1. A device implemented method of using deconvolution to deblur a blurred digital image, the method comprising: computing a local two-color model of the blurred image, the two-color model modeling the pixels of the image as respective local combinations of two colors; generating a deblurred image corresponding to the blurred image by deconvolving the image with a blur kernel using the two-color model as a prior to constrain the deconvolution.
