This abstract first appeared for US patent application 18239546 titled 'IMAGE DISPLAY SYSTEM, TERMINAL, METHOD, AND PROGRAM FOR DETERMINING A DIFFERENCE BETWEEN A FIRST IMAGE AND A SECOND IMAGE

==Simplified Explanation==

The present invention is an image display system that aims to quickly and accurately display an image corresponding to a specific location. It includes a mobile terminal that captures images, acquires information about the position and orientation of the terminal, and retrieves past images stored in a storage device based on their associated position and orientation. The system also includes a difference detection unit to identify any differences between the current and past images.

* The system acquires a first image captured by a mobile terminal.
* It retrieves information about the position and orientation of the terminal.
* It retrieves a second image from storage based on the position and orientation of the terminal and the associated position and orientation of the second image.
* It detects any differences between the first and second images.

Potential applications of this technology:

* Augmented reality applications that overlay images onto real-world locations.
* Navigation systems that provide visual cues based on past images of a location.
* Virtual tours or historical reconstructions that show how a location has changed over time.

Problems solved by this technology:

* Quick and accurate display of images corresponding to specific locations.
* Efficient retrieval of past images based on their associated position and orientation.
* Detection of differences between current and past images.

Benefits of this technology:

* Enhanced user experience by providing relevant and accurate visual information.
* Improved navigation and orientation in unfamiliar environments.
* Efficient comparison and analysis of changes in a location over time.


==Original Abstract Submitted==

The present invention provides an image display system, a terminal, a method, and a program that can quickly and accurately display an image corresponding to a particular location. An image display system according to one example embodiment of the present invention includes: a current image acquisition unit configured to acquire a first image captured by a mobile terminal; an information acquisition unit configured to acquire information including a position and an orientation of the mobile terminal that has captured the first image; a past image acquisition unit configured to acquire a second image based on the position and the orientation of the mobile terminal and a position and an orientation associated with the second image stored in the past in a storage device; and a difference detection unit configured to detect a difference between the first image and the second image.
