Grablink Quickpack
CFA : Image acquisition and pre-processing for color area-scan
inspection
The Grablink Quickpack CFA -Color
Filter Array- is a flexible and highperformance
image acquisition and pre-processing board dedicated
to area-scan color inspection. A set of dedicated
on-board preprocessing functions speeds up image
processing for applications such as PCB, food or
pharmaceutical inspection without loading the host
CPU.
These functions include a Bayer pattern decoder
and a luminance blender providing simultaneous Y
and RGB output ?lanar or packedfor monochrome and
color inspection. An optional white balance is computed
from automatically selected white pixels or from
a userdefined Region Of Interest. Finally, four
independent LUT operators are available for the
R, G, B and Y components.
The Grablink Quickpack CFA interfaces Base configuration
Camera Link area-scan cameras up to 85 MHz and it
processes 8-, 10- or 12-bit images. The board has
a 128 MB memory and a 64-bit, 66 MHz Conventional
PCI bus offering up to 240 MB/s of delivery bandwidth.
The Grablink Quickpack CFA features nine general-purpose
I/O lines to ease the board integration into industrial
systems.
Flexiblility
Fully programmable pre-processing on 8-, 10-,
12-bit input images
Y and RGB, planar or packed output formats
High-performance
Image pre-processing without loading the host
CPU
Shorter acquisition and processing time
On-board
image pre-processing
All operators are compatible with 8-, 10- and 12-bit
input images
Bayer Pattern decoder:
Compute the RGB components of the image
White balance operator:
The white balance parameters can be specified by the
user or computed automatically from the image.
They can be computed continuously (on each image)
or once only (under user control). Moreover, they
can be computed from automatically selected white
pixels in the image, or from a user-specified region
of interest.
Luminance blender:
Compute the Y component of the image
Four LUT operators, on R, G, B and Y channels
