IMAGE CORRECTION DATA CALCULATION METHOD, IMAGE CORRECTION DATA CALCULATION APPARATUS, AND MULTI- PROJECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an image correction data calculation apparatus capable of calculating image correction data without the need for complicated operations in the case of processing an image photographed by an image photographing means.

SOLUTION: The image correction data calculation apparatus 11 includes: a calibration pattern display means 15 for generating a calibration pattern and giving it to an image display means 13; the image display means 13 for displaying the calibration pattern; an image photographing means 17 for photographing the calibration pattern displayed on the image display means 13; and an arithmetic means 19 for calculating image correction data from the pattern photographing image obtained by the calibration pattern photographed by the image photographing means 17 and information such as coordinates of the calibration pattern.
