PiCTURE
This menu includes all image adjustment settings. Adjustments
that are not available for a given input do not appear on the
menu. For a full listing of the menu, refer to paragraph

ADDITIONAL INFORMATION.
BRighTNESS
Use this control to adjust the darker areas of the picture (black
level), without significantly affecting bright areas. Increasing
the value will give more detail in darker parts of the picture. For
correct adjustment it may prove useful to display a grey scale
with at least twenty bands. Now try to reduce the brightness of
the black band as much as possible while ensuring that it can
still be distinguished from the adjacent band with brightness
slightly higher than black. Alternatively use a scene composed
of black objects alongside other dark coloured objects and try
to keep all the objects separately identifiable.
CONTRAST
Use this control to adjust the image’s white level without affec-
ting its dark areas. For correct adjustment it may prove useful
to display a grey scale with at least twenty bands. Now try to
increase the brightness of the white band as much as possible
while ensuring that it can still be distinguished from the adjacent
band with brightness slightly less than white. Alternatively use a
scene composed of well-lit white objects surrounded by light

objects with lower level lighting, and try to ensure that all the
objects remain separately identifiable.
COLOR
This control (also called Saturation) increases or decreases the
picture colour intensity. When set to zero, colour images will be
shown in black and white. Increase the value until the colours
appear natural: suitable references include skin tones and grass
in landscape shots.
TiNT
Controls the purity of colours. Basically determines the red-green
ratio of the picture.
Decreasing the value increases the red content of the image,
increasing it increases the green. For this adjustment use skin
tones or a test card image with colour bars as a reference.
ShARPNESS
This adjustment serves to modulate the signal to increase or
decrease the level of picture detail.
When the sharpness value is reduced the image details ap-
pear 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 appear unnaturally
clearly defined.
ShARPNESS MODE
This allows you to select the type of processing associated with
sharpness adjustment. For an interlaced or progressive video
signal, set to
VIDEO
; for PC graphics signals, set to
GRAPHICS
.
Sets the system to receive graphics signals rather than video
signals. If the
VIDEO
option is set, it applies Noise Reduction to
increase the clarity of the image. The
GRAPHICS
option deacti-
vates noise reduction.
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
Use this option if the video signal source is a movie film (obtai-
ned from a Teleciné device with 3:2 or 2:2 pull-down). In this
case a deinterlacing algorithm optimized for this type of signal
is applied.
Selecting AUTO mode causes the de-interlacer to analyse si-
gnal characteristics and apply the correct deinterlacing mode
automatically.
