Abstract
A projector that projects an image includes a communication section that sends a projection request command that requests another projector connected to the projector to project a test image, an imaging section that captures an image of the test image projected in response to the projection request command by the another projector, and a layout recognition section that recognizes a relative layout relationship between the projector and the another projector based on the image captured by the imaging section.
Claims11
A projector that projects an image, the projector comprising:
- a communication section that sends a projection request command that requests another projector connected to the projector to project a test image;
- an imaging section that captures an image which contains at least part of the test image projected by the other projector in response to the projection request command, wherein the captured image is divided into a plurality of divided regions;
- and
- a layout recognition section that recognizes a relative layout relationship between the projector and the other projector by determining which of the divided regions contains the at least part of the test image in the image captured by the imaging section;
- and
- a layout information creation section that creates layout information representing the relative layout relationship between the projector and the other projector based on the relative layout relationship recognized by the layout recognition section,
- wherein
- the communication section sends a first command for checking for the presence of other projectors connected to the projector, and
- the layout information is initialized in response to the communication section receiving a second command from the other projector in response to the other projector receiving the first command.
A method for controlling a projector that projects an image, the method comprising:
- sending a first command for checking for the presence of other projectors connected to the projector;
- receiving a second command from another projector in response to the other projector receiving the first command;
- initializing layout information in response receiving the second command;
- first-capturing an image of a test image projected by the projector;
- sending a projection request command that requests another projector connected to the projector to project a the test image;
- second-capturing an image which contains at least part of the test image projected by the other projector in response to the projection request command, wherein the image captured in the second-capturing is divided into a plurality of divided regions;
- and
- recognizing a relative layout relationship between the projector and the other projector by determining which of the divided regions contains the at least a part of the test image in the image captured in the second-capturing
- creating layout information representing the relative layout relationship between the projector and the other projector based on the recognized relative layout relationship.
