A projection system configured to project a first projection image and a second projection image onto a projection surface, with an end portion of the first projection image and an end portion of the second projection image overlapping each other, the projection system comprising:

• a first projector configured to project the first projection image onto the projection surface;
• and
• a second projector configured to project the second projection image onto the projection surface, wherein
• the first projector is configured to acquire first projection image data and a first control signal, the first projection image data representing the first projection image that is a clipping of at least one original projection image, the first control signal being linked to the first projection image data and being for controlling driving of the first projector, and
• the second projector is configured to acquire second projection image data and a second control signal, the second projection image data representing the second projection image that is a clipping of the at least one original projection image, the second control signal being linked to the second projection image data and being for controlling driving of the second projector.
