Kodak develops new sensor filter.

i'm guessing these new cells are used for luminance data? and if so, does this fix chroma noise? i wonder how much kodak will want for the rights? could be awesome for b&w digital.
 
Interesting...

Part of me wonders though if this will end up like the Foveon X3 sensor though. I remember when the X3 came out it was a huge deal, and then it just kind of faded away. Sad really, because it's an excellent sensor even with the relative lack of development.

Hopefully this isn't hype. P&S with a very clean ISO 1600 and maybe 3200 and DSLRs with a clean ISO 12800 would be nice. However, the brief explanation seems similar to what Fuji already has done. I guess we'll have to wait and see.

Ya, it's too bad the Foveon guys suck at marketing to big companies. From what I know, they really botched it up peddling it to the big names.
Maybe Kodak will be better at pitching this.
Or maybe they can re-enter the SLR field, create their own body and use the EOS mount.
Wishful thinking, because their previous bodies were horrible.
And yet, Fuji is doing just fine with the S3 and S5.

Yes but when it came down to it, at the resolution being offered by Foveon, the performance left a lot to be desired, especially with regard to low light performance, the supposed bread and butter of the DSLR. My understanding is that the required stacking of the color cells on the sensor led to decreased sensitivity. That in conjunction with lower resolution and lower quality body's was the issue.

it was their own fault it hasent been developed, they were too closed about it


on the topic tho 10$ says Nikon ends up with the first one of these

Those are the rumors anyway. Then again the specs of the D3 according to rumors are so amazing that they rival Herculean myths.

Way to thread-crap.

It would be nice to see better, cleaner higher ISOs on P&S cameras. ISO 400 on my Canon S400 (from around 2003/4) looks like crap.
 
When was the Foveon introduced? If I remember right, they signed a two year exclusive deal with Sigma.
 
Here's my take on this technology.

First, the technology is very simple. It simply makes the camera act more like the human eye and less like a simple grid. Instead of filtering everything into RGB, this technology filters things into RGBL where L is basically just a clear filter. Now luminance data is provided which is combined with the other data to arrive at your final pixel. Since the clear filter is 200% brighter than a colored filter, more energy is collected and more energy is like a bigger sampling size and due to the law of averages, that produces less signal noise.

But's that approach is not without it's problems.

The signal would only be more accurate in the Luminance domain. It would be less accurate in the color domain. So you're trading color accuracy for luminance accuracy. In low light situations, this is a worthwhile trade.

Also, since you would have to spend die area on clear subpixels, you would lose resolution.

The problem with press releases like this is that they only tell you the positives but none of the negatives.

Foveon's X3 technology is ultimately superior but fabricating a 3d cell structure is hard on semiconductor processes that were made for 2d structures. This Kodak technology is at least easy to implement (although that's only because it is not really a technological advance at all).

It wouldn't do anything for black and white cameras because B&W cameras already do the thing that this tech does. In a way, this tech creates a hybrid B&W&Color camera.

 
I don't care too much about low light performance. The dynamic range of these sensors are still far from what the human eye sees. At least now you can get a clean picture with a sensitivity that surpasses the eye.

<--feels retarded because he forgot the SLRs
