8 Recording with Fas M otion
8-1 Setting Frame Rate and Resolution
Record Settings are interactive:
• The Resolution y ou choose will define the m a ximum
Frame Rate and number of frames that can be captured.
• The Frame Rate will define m a ximum Shu tt er Speed
(exposure time in
m
sec).
• The Frame Rate and number of Frames captured defines
the duration of the r ecording (time in se c onds).
• If you select Autoset in either Frame Rate or Resolution,
that parameter will be selected automati c ally to its
maximum allowable value, dependant on the other
current settin
To set the Resolution of the TS3:
1. Select the Aspect Ratio y ou wi s h 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 c an be refined t o 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. O
ft en the best way to do this is
by dragging it with the mouse until it is close o the value
you want, then using the arrow keys to “zero in” on the
exact value.
To set the Frame Rate of the TS3:
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, t o make use of the best resolving
properties of y our lens, you will want to center the image
at the opti c al 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
y our ROI (Region of Interest) without moving the camera.
Lets say, for example, that you have captured images at 1024 x 1024 @ 500fps and are now interested at
capturing a 512 x 512 portion of the scene, l
e ts say the bo tt om right hand quarter @ 2000fps.
In this case, you would wish to add 512 to both the X and Y o ff set. For a 1024 x 1024 centered image
the o ff sets will be 128 and 0. The resultant o ff sets for a 512 x 512 image (lower right quadrant)
would be 740 and 512.
