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.

A device and method for performing a coloring set operation for a specific region on a screen of a video signal process device which designates the specific region on a liquid crystal monitor and displays the specific region with a specific color onto the screen. The method includes determining whether the specific region is designated by a user in response to an input corresponding to a coloring mode and a specific region select mode; setting a luminance signal level of the specific region, if the specific region is designated and maintaining a color phase in a default state; if a color up/down input is entered, performing an up/down operation for the color phase by a predetermined angle to set the color phase; and completing the coloring set operation in response to an input corresponding to a coloring completion mode.
