Abstract
A method and apparatus for reducing motion blur in digital images. An imager captures a reference frame and a plurality of target frames. Feature blocks preferably containing strong two-dimensional features are identified in the reference frame. Corresponding features are identified in the target frames and motion vectors representing the movement of features are calculated. Based at least in part on the motion vectors, corresponding pixels in the reference and target frames are identified and combined to form an output image. Efficient methods for identifying corresponding features in apparatuses with small buffer memories by serially processing frame strips are also disclosed.
