Abstract This paper will discuss a method for presenting a surveillance image captured by an active camera such as one that actively tracks a moving subject as an image that is easily understood by an observer. Active camera surveillance images generally have a narrow field of view, and changes in the line‐of‐sight direction of an automatic camera make it difficult for an observer to intuitively understand the scene. However, enhancement of the observer's ability to comprehend the scene can be anticipated by adding a wide‐angle panoramic image to the periphery of the narrow‐field observed image and presenting it as an image that has a wider field of view. In order for an observer to understand conditions in a remote location, the observed image and the panoramic image must be integrated with geometric/photometric consistency. The present paper will discuss a method of geometric integration using a fixed‐viewpoint camera, and a method of photometric integration by modeling of brightness variation by eigenimage analysis. © 2006 Wiley Periodicals, Inc.
