MULTI-CAMERA PROGRAMMABLE PAN-AND-TILT APPARATUS

摘要

A multi-camera programmable pan-and-tilt apparatus (fig.1) comprising a base (22) and a camera mechanism (24) having a first camera (26) and a second camera (30), that includes a zoom mechanism (34) for varying the zoom magnification of the second camera (30). The apparatus (fig.1) further comprises a pan-and-tilt mechanism (40) for moving the cameras with respect to the base, and a video switch (48) for receiving the video outputs of the cameras (44, 46) and selecting one for view. The first camera (26) is viewed for moving scene and the second camera (30) is non-movable and is paused for observation of a scene. The apparatus further comprises a programmable controller (50), which controls the camera mechanism (24) the pan-and-tilt mechanism (40), and, predetermined zoom and focus variations of the second camera. The second camera (30) may be equipped with a motion sensor (36) and a microphone for picking up motion noise. The result of the motion sensor causes intermittent pause of the camera mechanism (24) for additional viewing of the scene and for alerting an operator.
