PROBLEM TO BE SOLVED: To adjust each projector by a simple operation, when projecting the same image on a screen by several projectors. SOLUTION: A communication control part 4 controls serial communication executed between itself and an outside device through a serial communication port P1 or P2. A control part 8, when receiving a stack definition packet through the serial communication port P1, houses ID information in a memory 7 based on number information included therein, and transmits the number information of the stack definition packet incrementally from the serial communication port P2. The control part 8, when receiving a command through the serial communication port P1, judges whether it is a command for the concerned projector or not, based on address information included therein and the ID information housed in the memory 7, and in the case of yes, executes processing corresponding to the command. |
