SOLUTION: A screen system 100 includes: the air screen 110 provided with a flight means to be operated in response to a given command and a communication means; a base station 121 having a measurement system for measuring the position of the air screen 110, a communication means for communicating with the air screen 110, and a control system; and a projector 123 for irradiating the air screen 110 with light. The control system comprises a command generating means for generating a flight command to control the flight of the air screen 110 in response to the position of the air screen 110 measured by the measurement system.
