Abstract
A projector comprises a projection unit, an image pickup unit, a control unit, and a correction unit. The projection unit is configured to project a video based on a video signal. The 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. The control unit is configured to determine a projection video projected by the other projector based on the picked-up image received from the image pickup unit. The correction unit is configured to carry out 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 the other projector based on the picked-up image received from the image pickup unit;
- and
- a correction unit configured to carry out 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 the projection video projected by the projector and outputting the picked-up image;
- determining a projection video projected by the other projector based on the picked-up image;
- and carrying out 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 correction unit configured to carry out 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 the other projector based on the picked-up image received from the image pick up unit;
- and
- causing the correction unit to carry out 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.
