Abstract

A projection method including: when executing a first adjustment including correction of a shape of a first projection image to be projected by a projector, updating a first setting value for correcting the shape of the first projection image by receiving an operation of changing the shape of the first projection image; and projecting, from the projector, a third projection image in which the shape of the first projection image is corrected based on the first setting value and a luminance of an overlapping area in the first projection image is not corrected, the overlapping area being an area where a second projection image projected by another projector different from the projector and the first projection image overlap with each other.

Claims (28)

1 . A projection method comprising:

when executing a first adjustment including correction of a shape of a first projection image to be projected by a projector,

updating a first setting value for correcting the shape of the first projection image by receiving an operation of changing the shape of the first projection image; and

projecting, from the projector, a third projection image in which the shape of the first projection image is corrected based on the first setting value and a luminance of an overlapping area in the first projection image is not corrected, the overlapping area being an area where a second projection image projected by another projector different from the projector and the first projection image overlap with each other, and

in a case where an operation of ending the first adjustment is received when executing the first adjustment,

changing a projection image to be projected from the projector from the third projection image to a fourth projection image obtained by correcting the luminance and the shape of the first projection image based on the first setting value and a second setting value for correcting the luminance.

2 . The projection method according to claim 1 , wherein

the first adjustment indicates an adjustment of the first projection image according to an operation received from a user.

3 . The projection method according to claim 1 , wherein

the receiving an operation of changing the shape of the first projection image includes receiving a change in a position of a contour indicating the shape of the first projection image or a change in a position of a vertex of the first projection image.

4 . The projection method according to claim 3 , wherein

the receiving a change in the position of the contour or the position of the vertex includes receiving a drag-and-drop operation for moving the position of the contour or the position of the vertex.

5 . The projection method according to claim 4 , wherein

the first adjustment indicates an adjustment of executing correction of the shape of the first projection image by receiving a drag operation of moving the position of the contour or the position of the vertex.

6 . A processing device comprising:

one or more processors configured to

when executing a first adjustment including correction of a shape of a first projection image to be projected by a projector,

update a first setting value for correcting the shape of the first projection image by receiving an operation of changing the shape of the first projection image, and

cause the projector to project a third projection image in which the shape of the first projection image is corrected based on the first setting value and a luminance of an overlapping area in the first projection image is not corrected, the overlapping area being an area where a second projection image projected by another projector different from the projector and the first projection image overlap with each other; and

in a case where an operation of ending the first adjustment is received when executing the first adjustment,

change a projection image to be projected from the projector from the third projection image to a fourth projection image obtained by correcting the luminance and the shape of the first projection image based on the first setting value and a second setting value for correcting the luminance.

7 . A non-transitory computer-readable storage medium storing a program, the program comprising:

causing one or more processors to

when executing a first adjustment including correction of a shape of a first projection image to be projected by a projector,

update a first setting value for correcting the shape of the first projection image by receiving an operation of changing the shape of the first projection image, and

cause the projector to project a third projection image in which the shape of the first projection image is corrected based on the first setting value and a luminance of an overlapping area in the first projection image is not corrected, the overlapping area being an area where a second projection image projected by another projector different from the projector and the first projection image overlap with each other; and

in a case where an operation of ending the first adjustment is received when executing the first adjustment,

change a projection image to be projected from the projector from the third projection image to a fourth projection image obtained by correcting the luminance and the shape of the first projection image based on the first setting value and a second setting value for correcting the luminance.
