates. In the assessment of picture quality, it is recommended to screen viewers' static visual acuity (SVA), but not dynamic visual acuity (DVA). Furthermore, the methodology to measure the DVA appropriate for the participants in the assessment of picture quality has not yet been established. We experimentally studied the changes in DVA performance by looking at differences in conditions in measuring DVA, as the first step to establish the methodology. We successfully verified the improvement of DVA performances in binocular viewing compared to monocular viewing. We also looked at the differences in DVA performance by the shape of the visual target (Landolt C or E chart).
