Control method for image projection system and image projection system

An image projection system including a first projector group and a second projector group,

• a range of images projected by the first projector group and a range of images projected by the second projector group being set to coincide with each other,
• the image projection system comprising one or more processors programmed for:
• displaying a first setting screen including a first region for setting positions of images projected by a respective plurality of projectors included in the first projector group and a second region for setting positions of images projected by a respective plurality of projectors included in the second projector group,
• receiving operation by a user on the first setting screen and set the positions of the images projected by the respective plurality of projectors included in the first projector group and the positions of the images projected by the respective plurality of projectors included in the second projector group,
• including with the first setting screen a first display region for displaying identification information indicating a respective communicably coupled plurality of projectors, and
• receiving operation by the user on the first display region and selecting, from the plurality of projectors displayed in the first display region, the respective plurality of projectors included in the first projector group and the respective plurality of projectors included in the second projector group.

A control method for an image projection system including a first projector group and a second projector group,

• images projected by the first projector group form a first layer of an image by tiling projection by a plurality of first projectors included in the first projector group,
• images projected by the second projector group form a second layer of the image by tiling projection by a plurality of second projectors included in the second projector group, and
• the first layer of the image and the second layer of the image are overlapped to coincide with each other by stacking projection by the first projector group and the second projector group,
• the control method for the image projection system comprising:
• displaying a first setting screen including
• a first region for setting positions of images projected by the respective plurality of first projectors, and
• a second region for setting positions of images projected by the respective plurality of second projectors;
• receiving operation by a user on the first setting screen;
• and
• setting the positions of the images projected by the respective plurality of first projectors and the positions of the images projected by the respective plurality of second projector.
