BACKGROUND

1. Technical Field

The present disclosure relates to an image adjustment system and an image adjustment device.

2. Description of the Related Art

The projector disclosed in Patent Literature 1 detects the angle at which an image should be rotated or tilted, and rotates the image at the detected angle while maintaining the aspect ratio of the image signal, thereby projecting the image on a screen.

Patent Literature 1 is Japanese Unexamined Patent Application Publication No. 2010-170048.

SUMMARY

Patent Literature 1 is susceptible to improvement in the workability of image adjustment when a plurality of image projection devices are used together.

In view of the above, an object of the present disclosure is to provide an image adjustment system and an image adjustment device with improved workability of image adjustment when the system or the device includes a plurality of image projection devices.

The image adjustment system according to the present disclosure includes: a plurality of image projection devices that respectively project a plurality of images in a plurality of projection ranges; an imaging device that captures a region containing the plurality of projection ranges to obtain a captured image; and a controller that controls the plurality of image projection devices and the imaging device. The controller calculates first rotation information representing an orientation of each of the plurality of images with respect to a first reference orientation of the captured image and adjusts display of each of the plurality of images based on the first rotation information to cause the orientation and the first reference orientation to be in a predetermined relation with each other.

The image adjustment device according to the present disclosure is a device for adjusting display of each of a plurality of images respectively projected in a plurality of projection ranges by a plurality of image projection devices. The image adjustment device includes: a calculation unit that calculates first rotation information representing an orientation of each of the plurality of images with respect to a first reference orientation in a captured image, the captured image being obtained by an imaging device when the imaging device captures a region containing the plurality of projection ranges; and an image adjustment unit that adjusts, based on the first rotation information, the display of each of the plurality of images to cause the orientation and the first reference orientation to be in a predetermined relation with each other.

The present disclosure provides an image adjustment system and an image adjustment device with improved workability of image adjustment when the system or the device includes a plurality of image projection devices.
