Abstract: 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.

Abstract: An image sensor includes a pixel array, a micro lens array and polarizing filters. The pixel array includes a plurality of pixels. The micro lens array is disposed on the pixel array and includes a plurality of micro lenses. The micro lens overlaps a pixel group of the pixel array. The polarizing filter is disposed on the micro lens and includes a plurality of polarizing filters having at least two different polarizing phases. Accordingly, the accuracy and the reliability of the local auto white balancing may be improved.
