Abstract
In at least one embodiment, a projector comprises a projection unit configured to project a video based on a video signal. An image pickup unit is configured to pick up an image of a projection video projected by the projection unit and output the picked-up image. A control unit is configured to determine a projection video projected by an other projector based on the picked-up image received from the image pickup unit. A keystone correction unit is configured to carry out keystone correction of the video signal so that the projection video projected by the projection unit is aligned with the projection video projected by the other projector.
Claims8
A projector comprising:
- a projection unit configured to project a video based on a video signal;
- an image pickup unit configured to pick up an image of a projection video projected by the projection unit and output the picked-up image;
- a control unit configured to determine a projection video projected by an other projector based on the picked-up image received from the image pickup unit;
- and
- a keystone correction unit configured to carry out keystone correction of the video signal so that the projection video projected by the projection unit is aligned with the projection video projected by the other projector.
A projector control method for controlling a projector which projects a video based on a video signal, the control method comprising:
- picking up an image of a projection video projected by the projector and outputting the picked-up image;
- determining a projection video projected by an other projector based on the picked-up image;
- and
- carrying out keystone correction of the video signal so that the projection video projected by the projector is aligned with the projection video projected by the other projector.
A projector control method for controlling a projector comprising a keystone correction unit configured to carry out keystone correction of a video signal, a projection unit configured to project a video based on the video signal, and an image pickup unit configured to pick up an image of an image pickup object, the method comprising:
- causing the image pickup unit to pick up an image of a projection video projected by the projection unit and to output the picked-up image;
- determining a projection video projected by an other projector based on the picked-up image received from the image pick up unit;
- and
- causing the keystone correction unit to carry out keystone correction of the video signal so that the projection video projected by the projection unit is aligned with the projection video projected by the other projector.
