Abstract: A system for correcting the intensities of pixels supplied to a projector. An image generated by the projector has a number of regions formed by the overlapping of the image with one or more other images generated by one or more other projectors. The system includes: a first unit configured to generate a horizontal scaling value; a second unit configured to generate a vertical scaling value; a first multiplier configured to multiply the horizontal scaling value and the vertical scaling value to obtain a scaling coefficient, and a set of one or more additional multipliers configured to multiply components of an input pixel by the scaling coefficient to determine components for an output pixel. The first unit and second unit compute their respective scaling values in a way that allows for regions whose boundaries non-aligned in the vertical direction.

Abstract: A video image tracking system is provided for determining the orientation of an operator with respect to a simulator display. The operator carries an observation device for watching the simulator display which has a detectable object disposed therein. The video image tracking system further includes a device for locating the detectable object within the simulator display and communicates this location to a virtual reality system which displays the proper orientation and location of the virtual environment with respect to the operator. The video image tracking system is incorporated into a virtual environment deployable simulator which has an environment system for including virtual reality effects into a plurality of color keys contained within the simulator display.
