SOLID-STATE IMAGING ELEMENT, DRIVING METHOD OF THE SAME, AND ELECTRONIC DEVICE EQUIPPED WITH THE SAME

摘要

A pixel includes 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 detection portions, and an output portion which outputs a signal corresponding to the potential of a detection portion. In a state where the connection/separation control portion connects the 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 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.

1. A solid-state imaging element comprising:
a pixel area in which a plurality of pixels are aligned,
wherein the pixel includes:
a photoelectric conversion portion which performs photoelectric conversion;a transmission portion which transfers a charge from the photoelectric conversion portion;a plurality of detection portions which detect the charge transferred by the transmission portion;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; andan output portion which outputs a signal corresponding to potential of the detection portion,wherein, 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, andwherein 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.
