Abstract
Provided is a projection system that easily and appropriately reduces the geometric distortion of the image projected on the projection plane. The projection circuitryof the projection systemprojects a test image onto the projection plane. The three-dimensional shape measurement circuitrymeasures the three-dimensional shape of the projection plane. The controllergenerates a control signal. Based on the measured three-dimensional shape data, the projection image adjustment circuitryperforms correction processing and rotation processing on a test, in accordance with the control signal, such that the geometrical image distortion is reduced as viewed from the user's viewpoint.
