If the camera is set to output 8-bit data, the image sensor most significant
data bits [D4 to D11] are mapped to D0 (LSB) to D7 (MSB)
-
“10-bit” digitization (See Figure 2.13)
If the camera is set to output 12-bit data, the image sensor data bits are
mapped to the D2 (LSB) to D11 (MSB) output bits and output bits D0
and D1 are set to zero.
If the camera is set to output 10-bit data, the image sensor data bits are
mapped directly to D0 (LSB) to D9 (MSB)
If the camera is set to output 8-bit data, the image sensor data most
significant data bits (D2 to D9) are mapped to D0 (LSB) to D7 (MSB).
