Imaging element suitable for readout charges in plural times in a time dividing manner in one horizontal scanning period

An imaging clement that performs a processing with respect to a predetermined line of a plurality of photoelectric conversion elements in plural times in a time dividing manner in each horizontal scanning period, includes a photoelectric conversion unit; an address generating unit that generates an address indicating a position of the line of an object for each of a plurality of divided periods formed by time-dividing the each horizontal scanning period; an address decoding unit activating the photoelectric conversion elements on a line position corresponding to the address; a period determination signal generating unit that generates a period determination signal indicating one of validity and invalidity of the processing with respect to each of the divided periods; a control signal generating unit that generates a control signal for performing the processing in each of the plurality of divided periods; a processing performing unit performing the processing with respect to the line of the photoelectric conversion elements; and a supply control unit allowing the control signal to be supplied to the processing performing unit when a corresponding divided period is valid, and preventing the control signal from being supplied to the processing performing unit when the divided period is invalid.
