Projection image adjustment system and projection image adjustment method

A projection image adjustment system, comprising:

• a plurality of projectors including a first projector, a second projector and a third projector, each of the first, second and third projectors configured to project a first projection image, a second projection image and a third projection image, respectively, on a projection screen, each of the first projector, the second projector and the third projector are distinct from each other;
• a first camera configured to capture a plurality of first projection images projected on the projection screen, the plurality of first projection images including at least the first projection image;
• a second camera configured to capture a plurality of second projection images projected on the projection screen, the plurality of second projection images including at least the third projection image which is not included in the plurality of first projection images captured by the first camera;
• a display unit configured to display an image captured by the first camera or the second camera;
• and a controller configured to control the plurality of projectors, the first camera, and the second camera, wherein the controller is further configured to:
• accept a selection of one of the first camera and the second camera as a selected camera;
• set a first charge-of-shoot region and a second charge-of-shoot region, the first camera being in charge of shooting the first charge-of-shoot region including the first projection image being projected by the first projector and the second projection image being projected by the second projector, the second camera being in charge of shooting the second charge-of-shoot region including the second projection image being projected by the second projector and the third projection image being projected by the third projector;
• project a first format pattern by using the plurality of projectors that project the plurality of the first or the second projection images captured by the selected camera;
• display on a display unit an image of the first charge-of-shoot region or an image of the second charge-of-shoot region, captured by the selected cameras, select a camera layout for the first camera and the second camera based on a layout configuration of the first projector, the second projector and the third projector, and set the first charge-of-shoot region and the second charge-of-shoot region based on the camera layout, and
• computes geometric correction data and transmits the geometric correction data to the plurality of projectors.
