Abstract
An image display system includes a first projector and a second projector, and makes the first projector and the second projector operate in cooperation with each other to form a single projection image on a common screen. The first projector and the second projector are connected to each other via a signal line. A master control section of the first projector transmits a control signal to a subordinate control section of the second projector. The subordinate control section of the second projector controls a projection section of the second projector based on the control signal. Thus, the controllability of the image display system provided with a plurality of projectors is enhanced.
Claims13
A projector comprising:
- a projection section adapted to display a projection image, which is to be combined with a projection image of another projector, by projection on a projection surface;
- and
- a control section adapted to control the projection section, and to transmit a control signal adapted to control the projection of the another projector to the another projector.
A projector comprising:
- a projection section adapted to project an image based on a signal on a projection surface;
- and
- a control section adapted to receive a control signal from another projector, and to control the projection section based on the control signal.
An image display system comprising:
- a first projector;
- and
- a second projector,
- wherein the first and second projectors form projection images on a common projection surface in cooperation with each other,
- the first projector includes
- a first projection section adapted to display the projection image, which is to be combined with the projection image projected by the second projector, by projection on the common projection surface, and
- a master control section adapted to control the first projection section, and to transmit a control signal adapted to control the projection of the second projector to the second projector, and
- the second projector includes
- a second projection section adapted to project an image based on an image signal on the common projection surface, and
- a subordinate control section adapted to receive the control signal from the first projector, and to control the second projection section based on the control signal.
A method of controlling a projector, comprising:
- receiving a control signal from another projector, and projecting an image represented by an image signal on a projection surface based on the control signal.
A method of controlling a projector, comprising:
- (a) displaying a projection image, which is to be combined with a projection image of another projector displayed on a projection surface, by projection on the projection surface;
- and
- (b) transmitting a control signal adapted to control the projection of the another projector to the another projector.
