Abstract: An image sensor is provided. The image sensor includes a pixel array including first and second pixels, the first and second pixels receiving the same transfer gate signal and outputting first and second signal voltages, respectively, a transfer gate driver receiving first and second voltages and generating the transfer gate signal, the transfer gate signal having the first voltage as its maximum voltage and having the second voltage as its minimum voltage and a compensation module detecting a variation in the second voltage, generating a compensation voltage based on the variation in the second voltage, and performing a compensation operation.

Abstract: An image sensor includes a pixel array, a column signal processor, and a column mismatch compensator. The pixel array outputs a pixel signal from each column line during a pixel measuring time, and outputs a reference signal during a reference measuring time. The column signal processor performs correlated double sampling (CDS) on the reference signal to generate a reference CDS signal, and performs CDS on the pixel signal to generate a pixel CDS signal. The column mismatch compensator compensates the pixel CDS signal based on the reference CDS signal.
