Abstract
Abstract The present invention relates to a device for the input and processing of information comprising sensor elements arranged in matrix form, which are integrally formed on a substrate. Each sensor element comprises output electronics ( 3 ) and at least one photovoltaic cell (PD), which is adapted to convert an optical signal incident upon the photovoltaic cell to an electrical signal. The device according to the invention is characterized in that each sensor element is adapted to perform compensation of an offset error in the output electronics ( 3 ) forming part of the sensor element and that each sensor element is adapted to perform the said offset compensation independently of the other sensor elements in the device.
