| 1. A parallax correction method comprising the steps of:
upsampling corresponding regions of first and second digital images of the same scene to provide a pair of upsampled regions,
said corresponding regions having parallax;
statistically comparing said upsampled regions at a plurality of relative subpixel offsets to provide a corresponding plurality
of similarity values, said similarity values defining a peak similarity value and a corresponding peak subpixel offset among
said plurality of relative subpixel offsets; and
shifting said second digital image relative to said first digital image by said peak subpixel offset.
