    摘要: A circuitry for high-speed reading of a video cell for a video pickup chip including a plurality of such video cells disposed in the form of a two-dimensional array, and a read-out logic designed for imaging a high input signal dynamic volume onto a reduced output signal dynamic volume, wherein the photosensitive element of the video cell is connected to the first main electrode of a first MOS transistor (M0) and to the gate of a second MOS transistor (M1) such that the gate and the other main electrode of the first MOS transistor (M0) are short-circuited and applied to an invariable potential (Vpp) so as to achieve a logarithmic characteristic line, and that an output signal amplifier is connected to the second main electrode of the second MOS transistor (M1). Moreover, a method of high speed reading of this video cell is described. The invention excels itself by the provision that a further MOS transistor (Mr1) of the same charge carrier type, which is connected in parallel with the first MOS transistor (M0), is provided and has a main electrode short-circuited to the first main electrode of the first MOS transistor (M0), and that a reset voltage pulse is applicable to the gate electrode of this further MOS transistor (Mr1).

    摘要: In order to correct for fixed pattern noise in the signals of an image sensor, image signal values are read out from the pixels of the sensor. Individual correction values are added as analogue quantities to the image signal values via a signal path having a defined transfer function. Parameters which are characteristic of the defined transfer function are provided in a memory and the individual correction values are calculated in a correction value calculating unit using the parameters provided.
