We integrate coded apertures into off-the-shelf projectors to increase their focal depth. The regional defocus of the projection on the surface is measured automatically. The projected images are then deconvolved with locally scaled aperture codes. This leads to significantly better results than deconvolving with Gaussians in cases where regular spherical apertures are used.
