Abstract:
1. A digital surveillance camera comprising: an image sensor configured to generate an image data raw stream; a memory configured to store image data generated in response to receiving the image data raw stream; a data input device configured to receive predetermination information including a plurality of image parameter sets, each of the plurality of image parameter sets being independent from each other and including pan tilt and zoom parameters so that each of the plurality of image parameter sets designates image segments or image details relating to a different image; a determination unit configured to determine, in response to receiving the plurality of image parameter sets, a maximum block to be read out from the image sensor for the generation of the image data raw stream so that other image data that is registered with the image sensor and that does not lie in the maximum block is not read out from the image sensor, the maximum block being determined by two independent image parameter sets; and a data output device configured to output the image data, which is generated in response to receiving the image data raw stream, to the memory, and to simultaneously output the image data at two different resolutions, the two different resolutions including a first resolution, which is a relatively higher resolution and a second resolution, which is a relatively lower resolution, wherein first image data of the first resolution is output to a user connected to the digital surveillance camera via a bandwidth-limited connection, wherein second image data of the second resolution has a frame rate sufficiently high to avoid jerky reproduction or to compensate for expected movement in order to avoid fatigue phenomena during observation, and wherein the first image data of the first resolution has a relatively lower frame rate and is based on the image data stored in the memory, the first image data of the first resolution being transmitted from the memory to the user in response to a request from the user after transmission of compressed image data from the memory.
