    Abstract: A data processing device includes an input gamma processor, a renderer, and an output gamma processor. The input gamma processor generates first image data by linearizing input image data based on a variable gamma lookup table which changes based on a predetermined gamma weight. The renderer renders the first image data to generate second image data. The output gamma processor generates output image data based on non-linearizing the second image data based on an output gamma lookup table. The output gamma lookup table is calculated based on a reverse gamma function of the variable gamma lookup table.

    Abstract: An apparatus for encoding an image data includes a sub-pixel rendering unit and a first differential pulse code modulation (DPCM) processing unit. The sub-pixel rendering unit converts first image data of an RGB type to second image data of an RG-BG type. The DPCM processing unit generates first differential data including primary differential values corresponding to respective sub-pixels. To perform this operation, the DPCM processing unit calculates a gray value difference from a neighboring sub-pixel for each of the sub-pixels based on the second image data.
