  • Image sensor
    Patent number: 8582010
    Abstract: The invention relates to an image sensor, in particular to a CMOS image sensor, for digital cameras, having a plurality of pixels arranged in rows and columns, wherein the respective pixel comprises: a light sensitive detector element to generate electrical charge from incident light during an exposure procedure, a readout node, a transfer gate to which a transfer control pulse can be applied to allow a charge transfer from the detector element to the readout node, and a reset device to reset a charge present in the readout node to a reference value. The image sensor furthermore has a control device for the control of the transfer gate and of the of the reset device of the respective pixel.

  • Image recording system and method of calibrating, compressing and decompressing image signal values
    Patent number: 8248477
    Abstract: A method of calibrating, compressing and decompressing image signal values of an image sensor which has a plurality of light sensitive pixels arranged in rows and columns comprises the steps of: reading out the image signal values; compressing the image signal values; and decompressing the compressed image signal values, wherein the image signal values are calibrated while using calibration data sets which include a number of calibration values for each pixel.
