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)
Offset
Additionally adjustable
“Brightness” for this color separation
(-
255… 0 +255 in 10Bit area)
(x, y)
Number of pixels within a line or column
Vid Brightness Out(x,y)
Output of this step (area 0…1023)
