Abstract:
1. Surveillance system, comprising: an image recording means for recording: moving, optically distorted, digital, wide angle images comprising a plurality of pixels, a transmission means for transmitting image information from the image recording means to a reproduction means, said reproduction means reproducing the optically distorted images in a manner correcting distortion, the transmission means comprising: the transmission means further comprising means for repeated transmission of geometrical distortion correction information and being adapted to receive a pan, tilt, zoom target parameter, to determine at least one region of interest according to the pan, tilt parameters; and to combine pixels depending on the zoom parameter; the transmission means being further adapted to provide an image stream based on the at least one region of interest for a differentially compressed transmission and to transmit the image stream together with an additional information allowing for geometrical distortion correction of the at least one region of interest to the reproduction means, so as to allow a distortion correction of the at least one region of interest in the reproduction means using a geometrical distortion correction and the additional information.
