Abstract
Provided is a projection system that easily and appropriately reduces the geometric distortion of the image projected on the projection plane. The projection circuitry 3 of the projection system 1000 projects a test image onto the projection plane. The three-dimensional shape measurement circuitry 4 measures the three-dimensional shape of the projection plane. The controller 200 generates a control signal. Based on the measured three-dimensional shape data, the projection image adjustment circuitry 1 performs 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.
