A method and an arrangement for improving the digital-signal-generated grayscale resolution of a monochrome visual display unit () to which the digital signals from an image source () can be supplied over n-bit wide RGB channels (). Measures are proposed that make it possible to display distinguishable grayscale gradations on the visual display unit () regardless of whether a grayscale signal () or RGB color signals () are transmitted to the visual display unit ().

Method and arrangement for improving the grayscale resolution of a monochrome monitor

A method and an arrangement for optimizing the luminance characteristic curve for a display system using a lookup table. Digitized video levels are supplied to this lookup table and are optimized using correction values stored in the lookup table. With suitable means, the luminance characteristic curve can be easily adapted to standards and/or custom specifications. The memory requirement is low, since it is not necessary to provide different lookup tables for different ambient luminosities or selected reproduction models (curves).
