Patent ID: 6919909

Claim:
A video display system for displaying an image on a display medium comprising: a first video source means mounted relative to the display medium for displaying a first portion of the image at a first resolution; a second video source means mounted relative to the first video source means and the display medium, for displaying a second portion of the image at a second resolution, the second portion overlaying a subset of the first portion, the second portion moving over the first portion; an image transformer means for generating an input to the second video source means by performing a transform, wherein the input is changeable over time and aligns the second portion to the first portion, the second portion moving over the first portion, the image transformer means comprising: means for determining a first image plane transform by determining a correlation between an image plane corresponding to the first video source means and the display medium; means for determining a plurality of image plane correlations between the display on the display medium of the image plane corresponding to the first video source means and an image plane corresponding to the second video source means, each of the plurality of correlations corresponding to a configuration of the second video source means, wherein the configuration of the second video source means is changeable over time and corresponds to the second portion moving over the first portion; means for determining a second image transform as a function of the configuration of the second video source means, from the first image plane transform and the plurality of image plane correlations; means for providing the input to the second video source means, said input being compensated for relative configurations for the first video source means, the second video source means and the display medium.
