11.2 Pixel Data Formats for Mono Cameras
11.2.1 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

With the camera set for Mono8, the pixel data output is 8 bit data of the "unsigned char" type. The
available range of data values and the corresponding indicated signal levels are as shown in the
table below.
