CHIPSET FOR GENERATING COLOR TRANSFORM COEFFICIENT AND METHOD FOR CONTROLLING THE SAME, AND APPARATUS FOR IMPROVING QUALITY OF PICTURE OF HDTV SYSTEM USING THE SAME

摘要

PURPOSE: A chipset for generating color transform coefficient and a method for controlling the same, and an apparatus for improving the quality of a picture of an HDTV system using the same are provided to easily improve color representation characteristics of an HDTV. CONSTITUTION: A TV signal receiving unit(12) receives digital broadcasting image signals transmitted from a broadcasting station. A preprocessing unit(18) adjusts the size of an image to fit for an actual size of a display device, or executes basic image transform. A color transform coefficient generating chipset(20) generates a color transform coefficient for obtaining the optimum quality of the image of a digital TV and an HDTV. A postprocessing unit(22) transforms the image by using the color transform coefficient obtained from the color transform coefficient generating chipset and a color preference data coefficient obtained from a user. An RGB display unit(16) displays the transformed RGB image on a screen.
