The japanese blog Egami (Click here to read the quirky google translation) found a new Panasonic patent that displays a sort of foveon sensor. The google translation is not so good but as far as I understood that sensor has no Low Pass filter. There is a sort of “photonic crystal” that splits the light into RGB directing the single beams to three different micro sensors. Unlike the Sigma foveon which has three layers placed one under the other the new Panasonic sensor would avoid the light loss typical from foveon sensors (that’s why foveon sucks at high ISO). As usual with patents this sounds very promising. But it is a patent so there is no clue if we will ever see such a sensor in a real camera!
The next patent found by Egami (via Nexthardware) discloses a patented from Olympus that allows a flash sync speed of 1/20.000 of a second! The even more interesting news is that the technology is based on a new electronic shutter system!
