An interlaced input consists of two fields separated in time. Both fields are
required in order to make up the full resolution input image, but since they are
sent one after the other, a moving image will have “motion artifacts” if the two
fields are simply combined together. The most common artifact is a blurring
at the point of maximum movement within an image. Your unit provides some
tools to minimize the effects of de-interlacing of an image.
The following options are available for this menu item:
Mode Function
Normal/weave The two interlaced fields are simply combined/weaved
together. This will often show artifacts on moving images,
but can be used when the input is known to be still.
Auto Automatically selects Film 3:2 or Medium Range Motion
Compensation (M. Comp Med.) depending on whether Film
Mode is detected or not.
Film 3:2 Enables 3:2 pull down conversion of the incoming NTSC
video. (This option should not be used if the source is not
NTSC video).
M. Comp Low
M. Comp Med.
M. Comp High
Enables Pixel Adaptive Motion Compensation. Three levels
are available with ‘Low’ providing the least compensation
for Motion and ‘High’ providing the most compensation.
Frame/bob The two fields are shown consecutively.
This menu item allows the user to specify whether the source has diagonal
interpolation applied to it when de-interlacing occurs. This reduces ‘jagged’
artifacts on moving images, however is not suitable for noisy sources where
the noise could be mis-interpreted as a diagonal or sloping element of the
picture.
This menu item allows the user to specify whether the source has noise
reduction applied to it. This is performed by averaging the video signal over a
number of fields – but ignoring areas where motion has occurred. If motion
blurring is seen, it is recommended to turn this setting off.
