Abstract: A method and circuit for compensating variations induced by temperature, strain and manufacturing technology in CMOS video sensors. Using at least two reference CMOS sensors, held at the same temperature level as the CMOS video sensors to be compensated and which are not irradiated, two reference signals are generated whereof one corresponds to a reference dark value whilst the other one, in response to the application of an electric current, corresponds to a reference illumination value. The reference signals are amplified separately of each other. At least one correction value is stored in a memory unit for each CMOS video sensor point to be compensated, such that output signals corrected by FPN (=fixed pattern noise) will be obtained. The FPN-corrected output signals as well as the reference signals obtained are supplied to the A/D converter where the output signals of the CMOS video sensor are compensated and converted into digital signals.

Abstract: A method and a device for image processing and for a night vision system for motor vehicles, in which a standard camera that is sensitive in the near infrared delivers images which are displayed on a display arrangement having a lower resolution than the camera. In addition, the image processing method improves the raw images of the sensor using image-sharpening methods and/or contrast-enhancing methods, so that display on a display arrangement is made possible for viewing by a viewer.

Abstract: The invention relates to a MOS transistor for a photo cell, comprising a semiconductor substrate on which a gate electrode, a drain electrode and a photosensitive source region are configured. An oxide layer is arranged between the gate electrode and the substrate, and in the active region of the MOS transistor this oxide layer is formed as thin oxide film while it is configured as thick oxide film in a passive region. The inventive transistor is distinguished by the provisions that the gate electrode comprises a closed annular section in the active region of the MOS transistor, and that either the drain electrode or the photosensitive source region is arranged within the annular section of the gate electrode so that current will only flow in the active region.
