摘要:
A system and method for monitoring moving objects in a video system. The system includes at least one video camera; and at least one motion detector. The motion detector may include a lens having a field of view fixedly directed to an area of interest, and an imager for receiving an image through the lens and converting the image to video data. The motion detector may be configured to monitor the video data for movement of an object in the field of view and provide a detector output in response to the movement of the object. The detector output may be configured to cause adjustment of at least one operating characteristic of the video camera to target the camera on the object. A motion detector and methods of monitoring a multiplicity of moving objects are also provided.

A camera control system is arranged to improve operability of at least a camera or each of a plurality of cameras for panning and tilting control over the camera by permitting simultaneous confirmation of the photo-taking postures of the camera in the direction of tilting as well as in the direction of panning. The operability is improved by arranging a tilt control panel to be displayed to permit control in the tilting direction of the camera when a camera icon indicative of the camera is selected on a map displayed at a monitor.

A traffic control system selectively interfaces members of plural groups, as buyer groups and vendor groups, for video communication through a dial-up telephone system, for analyzing and compiling data, scheduling appointments, implementing conferences, consummating sales and the like. The traffic-control system comprises a telephonic interface apparatus for interfacing remote telephonic terminals of the dial-up telephone system identified with the members of plural groups, a video recording unit for recording and playing video transcriptions, a storage memory for storing data on the members, including telephonic terminal numbers and area-of-interest codes and a control computer to selectively interconnect the video recording unit with the remote telephone terminals through the telephonic interface apparatus to record and receive video communication.
摘要:
A system for achieving perspective-corrected views at a location removed from the site of the creation of a distorted wide angle image without the transmission of control signals to the site of image creation. Angles of tilt, pan and rotation, as well as degrees of magnification, are achieved without the use of mechanical devices by using transform algorithms. The system provides for the transmission of signals related to an uncorrected image from a site where this distorted image is created, with the transmitted signals being received at one or more processing sites for creating the perspectively-corrected views. Transmission can be via telephone lines, with the system including signal compression and decompression units. Wireless transmission is also utilized where desired.

Herein disclosed is a surveillance camera apparatus, comprising: a housing assembly having a slanted plate portion with an inner surface; and a camera assembly accommodated in said housing assembly, said slanted plate portion forming part of said housing assembly defining an opening therein, said opening having a central axis thereof, said opening having an imaginary inner surface flush with said inner surface of said slanted plate portion forming part of said housing assembly, and said imaginary inner surface of said opening having the shape of a circle, said camera assembly, including: a stationary member; a pan shaft having a pan axis thereof, said pan shaft being supported by said stationary member to be revolvable around said pan axis; a retaining member integrally formed with said pan shaft; a tilt shaft having a tilt axis thereof, said tilt shaft being retained by said retaining member to be revolvable around said tilt axis under the state that said tilt axis of said tilt shaft is in perpendicular relationship with said pan axis of said pan shaft; an imaging unit for taking an image of a specific object through said opening of said slanted plate portion forming part of said housing assembly, said imaging unit having a light axis thereof, said imaging unit being integrally supported by said tilt shaft under the state that said light axis of said imaging unit is in perpendicular relationship with said tilt axis of said tilt shaft; a pan motor for having said pan shaft driven around said pan axis; and a controlling unit for controlling said pan motor to have said pan motor move said imaging unit around said pan axis of said pan shaft in response to the revolution of said tilt shaft to be driven around said tilt axis.
摘要:
An intruder monitoring apparatus has at least a feature of correcting characteristic quantities by which an object to be monitored is specified, on the basis reference characteristic, when any change occurs in conditions of the video devices and environments. A further feature is provided which a plurality of scenes are monitored periodically by one camera and an image analysis function is driven so as to monitor any intruder only when the camera unit is fixedly directed to a specific scene among the scenes.
摘要:
A method and apparatus for the elimination of temporal and spacial distortions from interlaced video signals, particularly those that occur in signals associated with affine transformations. This elimination is particularly of value for signals that have been magnified so as to prevent the visual appearance of reverse movement of moving images. The removal of these distortions is achieved by sequentially inputting the images fields into three field buffers, updating the data in a rotary manner. This data is withdrawn from any two of the field buffers, while the third field buffer is being updated, and averaging the data from the two. When such averaged data is displayed, there is no apparent reverse direction motion to the image. The method and apparatus are applied to a system wherein there is affine transformation to achieve selected pan, tilt, rotation and magnification of images during the correction of distorted images received from a wide angle lens.

A video surveillance system includes a plurality of remote surveillance units, each of which has a video camera mounted in a dome housing. The video camera is panned and/or tilted to a desired orientation within the dome by a pan motor and/or a tilt motor. The surveillance system also includes a keyboard for entering user commands, a joystick for controlling the positioning of the cameras, a central processing unit for interpreting the user commands and the joystick movements, and a communication system for issuing operating commands to the remote surveillance units. Each remote surveillance unit is constructed and arranged to store and to recall selected camera control parameters in association with selected pan and tilt coordinates in response to commands entered by the user. The camera control parameters include white balance, focus, and shutter speed settings for the camera. Additionally, automatic control of the camera exposure, white balance, and focus is provided. Video signals from the remote surveillance units are received by a video switcher/multiplexer under the control of a central processing unit. The video switcher/multiplexer includes an automatic phase adjustment system for synchronizing the video signals from the remote surveillance units.

A video monitoring system responds to an intrusion alarm by automatically presenting still video images of the zone of the alarm at or about the time of the alarm. The operator can control magnification and contrast to enhance the displayed image. In one system the displayed images are images taken at times both before and after the alarm was received by the monitoring system.
