1. A computer method in determining a pixel display pattern from a pixel given pattern using a transform, comprising the steps of: (A) enhancing obtained input information into output information, thereby furthering progress towards: (a) for at least one display attribute, the transform meeting at least one constraint, and (b) for at least one substantially uniform background luminance value and subject to the at least one constraint, the transform being such that, if the pixel display pattern is displayed against the substantially uniform background, visual distortion as compared with the pixel given pattern is minimized; and (B) forwarding the output information for one of (i) further enhancement and (ii) display of the pixel display pattern.
