Northlight Images has uncovered an interesting patent that deals with reducing the need for an AA filter.
This patent shows a technique to use the sensor stabilization system to address the problems of sampling and spatial aliasing, something that an AA filter is usually responsible for.
This technology in this patent is for both stills and video, I will note, that understanding this patent isn’t for the faint of heart.
Check out the full patent at the USPTO website.
Interestingly, Canon Rumors reader Nicolas let me know on Twitter that Pentax does something similar. You can check out the demonstration from the Ricoh YouTube channel below.
