Abstract
An image correction data calculation apparatus of the invention includes a calibration pattern display unit for creating and supplying a calibration pattern, an image display unit for displaying the calibration patterns supplied thereto, an image capturing unit for capturing the calibration patterns displayed on the image display unit, and an arithmetic operation unit for calculating image correction data based on pattern-captured images obtained by capturing the calibration patterns and based on pattern information including information such as the pattern-captured images obtained by capturing the calibration patterns, the coordinates of the calibration patterns, and the like.

An image correction data calculation method of calculating image correction data for aligning the positions of images projected from a plurality of projectors comprising:
- a display step for supplying a calibration pattern to each of the projectors by calibration pattern display means and displaying the calibration patterns from the respective projectors on a screen;
- an image capturing step for capturing the calibration patterns displayed at the display step by image capturing means as pattern-captured images;
- and
- an arithmetic operation step for calculating the image correction data based on the pattern-captured images obtained at the image capturing step and based on previously applied pattern information including the coordinate information of the calibration pattern.
An image correction data calculation apparatus for calculating image correction data for aligning the positions of images projected from a plurality of projectors comprising:
- calibration pattern display means for creating and supplying a calibration pattern;
- image display means for displaying the calibration patterns supplied from the calibration pattern display means;
- image capturing means for capturing the calibration patterns displayed on the image display means;
