Abstract

Claims (52)

1 . A projection system configured to project a first projection image and a second projection image onto a projection surface, with a portion of the first projection image and a portion of the second projection image overlapping each other, the projection system comprising:

a first projector configured to project the first projection image onto the projection surface; and

a second projector configured to project the second projection image onto the projection surface,

wherein the first projector is configured to acquire first projection image data and a plurality of first control signals, the first projection image data representing the first projection image that is a clipping of a plurality of types of original projection images, the first control signals being linked to the first projection image data to control driving of the first projector,

wherein the second projector is configured to acquire second projection image data and a plurality of second control signals, the second projection image data representing the second projection image that is a clipping of the plurality of types of original projection images, the second control signals being linked to the second projection image data to control driving of the second projector,

wherein the plurality of first control signals correspond to the plurality of types of original projection images, respectively, and

wherein the plurality of second control signals correspond to the plurality of types of original projection images, respectively.

2 . The projection system according to claim 1 , wherein:

the first projector includes a first reception unit configured to receive first command data from an external controller,

the second projector includes a second reception unit configured to receive second command data from the external controller,

the first command data includes:

a plurality of first image clipping commands configured to instruct the first projector to clip the first projection image from the plurality of types of original projection images to obtain the first projection image data, and

a plurality of first control commands configured to instruct the first projector to generate the plurality of first control signals,

the second command data includes:

a plurality of second image clipping commands configured to instruct the second projector to clip the second projection image from the plurality of types of original projection images to obtain the second projection image data, and

a plurality of second control commands configured to instruct the second projector to generate the plurality of second control signals,

the first projector is configured to generate the first projection image data and the plurality of first control signals based on the first command data, and

the second projector is configured to generate the second projection image data and the plurality of second control signals based on the second command data.

3 . The projection system according to claim 2 , wherein:

the plurality of first image clipping commands correspond to the plurality of types of original projection images, respectively,

the plurality of first control commands correspond to the plurality of types of original projection images, respectively,

the plurality of second image clipping commands correspond to the plurality of types of original projection images, respectively, and

the plurality of second control commands correspond to the plurality of types of original projection images, respectively.

4 . The projection system according to claim 3 , wherein the plurality of first image clipping commands and the plurality of first control commands are commands for controlling the first projector at temporally different timings.

5 . The projection system according to claim 4 , wherein:

the plurality of first image clipping commands are commands having identical content, and

the plurality of first control commands are commands having mutually different content.

6 . The projection system according to claim 3 , wherein the plurality of second image clipping commands and the plurality of second control commands are commands for controlling the second projector at temporally different timings.

7 . The projection system according to claim 6 , wherein:

the plurality of second image clipping commands are commands having identical content, and

the plurality of second control commands are commands having mutually different content.

8 . The projection system according to claim 2 , wherein:

each of the plurality of first image clipping commands and each of the plurality of second image clipping commands includes position coordinates in the plurality of types of original projection images, and

the position coordinates of the plurality of first image clipping commands are different from the position coordinates of the plurality of second image clipping commands.

9 . The projection system according to claim 3 , wherein:

the first command data further includes a device command for controlling a device other than projectors including the first projector and the second projector, and

the device command is linked to one of the plurality of types of original projection images.

10 . The projection system according to claim 9 , wherein:

the device command includes a plurality of device commands, and

the plurality of device commands are linked to the plurality of types of original projection images, respectively.

11 . The projection system according to claim 1 , wherein:

the first projector is configured to acquire the first projection image data and the plurality of first control signals via a media server, and

the second projector is configured to acquire the second projection image data and the plurality of second control signals via the media server.

12 . The projection system according to claim 11 , wherein:

the first projector is configured to acquire a signal for operating the plurality of first control signals via the media server, and

the second projector is configured to acquire a signal for operating the plurality of second control signals via the media server.

13 . A control method for a projection system configured to cause a first projector and a second projector to project a first projection image and a second projection image onto a projection surface, respectively, with a portion of the first projection image and a portion of the second projection image overlapping each other, the control method comprising:

(a) obtaining first projection image data and second projection image data, the first projection image data representing the first projection image that is a clipping from a plurality of types of original projection images, the second projection image data representing the second projection image that is a clipping from the plurality of types of original projection images;

(b) transmitting the first projection image data and a plurality of first control signals to the first projector, the plurality of first control signals being linked to the first projection image data to control driving of the first projector; and

(c) transmitting the second projection image data and a plurality of second control signals to the second projector, the plurality of second control signals being linked to the second projection image data to control driving of the second projector,

wherein the plurality of first control signals correspond to the plurality of types of original projection images, respectively, and

wherein the plurality of second control signals correspond to the plurality of types of original projection images, respectively.
