Single megapixel Camera

We all are used to multimillion mega pixel cameras but I found a recent research on developing a single mega pixel camera!! .Yes you read that right a single mega pixel. The new approach aims to deal with one of the basic dilemmas of digital imaging that is the gigantic waste factor. When you capture a picture on a mega pixel camera it stores a million numbers (the light levels from the pixels). No camera can store that much information for hundreds of pictures, so an immediate data compression takes place right there inside the camera. A tiny microprocessor performs a Fourier transform; that is, it converts the digital image into a weighted sum of many sinusoid waves. Instead of a million numbers, the representation of the image can now been compressed into something like 10,000 numbers, corresponding to the most important coefficients from the mathematical transformation. These are the numbers actually retained for later processing into pictures.
