What Makes Industrial Camera Colors Compromised?

In industrial quality control, monochrome cameras remain the standard. However, color cameras with higher resolutions are increasingly being adopted. The challenge lies in their limited color reproduction. This limitation is due to hardware constraints on sensors—specifically Bayer filters—which cannot perfectly capture all wavelengths of light simultaneously. These filters aim for ideal RGB channels but must compromise edge steepness and absorption levels across the spectrum.

The White Balance Limitation

The simplest approach to achieving balanced colors involves matching the gains of red, green, and blue (RGB) channels so that a neutral gray or white point reflects all three colors equally. However, Bayer filters inherently have spectral side densities—leakage into other color channels—which go unaccounted for in standard RGB gain adjustments. This shortcoming is the primary reason why industrial camera color reproduction falls short.

How FXO Series Solves It

The FXO series from SVS-Vistek implements a groundbreaking solution: Color Transformation Control Feature (CTCF). Instead of relying on basic RGB matching, CTCF applies real-time matrix operations to each pixel via an FPGA chip. This method incorporates the spectral side densities into calculations, ensuring significantly improved color accuracy without hardware changes.

The flexibility of this approach allows users to define custom matrices or choose from predefined ones—like D50 and D65—that cater to typical lighting scenarios (daylight at 5000K and 6500K).

FXO Series: More Than Just Color Correction

As the current benchmark in C-mount cameras, the FXO series combines advanced sensor technology with high-performance interfaces like CoaXPress-12. The Color Transformation Control Feature is just one of several innovations that deliver exceptional image quality and speed.
