Title:
CMOS撮像素子内での効率的な電荷転送
Document Type and Number:
Japanese Patent JP2009506724
Kind Code:
A
Abstract:
Methods for operating a pixel cell include efficient transferring of photo-charges using multiple pulses to a transistor transfer gate during a charge integration period for an associated photosensor. The pixel cell can be operated with efficient transfer characteristics in either normal or high dynamic range (HDR) mode. The high dynamic range can be realized by either operating an optional HDR transistor or by fluctuating the voltage applied to a reset gate.
