Sensor Design and Video Codec Design

The “Open Isn’t Enough” conference (= “No Time to Wait 5”) was scheduled at Nederlands Instituut voor Beeld en Geluid in Hilversum, Netherlands, on 8–10 December 2021. Because of the pandemic, the conference was transitioned into an online one.


This presentation delves into a few aspects of the physics and mathematics of colour filter mosaic and raw data, which do have a huge importance in sensor design and – in the presenter’s opinion – should be considered in video codec design as well.

Having graduated in both mathematics and computer science, Reto Kromer became involved in audio-visual conservation and restoration thirty-five years ago. He has been running his own preservation company, AV Preservation by, and lecturing at the Bern University of Applied Sciences and the Elías Querejeta Zine Eskola in Donostia (San Sebastián). His current research includes colour spaces, look-up tables and codec programming and emulation. Previously he was head of preservation at the Cinémathèque suisse (the Swiss National Film Archive) as well as a lecturer at the University of Lausanne and the Academy of Fine Arts Vienna. He served as an AMIA board member during four years. His work has seen him honoured with an inaugural JTS Award.
