Falcon™ 4-CLHS Series Operational Reference 25
Device Selector pane: View and select from any installed Sapera acquisition device if more
than one is installed in the computer. After a device is selected CamExpert will only present
parameters applicable to that device.
Parameters pane: Allows viewing or changing all acquisition parameters supported by the
acquisition device or frame grabber. This avoids confusion by eliminating parameter choices
when they do not apply to the hardware in use.
When using a Teledyne DALSA frame grabber and camera, CamExpert groups all frame grabber
parameters under the Board heading, and the supported camera features under the Attached
Camera heading.
Display pane: Provides a live or single frame acquisition display. Frame buffer parameters are
shown in an information bar above the image window.
Control Buttons: The Display pane includes CamExpert control buttons. These are:
Acquisition control button:
Click once to start the frame grabber live grab mode, click again to stop.
The Falcon4 is always in free running acquisition mode unless configured to
use an external trigger.
Single frame grab:
Click to acquire one frame from the frame grabber device.
Software trigger button:
With the I/O control parameters set to Trigger Enabled / Software Trigger
type, click to send a single software trigger command.
CamExpert display controls:
(these do not modify the frame buffer data)
Stretch (or shrink) image to fit, set image display to original size, or zoom
the image to any size and ratio. Note that under certain combinations of
image resolution, acquisition frame rate, and host computer speed, the
CamExpert screen display may not update completely due to the host CPU
running at near 100%. This does not affect the acquisition.
Histogram / Profile tool:
Select to view a histogram or line/column profile during live acquisition.
Output Messages pane: Displays messages from CamExpert, camera or the interface driver.
Link Signals: Displays the status of various Link.
CamExpert View Parameters Option
While the Board section shows all frame grabber parameters, the Attached Camera section
shows camera features filtered by a Visibility attribute that selects the targeted user. These vary
from Beginner (features required for basic operation of the device) to Guru (optional features
required only for complex operations).
Choose parameter visibility via the [ << Less More>> ] control below each feature list. You can
also choose the visibility level from the View > Parameters Options > Visibility options menu.
