Publication number: 20050206758Abstract: A conventional image sensing device allowed significant amounts of unwanted electrons to flow upon pixel mixture, thereby providing a low transfer efficiency. An image sensing device has an image sensing section in which multiple light-receiving pixels for converting incident light into information charge for storage during an image sensing period are disposed in rows and columns in a light-receiving region on a semiconductor substrate. A storage section temporarily stores information charge that has been vertically transferred from the image sensing section. A horizontal transfer section vertically transfers row by row the information charges accumulated in the storage section. A driving section provides vertical transfer control.Type: ApplicationFiled: March 9, 2005Publication date: September 22, 2005Inventors: Takayuki Kaida, Masahiro Oda
