8.1.2. Pixel Format

On Baumer digital cameras the pixel format depends on the selected image format.
8.1.2.1.
Definitions
RAW:
Raw data format. Here the data are stored without processing.
Bayer:
Raw data format of color sensors.
Color filters 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  defined  by  three  coordinates, 
Red, Green and Blue.
The three coordinates are displayed within the buffer in the order R, G, B. 
BGR:
Here the color alignment mirrors RGB.
YUV:
Color model, which is used in the PAL TV standard and in image compression.
In YUV, a high bandwidth luminance signal (Y: luma information) is transmitted 
together with two color difference signals with low bandwidth (U and V: chroma 
information). Thereby U represents the difference between blue and luminance 
(U = B - Y), V is the difference between red and luminance (V = R - Y). The third 
color, green, does not need to be transmitted, its value can be calculated from
the other three values.
YUV 4:4:4
Here each of the three components has the same sample rate.
Therefore there is no subsampling here.
YUV 4:2:2
The chroma components are sampled at half the sample rate.
This reduces the necessary bandwidth to two-thirds (in relation to 
4:4:4) and causes no, or low visual differences.
YUV 4:1:1
Here the chroma components are sampled at a quater of the
sample  rate.This  decreases  the  necessary  bandwith  by  half  (in 
relation to 4:4:4).
