1. A method of operating an array of pixel sensor cells comprising: simultaneously exposing an entirety of an array of pixel sensor cells, wherein each of said pixel sensor cells contains a light conversion unit and a floating drain; simultaneously transferring electrical charges from said light conversion unit to said floating drain in each of said array of pixel sensor cells; and sensing said electrical charges in said floating drains one row at a time and for each row in said array, wherein a temporal order of row sensing contains a sequence of rows in which at least one pair of sequentially neighboring rows is physically non-neighboring.
