Compander Black Level Slope: 0 - The values of “0” to “64” in a 13 bit repre-
sentation are set to “offset1” in a 10 bit representation. Offset1 can be set in
4
comp_linear
register 33h.
1 - In this case the black level is mapped linearly from 13 bit values to 10 bit
values. “64” is mapped into “8”. All the other values between “0” and “64” are
divided by 8 in order to get the 10 bit representation. (See Figure 13)
