Abstract
A remote controller respectively transmits an infrared operation signal to a projector, a Bluetooth operation signal to an image supply apparatus, and both the operation signals when respective operation keys of first, second, and third key groups are operated. When a menu key is operated, the projector performs control for displaying a menu image and output of an operation restricting command to the image supply apparatus, and, when a predetermined condition is satisfied after the output of the operation restricting command, performs control for ending the display of the menu image and output of a restriction releasing command to the image supply apparatus. The image supply apparatus stops control corresponding to an operation signal corresponding to the third key group from when the operation restricting command is input until when the restriction releasing command is input.
