Mono 12 Format

When a monochrome camera is set for the Mono12 pixel data format, it outputs 16 bits of brightness
data per pixel with 12 bits effective. The 12 bits of effective pixel data fill from the least significant
bit. The four unused most significant bits are filled with zeros.
The table below describes how the pixel data for a received frame will be ordered in the image buffer
in your PC when the camera is set for Mono12 output. Note that the data is placed in the image
buffer in little endian format.
The following standards are used in the table:
P = the first pixel transmitted by the camera
0
P = the last pixel transmitted by the camera
n
B = the first byte in the buffer
0
B = the last byte in the buffer
m
Byte Data
B Low byte of brightness value for P
0
