Figure 6-86 shows the local image intensity to noise threshold T_n mapping via the 12-segment interpolated lookup. Twelve sets of (X, Y, S), S = slope, are provided per curve, one set per color plane, with the first X coordinate fixed at zero.
Figure 6-86 NSF4V Local Image Intensity to Noise Threshold Piece-wise Linear FunctionThe slopes should be implemented with signed value, as some image sensors might require higher noise threshold at the low intensity range than high intensity range.
