Hi Toengel,
I don’t know the answer to your question, though I could ask. I’ll tell you a bit about the history behind ISF calibration. In 1997 we were making LCD projectors and the first plasma TVs. We were getting feedback from the USA that our projectors were being tested with the “Video Essentials” DVD from Joe Kane, and that the calibration was not so good. Joe was one of the 2 founders of the Imaging Science Foundation (ISF). He later left the ISF to his partner and started JKP for making more DVDs, like “Digital Video Essentials”, also in HD (on Blu-ray).
We invited Joe Kane to come to Eindhoven, and he tought us a lesson about calibration, using his DVD for the test images. Initially it was mostly about setting the correct black and white levels, avoiding clipping, and setting the saturation gain to exactly 1. Then you check the grey scale.
It was an inspiration for me to later design some circuits for color space conversion (when wide color gamut was introduced) and gamma correction.
After 25 years and 2 months with Philips TV I was transferred to TP Vision, and 1 year and 9 months later I was laid off. My last project was all about calibration and image enhancement. I am now working in Philips Research on a TV related topic, but not intended for TP Vision.
