Abstract
This invention is directed to a system and method for creating characterization information and a correction map from a first display grid that can be transmitted and used by a second display grid. Computer readable instructions embodied in a computer readable medium calibrate a first display grid and create an ICC color profile and correction map from said calibration information, such that an image to be displayed across an entire display grid which is segmented into portions corresponding to each display device in the display grid is displayed with uniform luminance and color across the entire display grid. The invention can then store the correction map and characterization information and send the information to a second display device for it to use. Alternatively, the calibration or characterization information can be associated with an image file and sent to a second location for display.
