Image transfer method, image transfer system, and projector

An image transfer system which supplies image data to a plurality of projectors from an image supply unit via a network, comprising:

• an image supply unit supplying image data;
• and
• a plurality of projectors which project an image based on the image data, wherein
• the image supply unit includes
• a transmission destination information list generating section generating a transmission destination information list for determining a transmission destination of the image data,
• a transmission destination determining section determining, based on the transmission destination information list, a transmission destination projector to which the image data is transmitted, and
• a transmitting section transmitting the image data and the transmission destination information list to the transmission destination projector determined by the transmission destination determining section, and
• the projector includes
• a receiving section receiving the image data and the transmission destination information list including a plurality of projectors as a transmission destination from the image supply unit or another projector,
• a transmission destination determining section determining, based on the transmission destination information list, one projector of the plurality of projectors,
• a transmission destination information list updating section updating the transmission destination information list,
• a transmitting section transmitting the updated transmission destination information list to the projector thus determined along with the image data, and
• a projecting section projecting an image based on the image data.

A projector comprising:

• a receiving section receiving image data and a transmission destination information list including at least one projector as a transmission destination from an image supply unit or another projector;
• a transmission destination determining section determining one projector of a plurality of projectors based on the transmission destination information list;
• a transmission destination information list updating section updating the transmission destination information list;
• a transmitting section transmitting the updated transmission destination information list to the projector thus determined along with the image data;
• and
• a projecting section projecting an image based on the image data.
