Abstract
An imaging apparatus includes a pixel configured to generate a signal in accordance with an incident light by a photoelectric conversion; a differential amplifier including a first input terminal to which a voltage based on the signal from the pixel is input, and a second input terminal to which a reference voltage is input; a current supply unit configured to supply a bias current to the differential amplifier; and a comparing unit configured to compare the voltage of the first input terminal of the differential amplifier with a threshold voltage, and configured to output a control signal based on a comparison result to the current supply unit, and the current supply unit changes a magnitude of the bias current supplied to the differential amplifier in accordance with the control signal input from the comparing unit.
