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 msec).
• 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
5.2.1 To set the Resolution of the Camera:
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 48 x 32 to 1280 x 1024 on
Blaster’s Ranger II™ Lt
; 48 x 32 to 800x 600.
Minimum resolution in Long Recording Mode is 320 x 240.
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.
5.2.2 To set the Frame Rate of the Camera:
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.
5.2.3 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, let’s 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.
5.3 Setting Shutter Speed
The Shutter Speed is expressed in microseconds of exposure time.
Minimum Exposure:
Minimum exposure is 2msec (regardless of frame rate)
