Patent ID: 7187410

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 a read pulse for said read transistor of a first pixel out of said plurality of amplifying unit pixels and a reset pulse for said reset transistor of a second pixel adjacent to said first pixel in a column direction are supplied through a common gate line, a LOW level potential of said drain region of said first pixel is set, in resetting said second pixel, to a potential higher than a potential depth of said photoelectric conversion region of said first pixel.
