Abstract

An image sensor compensates for noise. The image sensor includes a pixel array that includes a common monitor output line, a first monitoring pixel outputting a first monitoring signal, a second monitoring pixel outputting a second monitoring signal, and an active pixel configured to output a sensing signal based on an incident light. The image circuit also includes a binning circuit that receives the first and second monitoring signals through the common monitor output line and generates an average monitoring signal by performing binning on the first and second monitoring signals, and an analog-to-digital converter that detects an alternating current (AC) component of the average monitoring signal and couples the sampled AC component of the average monitoring signal to the sensing signal, thereby compensating for noise.
