  • Patent number: 10225495
    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.
