An image scanning device, including CCDs provides digital color image data representing an image. A 3-by-3 matrix multiply logic is connected to the image scanning device for modifying or transforming the intensities of each individual color encoded in the digital color image data. The matrix multiply logic has a multiplier and an accumulator. The multiplier provides intermediate products by performing one-stage multiplications between the intensity values for each pixel and the coefficients of the 3-by-3 matrix. The one-stage multiplications are time multiplexed. The accumulator accumulates the intermediate products from the multiplier for each pixel to thereby provide optimized color values for each pixel. The multiplier implements specialized adders to perform the one-stage multiplications.
