Abstract:
After calibration of the projector, the control circuit obtains a first position-data indicating the position of a feature point in the screen and a second position-data indicating the position of a feature point in a test image projected onto the screen. After acquisition of the first position-data and the second position-data, the control circuit obtains a third position-data indicating the position of a feature point in the screen and a fourth position-data indicating the position of a feature point in the test image projected onto the screen. Based on a difference between the first position-data and the third position-data, the control circuit corrects the position of a feature point in the test image contained in the fourth position-data to create a fifth position-data. Based on a difference between the second position-data and the fifth position-data, the control circuit recalibrates the projector.

Claim (Index 3):
The calibration device according to  claim 1 , wherein,\n a plurality of markers that emits light under control of the controller is disposed at predetermined four-or-more positions in the projection plane, the controller causes the imaging device to image the projection plane and the plurality of markers, and obtains the predetermined four-or more positions of the plurality of markers as the set of positions of the feature points in the projection plane, the controller obtaining the first position-data and the third position-data.
