Non-linear image mapping using a plurality of non-coplanar clipping planes
First Claim
1. A display processing system for providing video signals for displaying an image, comprising input channels for receiving a plurality of component images, each component image being a portion of the complete image for display, the image data of each component image being defined by an view frustum having a clipping plane, and a combiner for combining the image data of the component images, wherein at least two clipping planes of two of the view frustums are non-coplanar.

Abstract
A display processing system for providing video signals for displaying an image is provided. The display processing system comprises input channels for receiving a plurality of component images, each component image being a portion of the complete image for display, the image data of each component image being defined by a view frustum having a clipping plane, and a combiner for combining the image data of the component images. According to the present invention, at least two clipping planes of two of the view frustums are non-coplanar. Such display processing system corrects for the defect of driving angular resolution to the edges of the field of view of a display system, in particular for large field-of-view display systems, and balances the overall system angular resolution by allowing each image generator channel to render to an optimal view frustum for its portion of the complete image.
