Pixel reading electronic device in particular for matrix image sensor with active cmos pixels

摘要

The invention concerns an electronic device for reading pixels of a matrix image sensor, in particular for a sensor with active CMOS-type pixels, said sensor comprising N lines and M columns of active pixels (1). The invention is characterised in that it comprises signal acquisition means, adapted to send directly, for each pixel (1) of each column, on an output bus (18) a signal representing the potential difference between a reference signal Vref and a light level signal Vsig of said pixel (1).
