GAMMA DIFFERENCE COMPENSATING APPARATUS, METHOD OF COMPENSATING GAMMA DIFFERENCE USING THE GAMMA DIFFERENCE COMPENSATING APPARATUS, AND DISPLAY SYSTEM INCLUDING THE GAMMA DIFFERENCE COMPENSATING APPARATUS

摘要

A gamma difference compensating apparatus includes a first gamma curve generating part, a front luminance measuring part, a front gamma calculating part, a second gamma curve generating part and a gamma compensating part. The first gamma curve generating part outputs a first gamma curve data. The front luminance measuring part measures a luminance of a left area from a front of the left area, measure a luminance of a right area from a front of the right area, and output a front luminance data. The front gamma calculating part outputs a front gamma data based on the front luminance data. The second gamma curve generating part applies the front gamma data to the first gamma data and output a second gamma curve data. The gamma compensating part compensates a gamma value of the left area and a gamma value of the right area.
