Patent ID: 8547442

Claim:
A method for motion blur and ghosting prevention in an imaging system, comprising: inputting an input image set containing a plurality of Bayer raw images, the plurality of Bayer raw images having different exposures; computing an absolute difference of image pairs in radiance domain to generate a set of image differences; computing an initial residue image using a spatial-temporal filter with the set of image differences; applying a maximum filter to the initial residue image to obtain a residue image; computing the residue image from the plurality of Bayer raw images; computing a noise adaptive pixel threshold set from the plurality of Bayer raw images; creating a motion masking map for one of assigning and not assigning each pixel position as “MOTION” using the residue image and the noise adaptive pixel threshold set; merging pixels from the input image set if the motion masking map at the pixel position is not assigned “MOTION”; designating a pixel value of an input image of the input image set if the motion masking map at the pixel position is assigned “MOTION”; and selecting one of said merging and said designating based on the motion masking map at each pixel position to generate an output image.
