Researchers Developing Single-Pixel Camera

Assassin bug writes "According to the BBC, researchers in the US are developing a single-pixel camera to capture high-quality images without the 'expense' of traditional digital photography. The idea behind such a device is that traditional digital photography is wasteful. Most of the information taken in by the camera is thrown away in the compression process. From the article: 'The digital micromirror device, as it is known, consists of a million or more tiny mirrors each the size of a bacterium. "From that mirror array, we then focus the light through a second lens on to one single photo-detector - a single pixel." As the light passes through the device, the millions of tiny mirrors are turned on and off at random in rapid succession. Complex mathematics then interprets the signals assembling a high resolution image from the thousands of sequential single-pixel snapshots. '"

Yes, it's a dupe.

From the FAQ:

Sometimes I see duplicate stories on Slashdot. What's up with that?

These are just mistakes on the part of the staff. They happen. We have posted over ten thousand stories in our history. The occasional duplicate is inevitable.

If you see a duplicate, you can mail the story's author. If the story is still quiet, we may pull it down. However, once the comments are rolling in, we often leave the story up so that the discussion can continue.

Some people have suggested that there might be a software solution to this problem. If you think you've got one, visit the Slashcode site and submit a diff. As long as it isn't a performance hit, I'd consider using it. (Be aware however that the trick of searching for duplicate URLs isn't as helpful as you might think, since the same story can appear in multiple locations.)

So if you really want to complain about it, consider contributing a Slashcode patch to fix it.

Re:RAW format anyone?

There is always a catch, however. Let's take an example of a 1MP camera, taking a picture at 1/100th of a second. Each CCD can acquire light for a full 1/100th of a second. But each one is small and as such, not very sensitive.

Let's say this new 1 pixel camera is set-up to take a picture of 1MP at 1/100th of a second. Each one of the 1M mirrors will reflect its light on the CCD for ... (1/100)/1000000 th of a second, because only one pixel (of the final image) can be recorded at a time. So yes, the new sensor will be more sensitive. And it better be ! 1 000 000 times to be correct (for 1MP pictures.)
