1. An image sensor comprising:
a pixel configured to generate a pixel signal, using an analog signal processing voltage;
a ramp signal generator configured to generate a ramp signal, using the analog signal processing voltage;
a bias voltage generator configured to generate a bias voltage, using the analog signal processing voltage;
a noise compensator configured to:
generate a noise component, using a digital signal processing voltage and the analog signal processing voltage; and
add the generated noise component to the generated bias voltage; and
a conversion circuit configured to:
generate a reference voltage, based on the generated ramp signal and the bias voltage to which the noise component is added; and
generate an image signal by performing analog-to-digital conversion on the generated pixel signal, based on the generated reference voltage,
wherein the analog-to-digital conversion is performed using the digital signal processing voltage.
