Abstract

In accordance with the invention a system is described for controllably varying the resolution of an image event to conserve data output by varying the size of the instantaneous IFOV of an array of detectors. The system comprises a multiplicity of individual detectors which produce an electrical signal in response to an image stimulus. The detectors are connected to busing circuitry by a circuit associated with each individual detector and which is in parallel with the circuits from the other detectors. Each parallel circuit includes a switch for making and breaking the parallel circuit to the busing circuit and control means are provided for opening and closing the switches in real time. As the switches are opened and closed the output signals of the detectors are combined into signals representing pixels having various size instantaneous fields of view depending on the number of detectors whose signals are combined. Combining detector output signals reduces the data output and conserves data processing capacity.
