ABSTRACT:
An imaging device and method for operating the device. The imaging device comprises a pixel array that comprises a plurality of imaging pixels and dark reference pixels arranged in columns and rows. The dark reference pixels produce a noise signal that is subtracted from a pixel signal produced by the imaging pixels to correct row noise. In addition, the imaging device may comprise a hot pixel filtering circuit that blocks the output from hot pixels.
