Minimizing image blur in an image projected onto a display surface by a projector

摘要

A method for minimizing image blur in an image projected onto a display surface by a projector, the image blur being caused by out-of-focus regions, the method comprising: estimating ( 10 ) a spatially varying point-spread-functions (PSF) profile for a test image projected by the projector; and pre-conditioning ( 11 ) the image using a predetermined pre-processing algorithm based on the estimated PSF profile; wherein the pre-conditioned image is projected ( 17 ) by the projector to minimise image blur.
