Non-linear sensor, but how? Since Aaron already told that there's no new sensor technology involved, only plain from-the-shelf technology...
As I stated in my previous mail, the only way to reduce noise is to increase exposure, but then the highlights are gone. Can the highlights be suppressed in some way? I know there are glasses that darken when exposed to light... Could it be feasible to integrate such material right in front of the sensor, so it darkens as more light hits the sensor, thus suppressing the highlights and keeping the shadows untouched. The material should be fast-responding, obviously! If this would work, a linear sensor would deliver a non-linear output, covering more dynamic range! I doubt that it will be logaritmic, as film densities are, but it seems like a nice try. Groeten, Vic PS. I'm going to subscribe for some patents :-). If some of you aren't already... But hey, I'll sue you and use the PDML archive to proove the idea is mine! >----- Oorspronkelijk bericht ----- >Van: Lie Arne [mailto:[EMAIL PROTECTED] >Verzonden: woensdag, augustus 16, 2006 04:14 PM >Aan: 'Pentax-Discuss Mail List' >Onderwerp: RE: Holy Crap -- Pentax 10MP body > >OK.
