  • Patent number: 11523070
    Abstract: Color mixing between pixels is prevented in a solid-state imaging element in which a pair of pixels for detecting the phase difference of a pair of light rays are arranged. A pair of photoelectric conversion elements receive a pair of light rays made by pupil-splitting. A floating diffusion layer generates a pair of pixel signals from electric charge transferred from each of the pair of photoelectric conversion elements. A pair of transfer transistors transfer the electric charge from the pair of photoelectric conversion elements to the floating diffusion layer. In a case of detecting the phase difference of the pair of light rays from the pair of pixel signals, the control unit takes control so that back gate voltages that include the back gate potentials of both of the pair of transfer transistors with respect to the potential barrier between the pair of photoelectric conversion elements have values different from values in a case of synthesizing the pair of pixel signals.
