Low-key Saturation Function
With conventional cameras, low light areas can be subject to a reduction in
saturation. This results in under-saturated colors in those areas. The Low-key
Saturation function on the HDC-2000 Series eliminates this problem by
optimizing the amplification of color saturation in low light areas, providing
more natural color reproduction.
Low-key Saturation OFF

HyperGamma is a set of transfer functions designed to provide powerful contrast.
These functions are simply accessed via the setup menu, and you can select one
of the four types of curves according to your needs and conditions. For example,
you can select to enhance natural reproduction in low-key areas, to achieve
greater flexibility in wide dynamic scenes.

gamma creation software running on a Microsoft Windows PC, and then
quickly load them onto HDC-2000 Series cameras via a USB memory stick or an
MSU/RCP using Memory Stick Duo. The software has an easy-to-use GUI that
allows the gamma curve to be visually edited simply by plotting the x and y
values of each point of the curve.
