Prior to the final output of the C1-C4 FIR Filter there is a scaling and offset addition.
That is the sum of the selected coefficients (derived from the intensity, gradient logic and controls above) times the pixel values is then sent through a scaling multiplier U14Q8 and then added an offset U16.
