Color calibration system and method of including image processing apparatus and display apparatus

A color calibration method comprising:

• generating a graphic image which will be displayed in a display apparatus and first color patch information for color calibration of the display apparatus;
• generating second color patch information to display a color patch, based on the first color patch information and stored internal color patch information;
• and
• displaying a color patch in the display apparatus based on the second color patch information, and performing color calibration process by adjusting the displayed color patch.

A color calibration system comprising:

• an image processing apparatus and a display apparatus, wherein
• the image processing apparatus comprises a graphic card unit which outputs a graphic image and first color patch information for color calibration of the display apparatus;
• a color calibration unit which receives the output graphic image and first color patch information from the graphic card unit, generates second color patch information based on the first color patch information and stored internal color patch information to display a color patch in an additional layer separately from the graphic image, and transmits the graphic image and the second color patch information to the display apparatus;
• and
• a first control unit which controls the color calibration unit to perform color calibration process according to a color calibration feedback signal transmitted by the display apparatus;
• the display apparatus comprises a display unit;
• a detection unit which detects a color of a color patch displayed on the display unit;
• and
• a second control unit which controls the display unit to display thereon the color patch generated on the basis of the second color patch information and the received graphic image and transmits a color calibration feedback signal to the image processing apparatus according to a detection result of the detection unit.
