摘要：
A projector can be connected in cascade to another projector. Either a first mode for the projector to operate as a leading projector in the cascade connection or a second mode for the projector to operate as a second or subsequent projector in the cascade connection is set. The projector is made available for use on authentication by an authentication unit or on reception of use permission information of the projector by a receiving unit.
