2.9 DATA OUTPUT FORMAT
2.9.1 Bit Depth
The internal camera processing of the CCD data is performed in 14 bits. The camera
can output the data in 14, 12, 10 or 8 bit format (3x8 RGB for B0610, B1410 and
B1610 ONLY). During this standard bit reduction process, the least significant bits
are truncated – Figure 2.21.
-
“14-bit” –
All original bits D0 (LSB) to D13 (MSB) are used. This mode is
available only for Single Output.
-
“12-bit” –
If the 14 bit original camera data is D0 (LSB) to D13 (MSB), and
camera is set to output 12 bit data, the 12 output bits are mapped to D2 (LSB) to
D13 (MSB).
-
“10-bit” –
If the 14 bit original camera data is D0 (LSB) to D13 (MSB), and
camera is set to output 10 bit data, the 10 output bits are mapped to D4 (LSB) to
D13 (MSB).
-
“8-bit” –
If the 14 bit original camera data is D0 (LSB) to D13 (MSB), and
camera is set to output 8 bit data, the 8 output bits are mapped to D6 (LSB) to
D13 (MSB).

“
3 Tap RGB
” – In this mode each pixel is sent in 24 bit format (3 x 8 bit RGB),
starting with the first pixel of the first line and ending with the last pixel of the
line. Each pixel consists of three components R (red), G (green) and B (blue),
