Abstract
An image sensor includes a reference voltage generation unit that generates a reference voltage that alternately decreases and increases at a constant rate in an operation mode of the image sensor to convert analog signals of detected incident light to a digital value using the reference voltage to determine an intensity of the incident light with high sensitivity and high signal-to-noise ratio.
