Egami spotted a new Olympus RGBCMY multilayer sensor. A sort of advanced version of the Sigma Foveon tech. The goal is to deliver a High Sensitivity and High Color Fidelity. Don’t know if we will ever see such a sensor on a digital camera tough.

I’m not sure what the gain is.
Thing about the Foveon sensor is that it gets what basically gets translated into luminosity information at every site without filtration. The color discrimination obtained in the lower layers are what becomes problematic and generate noise in low light.
This Olympus approach abandons no filtration AND luminosity information at every site. It probably uses CYM filtering to keep the light loss low, but the CYM and sometimes G model has color issues of its own, which is why Nikon abandoned it a long time ago.
So, short of seeing their demosaic and sample data to do numeric calculations on, I’m not seeing what the gain is.
What a wonderfully elaborate explanation you don’t understand this patent.
No wonder – lousy sketch and a few lines of Google translated text. I don’t understand it either (Who am I anyway). But I can admit that in two simple words…
CMY filtering has at times been popular in the amateur astrophotography community. It has some advantages, and some disadvantages. I suspect that this patent exists mostly to stake out territory. I wouldn’t expect to see it implemented any time soon.
That’s why you’re a marketeer and not engineer
I suppose. But I’ve yet to see an engineer explain what the gain would be. Indeed, even the original patent doesn’t seem to talk about gain, it talks about difference.
What a reasonable reply to a snarky drive-by comment. The internet will collapse if this spreads.
just another patent.
Seems like a good idea except that Olympus aren’t actually in the making of sensors business. They make medical endoscopes and a few cameras; they buy sensors from the electronics companies.
Still looks like a tiny sensor.
It’s a matter of perspective. Is it the sensor that’s tiny, or your mind?
