Abstract
A data correcting method is disclosed to implement an optimum picture quality according to surrounding conditions. The data correcting method includes: converting the input data into XYZ color space data; converting the XYZ color space data into JCh color space data by applying a reference illuminance parameter to a CIECAM02 forward algorithm; inversely converting the JCh color space data into the XYZ color space data by the illuminance by sequentially applying a plurality of illuminance parameters different from the reference illuminance, to a CIECAM02 backward algorithm; inversely converting the inversely converted XYZ color space data into an RGB color space to produce correction data of each illuminance; and making a look-up table by mapping the produced correction data of each illuminance to the input data.
