PURPOSE: A pixel cell, active pixel sensor(ASP), and method for operating the same are provided to reduce, eliminate artifacts in resultant images, and achieve a consistent reset level for substantially all pixels. CONSTITUTION: The APS includes an active pixel array(22) with a plurality of pixels(30,40), one at each row and column intersection, control logic(24), row decode logic(26) and column output processing logic(28). Control logic(24) produces row select and reset signals. Column output processing logic(28) includes column amplifiers, a row buffer and other known circuitry for processing array output signals.
