Abstract

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