Pixel depth: In general, pixel depth denes the number of possible different values for
each color channel. Mostly this will be 8 bit, which means 2
8
different "col-
ors".
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.
