Abstract: The present invention provides a method and a system for high performance image signal processing of continuous images in real time. The system comprising a focal plane array for generating continuous source image frames in real time. The focal plane array divided logically into blocks of sub-frames. The system also comprising an analog to digital converter (ADC) layer having an array of ADC elements for converting the source image frames into a digital data. The system further comprising a digital processor layer having an array of processing elements for processing the digital data and an interconnecting layer for connecting each one of the ADC elements and the digital processing elements substantially vertically to the focal plane and substantially parallel to one another. The processing comprising reducing image motion blur, increasing image dynamic range, increasing image depth of field and obtaining features of the images.

Abstract: An optical sensor circuit for generating signals corresponding to received photoelectrons is formed on a single monolithic substrate and includes a charge coupled device (CCD) array. The array is formed of a plurality of pixels constructed by a standard CMOS process. Each pixel is formed of at least one charge well of minority carriers and a gate oxide layer overlaying the at least one charge well. At least two spaced gate electrodes corresponding in position to the at least two charge wells overlays the gate oxide layer. The space between adjacent electrodes defines a gap to transfer charge between adjacent ones of at the least two spaced gate electrodes and the gap is stabilized. A back-illuminated imager is also described in which photocarriers are diverted from devices integrated with the pixel by a PN junction formed in the pixel structure.

Abstract: A method and apparatus for resolving relative times-of-arrival of a plurality of light pulses includes a plurality of drift-field detectors. Each drift-field detector includes a light sensor and a semiconductor drift region. Each light sensor generates an electrical charge from at least one of the plurality of light pulses. Each semiconductor drift region receives the electrical charge from its respective light sensor and, pursuant to an electric field therein, produces a spatial charge distribution. The spatial charge distribution for each of the semiconductor drift regions is stored in an analog storage device associated therewith. The relative positions of the charge distributions in the semiconductor drift regions are used to calculate the relative times-of-arrival of the light pulses.

Abstract: A method and apparatus for low light imaging in which a plurality of relatively small detectors forming a line is coupled to a respective cell of a CCD register. A charge indicative of detected image information is provided to the respective cells after the cells are substantially discharged via a drain. The register is read by a control element to define therefrom a row of pixel information.
