We propose a surveillance system that is capable of obtaining a wide-angle view as well as detailed views of multiple regions of interest simultaneously. Based on a CMOS imaging technology, a solid-state multicamera-array whose pixels can be read out at random is used. The camera array does not have any mechanicalmotion elements and quickly switches between a low-resolution output for wide-area-monitoring and high-resolution output for detailed-views of multiple moving objects. Thus, the size of the total transmission data from the cameraarray to the monitoring-site can be kept relatively small. The system continuously outputs a hardware-subsampled wide-angle view. If moving objects enter the field of vision, the system automatically tracks them and outputs detailed views of all objects in addition to the wide-angle view. We have developed an experimental sized surveillance system with 16 CMOS random access image sensors.
