I think many DSLRs have something like this built in. You can "clean" the sensor through a menu option, and I believe the camera maps the sensor to find dead or hot pixels, and then interpolates around them.

I bet a simple program could be written to take a hot pixel file (1s exposure with the cap on) and use it to interpolate around the hot pixels, thus cleaning up the image. It would be easy to do with RAW, a little harder to do with JPEG.

Gads, my 6mp camera has 2 hot pixels. My 3.2 mp camera has 3. I can only imagine how many there would be on a medium format sensor.....
At the risk of sounding dumb, how does one spot a hot pixel on a DSLR?
They stick out like a sore thumb if they happen to fall in a dark area. The really bad one on my camera is bright purple, and very visible. On my G1, I had a bright red one, and I believe one was green. I know there is a third on it, but I don't recall what colour it is.
