- Is exact color measurement or analysis the core of your machine vision requirements?

- Does the demosaicing process of single-chip Bayer color filter arrays cause unacceptable visual artefacts?

- Are you looking for 2D imaging techniques producing absolute color accuracy?

We offer 2 Techniques capturing red, green, and blue light simultaneously at each pixel location.

The Foveon technology takes a very different approach to sensor design than any other company out there. A 3-layer CMOS technology captures red, green, and blue light simultaneously at all pixel locations across the entire sensor surface.

The other technique, using prism based 3-CCD imaging technology, is provided by our Condor³ RGB range. A specific R, G, and B value is captured for each pixel. In contrast with Bayer color cameras using interpolation routines, 3-CCD results in more accurate per-pixel color values. In addition, because there is no interpolation, 3-CCD images offer more precise spatial resolution, enabling more accurate edge detection..

On the High-end of our color measurement solution spectrum we offer our Condor³ CIE 3- channel Beam Split Prism camera with X-Y-Z filtering. As there are different color spaces, the most desirable of these in the measuring of color is the L*a*b* color space due to the uniform distribution of colors, and because it is very close to human perception of color.

“Lab” is now more often used as an informal abbreviation for the L-a-b representation of what is often referred to as the CIE 1931 color space.

When exact color measurements on every pixel are the core of your machine vision requirements, our 3 Layer CMOS or 3 CCD cameras are what you need.

Foveon made history when it developed and patented the world’s first three-layer image capture technology, placing a stack of RGB pixels in each pixel location. As a result, Foveon sensors detect all three primary colors in every pixel location, producing images that are sharper and have significantly reduced image artifacts compared to competing image sensor technologies.

Similar benefits are attained using our prism technology based 3-CCD cameras capturing specific R, G, and B values for each pixel without any interpolation.
