MULTIPLEX PROJECTION CONTROL APPARATUS, MULTIPLEX PROJECTION CONTROL METHOD AND MULTIPLEX PROJECTION CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a multiplex projection control apparatus for erasing a shadow on a screen while projection light to an object is suppressed.

SOLUTION: A camera 1 photographs a video on a screen projected by projectors 7-1 and 7-2. An image input section 2 acquires image data from the camera 1. A frame managing section 3 transfers image information (frame number) used for shadow erasure and illumination suppression. A content DB (database) 4 supplies contents of multiplex projection to shadow region correction sections 5-1 and 5-2 corresponding to the projectors 7-1 and 7-2. The shadow region correction sections 5-1 and 5-2 correct output luminance values of the projectors 7-1 and 7-2 on the basis of the image information (frame number). Projection light suppressing sections 6-1 and 6-2 suppress projection light of the projectors 7-1 and 7-2 to the object.
