Contrast Control
The controls in this menu permit the user to alter the “contrast” of
the image. This control mimics the operation of the ”contrast”
control in CRT video monitors by linearly adding gain to the image.
This is often helpful in making obscure detail become more visible
and compensating for poor or harsh lighting conditions. Since a
video image is made of the primary optical colours, red, green and
blue, these colours may be individually adjusted, or all may be
adjusted together. Individual adjustment is also useful for altering
the colour balance of an image, to compensate for (or imitate)
coloured ambient illumination.
`
Invert Control
This control permits the user to invert the colours of the image, like
a photographic film negative. Although this dramatically alters the
appearance of the image, it is sometimes helpful in making an
obscure detail become more visible. Since a video image is made
of the primary optical colours, red, green and blue, these colours
may be individually inverted, or all may be inverted together.
`
Image Control
In the colour models of i--SPEED 2 , this control enables the user to
convert the colour image to monochrome (black and white). This is
sometimes useful to make the image clearer when bright colours in
the scene are cluttering the image.
`
Reset Control
All of the image processing functions, including Enhance,
Brightness, Contrast, Invert and Image may be applied to the
picture simultaneously. It is therefore possible to lose track of
which controls have caused what effects, so a reset control is
available to set Brightness, Contrast, Invert and Image to their
default values.
