## Abstract

A display control method includes displaying, by a projection device, a first user interface related to an adjustment of a projection image, displaying, by a control device communicating with the projection device, a second user interface including a display object corresponding to the projection image, transmitting, by the projection device, first adjustment information based on a first operation to the first user interface to the control device when the projection device accepts the first operation, adjusting, by the projection device, the projection image based on the first adjustment information, updating, by the control device, the display object based on the first adjustment information, transmitting, by the control device, second adjustment information based on a second operation to the second user interface to the projection device when the control device accepts the second operation, adjusting, by the projection device, the projection image based on the second adjustment information, and updating, by the projection device, the first user interface based on the second adjustment information.

## Claims

### Claim 1

A display control method comprising:
displaying, by at least one projector, a first user interface related to an adjustment of a projection image including a first display object corresponding to the projection image;
displaying, by at least one controller communicating with the at least one projector, a second user interface including a second user interface display object corresponding to the projection image;
transmitting, by the at least one projector, first adjustment information based on a first operation to the first user interface to the at least one controller when the at least one projector accepts the first operation;
adjusting, by the at least one projector, the projection image based on the first adjustment information;
updating, by the at least one controller, the first display object based on the first adjustment information;
transmitting, by the at least one controller, second adjustment information based on a second operation to the second user interface to the at least one projector when the at least one controller accepts the second operation;
adjusting, by the at least one projector, the projection image based on the second adjustment information; and
updating, by the at least one projector, the first user interface based on the second adjustment information, wherein
the adjustment of the projection image is a lens shift adjustment,
the first user interface represents a positional relationship between the projection image and an area in which it is possible to move the projection image with the lens shift adjustment, and
the first user interface includes a second display object representing a positional relationship between the area and the projection image, with the second display object superimposed on the first display object.

### Claim 2 (depends on 1)

The display control method according to claim 1, wherein
the displaying the first user interface includes displaying, by the at least one projector, the first user interface when the at least one controller accepts an instruction of starting the adjustment of the projection image; and
the displaying the second user interface includes displaying, by the at least one controller, the second user interface when the at least one controller accepts the instruction.

### Claim 3 (depends on 1)

The display control method according to claim 1, wherein
the displaying the second user interface includes displaying, by the at least one controller, the second user interface when the at least one projector accepts an instruction of starting the adjustment of the projection image; and
the displaying the first user interface includes displaying, by the at least one projector, the first user interface when the at least one projector accepts the instruction.

### Claim 4 (depends on 1)

The display control method according to claim 1, further comprising:
updating, by the at least one projector, the first user interface based on the first operation; and
updating, by the at least one controller, the second display object based on the second operation.

### Claim 5

A display system comprising:
at least one projector comprising at least one first processor; and
at least one controller comprising at least one second processor which communicates with the first processor, wherein
the first processor is programmed to execute
displaying a first user interface related to an adjustment of a projection image including a first display object corresponding to the projection image,
transmitting first adjustment information based on a first operation to the first user interface to the second processor when the first processor accepts the first operation,
adjusting the projection image based on the first adjustment information,
adjusting the projection image based on second adjustment information, and
updating the first user interface based on the second adjustment information, and
the second processor is programmed to execute
displaying a second user interface including a second user interface display object corresponding to the projection image,
updating the display object based on the first adjustment information, and
transmitting the second adjustment information based on a second operation to the second user interface to the first processor when the second processor accepts the second operation, wherein
the adjustment of the projection image is a lens shift adjustment,
the first user interface represents a positional relationship between the projection image and an area in which it is possible to move the projection image with the lens shift adjustment, and
the first user interface includes a second display object representing a positional relationship between the area and the projection image, with the second display object superimposed on the first display object.

### Claim 6 (depends on 5)

The display system according to claim 5, wherein
the displaying the first user interface includes displaying, by the at least one projector, the first user interface when the at least one controller accepts an instruction of starting the adjustment of the projection image; and
the displaying the second user interface includes displaying, by the at least one controller, the second user interface when the at least one controller accepts the instruction.

### Claim 7 (depends on 5)

The display system according to claim 5, wherein
the displaying the second user interface includes displaying, by the at least one controller, the second user interface when the at least one projector accepts an instruction of starting the adjustment of the projection image; and
the displaying the first user interface includes displaying, by the at least one projector, the first user interface when the at least one projector accepts the instruction.

### Claim 8 (depends on 5)

The display system according to claim 5, wherein:
the first processor is programmed to execute updating the first user interface based on the first operation; and
the second processor is programmed to execute updating the second display object based on the second operation.
