Surveillance camera apparatus and surveillance camera system
ActiveUS20100265331A1Easy to controlLarge and more clearlyTelevision system detailsColor television detailsOptical axisSurveillance camera
A wide-angle camera is fixed to direct an optical axis in a fixed direction. A telephotographic camera can be inclined in panning and tilting directions to change an aiming direction of its optical axis. An image signal from the wide-angle camera is evaluated. When an image of a moving object is identified in a frame captured by the wide-angle camera, directivity information corresponding to a position of the moving object is calculated based on a relative position to the center of the frame. In accordance with the directivity information, posture of the telephotographic camera is controlled to aim its optical axis at the moving object. Thereafter, the posture of the telephotographic camera is controlled continuously to place the image of the moving object in the center of the frame captured by the telephotographic camera. The telephotographic camera captures the moving object while tracking it.
