Patent ID: 8305396

Claim:
A method for correcting a color of a display device, the method comprising: converting input R/G/B data into Y/Cb/Cr data; calculating a weight by an exponential function using a dispersion and a distance between an input value and a target value of the Y/Cb/Cr data, comparing the calculated weight with a target color range so as to detect a target color region, and calculating a detection probability; detecting an average value, a minimum value and a maximum value of the Y/Cb/Cr data for the detected target color region from a previous frame; calculating a correction constant using the average value, the minimum value and the maximum value of the Y/Cb/Cr data, a predetermined target value of the Y/Cb/Cr data, and the Y/Cb/Cr data which is detected as the target color region and is input, adding the detection probability to the calculated correction constant as the weight so as to calculate a correction amount, correcting the input Y/Cb/Cr data using the calculated correction amount so as to output the Y/Cb/Cr data; inversely converting the corrected Y/Cb/Cr data into R/G/B data; and displaying the converted R/G/B data on the display device.
