Abstract
It is possible to prevent a black level output based on incidence of high brightness light. An imaging device includes: a signal line whose potential changes based on a charge stored according to a current flowing at a time of readout of a signal from a pixel; a signal line reset transistor that resets the potential of the signal line; a signal line reset level generation unit that generates a reset level of the potential of the signal line; a signal line clip transistor that clips the potential of the signal line; and a signal line clip voltage setting unit that sets a signal line clip voltage used to generate a clip level of the potential of the signal line. The signal line reset level generation unit may be a diode connection transistor.
