  • Method and arrangement for improving the grayscale resolution of a monochrome monitor
    Patent number: 8154562
    Abstract: A method and an arrangement for improving the digital-signal-generated grayscale resolution of a monochrome visual display unit (3) to which the digital signals from an image source (1) can be supplied over n-bit wide RGB channels (2). Measures are proposed that make it possible to display distinguishable grayscale gradations on the visual display unit (3) regardless of whether a grayscale signal (6; 10) or RGB color signals (12, 13, 14) are transmitted to the visual display unit (3).

  • IMAGE PLAYBACK SYSTEM
    Publication number: 20090251603
    Abstract: An image playback system (3), to which digital R, G, B video signals (R, G, B), respectively via R, G, B line pairs (7, 8, 9), and a communication signal (SDA) may be supplied by an image source (1), includes a program memory (18) in which configuration data for a programmable module (21) are stored, said data being necessary for operation of the image playback system (3). The disclosed system improves how firmware is updated for the image playback system.

  • Method and arrangement for optimizing a luminance characteristic curve
    Patent number: 7576750
    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).
