  • Digital correction module for video projector
    Patent number: 7855753
    Abstract: A geometry correction module for a fixed pixel raster projector to project an image onto a projection surface is provided. The geometry correction module includes a receiver and a geometry corrector. The receiver collects an input pixels grid that represents an input image. The geometry corrector generates an output pixels grid representing an output image that compensates for the geometry of the projection surface by repositioning image data interpolated from at least two input pixels. The output image represents an altered input image that when projected onto the projection surface will display a correctly proportioned input image. A method of correcting geometry distortion when projecting an image is also provided.
