Abstract:
1. An image processing method comprising: receiving input color image data representing an initial color of a to-be-rendered pixel where the received color image data comprises at least first, second and third primary color data values defining an initial to-be-rendered color of the pixel; determining if the initial to-be-rendered color has a minimum one among the received at least a first, second and third primary color data values and larger others of the primary color data values and, if so, identifying the minimum one color data value of said received at least first, second and third primary color data values; and computing a substitute and higher color data value for said minimum one color data value; wherein the image processing method computes said substitute and higher color data value as a function of two or more variable gain values, where a first of the variable gain values decreases as the value of the identified minimum one color data value increases and where a second of the variable gain values increases as the value of a corresponding received and larger color data value of a corresponding one of the larger others of the primary color data values increases.
