ABSTRACT:
A color image processing device includes a pre-correction unit, a computation processing unit and a post-correction unit. The pre-correction unit includes a pre-correction circuit which carries out a pre-correction to reverse a highest-order bit of a pixel value on input data of a color component. The pre-correction unit selectively outputs the input data of the color component or the data of the color component pre-corrected by the pre-correction circuit according to the color component. The computation processing unit carries out a prescribed computation processing on the data of the color component output by the pre-correction unit and outputs the data of the color component carried out with the prescribed computation processing. The post-correction unit includes a post-correction circuit which carries out a post-correction to reverse a highest-order bit of a pixel value on the data of the color component output by the computation processing unit. The post-correction unit selectively outputs to a prescribed output destination according to the color component, the data of the color component output by the computation processing unit or the data of the color component post-corrected by the post-correction circuit.
