I've searched everywhere with no avail. Does anyone know if CMOS chips can suffer from "hot pixels" or "stuck pixels" like CCD's? If so, are there pixel masking techniques for them?

I don't know too much on the subject, but, yes, CMOS chips like CCDs can suffer from hot pixels and dead pixels for that matter. Some CMOS chips have a correction method in which the closest neighbor to the bad pixel in a way replaces it. I don't know the technique, but I've had heard of it.

I know in some digital still cameras they have what is called a DFS, dark-frame subtraction, which a dark frame is added to mask the hot pixels.

Thanks for the information!
