7.13.19 PixelFormat
Format of the pixels provided by the device. It represents all the information provided by
PixelCoding, PixelSize, PixelColorFilter combined in a single feature.
General Information
RAW: Raw data format. Here the data is stored without processing.
Bayer: Raw data format of color sensors.
Color lters are placed on these sensors in a checkerboard pattern, generally
in a 50% green, 25% red and 25% blue array.
Mono: Monochrome. The color range of mono images consists of shades of a single
color. In general, shades of gray or black-and-white are synonyms for mono-
chrome.
RGB: Color model, in which all detectable colors are dened by three coordinates,
Red, Green and Blue.
Red
Green
Blue
Black
White
The three coordinates are displayed within the buffer 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 different values for each
color channel. Mostly this will be 8 bit, which means 2
8
different "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 cameras. In this formats, the un-
used bits of one pixel are lled with data from the next pixel.
