Could any one tell me the principle of the CFA in dm6437 ???

I know the bayer pattern and color filter array.

I just don't understand the value in the CFA coefficient means !!!

#define R_PHASE \
    0,   0,    0, 0, \
0,   64,   0, 0, \
0,   0,    0, 0, \
0,   0,    0, 0, \ etc....

#define GR_PHASE \
    -8, 0,   -8, 0, \
32, 32,   32, 0, \
-8, 0,   -8, 0, \
0,   0,    0, 0, \..etc....

#define GB_PHASE \
-8, 32, -8, 0, \
0, 32, 0, 0, \
-8, 32, -8, 0, \
0, 0, 0, 0, \...etc...

#define B_PHASE \
    16, -6,    16, 0, \
6, 0,     6, 0, \
16, -6,   16, 0, \
0,   0,    0, 0, \....etc

..............

I would like to know the principle ,maybe provide me some document link...etc...

Thank you

Best regard

I assume you are talking about the values loaded into the RGB2RGB Blending Matrix Coefficient Registers. Look at spru977 (I have version d, section 6.2.19) for a description of the values. Basically they are S12Q8 format blending coefficients used for Bayer interpolation.

Do you know the principle now?
I have the same confusion with you.
I have read the answer the others had replied,but I don't think the it was right.
CFA Interpolation is a different with GRB2GRB Blending, so GRB2GRB Blending's register can't make CFA Interpolation work.
If you have understood the principle ,can you tell me?
Thank you very much
