Patent ID: 8581925

Claim:
A method for correcting video input data to display an image on a Liquid Crystal Display (LCD) panel, wherein the image is displayed by continuously scanning and outputting of the video input data, the method comprising: detecting illuminance information external to the LCD panel surrounding; converting the video input data into XYZ color space data; utilizing the detected illuminance information to obtain reference illuminance parameters; if it is determined that the reference illuminance parameters are different from those in a standard environment: applying the parameters of the standard environment to execute a CIECAM02 forward algorithm to convert the XYZ color space data into JCh color space data; sequentially applying the referenced illuminance parameters other than the standard environment to execute a CIECAM02 backward algorithm to inversely convert the JCh color space data into the XYZ color space data, wherein the reference illuminance parameters other than the standard environment comprises parameters pertaining to a dim environment and a dark environment; inversely converting the inversely converted XYZ color space data into an RGB color space to produce correction data of each illuminance; making a look-up table by mapping the produced correction data of each illuminance to the video input data; and displaying the correction data on the LCD panel, if it is determined that the reference illuminance parameters are the same as those in the standard environment, directly displaying the video input data on the LCD panel without performing data correction.
