ABSTRACT:
To provide a technique for facilitating control of a plurality of projectors. A projection display system comprises a plurality of projectors wherein a plurality of images projected by the projectors are displayed on a common projection screen. Each projector comprises: a control signal processor for processing a control signal given from an external device and generating a processed control signal; and a signal input/output section for input/output of the control signal and the processed control signal. The plurality of projectors are coupled in a cascade connection, by interconnecting the signal input/output sections of the projectors. The control signal and the processed control signal include connection sequence data indicating the cascade connection sequence. The control signal processor of each projector comprises a memory for storing, on the basis of a given control signal, a connection sequence when the projectors are coupled in a cascade connection.
