Patent ID: 8503776

Claim:
An apparatus for providing display information for color calibration of a display device, the apparatus comprising: an input unit for inputting user input information; a preprocessing unit for preprocessing the user input information input by the input unit to generate a color patch for brightness adjustment and a color patch for contrast adjustment; and a color patch display unit for displaying and outputting the color patch for brightness adjustment and the color patch for contrast adjustment that are generated by the preprocessing unit, wherein the user input information is any one of a preheating signal, color temperature information, brightness information, and contrast information, and wherein the preprocessing unit includes: a preheating unit for performing a preheating operation for stabilization of the display device in response to the preheating signal input by the input unit; a color temperature setting unit for setting a color temperature required for the display device depending on the color temperature information input by the input unit; a brightness adjustment unit for adjusting the brightness of the display device depending on the brightness information input by the input unit; and a contrast adjustment unit for adjusting the contrast of the display device depending on the contrast information input by the input unit.
