- Provided is a pixel circuit. The pixel circuit includes a conversion element configured to form a voltage of an input level corresponding to a magnitude of a received energy at a first node, a first transistor configured to adjust the voltage of the first node to a first level in response to a first signal received at a first time interval, a first capacitive element configured to form a voltage at a second node based on the voltage of the first node, a second transistor configured to adjust a level of the voltage of the second node to a second level in response to the first signal, a third transistor configured to form a voltage at a third node, the voltage having a level corresponding to the level of the voltage of the second node, a fourth transistor configured to output a current corresponding to the voltage of the third node in response to a second signal received in a second time interval after the first time interval, and a fifth transistor configured to adjust the voltage of the third node to a third level in response to a third signal received in a third time interval after the second time interval.
