<p>A digital display system including a memory containing digital representations of a three color component color image connected through a network of look-up tables and summing circuits to the red, green and blue display drivers of a suitable display. In particular, a first summing circuit is connected to the red display driver, a second summing circuit is connected to the green display driver, and a third summing circuit is connected to the blue display driver. Three look-up tables are connected to the red digital representation in memory with one of the look-up tables being connected to the first summing circuit, another of the look-up tables being connected to the second summing circuit and the third look-up table being connected to the third summing circuits. In a similar manner, groups of three look-up tables are connected to the green and blue digital representations and each look-up table of each group in turn connected to a different summing circuit. The result is nine look-up tables cross-coupled to three summing circuits to provide selected color adjustments and transformations.</p> |
