Tookis writes "Most of us are happy to take 2D happy snaps with single lens digital cameras. Imagine if you had a digital camera that could more accurately perceive the distance of all objects in its field of vision than your own eyes and brain. That's exactly what a team of researchers from Stanford University are working on — and it could even be affordable for ordinary consumers."

First of all they are ladened with pretty nasty Digital Rights Management. If you try to access one with your digits and you don't have the proper authorization, you're going to get whacked. And it's harder than you'd think to get authorization. The one I tried seemed to have been encumbered with the ForePlay(tm) DRM system. Man, you practically have to jump through hoops to get any access at all.
Also, you'd think that you pay once and it's yours forever, right? That's not how it works. It's kind of a pay-per-use situation. You've got to buy dinner, movie, etc. Then once you've spent all the cash, you have to negotiate the whole ForePlay system and then finally you get access -- maybe. These things seem to be pretty flakey, because most of the time I just got the "headache" response. What's worse is that the more time that goes by, you have to spend progressively more money. And even with that expenditure, somehow you end up will less and less access.
Oh and did I mention that you're only supposed to have one at a time? That's right. Let's say your primary girl is in headache mode, you aren't supposed to be able to get access to another girl. You just have to wait until the first one comes back on line. *And* most of them are equipped with spyware that calls you up every couple of hours and says inane things like, "Whatcha doin'?"
So, like I said, they're OK I guess. But probably they won't be that popular with most

You might think yours is GPL'd right now, but I think you are going to find that later, when you start thinking about distributing copies, that EULA is going to come up and bite you on the arse. At some point, they ALL have a clause about using other systems.
Me, I think I'm pretty lucky. Mine is expensive, but she brings me cans of beer and watches the football with me, while the dinner is being cooked and the washing machine is doing its things. I've hacked the access system so ForePlay is minimal, but on

Closely related recent development from Adobe? (Score:4, Informative)
It looks like here we've got an image sensor that would allow you to use your own lens, again provided that whatever camera body it found its way into had the right adapter. They also mention that it doesn't necessarily need an objective lens, though, and that's interesting...
Re: (Score:2)
Not correcting you or anything, but I believe, Adobe's innovation comes from using the Photoshop application along with the compound lens. So it's not only the adapter which will be required, but with the new Photoshop application so that compound image can be rendered as 3D.
But the primary difference I believe is that, 19 objective lens taking one single image compounded in 19 s

If you have a monochrome CCD image sensor and have interchangable filters, then you can keep your images to the full resolution of the sensor, and have a much easier time sharpening the image.

They've shrunk the pixels on the sensor to 0.7 microns, several times smaller than pixels in standard digital cameras.

The first benefit of the Stanford technology is straightforward: Smaller pixels mean more pixels can be crowded onto the chip.
I thought the prevailing wisdom was that smaller pixels equaled noiser images, assuming the sensor size stayed the same. Did I miss something in TFA which explains how really small pixels somehow change this dynamic?

Also, I'm not quite sure I'm understanding this right, but would this mean the camera is NEVER out of focus? Like, you'll be able to make out every detail of my thumbprint on the corner of the lens and also see the face of the person I'm photographing and ALSO read the inscription on the wall half a mile behind them?
Man, this thing sounds really cool.

They've made some progress on the manufacturing front. Last time I saw this idea posted to /. they were talking about placing a sheet of small lenses in front of a standard camera CCD at the focal point of the main camera lens.
From what I understood the last time, each small lens intercepts all the light at that focal point and splits it up on the small pixel grid behind it. So instead of just getting the intensity of the light at that point you also capture vector information about where that light entere

Existing 3D technology (Score:4, Informative)
Stereographic imagery has existed since before the creation of the camera. 3D cameras have undergone several bouts of popularity. As a child, I remember my grandfather getting out his ancient 3D camera, and my father had a 3D adapter for his regular camera. 3D lenses are now available for digital SLRs [loreo.com], and if you are interested in video, you can even get a box that converts 2D TV to 3D TV in realtime [yahoo.net]. (Note: CRT TV required. That aside, I've got one, and it works much better than I expected.)
Among the advantages of the system they're describing in the article we're discussing is that it actually has depth information for everything in the image, and using that, it can either be used for measurements or to pick out things in the image at specific depths. It also can be done with one lens, so the 3D image can be rotated while preserving the 3D effect. With conventional stereo imagery, you have to use 2 lenses, and if you turn the camera sideways to take the picture, you can only ever look at it sideways afterward.
In all, I think this new system sound like a great advance and I hope they'll license it cheaply so it can become widely used.

I would assume the term is used in the same sense that Super 8mm was used to denote a higher-quality image than that typically provided by Standard 8 mm on similar technology. The difference came from film/image management rather than objective lens improvement. I won't bore you with the details, but if you RTFA, you'll notice that the analogy applies quite nicely.
Your simplistic analysis and comment leads me to believe that you misunderstood the reference.
