Wouldn't it be possible to get sharper black and white pics from a digital camera if you could somehow get the sensor data before the interpolation (to deal with the Bayer filter)? Instead of interpolating the data into colour and then turning the colour image into black and white, you'd just turn each pixel into a grey pixel (ie RBG of 255,0,0 for pure red would be turned into 255,255,255, as would 0,255,0 and 0,0,255 for pure green and blue respectively, assuming an 8 bit sensor). You would get a true 1 to 1 mapping of sensor pixel to output pixel.

Seems to me that it would require no more than a firmware update. It might also have the advantage of requiring less processing on the camera, so you could take pics more quickly. You could always do the processing later, either on the camera (so you could see the pics properly in the display) or on your PC, if you wanted a colour picture. I'm not sure if it would require more data to represent an image though, or less.

Does this make sense? Has it been done before?

Simple answer is no.

The Sigma SD14, and great for IR, was going to get one myself until the price shot back up
