Use the
Analog Interface
sub-menu/box to display or configure the analog input video-signal
interface card (CV). Configuration of these parameters is saved automatically and does not
require access to the
Save
menu.
The
Analog Interface
sub-menu/box comprises the following parameters:
■
Luminance Gain
– The
Luminance Gain
parameter controls the amount of digital gain applied
to the luminance signal. This parameter influences the contrast of the picture – the larger the
gain, the higher the contrast. The range is 0 to 255. Default value is
128
.
■
Luminance Offset
– The
Luminance Offset
parameter controls the amount of digital offset
applied to the luminance signal. This parameter influences the brightness of the picture – the
larger the offset, the darker the image. The range is 0 to 255. Default value is
128
.
■
Chroma Gain
– The
Chroma Gain
parameter controls the amount of digital gain applied to the
chrominance signal. This parameter adjusts the saturation of the picture, for example, from
pink to red. The range is 0 to 255. Default value is
128
.
■
Chroma Phase
– The
Chroma Phase
parameter controls the amount of chrominance phase
(Tint). This parameter influences the hue of the picture. The range is 0 to 255. Default value is
128
.
NOTE:
Chroma Phase is relevant only for NTSC format.
