CCD Dynamic Range Extension V2: Double Exposure

EDIT: Uhmm... not so pretty as I thought initially, so no need to bother, I removed it.

Could only work for static images. Fast moving images would cause artifacts.

You are right, objects that has been moved relative to the frame during the first exposure, would be trickier to combine, shame I didn't notice!

But it could be used with higher shutter speeds, so the objects appear almost still and not blurred, along with a motion compensated algorithm. Or simply the moved objects could be excluded from the enhancement during the process. At least, it could be usefull for slow moving or static scenes, since almost no added hardware is required.

After a second thought I removed it, because I wouldn't post it if I had noticed this problem at first place. It requires too many tricks to work, so probably it doesn't worth the effort...
