CamExpert Quick Start X64 Xcelera-CL PX4 User's Manual
The total size of the two internal frame buffers must be somewhat smaller than the total onboard memory
due to memory overhead required for image transfer management. Also note that the X64 Xcelera-CL
PX4
board when configured for two Base inputs, equally divides the onboard memory between the two
acquisition modules, reducing the available memory for the two buffers by half.
Overview of Sapera Acquisition Parameter Files (*.ccf or
*.cca/*.cvi)
Concepts and Differences between the Parameter Files
There are two components to the legacy Sapera acquisition parameter file set: CCA files (also called cam-
files) and CVI files (also called VIC files, i.e. video input conditioning). The files store video-signal
parameters (CCA) and video conditioning parameters (CVI), which in turn simplifies programming the
frame-grabber acquisition hardware for the camera in use.
Sapera LT 5.0 introduces a new camera
configuration file ( CCF ) that combines the CCA and CVI files into one file.
Typically, a camera application will use a CCF file per camera operating mode (or one CCA file in
conjunction with several CVI files, where each CVI file defines a specific camera operating mode). An
application can also have multiple CCA/CCF files so as to support different image format modes
supported by the camera or sensor (such as image binning or variable ROI).
CCF File Details
Files using the “.CCF” extension, (Camera Configuration files), are essentially the camera (CCA) and
frame grabber (CVI) parameters grouped into one file for easier configuration file management. This is
the default Camera Configuration file used with Sapera LT 5.0 and the CamExpert utility.
CCA File Details
DALSA distributes camera files using the “.CCA” extension, (CAMERA files), which contain all
parameters describing the camera video signal characteristics and operation modes (what the camera
outputs). The Sapera parameter groups within the file are:
•
Video format and pixel definition.
•
Video resolution (pixel rate, pixels per line, lines per frame).
•
Synchronization source and timing.
•
Channels/Taps configuration.
•
Supported camera modes and related parameters.
•
External signal assignment.
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.
