<P>PROBLEM TO BE SOLVED: To provide a solid state image pickup device capable of reducing the influence of noise due to leakage of a signal charge to a charge holding unit. <P>SOLUTION: A photoelectric conversion unit PD forms a signal charge based on incident light, where a global shutter operation exposes all pixels in a predetermined region at the same time. A charge holding unit FD holds the signal charge formed in the photoelectric conversion unit PD. A transfer transistor Mt transfers the signal charge from the photoelectric conversion unit PD to the charge holding unit FD. A correction dummy DM holds a noise charge generated corresponding to light quantity incident on the photoelectric conversion unit PD. An amplifier transistor Ma amplifies a signal based on the signal charge held by the charge holding unit FD and outputs the signal as an optical signal, and amplifies a signal based on the noise charge held by the correction dummy DM and outputs the signal as a noise signal. The optical signal and the noise signal are used to perform an operation for removing the noise signal from the optical signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
