摘要： A method of producing a digital image with reduced object motion blur, includes capturing at least a first and second digital image of a scene using an exposure time that reduces image blur; combining pixels of the first digital image to produce a third digital image which is brighter than the first and second digital images and has a lower resolution than either the first or second digital images; identifying static and moving regions between the first and second digital images; operating on the first and second digital images to produce a fourth digital image which is brighter than the first and second digital images and has object motion blur; and replacing the moving regions in the fourth digital image with corresponding regions from the third digital image to thereby provide a fifth digital image with reduced object motion blur and increased brightness.
