Abstract

Embodiments relate to circuitry for pixel conversion of images for display. A circuit converts input pixel values of an image using a color conversion function. A lookup table memory circuit stores a mapping of color converted values and input pixel values where the mapping represents the color conversion function. The circuit produces a color converted value from the lookup table as a color converted version of a first input pixel value responsive to the first input pixel value being within a first range. The circuit may also produce a color converted version of a second input pixel value by interpolating a subset of the color converted values received from the lookup table responsive to the second input pixel being within a second input range.
