摘要： 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.

摘要： Digital correction module for video projector where a correction module is provided to give a non-linear re-imaging of an image so that it is displayed correct on a non-ideal screen (curved screen) where a correction module is provided in each of a plurality of video projectors after a common image source in order to create a large, of several composite sub image, projected image of said image source. The correction module comprises a sequencer (1), a pixel write control (2), a parameter storage (7), a read address generator (13), a coefficient generator (5), a scaling generator (6), an adder (8), a pixel storage (3), a vertical mixer (9), a horizontal mixer (10) and a look up function means (12) for correction of differences in the border area of the image of the respective projectors such as geometry correction, soft transition tuning, vignette correction and gamma correction.
