1. A system for projecting an image comprising: a resampler circuit configured to receive a high-resolution signal, upsample the high-resolution signal, perform an integer shift operation and downsample to two or more low-resolution signals; one or more projectors configured to receive the two or more low-resolution signals and superimpose the two or more low-resolution signals to project the image with an increased display resolution; and a deconvolution circuit configured to filter the high-resolution signal using a spatial domain deconvolution operation, the spatial domain deconvolution operation approximating frequency domain optical corrections based on characteristics of the one or more projectors, wherein the spatial domain deconvolution operation uses a deconvolution spatial kernel comprising a spatial approximation of a frequency domain Wiener deconvolution filter for optical corrections based on characteristics of the one or more projectors, and the deconvolution spatial kernel is generated by: estimating a point spread function of the one or more projectors; constructing a Wiener filter based on the point spread function; and generating a spatial domain Wiener filter by applying an inverse Fourier transform of the Wiener filter and extracting a spatial kernel.
