Assessment to Determine Format for a UDW Television
A system format that optimizes viewer appreciation of Ultrahigh-Definition and Wide-screen (UDW) images was investigated; in particular, the relationships among the screen size, viewing distance (angle), screen aspect ratio, and the number of pixels. A linear relationship was found between the screen size and preferred viewing distance. Comparison of the preference for images with four aspect ratios and with 16:9 aspect ratio showed that the preferred aspect ratio depends on the screen size, not the viewing angle, with about 2:1 most preferred in the home environment. The relationship between the screen size and aspect ratio was thus given by a simple equation. An equation for relating the maximum number of pixels necessary for a UDW system to three parameters (screen size, viewing distance, and aspect ratio) was derived using the visual resolution capacity.
