Abstract

An image sensor including a pixel of a first tap. a pixel of a second tap. an operational amplifier configured to perform an auto zeroing operation with a pixel signal of the pixel of the second tap applied, and perform an operation for comparison between a ramp voltage and a signal output from the pixel of the first tap, with a pixel signal of the pixel of the first tap applied, and a counter circuit configured to generate a digital code in response to an output of the operational amplifier.
