Abstract
Provided is a solid-state imaging element including a pixel circuit and a comparison transistor. In the solid-state imaging element, the pixel circuit generates a pixel signal and outputs the pixel signal to a vertical signal line. Further, the comparison transistor has a source connected to a constant current source configured to supply a constant current to the vertical signal line. The comparison transistor has a gate to which a predetermined reference signal is input. Further, the comparison transistor has a drain from which a comparison result between the pixel signal and the reference signal is output.
