Near white color correction

In a color image processing system (1) , near-white color corrections are performed prior to printing (8) to improve the dynamic range of the printed image. Input pixels are compared with a threshold (71) and if less than, a dithering is performed to determine the output value. Dithering takes place...

Summary:In a color image processing system (1) , near-white color corrections are performed prior to printing (8) to improve the dynamic range of the printed image. Input pixels are compared with a threshold (71) and if less than, a dithering is performed to determine the output value. Dithering takes place to determine if the output value is to be the threshold or zero.
