Zusammenfassung:The present technology relates to a solid-state imaging element in which satisfactory S/N can be achieved with respect to both a signal in a high brightness mode and a signal in a low brightness mode and reset noise can be appropriately removed, a driving method thereof, and an electronic device equipped therewith. A pixel includes a plurality of detection portions which detect transferred charges, a reset portion which resets the plurality of detection portions, a connection/separation control portion which controls connection and separation of the plurality of the detection portions, and an output portion which outputs a signal corresponding to potential of the detection portion. In a state where the connection/separation control portion connects the plurality of detection portions, the output portion outputs a connection-state reset level signal and a connection-state output signal and, in a state where the connection/separation control portion separates the plurality of detection portions, the output portion outputs a separation-state reset level signal and a separation-state output signal. A first pixel signal is generated by a difference between the connection-state reset level signal and the connection-state output signal and a second pixel signal is generated by a difference between the separation-state reset level signal and the separation-state output signal.
