LSC in TDA4x/AM6xA VPAC-VISS can support independent color shading correction.
Each color channel (e.g., in RGGB) may have its own shading property and image center location.
The following Matlab script may take a text file for input of lens shading property and calculate the 2D LSC LUT.
function gen_lsc_lut(spec_file, pitch_in_mm, W, H, hc, vc, N, Q, lut_out)
% spec_file LSC shading property file
% pitch_in_mm sensor pixel pitch
% W image width
% H image height
% hc horiztonal image center (1x1 or 4x1)
% vc vertical image center (1x1 or 4x1)
% N LSC LUT down-sampling factor (8, 16, 32, 64, or 128)
% Q LSC LUT integer encoding format (5, 6, 7, or 8) with +1
% lut_out output 2D LSC LUT text file
% read lens shading spec file
spec_lut_4c = read_spec(spec_file, pitch_in_mm);
% calculate LSC LUT table size
h_end = ceil(W / N) * N;
v_end = ceil(H / N) * N;
[xx, yy] = meshgrid(0:N:h_end, 0:N:v_end);
g_tbl_4c = zeros([size(xx,1), size(xx,2)*4]);
for i = 1:4
r = sqrt ((xx - hc(i)).^2 + (yy - vc(i)).^2);
r = min(r, spec_lut_4c(end, 1));
% calculate LSC LUT
gain = interp1(spec_lut_4c(:,1), spec_lut_4c(:,i+1), r);
g_tbl_4c(:,i:4:end) = round ((gain - 1) * 2^Q);
end
g_tbl_4c = min(255, max(g_tbl_4c, 0));
% write LUT into a text file with 4 color channels
dlmwrite(lut_out, g_tbl_4c, 'delimiter', ' ');
% read spec file for 4 colors in 5 columns
function [spec_lut_4c] = read_spec(spec_file, pitch_in_mm)
spec_lut = dlmread(spec_file);
spec_lut_4c = zeros(size(spec_lut,1), 5);
if size(spec_lut, 2) == 5
spec_lut_4c = spec_lut;
elseif size(spec_lut, 2) == 2
spec_lut_4c(:,1:2) = spec_lut;
spec_lut_4c(:,3) = spec_lut(:,2);
spec_lut_4c(:,4) = spec_lut(:,2);
spec_lut_4c(:,5) = spec_lut(:,2);
else
error('spec lut file format is wrong');
end
spec_lut_4c(:, 1) = spec_lut_4c(:, 1) / pitch_in_mm;
for i = 2:5
spec_lut_4c(:, i) = spec_lut_4c(1, i) ./ spec_lut_4c(:, i);
end
The lens shading spec file may have 2 or 5 columns (for color independent shading and color dependent shading).
The first column is for distance from image center for shading (scaled by the pitch_in_mm) and the other columns are for the amount of shading.
In the example below, the first column is in the unit of pixels (i.e., pitch_in_mm=1) and the other columns are the same for all RGGB colors for simplicity.

If you use the DCC tuning tool for LSC tuning, you may see that the tool only supports color-independent input (i.e., the LUT above has only 2 columns rather than 5).
You may use the tuning tool to generate a valid xml file with the first 2 columns of above LUT.
Then you may use the 2D LSC LUT from matlab/octave code above to replace 2D LUT inside the xml file.
That will make your LSC xml file color dependent.
Note
If you are working with a WDR sensor with more than 16-bit dynamic range, there is a pre-gamma compression applied to the raw image pixels.
For LSC 2D LUT, the gain values has to be gamma corrected in the same way.
You would have to adjust your LSC shading values with the same gamma value.
e.g., 0.9 (10% loss) with 0.5 gamma becomes "0.9^0.5 = 0.94868".
