ABSTRACT
This chapter discusses the literature pertaining to display color, in order to identify those concepts and techniques that have achieved general recognition across the several user communities. Information concerning color control in digital displays has appeared in publications addressed to audiences in widely varying specialties, including color science, optics, visual physiology, psychophysics, color perception, display engineering, computer graphics, electronic image processing, and machine vision. Color systems made up of reflective color samples have a long history and abiding usefulness. The image-computation stage may also include image processing to improve perceptibility of information in the image, to compress the information for electronic transmission, or to “segment” the image into figure-ground units for machine vision. Nonlinearity of the luminance–voltage relation produces variation in the amount of luminance resolution available over the operating range of each cathode-ray tube phosphor. Variable luminance resolution can have important consequences for image quality.
