pixel value readout, image zoom, and line profiler.
Functional tools include hardware Flat Field calibration and operation support (see “ Using the Flat Field
Correction Tool ” on page 36 ), plus support for either hardware based or software Bayer filter camera
decoding with auto white balance calibration (see “ Using the Bayer Filter Tool ” on page 38 ).
Camera Types & Files Applicable to the X64
Xcelera-CL PX4
The X64 Xcelera-CL PX4 supports digital area scan or linescan cameras using the Camera Link interface
standard. See " Camera to Camera Link Connections " on page 20 for information on connecting a Camera
Link camera.
Contact DALSA or browse our web site [ http://www.imaging.com/camsearch ] for the latest information
and application notes on X64 Xcelera-CL PX4 supported cameras.
Camera Files Distributed with Sapera
The Sapera distribution CDROM includes camera files for a selection of X64 Xcelera-CL PX4 supported
cameras. Using the Sapera CamExpert program, you may use the camera files (CCA) provided to
generate a camera configuration file (CCF) that describes the desired camera and frame grabber
configuration..
DALSA continually updates a camera application library composed of application information and
prepared camera files. Along with the camera search utility on the DALSA web site, as described above,
a number of camera files are ready to download from the DALSA FTP site
[
ftp://ftp.coreco.com/public/Sapera/CamFile_Updates ]. Camera files are ASCII text and can be read with
Windows Notepad on any computer without having Sapera installed.
CamExpert Memory Errors when Loading Camera
Configuration Files
The memory error message [ Error: "CorXferConnect" <Xfer module> - No memory () ] may occur
when loading a Sapera camera file, or when the application configures a frame buffer for area scan
cameras. The problem is that the X64 Xcelera-CL PX4
does not have enough onboard memory for two
frame buffers.
The X64 Xcelera-CL PX4 when used with area scan cameras, allocates two internal frame buffers in
onboard memory, each equal in size to the acquisition frame buffer. This allocation is automatic at the
driver level. The X64 Xcelera-CL PX4
driver allocates two buffers to ensure that the acquired video
frame is complete and not corrupted in cases where the transfer to host system memory may be
interrupted by other host system processes.
