Take notice
that using “Brightness” causes a digital offset in the image data:
Vid Brightness Out(x,y) = (VidIn(x,y) + Offset)

VidIn(x,y) Pixel-normalized image after the shading correction
(0...2047 in 10Bit area
= 0… 2,0 relative)

Offset
Additional adjustable “Brightness” for this color separation
(-
255… 0 +255 in 10Bit area = -0,25…0…+0,25 relative)

(x, y) Number of pixels within a line or column

Vid Brightness Out(x,y)
Output of this step (area 0…1023)
