ABSTRACT:
A method and a color correction circuit (2) for color correcting a digital color sampled signal. The color correction circuit (2) has three color input channel processing circuits (31,32,33) each of the color input channel processing circuits (31,32,33) has an adder (34) with a corrected color channel output □ a first multiplied input, a second multiplied input, a third multiplied input and an uncorrected color channel input providing for direct coupling the adder to an output of a color image sensor. The processing circuits (31,32,33) have a Low Pass Filter (35,39,40) with a filter input coupled to the uncorrected color channel input. The processing circuits (31,32,33) each also have input channel multipliers (36,42,46) and two further multipliers all having an output coupled to inputs of a respective adder (34,41,45).
