Patent ID: 6853354

Claim:
A multi-display projector system comprising: a plurality of projectors, each projector comprising: an input format detector for detecting input format parameters from input image signals that have different formats; an input pattern memory for storing the input format parameters that specify a number of active pixels, a number of active lines, an initial active pixel, and an active initial line of the input image signals having different formats, said input format parameters being stored for each of said different formats; a frame memory for storing active image signals extracted from said input image signals based on said input format parameters; a display region calculator for calculating display parameters; a display pattern memory for storing the display parameters, which designate a region of an image to be displayed, each region of the image to be displayed is designated independently of a region designated in the other projectors; and a display unit that displays said region of the image by processing said active image signals stored in said frame memory based on said display parameters.
