Check this out! it's still in the early stages, but this looks to me like it could be a big thing.

Imagine a camera that's good for 25,000 shots per charge!
(I multipled the d50's rate to half of the expected 50 fold gain in efficiency)

The way I read it, that factor of 50 is just from the per-pixel A-to-D, then on top of that there's something like a factor of 100 reduction from the way they do the jpeg compression in hardware! You could run a multi-megapixel camera on a watch battery with this sensor, in fact camera-watches might become as common as cell-phone cameras are today.
And then there's that 1:100,000 dynamic range...
Of course this is still only in the lab, there may a catch somewhere (like in the noise level). |

I wish I could find the story about the camera on the Nasa Mars Rover. the camera was only a 1.3 MP camera, and gave excelent results.
what they did was reduce the number of pixels on the sensor, but increased their quality and color depth or something. so more pixels in a small sensor is not the best answer. Im sure this camera cost a ton of money to develope and produce

| James, here's a detailed description of the PanCam on the NASA rovers currently on Mars. The "Technical Briefing" at the bottom of the page has the full specs. A marvellous device indeed, but not exactly the ideal camera for a walk around town (f20, no zoom, no focus). I got to work with images from its lowly brother, the NavCam, which is the 640x480 gray-scale stereo camera dedicated to obstacle detection. |

watch it be noiseless or something. lol |

I wouldn't expect noise to be an issue with that dynamic range. They have a lot of headroom to work with. Actually the dynamic range is more exiting to me than battery life or small size.
