UV MATRIX
The YUV model comprises
luminance
(Y)
and two colour difference (U, V)
components. The luminance can be
computed as a weighted sum of red,
green and blue components; the color
difference, or
chrominance
, components
are formed by subtracting luminance from
blue and from red
The UV representation of chrominance
was chosen over straight Red and Blue
signals because U and V are color
difference signal. These settings allows
you to adjust the colours difference values
to help match the colours on the image to
what they should be in the real world.
For Astronomy use: Experiment
COLOR GAIN
This setting allows you to increase the
colour saturation of the image on the
screen.
For Astronomy use: Experiment
COLOR TONE
Allows you to adjust the colour tone of the
displayed images.
The Red color difference signal is
processed through R-Y and the Blue color
difference signal is processed through B-Y
Y holds the luminance value
