11.3.5 RGB 8 Packed Format
When a color camera is set for the RGB 8 Packed pixel data format, it outputs 8 bits of red, 8 bits
of green, and 8 bits of blue data per pixel. The pixel data result from demosaicing the raw data read
out of the sensor. For each pixel, the raw data were either red or green or blue data due to the
presence of a Bayer filter on the sensor.
For more information about the Bayer filter, see Section 11.3.1 on page 205 .
When a color camera is set for the RGB 8 Packed pixel data format, it outputs 8 bits of red data, 8
bits of green data, and 8 bits of blue data for each pixel in the acquired frame.
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 RGB 8 Packed output.
The following standards are used in the table:
P
0
= the first pixel transmitted by the camera
P
n
= the last pixel transmitted by the camera
B
0
= the first byte in the buffer
B
m
= the last byte in the buffer
With the camera set for RGB 8 Packed, 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.
