Accident Could Lead To Better Digital Cameras 120
Dave Bullock (eecue) writes "Scientists at UCLA have accidentally created a material that will some day give us better, faster, cheaper, more flexible digital cameras. I toured their lab and shot a photo essay for Wired. Personally I'm looking forward to a quantum-dot embedded camera sensor someday soon. 'Graduate student Hsiang-Yu Chen was working on a new formula for solar cells when something went wrong. Instead of creating electricity when hit with light, the conductivity of the material she was working with changed. "The original purpose [was] to make a solar cell more efficient," says Chen. "However, during the research we found the solar cell phenomenon [had] disappeared." Instead, the test material showed high gain photoconductivity, indicating potential use as a photo sensor.'"

Ahhh. Well, if he wants to pay for it, it's technically feasible. Thing is, sensors are very expensive, the most expensive part of the camera. Add to that additional expense of the prism filtering, and there you have it. The 3CCD's are on video cameras because they're much lower resolution, cheaper sensors.
Go ahead and bitch, but 3CCD's are here. Just because they cost a lot doesn't mean that the tech isn't here. Hell... this development could even make 3CCD cameras more affordable to make.

The DP1 is NOT by any means a 3CCD camera. It uses a single special sensor that can resolve each color at each photo site (but with some limitations, a lot of postprocessing needs to be done).
3CCD cameras use a set of dichroic prisms to split colors and three separate CCD sensors, one for each colors. It's a completely different approach than the Foveon X3 sensor design, and so far one that has only been used in video cameras and not stills, probably because video cameras typically have lower resolution a

Re: (Score:2)
The Foveon x3 is the only one that makes sense in a consumer digital camera. CCDs are just too expensive and a 3CCD with the prism plus alignment issues would make it even worse so it's kind of unrealistic to expect it in a consumer digital camera.

The biggest problem with most digital cameras at this point is that they have tiny, low quality lenses pointed at tiny little sensors. The next problem is that the operator is incompetent (I take horrible pictures).
Instead of over-sized 5 megabyte, poorly framed, poorly lit snapshots that are the norm today, we are going to have super-sized 25 megabyte, poorly framed, poorly lit snapshots.
Hopefully the increase in speed is decent.

I suspect with faster cpu's, and denser cheaper faster storage, and so much more data processing. Some of those issues just may be solved in software, and some seemingly minor discovery like this one may be the key.
IE in a few years the camera may be able to model every defect in crappy lenses simply by pointing it towards any reference landmark that a near perfect reference photo exists. Since software already exists to make bracketed photos, etc a fast enough camera that can vary enough parameters on it

that's just poor framing, not a fatal flaw of HD cameras. With enough 60"+ TV's out their, instead of zooming in on one small portion, I say add more "actors" (or mirrors) and less extreme zooms, since we can now get that same detail without a zoom.
Granted if they take the same clips, etc, and just filmed in HD that would be worse. Changing how they film to match the media will eventually make it all much better.

Not true at all. Sharpness of a given lens may be diffraction limited at a given aperture, but that doesn't mean better sensors are worthless! Light sensitivity and dynamic range are the true limiting factors for digital imaging. Any technology that increases either will move digital closer to film, which has been the goal all along.
Not only that but the article mentions the substance being flexible. If the technology is good enough it could be able to curve the sensor in the way that best overcomes the limitations of your cheap lens.
