While this prototype of the single pixel camera takes 5 minutes to shoot a still image, it is still capable of taking high-resolution pictures. Well, researchers at the Rice University have created a prototype of a camera that develop an image by taking just one pixel a number of times in a swift succession. And the quality is equal to that of the one-megapixel image. The researchers used some new mathematics and a silicon chip covered with hundreds of thousands of mirrors. It integrates a single photodiode that transforms light into electrical signals instead of a million of photodiodes as used by usual digital cameras. In the single-pixel camera, the image is shined onto the DMB and from there is bounced through a second lens that focuses the light on the single photodiode. At the same time, the DMD mirrors shuffle and every shift enables the photodiode to record a new pixel value. The only drawback with the prototype is that it is able to shoot still pictures only. So, I don’t think it would have any significant effect on the digicam market
