PROBLEM TO BE SOLVED: To provide a projection system that can project images with a wide angle and good resolution.SOLUTION: An image conversion device 55 performs geometrical correction of an image to be projected by a projection device 20, in association with the movement of a projection target body 60 by a lifting device 30 and a change in the projection direction of the projection device 20 by a depression angle device 40, on the basis of the positional relationship between the projection direction and the projection target body 60. |
