Abstract
An image sensor including a pixel array including a plurality of sub-pixels arranged along a plurality of rows and a plurality of columns, and k number of sub-pixels representing one color pixel in conjunction with each other, where k is an integer equal to or greater than four and calibration circuitry may be provided. The calibration circuitry may be configured to receive digital image signal generated based on pixel signals output from the pixel array, calculate a color gain of the digital image signal based on a coefficient set calculated based on a reference image signal generated by a reference image sensor under a first light source having a first color temperature, store coefficient sets associated with a plurality of color temperatures including the first color temperature, and apply the color gain to the digital image signal to generate a calibrated image signal.
