Patent ID: 8702246

Claim:
A control apparatus for controlling a plurality of projector apparatuses projecting an image, comprising: an input unit configured to input layout information relating to a layout of projection areas to be projected by the plurality of projector apparatuses; an obtaining unit configured to obtain capability information relating to capabilities of the plurality of projector apparatuses; a control unit configured to associate the projection areas with the plurality of projector apparatuses based on the layout information and the capability information such that a first projection area is associated with a first projector apparatus and a second projection area is associated with a second projector apparatus whose capability is lower than that of the first projector apparatus, wherein the first projection area is nearer to the center of the projection areas to be projected by the plurality of projector apparatus than the second projection area; a determination unit configured to determine a correction amount of the plurality of projector apparatuses based on observed projection areas projected by the plurality of projector apparatuses and the projection areas associated with the plurality of projector apparatuses such that a correction amount for the first projector apparatus is determined based on a first observed projection area projected by the first projector apparatus and the first projection area associated with the first projector apparatus and a correction amount for the second projector apparatus is determined based on a second observed projection area projected by the second projector apparatus and the second projection area associated with the second projector apparatus; and a notifying unit configured to notify the plurality of projector apparatuses of correction amounts determined by the determination unit.
