An extended overdrive table uses the saturation regions to store useful data that conformably extends the unsaturated region in a natural way. This extended overdrive table reduces the size of any interpolation errors when straddling crossover points to acceptable levels without requiring storing or using any crossover data. In addition, since the saturation regions are used to hold the new data, no additional storage requirements are introduced. The numeric range of the extended table is increased and it is therefore supposed that the bit depth of the table entries is increased, but the table can be resealed to retain the original bit depth with insignificant loss of accuracy. Also, the new data incorporated into the saturation regions allows run time calculation of the pixel attained at the end of the frame time that is needed as the start of the pixel for the next cycle.
