Functions of the Grablink Quickpack CFA include a Bayer pattern decoder and a luminance blender providing simultaneous Y and RGB output -planar or packed- for monochrome and colour inspection.
The Grablink Quickpack CFA (colour filter array) is a flexible and high-performance image acquisition and pre-processing board dedicated to area-scan colour inspection.
A set of dedicated on-board pre-processing functions speed 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 colour inspection.
An optional white balance is computed on automatically selected white pixels or on 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 85MHz and it processes 8, 10 or 12-bit images.
The board has a 128Mbyte memory and a 64-bit, 66MHz Conventional PCI bus offering 240Mbit/s of delivery bandwidth.
Quickpack CFA features nine general-purpose I/O lines to ease the board integration into industrial systems.
