CVI File Details
Legacy files using the “.CVI” extension contain all operating parameters related to the frame
grabber board - what the frame grabber can actually do with camera controls or incoming video.
The Sapera parameter groups within the file are:
•
Activate and set any supported camera control mode or control variable.
•
Define the integration mode and duration.
•
Define the strobe output control.
•
Allocate the frame grabber transfer ROI, the host video buffer size and buffer type
(RGB888, RGB101010, MONO8, and MONO16).
•
Configuration of line/frame trigger parameters such as source (internal via the frame
grabber /external via some outside event), electrical format (TTL, RS-422, OPTO-isolated),
and signal active edge or level characterization.
Saving a Camera File
Use CamExpert to save a camera file (*.ccf ) usable with any Sapera demo program or user
application. An example would be a camera file, which sets up parameters for a free running
camera (i.e. internal trigger) with exposure settings for a good image with common lighting
conditions.
When CamExpert is setup as required, click on File•Save As to save the new .ccf file. The dialog
that opens allows adding details such as camera information, mode of operation, and a file name
for the .ccf file.
Camera Interfacing Check List
Before interfacing a camera from scratch with CamExpert:
•
Confirm that Teledyne DALSA has not already published an application note with camera
•
Confirm that the correct version or board revision of Xtium-CLHS PX8 is used. Confirm that
the required firmware is loaded into the Xtium-CLHS PX8.
•
Confirm that Sapera does not already have a .cca file for your camera installed on your hard
disk. If there is a .cca file supplied with Sapera, then use CamExpert to generate the .ccf file
with default parameter values matching the frame grabber capabilities.
•
Check if the Sapera installation has a similar type of camera file. A similar .cca file can be
loaded into CamExpert and modified to match timing and operating parameters for your
camera, and lastly save them as Camera Configuration file (.ccf).
•
Finally, if there is no file for your camera, run CamExpert after installing Sapera and the
acquisition board driver, select the board acquisition server, and manually enter the camera
parameters.
