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.
