Abstract

Color matrix displays (CMD’s) constitute a new generation of high-resolution, two-dimensional sampled visual display devices. We describe a CMD image-simulation system and a series of psychophysical image-quality experiments to investigate basic visual parameters of sampled displays. For binary CMD’s, a RGBG pixel mosaic was found to produce imaging superior overall to that of the more-conventional RGB mosaics. For CMD’s with gray-scale capability, a discrete approximation of a Gaussian band-limiting line-spread function dramatically improved CMD image quality for all pixel mosaics. Across the six image colors tested, image quality for band-limited CMD images approached asymptotic levels at approximately 3000 pixels deg−2 and eight gray levels, regardless of the pixel mosaic. The results are interpreted within the context of contemporary views of human visual system channel structure and elucidate the role of applied-vision studies in advanced display systems design.
