BRIGHTNESS

Use this control to adjust the darker areas of the picture
(black level), without 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 ensure that all the objects can
be separately identified.

CONTRAST

Use this control to adjust the images white level without affect-

ing 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 can be separately identified.

COLOUR

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: suit-
able references include skin tones and grass in landscape
shots.

TINT

This adjustment controls the purity of colours. Basically it

determines the red-green ratio of the picture. Decreasing

the value increases the red content of the image, increasing

it increases the green content. 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 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 appear unnaturally

clearly defined.

SHARPNESS MODE

This allows you to select the type of processing associated

with sharpness adjustment. For an interlaced or progres-

sive video signal, set to Video; for PC graphics signals, set

to Graphics.

If the VIDEO option is set, it applies Noise Reduction to

increase the clarity of the image.

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

(obtained from a Telecin device with 3:2 or 2:2 pull-down).

In this case a deinterlace algorithm optimised for this type

of signal is applied. Selecting AUTO mode causes the de-

interlacer to analyse signal characteristics and apply the

correct deinterlace mode automatically.
