PROJECTION SYSTEM, PROJECTOR DEVICE, AND PROGRAM

摘要

The present invention realizes a projection system for easily and appropriately reducing the geometric distortion of an image projected to a projection plane. The projection unit (3) of a projection system (1000) projects a test image to the projection plane. A three-dimensional shape measurement unit (4) measures the three-dimensional shape of the projection plane. A controller (200) generates a control signal. A projection image adjustment unit (1) executes, in accordance with the control signal, a correction process and a rotation process on the test image on the basis of data of the measured three-dimensional shape, so that the geometric distortion of an image is reduced when seen from a user's viewpoint.
