Patent ID: 6982752

Claim:
A color correction circuit having at least three color input channel processing circuits, each of said color input channel processing circuits comprising: an adder with a corrected color channel output, a first multiplied input, a second multiplied input, a third multiplied input and an uncorrected color channel input directly coupling the adder to an output of a color image sensor; a noise reduction filter having a filter input coupled to said uncorrected color channel input; an input channel multiplier having an input coupled to an output of said noise reduction filter, an output of said input channel multiplier being coupled to the first multiplied input of said adder; and at least two further multipliers having inputs respectively coupled to outputs of other noise reduction filters forming part of other color input channel processing circuits, one of said two further multipliers having an output coupled to the second multiplied input and other one of said two further multipliers having an output coupled to the third multiplied input.
