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 CCF file usable with any Sapera demo program or user application. An
example would be a camera file that sets up parameters for a free running camera (i.e. internal
trigger) with exposure settings for a good image with common lighting conditions.
To save parameters in a CCF file
1.
On the File menu, select Save Configuration As.
2.
Add details such as camera information, mode of operation.
3.
Change or enter a file name.
4.
(Optional). The default folder for user-generated .ccf files is
Teledyne DALSA\Sapera\CamFiles\User. You may choose another folder by selecting Select
Custom Directory, then choosing Browse.
5.
Click Save.
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 files [
•
Confirm that the correct version or board revision of Xtium2-CXP PX8 is used.
•
Confirm that the required firmware is loaded into the Xtium2-CXP PX8.
•
Confirm that Sapera does not already have a .cca file for your camera. 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; the parameters can then be saves as a .ccf file.
•
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.
