Abstract
The present invention provides an image compensation apparatus, by which a hardware structure is simplified and by which resolution of a remanded color gamut is enhanced when an inputted digital image is compensated to fit the characteristics of a display device. The present invention includes a 3-dimensional look-up table storing 3-dimensional transformation data corresponding to upper n-bits of an input image and a color interpolation unit outputting a final color-transformed image by performing linear interpolation using the 3-dimensional transformation data outputted from the 3-dimensional look-up table and 3-dimensional data corresponding to lower m-bits of the input image.
