    摘要: A method for reducing noise in an image captured using a digital image sensor having pixels being arranged in a rectangular minimal repeating unit, comprising: computing first weighted pixel differences by combining first pixel differences between the pixel value of a central pixel and pixel values for nearby pixels of the first channel in a plurality of directions with corresponding local edge-responsive weighting values; computing second weighted pixel differences by combining second pixel differences between pixel values for pixels of at least one different channel in the plurality of directions with corresponding local edge-responsive weighting values; and computing a noise-reduced pixel value for the central pixel by combining the first and second weighted pixel differences with the pixel value for the central pixel.

    摘要: A method for reducing noise in a color image captured using a digital image sensor having pixels being arranged in a rectangular minimal repeating unit. The method comprises, for a first color channel, determining noise reduced-pixel values using a first noise reducing process that includes computing weighted pixel differences by combining the pixel differences with corresponding local edge-responsive weighting values. The method further comprises a second noise reducing process that includes computing weighted chroma differences by combining chroma differences with corresponding local edge-responsive weighting values.

    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.
