Abstract
An image sensor includes a pixel array, a ramp signal generating circuit configured to output a first reference ramp signal of a first slope as a first ramp signal in a first period and a second reference ramp signal of a second slope as the first ramp signal in a second period, an offset voltage sampling circuit configured to, to sample an offset voltage based on a DC level of the first reference ramp signal, to output the first ramp signal in the first period, and to output a signal obtained by adding the offset voltage to the first ramp signal as a second ramp signal in the second period, a buffer configured to buffer the first ramp signal and the second ramp signal, and an ADC circuit configured to compare a pixel signal from the pixel array with the first ramp signal or the second ramp signal.
