Patent ID: 8681254

Claim:
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, wherein said temporal order comprises a set of sequentially contiguous rows, wherein each row in said set belongs to a different physically contiguous block of rows located in said array and having a first number of rows, wherein each of said physically contiguous blocks of rows is bounded by a pair of rows that precede said set in said temporal order or by a row that precedes said set in said temporal order and one of an outer edge of a physical first row and a physical last row in said array.
