Natural Color Reproduction with
"Knee Saturation Control"
Traditionally, shooting very bright portions of an object
(such as key light reflections from a person's forehead)
can reduce color saturation and change the hue in
highlight areas.
The DXC-D50/D50WS cameras adopt a Knee
Saturation Control function in which this 'washed-out'
effect on saturation and hue change is reduced to a
minimum, and far more natural color reproduction in
highlight areas is achieved.
Adaptive Highlight Control
In conventional cameras, only a single
knee-point/slope is available for contrast control
over highlights. The DXC-D50/DXC-D50WS
camera, however, provides multiple
knee-points/slopes for superior overexposure
control. The camera analyzes the highlight
areas of a scene and automatically sets and
optimizes multiple knee points/slopes
accordingly. This allows the reproduction of extremely
difficult images (such as an interior scene that includes
a brightly sunlit window) with much more overexposure
latitude. This function applies only to input video levels
in excess of the knee point - the middle and low
luminance parts of the video signal are unaffected by
this control.
