A projector control system, comprising:
- a location measurement unit configured to
- measure a distance and an angle between a first projector and a second projector, and
- measure location information based on the distance and the angle, the location information comprising coordinates of a location of the second projector that is mapped on a coordinate plane centered on coordinates of a location of the first projector;
- a projection information unit configured to generate projection information based on the location information, the projection information comprising first projection information corresponding to the first projector, and second projection information corresponding to the second projector;
- a communication unit configured to transmit the second projection information to the second projector;
- an image division information unit configured to
- divide an image into a first sub-image and a second sub-image, and
- generate first sub-image information and second sub-image information that correspond to the first and second sub-images, respectively, the first projection information comprising the first sub-image information and coordinates of a location where the first sub-image is projected by the first projector on the coordinate plane, and the second projection information comprising the second sub-image information and coordinates of a location where the second sub-image is projected by the second projector on the coordinate plane;
- and an image control unit configured to
- project the first sub-image based on the first sub-image information to the location corresponding to the coordinates included in the first projection information, and
- control the second projector to project the second sub-image based on the second sub-image information to the location corresponding to the coordinates included in the second projection information.
