METHOD, APPARATUS AND SYSTEM PROVIDING SUPPRESSION OF NOISE IN A DIGITAL IMAGER

摘要

Method, apparatus and systems are disclosed in which a digital imager has optically black reference pixels in at least one row of a pixel array. The signals from the reference pixels in one row of the array are used as reference signals to cancel out the row-wise noise from pixel signals readout from active pixels in other rows of the array. An arrangement for locating the array driving circuit relative to the reference pixels is also provided.
