Pre-Correction of Projected Images for Deblurring on Projector Screen

Abstract We propose a method for reducing out-of-focus blur caused by projector projection. We estimate the Point-Spread-Function (PSF) in the image projected onto the screen by using a camera that captures the projector screen. According to the estimated PSF, the original image is pre-corrected, so that the projected image can be deblurred. Experimental results show proposed method can reduce out-of-focus projection blur
