Patent ID: 7180544

Claim:
A solid state image sensor comprising a plurality of amplifying unit pixels arranged two-dimensionally on a semiconductor substrate, each of said plurality of amplifying unit pixels including a photoelectric conversion region for subjecting incident light to photoelectric conversion; a read transistor for reading signal charge obtained through the photoelectric conversion; a storage region for storing said signal charge read by said read transistor; a detect transistor for detecting said signal charge on the basis of application of potential of said storage region to a gate thereof; a reset transistor for resetting said signal charge stored in said storage region; and a drain region for supplying a pulse voltage to said storage region through said reset transistor, wherein said drain regions of said plurality of amplifying unit pixels are connected to different drain lines row by row, and said drain line is pulse driven to be set to a HIGH level potential at least during a period when said signal charge stored in said storage region is reset and a period when said signal charge stored in said storage region is detected, and wherein not less than two drain lines are set to a HIGH level potential during one blanking period for detecting signal charges of not less than two pixels adjacent to each other in a column direction out of said plurality of amplifying unit pixels.
