Abstract
This invention is to provide a solid-state image pickup element including a sensor unit including a plurality of lines of photoelectric conversion units for generating charges from received light by photoelectric conversion, a memory unit including a plurality of lines of storage units for storing signals from the plurality of lines of photoelectric conversion units, a transfer unit for transferring a signal from the sensor unit to the memory unit, a control unit for causing storage units of an arbitrary block in the memory unit to output an image signal from the photoelectric conversion units and causing the photoelectric conversion units corresponding to the storage units of the arbitrary block to output a noise signal, and a subtracting unit for calculating a difference between the image signal and the noise signal.
