Abstract: In a solid-state imaging element that compares a reference signal and a pixel signal with each other, a frame rate is improved. A differential amplifier circuit amplifies a difference in potential between a pair of input nodes and outputs the difference from an output node. A transfer transistor transfers charge from a photoelectric conversion element to a floating diffusion layer. A gate of a source follower transistor is connected to the floating diffusion layer, and a source thereof is connected to one of the pair of input nodes. A measurement unit measures a gate-source voltage of the source follower transistor and supplies a measured value. A correction arithmetic unit arithmetically calculates a correction value for correcting a potential of the other one of the pair of input nodes based on the measured value.
