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, that is, 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 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 (CORECO Camera Configuration file) 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 later) and the
CamExpert utility.
CCA File Details
DALSA distributes camera files using the ".CCA" extension (CORECO CAMERA files) that contains
all parameters describing the camera video signal characteristics and operation modes (that is, what the
camera outputs). The Sapera parameter groups located within the file are:
•
Video format and pixel definitions.
•
Video resolution (pixel rate, pixels per line, and lines per frame).
•
Synchronization source and timings.
•
Channels/Taps configuration.
•
Supported camera modes and related parameters.
•
I/O hardware signal assignment.
CVI File Details
Legacy files using the ".CVI" extension (CORECO VIDEO files) contain all operating parameters
related to the frame grabber board, that is, what the frame grabber can actually do with camera
controls or incoming video. The Sapera parameter groups located within the file:
•
Activates and sets any supported camera control mode or control variable.
•
Defines the integration mode and duration.
•
Defines the strobe output control.
•
Allocates the frame grabber transfer ROI, the host video buffer size and buffer type
(RGB888, RGB101010, MONO8, MONO16).
