Abstract: An image display system according to the present disclosure includes a plurality of image output devices and a plurality of image display devices that are connected to one another via a network. When a predetermined image output device that is one of the plurality of image output devices and a predetermined image display device that is one of the plurality of image display devices are connected, the predetermined image output device transmits a pairing start image signal to the predetermined image display device. The predetermined image display device receives the pairing start image signal transmitted from the predetermined image output device.

Abstract: An image adjustment system 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.

Abstract: A projection image adjustment system includes: a pattern generator decomposes a projection test pattern into binary test patterns individually corresponding to first attributes to be expressed in a binary manner; a projection display apparatus projects a projection image and the binary test patterns; a pattern combining unit generates binary captured images by individually binarizing captured images generated by capturing the projected binary test patterns and combines the binary captured images into a combined captured image; and a calculator transforms the projection image by using a relationship between positions of feature points in the combined captured image and positions of the feature points in the projection test pattern. The projection test pattern includes divided regions, each of the regions includes a second attribute to be expressed by a combination of the first attributes, and each of the feature points is a point shared three or more adjacent regions among the regions.

Abstract: After calibration of the projector, the control circuit obtains a first position-data indicating the position of a feature point in the screen and a second position-data indicating the position of a feature point in a test image projected onto the screen. After acquisition of the first position-data and the second position-data, the control circuit obtains a third position-data indicating the position of a feature point in the screen and a fourth position-data indicating the position of a feature point in the test image projected onto the screen. Based on a difference between the first position-data and the third position-data, the control circuit corrects the position of a feature point in the test image contained in the fourth position-data to create a fifth position-data. Based on a difference between the second position-data and the fifth position-data, the control circuit recalibrates the projector.

Abstract: The projection image adjusting system has a storage, a receiving section, and a controller. The storage stores virtual-environment setting information on a set-up situation of a projection display apparatus set so as to have a desired image-projection state on an object on which an image is projected in a virtual space created by a computer and also stores a control set-up value for the projection display apparatus in the desired image-projection state. The receiving section receives real-environment setting information on a set-up situation of the projection display apparatus in a real space. The controller controls the projection display apparatus in the real space. Based on the virtual-environment setting information and the real-environment setting information, the controller corrects the control set-up value so as to decrease a difference between an image-projection state in the real space and the desired image-projection state.
