Abstract
A method for automatic delivery of consistent imagery in a multi-projector system includes the steps of dividing the projectors into a plurality of sub-groups of projectors, each projector oriented to project a sub-frame to a sub-group display location, and adjusting the output of each projector in each sub-group to provide selected target display characteristics across all sub-groups.
