Paper Abstract

With regard to the intuitive monitoring system, it is important to support the smooth switching between a broad observation mode and a detail observation mode. We propose, in this paper, the 'Scope Cache', a device for elimination of the time lag between camera operation and indicated images, and for presenting with images without any critical delay as if the eyes and head motion of human being do so. This method is realized by caching the wider range of image sent from the remote-controlled movable camera with gaining a view by rapidly cutting out a certain portion of image from the entire image. Some experiments and examination of the system have been performed to show the effectiveness of the proposed method. The proposed method, which estimates the camera position considering the object in the picture from the camera, can be applied for any type of the fixed position pan-tilt camera.
