SpectraCal introduces DLC technology

SpectraCal, a company dedicated to the development of calibration software, has announced its new technological breakthrough in the process used to correct the color performance of professional monitors.

It is the addition of new algorithms, called Dynamic Linearity Correction (DLC), to its CalMAN Studio product, allowing the widespread adoption of 3D LUTs to perform this correction.

This new technology arises from a fundamental problem that many of the company’s users had: the time it took for the monitors to generate a specific profile was about 4 hours, which in many cases was too long because the monitor could not be used to continue working in the meantime. Now, SpectraCal claims that DLC allows accurate profiles to be created in less than an hour.

By using 3D LUTs, and not relying solely on integrated controls, a much more accurate result is achieved to meet industry standards.

DLC converts the work previously done by hand into an automatic process performed by the software. It works by determining the performance of the display by detecting areas of non-linear behavior and inserting more calibration points in them.

SpectraCal says it is a 17 x 17 x 17 x 17 grid, but as many measurements can be taken at trouble spots as would be done in a manual process. Thus, the resulting LUT is better but does not take longer to produce.

CalMAN Studio 5.3.5 is the first release to include DLC technology, although it is currently in beta. SpectraCal has also released a White Paper detailing the theory and methodology of Dynamic Linearity Correction.

Don’t forget that the next Digital Video Color Management and Calibration Course starts on July 10.
