An image sensor includes a pixel array that includes a first pixel group and a second pixel group, each including a plurality of image pixels to generate image data. The first pixel group includes a first phase detection pixel pair including first phase detection pixels arranged adjacent to each other in a first direction and having at least one first microlens thereon, and the second pixel group includes a second phase detection pixel pair including second phase detection pixels arranged adjacent to each other in a second direction different from the first direction and having at least one second microlens thereon. The sensitivity of the first phase detection pixels is different from the sensitivity of the second phase detection pixels.

A crosstalk processing module configured to process a crosstalk of an image signal includes a correction element generation unit, a storage, and a crosstalk correction check unit. The correction element generation unit receives the image signal and input information associated with at least a size of the image signal and generates seed values and correction parameters which are used to correct the crosstalk, based on the input information and a representative channel image signal obtained by separating the image signal with respect to color. The storage stores the seed values and the correction parameters. The crosstalk correction check unit receives the image signal, receives the seed values and the correction parameters from the storage, corrects the crosstalk, and outputs a final image signal and pass/fail information indicating a pass or fail of the correction of the crosstalk based on a plurality of reference values.
