Abstract
A projector includes a first projection unit that projects a first image, a first imager that captures a second image projected by another projector, and a first calculation unit. The first calculation unit calculates, from captured image data of the second image captured by the first imager and interval information indicating an interval between the other projector and the projector, a first distance between a surface on which the second image is projected and the other projector, or a second distance between an area in which the second image is projected and the projector. The first projection unit controls projection of the first image based on the first distance or the second distance.
Claims17
A projector comprising:
- a first projection unit that projects a first image;
- a first imager that captures a second image projected by another projector;
- and
- a first calculation unit that calculates, from captured image data of the second image captured by the first imager and interval information indicating an interval between the other projector and the projector, a first distance between a surface on which the second image is projected and the other projector, or a second distance between an area in which the second image is projected and the projector,
- wherein the first projection unit controls projection of the first image based on the first distance or the second distance.
A projector system comprising:
- a first projector that projects a first image;
- a second projector that projects a second image;
- and
- a control box that performs communication with the first projector and the second projector,
- wherein
- the first projector includes
- a first projection unit that projects the first image,
- a first imager that captures the second image, and
- a first communication unit that transmits position information of the first projector and captured image data of the second image captured by the first imager,
- the second projector includes a second communication unit that transmits position information of the second projector,
- the control box includes
- a third communication unit that receives the position information of the first projector and the captured image data from the first communication unit, and receives the position information of the second projector from the second communication unit, and
- a third calculation unit that calculates, from the position information of the first projector and the position information of the second projector, interval information indicating an interval between the first projector and the second projector, and calculates, from the captured image data and the interval information, a first distance between a surface on which the second image is projected and the second projector, or a second distance between an area in which the second image is projected and the first projector, and
- the control box controls projection of the first image by the first projection unit based on the first distance or the second distance.
A projector system comprising:
- a first projector that projects a first image;
- a second projector that projects a second image;
- an imaging device that captures the second image;
- and
- a calculation unit that calculates, from captured image data of the second image captured by the imaging device and position information of the first projector, the second projector, and the imaging device, a first distance between a surface on which the second image is projected and the second projector, or a second distance between an area in which the second image is projected and the imaging device,
- wherein the first projector controls projection of the first image based on the first distance or the second distance.
