Claim 14:
15. A semiconductor device for a display device, comprising:
a gamma converter configured to receive n-bit image data and gamma-correct the n-bit image data to generate m-bit gamma image data;
a storage circuit configured to store a look-up table comprising a plurality of compensation values corresponding to the m-bit gamma image data;
a compensation circuit configured to:
identify two compensation values corresponding to a high-order bit data value and a first low-order bit data value of the m-bit gamma image data, from among the plurality of compensation values, and
compensate the m-bit gamma image data based on a final compensation value obtained by interpolating the two compensation values using a second lower-order bit data value of the m-bit gamma image data to output a compensated gamma image; and

a dithering circuit configured to dither the compensated gamma image into n-bit data and outputs the n-bit data,
wherein m and n are natural numbers greater than one.
