Abstract
Method and apparatuses for compensating for perceived blur due to inter-frame motion in a sequence of digital video frames are disclosed. One example method includes blurring a current frame using first and second blurring filters to generate first and second blurred frames, respectively. A first weighted combination of the current frame, the first blurred frame, and the second blurred frame is then blurred with the first blurring filter to generate a third blurred frame. The current frame is combined with the third blurred frame in a second weighted combination to generate a blur-compensated frame.
