    Abstract: A liquid crystal display (LCD) device includes: a data source, for generating a N-bit pixel data, N being a positive integer; a digital gamma correction unit, coupled to the data source, for performing digital gamma correction on the pixel data to generate a (N+M)-bit digital gamma correction pixel data, M being a positive integer; an image dithering unit, coupled to the digital gamma correction unit, for performing image dithering on the digital gamma correction pixel data to generate a (N+M−K)-bit dithering compensation pixel data, K being a positive integer; and a converter, coupled to the image dithering unit, for converting the dithering compensation pixel data into an output image. A bit number of the converter is lower than a bit number of the digital gamma correction unit.

    Abstract: An image processing apparatus for adjusting the luminance of a target pixel of an image is provided. The target pixel includes original pixel data and corresponds to a mask value. The image processing apparatus includes a luminance detection unit, a luminance compensation unit and a mapping unit. The luminance detection unit generates an original luminance value according to the original pixel data. The luminance compensation unit adjusts the original luminance value according to a non-linear function to generate a compensated luminance value. The mapping unit generates adjusted pixel data according to the compensated luminance value. The non-linear function at least includes a first monomial function, which has a base part associated with an inverse value of the original luminance value and an exponent part associated with the mask value.
