Paul R N Kellar, Robin A Cawley, Neil R Hinson: Video signal processing systems. Quantel, Cooper & Dunham, September 27, 1988: US04774583 (116 worldwide citation)

A video signal processing system in which a number of video image signals are combined to provide an output which is such that where several objects of the input images overlay so they appear to be at different distances. Each input video signal is provided with a priority signal and a series of con ...

Richard J Taylor, Paul R N Kellar, Neil R Hinson: Video processing systems. Quantel, Cooper Dunham Clark Griffin & Moran, January 7, 1986: US04563703 (49 worldwide citation)

A processing system includes a processor 10 and frame store 11. Both the frame store and processor are under the control of address mechanism 12. The addressing mechanism 12 can generate the desired information from address information which is only provided on some of the store locations and which ...

A processing system for effecting angular displacement of at least part of a television picture. The picture is subdivided into picture areas each containing a plurality of picture points and a number of storage devices respectively receive information on each picture point within the area at a desi ...

Paul R N Kellar, Neil R Hinson, Alan L Stapleton: Method and apparatus for manipulating video image signals. Quantel, Cooper & Dunham, May 18, 1993: US05212544 (18 worldwide citation)

A system for manipulating video image signals, in which digitized composite video signals (i.e. D2 digitally encoded PAL or NTSC) are converted to component video signals (i.e. luminance and color difference signals) allowing selected pixels to be modified. In addition, the unconverted composite vid ...

Neil R Hinson, Stephen P Greenhalgh: Video signal processing with filtering to account for picture compression. Quantel, May 12, 1987: US04665433 (16 worldwide citation)

A video signal processing system which produces the same output image as the input image but with a size and/or shape change applied to it. The incoming video signals are written into the frame store in sequence but read out in an order determined by the output image required. When compressions in t ...

Robin A Cawley, Neil R Hinson, Robert Long, Alan L Stapleton: Video signal processing with added probabilistic dither. Quantel, Cooper & Dunham, April 4, 1995: US05404427 (15 worldwide citation)

A system in which a characteristic of individual picture points is provided to an accuracy of m binary bits but conveyed by n bits, where n is less than m. The value of a lower order bit of the n bit signal is switched to cause said binary value to represent, for any one picture point, either a valu ...

Neil R Hinson: Improvements in or relating to video image keying systems and methods. Quantel, Cooper & Dunham, June 27, 1995: US05428401 (10 worldwide citation)

An image processing system operates on first and second image data (V and Bg) to produce data defining a combined image. The first image data (V) represents a keyed image comprising a first object (F) keyed over a portion of a first background (B) in accordance with keying data (K). The second image ...

Richard J Taylor, Paul R N Kellar, Neil R Hinson: Video processing systems. Quantel, Cooper Dunham Griffin & Moran, November 24, 1987: US04709393 (10 worldwide citation)

A processing system includes a processor 10 and frame store 11. Both the frame store and processor are under the control of address mechanism 12. An incoming pixel is processed with previously stored information and the proportion of processed information restored is controlled to prevent errors in ...

Neil R Hinson: Video processing systems. Quantel, Cooper & Dunham, July 5, 1988: US04755879 (4 worldwide citation)

A video processing system is disclosed having a store (1) into which video signals, in the form of a sequence of pixels, are written into and read out of in response to common fixed clocking pulses, although the input video signal is synchronized independently of the output video signal. The phase o ...
