  abstract = {In this paper, we aim to remove the effect of projector defocus. To
	achieve this with uncalibrated projectorcamera pair, we propose a
	method that estimates Point Spread Function from only the displayed
	image on the displayed surface. We focus on the ringing artifacts
	on the restored image. Then we sharpen the original image based on
	Bayes' theorem with the estimated Point Spread Function. To validate
	the proposed method, the experimental result shows that projector
	defocus can be removed by sharpened image projection.}
