Patent ID: 7679690

Claim:
A geometry correction module for a fixed pixel raster projector to project an image onto a projection surface, the module comprising: a receiver configured to collect an input pixels grid including input pixels arranged to represent an input image, each input pixel including input image data of the input image; and a geometry corrector operatively coupled to the receiver, the geometry corrector configured to generate an output pixels grid including output pixels arranged to represent an output image, each output pixel including output image data, the output pixels arranged in the output pixels grid to compensate for a geometry of the projection surface by repositioning image data interpolated from between at least two input pixels, the output image representing an altered input image that when projected onto the projection surface will display a correctly proportioned input image; and a vignette correction means including a scaling generator in data communication with the geometry corrector, the scaling generator configured to adjust color data of each input pixel based on an interpolated pixel position value of each pixel.
