Abstract
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.
