画像キャッシングを用いた仮想視野移動操作の遅れ感覚軽減法

抄録

In this paper, the authors propose the operational time lag reduction method that is caused by remotely movable cameras whose pan, tilt and zoom parameters can be controlled. It temporarily caches the image data that is sent from the movable cameras being able to operated from remote PCs. This is achieved by cutting out and presenting of the cached images until the result of the operation from remote PC is reflected on the CRT. The authors applies simplified spherical mapping for correction of image distortion that is caused by cutting out. It plans securing of the real time and the reduction of sense of incongruity of remote operation.
