RGB:
Color model, in which all detectable colors are dened by three coordinates,
Red, Green and Blue.
Red
Gree
n
Blue
Black
White
The three coordinates are displayed within the bu󰀨er in the order R, G, B.
BGR: At BGR the interface of the camera mirrors the order of transmission of the color
channels from RGB to BGR.
This can save processing power on the computer, because these data can be
processed by the graphic card without conversion.
Pixel
depth:
In general, pixel depth denes the number of possible di󰀨erent values for each
color channel. Mostly this will be 8 bit, which means 2
8
di󰀨erent "colors".
For RGB or BGR these 8 bits per channel equal 24 bits overall.
Two bytes are needed for transmitting more than 8 bits per pixel - even if the
second byte is not completely lled with data. In order to save bandwidth, the
packed formats were introduced to Baumer CX cameras. In this formats, the
unused bits of one pixel are lled with data from the next pixel.
8 bit:
Byte 1 Byte 2 Byte 3
12 bit:
Byte 1 Byte 2
unused bits
Packed:

The camera must be stopped before PixelFormat can be set.
