Imaging apparatus, imaging system and method thereof

摘要

To provide a system, apparatus and method of changing frame rate of cameras according to the detector that has sent an alarm signal, in order to optimize utilization of hardware resources. An apparatus for setting a frame rate under which images are captured by a camera in an image capturing system having a plurality of cameras and a plurality of detectors, the apparatus including: detector interface for receiving a first signal from at least one of the sensors; association unit for associating the first signal with information related to the camera; calculation unit for calculating a frame rate of each of the plurality of cameras based on the association between the first signal and the information related to the cameras; setting unit for setting the frame rate of the camera calculation by the calculation unit; and second reception unit (capture card) for receiving image data from the camera at a frame rate set by the setting unit.
