The upscale modes will automatically set the best AOI and Aspect ratio to upscale
the image to the requested size. The upscale function used an advanced digital
zoom process. You should
NOT
use this function if you will make measurements
from the images.
6.3.4 Trigger
The Trigger Position is set using the Trigger Selection Combo. The Options available
are
START
,
CENTRE
,
END
and
CUSTOM
.
A
START
trigger allows a 5% pre-trigger.
An
END
trigger allows a 5% post-trigger.
For a
TRUE
START
or
END
trigger use the
CUSTOM
option. Select
CUSTOM
from the
Selection Combo OR Click the icon.
From this dialog you can select a precise trigger location, either as a percentage of
memory OR as a number of frames.
NOTE : For XLRT Operation of E64 Camera ONLY a Start Trigger is available.
This is a 0% start trigger rather than the standard 5% START Trigger described
above.
6.3.5 Low Light Mode
Where a lot of illumination is needed for the recording (usually HIGH FPS or Shutter)
, it is not always convenient to have the light available for setting up the recording
(focus, field of View etc). In these cases you can turn on LOW LIGHT MODE by
pressing this toggle button. With low light mode ON, the camera will operate at a
lower FPS and shutter for the purpose of setting up the shot. The Low Light Mode will
be automatically disabled when the camera is put into ARM mode.
The Effective FPS in LOW LIGHT MODE is specified in the camera preferences in
software Settings (see 6.16.1 ).
NOTE : If you choose a low light mode < 500fps, then the View Finder Image will
NOT be available.
