Abstract: A method of processing low resolution input frames containing undersampled views of an optically imaged scene to produce a higher quality, higher resolution output frame. This method operates by obtaining a sequence of low resolution input frames containing different undersampled views of an optically imaged scene.

Abstract: An optical/electronic real time image motion transfer system is disclosed in which voltage output signals from photodetectors in an array are fed through a switching network. This network includes intermediate buses, electronic switching devices between such buses and addresses of the signals from the photodetectors, and electronic switching devices between such buses and addresses of the signals which are fed to the output lines. The output lines preferably receive their multiplexed signals from filters, or bins, which have stored (and thus integrated) successive voltage signals from individual pixels.

Abstract: A focal plane electronic system is disclosed, in which a two-dimensional array of photo-detectors receives pixel information from a scanned scene. Each pixel is observed by a plurality of detectors, and their signals are summed by time delay and integration (TDI) circuitry. The TDI circuitry comprises parallel capacitors which are charged and discharged under the control MOSFET switches. The discharge timing is such that all the detector signals representing a given pixel arrive simultaneously at a summing node. Means are included for automatically reducing the effect of anomalous detector signals on the summed output. The entire TDI system is included in a Z-type three-dimensional focal plane module.
