シフトされた重ね合わせを使用したリアルタイム空間ベースの解像度向上

摘要

PROBLEM TO BE SOLVED: To provide a projection system for projecting an image with an increased apparent resolution.;SOLUTION: The projection system includes one or more projectors, a resampler module, and a deconvolution module. The resampler module is configured to upsample an incoming high-resolution signal, perform an integer shift operation on a signal, and downsample to two or more low-resolution signals. The deconvolution module is configured to filter the upsampled 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. Preferably, the spatial domain deconvolution operation uses an N×N spatial kernel obtained from a spatial domain approximation of a Wiener filter.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
