Canon Patents Hi-Res Images By Pixel Shift

The Japanese Photography Blog, Egami has uncovered another Canon patent. It apparently aims to create sharp photos by enhancing the pixels in multiple images taken during continuous shooting. One might say it acts as a complement to Image Stabilization technology. You can read the original article here in Japanese.
