● Video Standard Mode
Select between NTSC and PAL video standards.
● Colour Settings Mode
Change the Brightness, Contrast, Hue, Saturation and Sharpness
of the video.
● Delay Settings Mode
Change the vertical and horizontal capture delay of the video. These
settings affect the vertical and horizontal position of the displayed image,
allowing the black borders to be equalised on either side and top and
bottom of the image (this adjustment may be necessary because
some analogue video signals do not conform exactly to the blanking
timing of the video standard and consequently a black stripe may be
visible on one side of the image).
NOTE : set Border in-fill to 'none' when adjusting the Delay Settings
so the effects of the horizontal and vertical delays can be clearly seen.
●OSD Mode
When this option is enabled, a message will appear on the screen whenever
stabilisation is disabled. It is not intended that On-Screen Annotation is
permanently enabled. Generally, it should be used to help set up the
Stabiliser in the following configuration situations:
→To see the effect of the Auto Disable pan/tilt and Auto Disable
Low Detail functions.
→To see if the stabilisation is being disabled because the camera
motion is too fast.
●MAX HORZ SHIFT / MAX VERT SHIFT
This is the maximum amount, in image pixels, that the algorithm shifts
the frame horizontally and vertically in either direction from the normall
position. Both horizontal and vertical shifts are settable in the range
[24 . 256], the default is 128.
Usually the only reason to select low Frame Shift values is when the
Border In-Fill is in Fixed mode because, as the borders are increased
in size, the viewable image area gets smaller by the same amount.
Warning : Setting these values too low will prevent the algorithm from
stabilising properly. The lower the setting the less stabilisation range
is possible.
ㆍLow Detail : When this option is enabled, the algorithm is disabled
when a scene with insufficient detail for reliable stabilisation is
detected. This prevents the image position 'hunting' when there
is very little scene detail or features. For example, when the camera
is pointed at a completely blank wall the stabilised image will jump
around slightly because it is locking on to the random video noise.
Similar hunting problems can occur in other situations where a
large part of the scene lacks suitable detail for Stabiliser lock:
→Other low contrast situations, such as at night scenes.
→Scenes with an absence of detail in one direction, such as
venetian blinds.
→Scenes with a repeated pattern, such as a brick wall.
Note : enabling the Low Detail mode can result in the stabilisation
being disabled prematurely on low contrast or noisy video, which
is why this mode is not enabled by default.
Restoring the factory default settings is done by first removing the power
and then restoring power while holding down the reset button on the front
of the unit. The reset must be held down for at least 10 seconds after
power has been restored.
This program represents the version.
