Projection image adjustment system and projection image adjustment method
View Patent ↗The projection image adjustment system includes: projection display apparatuses for projecting projection images; a first and a second imaging apparatus for shooting the projection images; and a controller. The controller includes: an imaging-apparatus selecting unit, a shooting-region setting unit, a pattern projection unit, and a shot-image display unit. The imaging-apparatus selecting unit selects the first or the second imaging apparatus. The shooting-region setting unit sets a first and a second charge-of-shoot region for a projection display apparatus. The first and the second imaging apparatus are respectively in charge of shooting the first and the second charge-of-shoot region. At least one projection display apparatus is shared by the first and second charge-of-shoot regions. The pattern projection unit projects a format pattern of the projection display apparatus corresponding to the first or the second charge-of-shoot region. The shot-image display unit displays an image of the first or the second imaging apparatus.

computes geometric correction data and transmits the geometric correction data to the plurality of projectors.
2. The projection image adjustment system according to claim 1 , wherein the controller is further configured to project a second format pattern different from the first format pattern by using at least one of the plurality of projectors adjacent to a projector that projects the first format pattern.
3. A method performed by a processor, the method of adjusting projection images projected on a projection screen by a plurality of projectors including a first projector, a second projector and a third projector, each of the first projector, the second projector and the third projector are distinct from each other, a projection image of the projection images being captured by a first camera to provide a first captured image, a projection image of the projection images being captured by a second camera to provide a second captured image, the second captured image includes at least a portion which is different from the first captured image, the projection images being adjusted based on the first or second captured images, the method comprising steps of: selecting one of the first camera and the second camera as a selected camera; setting 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 captured image and the second captured image, the second camera being in charge of shooting the second charge-of-shoot region including the second captured image and a third captured image, the third captured image based on an image projected by the third projector; projecting a first format pattern by using the plurality of projectors that project the first or second captured image captured by the selected camera; displaying an image captured by the selected camera, selecting 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 setting the first charge-of-shoot region and the second charge-of-shoot region based on the camera layout, and
computing geometric correction data and transmitting the geometric correction data to the plurality of projectors.
4. The method of adjusting the image according to claim 3 , wherein, in the step of projecting, a second format pattern different from the first format pattern is projected by at least one of the plurality of projectors adjacent to a projector that projects the first format pattern.
5. The projection image adjustment system according to claim 1 , wherein the plurality of second projection images further includes at least one image which is the same as the plurality of first projection images captured by the first camera.
6. The method of adjusting the image according to claim 3 , wherein the second captured image further includes at least a portion which is the same as the first captured image.
7. The projection image adjustment system according to claim 1 , wherein the controller is further configured to display a mark which represents a projection region of one of the first camera and the second camera indicating a set shoot region as a current charge-of-shoot region.
8. The method of adjusting the image according to claim 3 , wherein the method further comprising a step of displaying a mark which represents projection region of one of the first camera and the second camera indicating a set shoot region as a current charge-of-shoot region.
9. The projection image adjustment system according to claim 7 , wherein the controller is further configured to accept an instruction by a user for changing a position of the mark on the display unit.
10. The method of adjusting the image according to claim 8 , wherein the method further comprises a step of accepting an instruction by a user for changing a position of the mark.
