Mono 8 Format

When a monochrome camera is set for the Mono 8 pixel data format, it outputs 8 bits of brightness
data per pixel.
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 Mono8 output.
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
