Record Settings are interactive:
•
The Resolution you choose will define the maximum
Frame Rate and number of frames that can be
captured.
•
The Frame Rate will define maximum Shutter Speed
(exposure time in
m
sec).
•
The Frame Rate and number of Frames captured
defines the duration of the recording (time in
seconds).
•
If you select Autoset in either Frame Rate or
Resolution, that parameter will be selected
automatically to its maximum allowable value,
dependent on the other current settings
To set the
Resolution
of the IL3:
1. Select the Aspect Ratio you wish to use: choices are
Custom, 5:4, 4:3, and 16:9.
2. Adjust the image Width (in pixels) you wish to use.
This can be done either by editing the number in the
Width edit box, or by moving the slider.
Resolutions can be refined to any even-numbered pair
from 24 x 12 to 1280 x 1024.
Whenever any slider has focus, it turns blue. It may be
then controlled by dragging it with the mouse or using
the keyboard arrow keys. Often the best way to do this is
by dragging it with the mouse until it is close to the value
you want, then using the arrow keys to “zero in” on the
exact value.
To set the Frame Rate of the IL3:
Either edit the number in the Frame Rate edit box, or
move the Frame Rate slider to the desired position using
the mouse and arrow keys.
Offset Control:
Most of the time, to make use of the best resolving
properties of your lens, you will want to center the image
at the optical center, which corresponds to the center of
the sensor. In this case you would make sure that the “Center” check box is checked.
It is also possible, that you will wish to shift your ROI (Region of Interest) without moving the camera.
Let’s say, for example, that you have captured images at 1024 x 1024 @ 500fps and are now
interested in capturing a 512 x 512 portion of the scene, lets say the bottom right hand quarter @
2000fps.
In this case, you would wish to add 512 to both the X and Y offset. For a 1024 x 1024 centered image
the offsets will be 128 and 0. The resultant offsets for a 512 x 512 image (lower right quadrant) would
be 740 and 512.
