Abstract
An imaging apparatus according to an exemplary embodiment includes pixels, reading circuits, first current sources each including a first transistor, second current sources each including a second transistor, a first control unit configured to control outputting a current from the first transistor to the reading circuit, and a second control unit configured to perform selectively supplying a voltage to a gate of the second transistor and holding a voltage at the gate of the second transistor. When the second control unit supplies the voltage to the gate of the second transistor, the second transistor supplies the reference current and the first control unit stops outputting the current from the first transistor to the reading circuit. When the second control unit holds the voltage at the gate of the second transistor, the first control unit causes the first transistor to output the current from the first transistor to the reading circuit.
