Abstract
An image projection apparatus obtains a first partial image, which is a part of a projection target image. The image projection apparatus also receives, from another image projection apparatus, a first overlap image that is a portion of an image corresponding to a predetermined overlap area in which a projected image that the image projection apparatus projects and a projected image projected by another image projection apparatus overlap with each other, and that is not included in the first partial image. Then, the image projection apparatus projects a combined image obtained by combining the received first overlap image and the first partial image.
Claims18
An image projection apparatus for projecting a projection target image by overlapping a projected image that the image projection apparatus projects with a projected image projected by another image projection apparatus on a projection plane, comprising:
- an obtaining unit which is able to obtain a first partial image that is a part of the projection target image;
- a reception unit which is able to receive, from the other image projection apparatus, a first overlap image that is a portion of an image corresponding to a predetermined overlap area in which the projected image that the image projection apparatus projects and the projected image projected by the other image projection apparatus overlap with each other, and that is not included in the first partial image;
- and
- a projection unit which is able to project a combined image obtained by combining the first overlap image received by the reception unit and the first partial image.
An image projection apparatus for projecting a projection target image by overlapping a projected image that the image projection apparatus projects with a projected image projected by another image projection apparatus on a projection plane, comprising:
- an obtaining unit which is able to obtain a partial image that is a part of the projection target image;
- a transmission unit which is able to transmit, to the other image projection apparatus, an overlap image that is a portion of an image corresponding to a predetermined overlap area in which the projected image that the image projection apparatus projects and the projected image projected by the other image projection apparatus overlap with each other, and that is included in the partial image;
- and
- a projection unit which is able to project the partial image.
A method for controlling an image projection apparatus for projecting a projection target image by overlapping a projected image that the image projection apparatus projects with a projected image projected by another image projection apparatus on a projection plane, the method comprising:
- an obtaining step of obtaining a first partial image that is a part of the projection target image, by an obtaining unit in the image projection apparatus;
- a reception step of receiving, from the other image projection apparatus, a first overlap image that is a portion of an image corresponding to a predetermined overlap area in which the projected image that the image projection apparatus projects and the projected image projected by the other image projection apparatus overlap with each other, and that is not included in the first partial image, by a reception unit in the image projection apparatus;
- and
- a projection step of projecting a combined image obtained by combining the first overlap image received in the reception step and the first partial image, by a projection unit in the image projection apparatus.
A method for controlling an image projection apparatus for projecting a projection target image by overlapping a projected image that the image projection apparatus projects with a projected image projected by another image projection apparatus on a projection plane, the method comprising:
- an obtaining step of obtaining a partial image that is a part of the projection target image, by an obtaining unit in the image projection apparatus;
- a transmission step of transmitting, to the other image projection apparatus, an overlap image that is a portion of an image corresponding to a predetermined overlap area in which the projected image that the image projection apparatus projects and the projected image projected by the other image projection apparatus overlap with each other, and that is included in the partial image, by a transmission unit in the image projection apparatus;
- and
- a projection step of projecting the partial image, by a projection unit in the image projection apparatus.
A projection system for projecting a projection target image by overlapping a first projected image projected by a first image projection apparatus and a second projected image projected by a second image projection apparatus with each other, on a projection plane,
- the first image projection apparatus comprising:
- a first obtaining unit which is able to obtain a first partial image that is a part of the projection target image;
- a reception unit which is able to receive, from the second image projection apparatus, a first overlap image that is a portion of an image corresponding to a predetermined overlap area in which the second projected image and the first projected image overlap with each other, and that is not included in the first partial image;
- and
- a first projection unit which is able to project a combined image obtained by combining the first overlap image received by the reception unit and the first partial image,
- the second image projection apparatus comprising:
- a second obtaining unit which is able to obtain a second partial image that is a part of the projection target image;
- a transmission unit which is able to transmit, to the first image projection apparatus, an image that is a portion of the image corresponding to the overlap area and is included in the second partial image, as the first overlap image;
- and
- a second projection unit which is able to project the second partial image.
