  • Image sensor for compensating column mismatch and method of processing image using the same
    Patent number: 9467634
    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.
