the picture colour intensity. When set to zero, colour images
will be shown in black and white. Increasing the value, try to
find the point at which the colours look natural: suitable
references include skin tones and grass in landscape shots.
TINT
Controls the purity of the colours. Basically determines the
red-green ratio of the picture.
Reducing the value will boost the red contents of the picture,
increasing the value will boost the green tones. For this
adjustment use skin tones or a test pattern image with colour
bars as a reference.
SHARPNESS
Use this adjustment to increase and decrease the level of
picture detail.
When the sharpness value is reduced the image details
appear less pronounced, while increasing the value raises
image definition, making the outline of objects sharper.
Note that an excessively high value may result in a ‘noisy’ picture
and the edges of objects may be unnaturally defined.
SHARPNESS MODE
This allows you to select the type of processing associated
with sharpness adjustment. In the case of a progressive or
interlaced video signal
VIDEO
mode is advisable; with PC graphic
signals use
GRAPHIC MODE
.
FILTER
This allows you to select the mode in which the input signal
is processed. Selecting the most appropriate value for a given
input signal ensures the best horizontal and vertical definition
and makes the picture sharper.
CINEMA MODE
In
AUTO
the deinterlacer recognises if the video signal source
is a movie film (obtained from a Telecine device with 3:2 or 2:2
pull-down) and applies a deinterlace algorithm optimised for this
type of signal.
If the video signal source is not identified as a film, or if you
select
NO
the deinterlacer applies a Motion compensated
algorithm optimised for video camera signals.
VIDEO TYPE
Activates a filter to improve stability of pictures from video
recorders or DVD players. To toggle between
NORMAL, VCR1
mode and
VCR2
mode press on the remote control.
NOISE REDUCTION
This adjustments allows to choose the filter value for noise
reduction purposes.
As soon as this option is selected on the menu, the image is
divided in two parts.
In the left side the image is not altered by the filter, in the right
part the filter is activated.
This allows you to compare the effect of the filter.
It is possible to deactivated the filter (
NOT ACTIVE
), to use the
automatic adjustments (
AUTO
) or to manually select (
MANUAL
)
the value suitable for the image with the
VALUE
adjustment.
In case of using the
VALUE
adjustement, it is enoght to select to
cursor below and set the value with the / keys of the remote
control.
Associated to the
NOISE REDUCTION
there is the possibility to use the
specific function
(FLESH TONE CORRECTION)
to make skin tone more
natural. Often the use of noise reduction filter slightly degrades
the image in those areas where skin tones are visible. With the
use of this function it is possible to maintain an excellent image
quality throughout the entire projected image.
