3.2.7 Detail
This setting sets up the level of fine image-detail processing the VLS-2000 performs,
on a scale of 0 to 10. The nominal setting is 5, but edges can be sharpened with higher
numbers, or softened with lower numbers.
3.2.8 Noise
This setting controls the amount of noise filtering performed by the VLS-2000, on a
scale of 0 to 10. The 5 setting provides nominal filtering. For broadcast or cable
sources, more filtering may be preferable, while high quality sources, such as DVD or
Laser disc may be better viewed at lower settings.
3.2.9 Motion
This setting controls the type of motion processing performed by the VLS-2000. This
should be set to
Auto
except for some limited cases. The VLS-2000 has sophisticated
processing hardware which, in automatic mode, continuously analyzes the content of
the video signal and optimizes the processing to provide the best viewing experience.
The Auto mode switches between three different types of processing (Video, Film, and
Still). The additional settings on this control simply limit the switching of algorithms.
If set to
Video,
the information from successive interlaced frames is combined with
motion processing to compensate for the movement of objects in the picture during the
frames. This setting is used for video originating from video cameras, which capture
images at 60 frames per second, then transmitting the information ½ frame at a time.
Most home and TV network originated video is of this type.
If set to
Film,
the information from successive frames is reconstructed to exactly
match the original movie film frames. This reconstruction is made possible by
advanced logic in the VLS-2000 which detects and reverses the “3:2 pulldown”
process used to convert movie film timing to video timing.
If set to
Still
, the information from successive frames is combined and sharpened with
no motion estimation. This gives the sharpest possible picture, but will result in
visible artifacts on moving objects.
If set to
Vid/Flm
, the automatic switching logic is prohibited from switching to Still
mode. This should only be used for known Film sources, and eliminates the occasional
switch into and out of static mode during still portions of the film.
If set to
Vid/Stl
, the transition to Film mode is prohibited. This may be used for the
output of digital cameras or home video cameras, but otherwise, needlessly prohibits
the best possible motion processing from activating if a Film source is detected.
3.2.10 Black
This setting enhances the black level for home theater viewing. Use the
Enhance
setting to eliminate any remaining dark grey on the edges of black scenes.
Normal
is
used if this enhancement has already been performed at the input source (i.e. the DVD
source has already had Black Level Enhancement set)
