VIDEO SURVEILLANCE SYSTEM USING CAMERA CONTROL PARAMETERS TO OPTIMIZE MOTION VECTOR PROCESSING

摘要

A video camera apparatus (1) and a video surveillance system having a videocamera are provided with a video compression unit(50) which utilizes quantization for spatial processing and motion vectors fortemporal processing. The camera apparatus and surveillancesystem include a camera (10) with an adjustment mechanism (18) which allowspanning, tilting, zooming and focusing of the camera.The adjustment mechanism has a device for generating adjustment indicationsignals which indicate the state of adjustment of the camera.The adjustment indication signals are generated by a remote control panel orby means of transducers which detect the state of panning,tilting, zooming or focusing. Spatial or temporal processing are traded off,depending on whether the adjustment indication signals indicatemovement of the camera or zooming or focusing of the lens. Compressed videosignals are received by a monitoring station (220) fordecompression and display.
