    • Camera control apparatus enabling a user to intuitively understand a photographing direction and zoom magnification of a camera at the time of switching over an image, and enabling camera control to be started immediately. At camera control apparatus (120), camera image switching section (121) switches over images of cameras instructed to be switched over to by a user. Zoom magnification control sections (124, 125, 126) acquire zoom magnification of a camera instructed to be switched over to, set zoom magnification of a camera before switching of the camera image switching section (121) to a reference magnification lower than the acquired zoom magnification, and change zoom magnification of the camera after switching from the reference magnification to the acquired zoom magnification. Image display section (122) then displays the image of the camera image switching section (121) has switched over to.

    • The present invention provides a video surveillance system which tracks a tracking target by a plurality of surveillance cameras. This system is capable of tracking completely the location of the tracking target even in case the camera picture is automatically changed in accordance with the moving of the tracking target. The system includes a moving direction detector for detecting the moving direction of a tracking target. Moreover, the system has storage units for storing the passage configuration of a surveillance zone and the camera location information. The system also has a camera selector for identifying a camera which will shoot the tracking target next in accordance with the moving direction information, passage configuration information and camera location information, and a screen composition unit for synthesizing on a screen a picture from a camera shooting the tracking target and a picture from a camera selected by the camera selector.
    • 本发明提供了一种通过多个监视摄像机跟踪跟踪目标的视频监控系统。 即使在根据跟踪目标的移动来自动改变照相机图像的情况下,该系统也能够完全跟踪跟踪目标的位置。 该系统包括用于检测跟踪目标的移动方向的移动方向检测器。 此外,该系统具有用于存储监视区域的通道配置的存储单元和摄像机位置信息。 系统还具有用于识别将根据移动方向信息,通道配置信息和照相机位置信息来拍摄跟踪目标的相机的相机选择器,以及用于在屏幕上合成来自相机拍摄的图片的屏幕合成单元 跟踪目标和由相机选择器选择的相机的照片。
