Grablink Quickpack
CFA: Image acquisition and pre-processing for color area-scan
inspection
The Grablink Quickpack CFA -- Color Filter Array -- is a flexible and high-performance 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 -- planar or packed -- for monochrome and color inspection. An optional white balance is computed from automatically selected white pixels or from a user-defined 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.
Flexibility
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
