Knee Saturation
Traditionally, very bright parts of a scene
(such as key light from a person’s forehead)
suffer from a loss of saturation or a change in
hue. The HDC-1000 family provide a ‘Knee
Saturation’ function, which can counte-
ract this effect and achieve a more natural
appearance in these difficult areas.
Selectable Gamma Table
The selectable gamma table provided with
the HDC-1000 Series cameras allows users
to create a specific look for a picture by
selecting from a choice of fixed gamma
patterns.
Variable Black Gamma
The Variable Black Gamma function
for the HDC-1000 Series of cameras allows
for fine adjustment of tonal reproduction in
the shadow area. This feature can help to
bring out details from the dark parts of the
picture without affecting mid-tones while
maintaining the absolute black level.

Low-key Saturation
With conventional cameras, low light areas
can be subject to a reduction in saturation.
This can result in colours in those areas being
lost. The Low-Key Saturation function on the
HDC-1000 Series of cameras eliminates this
problem by optimising the amplification of
colour saturation at low light levels, providing
more natural colour reproduction.
