Video Image Controls

The following properties for the Video Digitisation can be modified:

Brightness

Brightness is the relative lightness or darkness of the colour, usually
measured as a percentage from 0 (black) to 255 (white).
The default value is 128.

Contrast

Contrast is the brightness ratio of the lightest to the darkest part of the
television screen image with values between 0 and 255.
The default value is 128.

Saturation

The saturation indicates the strength or purity of the colour (sometimes called
chroma). It represents the amount of grey in proportion to the hue, measured
as a percentage from 0 (grey) to 255 (fully saturated). On the standard colour
wheel, saturation increases from the centre to the edge.
Colours appear more "pure" with increased saturation and more "washed-out"
with decreased saturation.
The default value is 128.

Hue

Hue is the colour reflected from or transmitted through an object. It is
measured as a location on the standard colour wheel. Values are between 0
and 255, representing a degree between 0° and 360° on the colour wheel. In
common use, hue is identified by the name of the colour, such as red, orange,
or green.
The default value is 0.
