Abstract
An imaging device includes pixel circuit including a generation unit generating a voltage; a capacitor having a first electrode to which the voltage is applied; a first amplifier having a first input terminal, connected to a second electrode of the capacitor, and a second input terminal, to which a first reference voltage is applied to, to output a result by comparing the voltage with the first reference voltage; a switch unit controlling a connection between the output of the first amplifier and the first input terminal; and a second amplifier having a third input terminal, to which the output of the first amplifier is connected, and a fourth input terminal, to which a second reference voltage is applied, to output a result by comparing the voltage with the second reference voltage, in which a first gain of the first amplifier is lower than a second gain of the second amplifier.
