Patent attributes
An image display system according to the present invention includes a camera that shoots a background, a monitor that displays a shot background image, and an optical lens arranged on a display surface of the monitor. An imaginary image, obtained due to presence of the optical lens, of the monitor image is made to substantially match with a background surface, so that observers viewing the background through the monitor can recognize that the monitor image and the background look continuous. As a result, the image display system and the image display method that can cause the observers viewing the background through the monitor to recognize that the monitor image and the background look continuous are provided.
