20100039562 | Source and output device-independent pixel compositor device adapted to incorporate the digital visual interface (DVI) - A pixel compositor device for routing an incoming stream of pixel data having been rendered elsewhere and bound for being projected. The device includes a plurality of digital signal inputs each adapted for receiving a plurality of pixel information from the incoming stream of pixel data. The digital signal inputs are in communication with at least one buffer for the pixel information once received by the device. A processing unit is included for image warping the pixel information by performing, on each of a respective of the pixel information: (i) a mapping relating to location of the respective pixel information, and (ii) a scaling function. The geometric mapping can be performed by applying an interpolation technique; and the scaling function can be any of a number of photometric correction functions (alpha-blending, color uniformity correction, image brightness or contrast adjustment, etc.). Once an image warping has been performed on the respective pixel information, it is routed out of the device through one of several digital signal outputs. A system for routing pixel data is disclosed having two or more of the pixel compositor devices in communication with an image rendering cluster of units (as the source of the incoming stream of pixel data) and a plurality of projectors; as is a method for routing an incoming stream of pixel data having been rendered elsewhere and bound for being projected. | 02-18-2010 |
