Adaptive Highlight Control
(Auto Knee Mode)
In conventional cameras, only a single knee-point/slope is
available for control over highlights. The BVP-E30 Series,
however, provides multiple knee-points/slopes for superb
overexposure control. The camera detects the highly-lit
areas of a scene and automatically sets and optimises
multiple knee points/slopes accordingly. This allows the
reproduction of extremely difficult images (such as an
interior scene with 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.

Knee Saturation Control
Traditionally, shooting very bright portions of
an object (such as key light reflections from a
person's forehead) can often reduce colour
saturation and change the hue. The BVP-E30
Series adopts a knee saturation control func-
tion in which this 'wash-out' effect on
saturation and hue change is reduced to a
minimum, providing a far more natural colour
reproduction in areas of high light.

Low Key Saturation
With conventional cameras, low-light areas
can be subject to a reduction in saturation.
This can result in the colour in these areas
being "washed out". The low key saturation
function on the BVP-E30 Series eliminates
this problem by optimising the amplification of
colour saturation at low light levels, providing
more natural colour reproduction.

Multi-Matrix Function
The multi-matrix function of the BVP-E30 Series allows colour
adjustments to be applied over the colour range specified by
the operator. The colour spectrum is divided into 16 areas of
adjustment, where the hue and/or saturation of each area can
be modified. This function is especially useful when only the hue
of certain colours needs to be adjusted for special-effects work.
