PROBLEM TO BE SOLVED: To omit a power cable connected to a sensor on a projection plane.SOLUTION: A projection system 100 includes a projector 1 that projects an image onto a projection plane F of a screen S, and sensor units 30a and 30b each including a photoelectric power generating unit 35 that is installed at a predetermined position in an area in which an image is projected on the projection plane F and that generates power corresponding to an intensity of projection light projected by the projector 1. The projector 1 may include an image processing circuit 11 that converts at least image data projected at the installation positions of the sensor units 30a and 30b out of image data projected on the projection plane F into white image data or converts whole image data into white image data.
