  • METHOD FOR OPERATING AN ELECTRONIC IMAGING SYSTEM, AND ELECTRONICS IMAGING SYSTEM
    Publication number: 20060261256
    Abstract: The electronic imaging system includes a sensing device between a reset supply and a pixel array. While the pixels of the array are held in reset, the varying current supplied by the reset supply is monitored to provide information on scene changes.

  • Readout circuit
    Publication number: 20050285960
    Abstract: The readout circuit, for an image sensing pixel array, is arranged to perform correlated double sampling and includes readout circuitry which is capable of learning its own internal offset and the offset of both its inputs. In the process of correlated double sampling, one of two sampling capacitors can be made smaller, as the thermal noise it creates is learned. The reduction of size of the appropriate sampling capacitor enables the size of a column multiplexer to be reduced without affecting its noise contribution.
