ABSTRACT:
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).
