The apparatus for correcting a color reproduced by a video device according to peripheral brightness includes: a lookup-table-creation unit which creates a lookup table based on saturation of the video device and brightness of peripheral conditions; a color-correction unit which corrects the color reproduced by the video device according to the created lookup table; and a color-error-compensation unit which compensates for color error resulting from correction of the color. The method of correcting a color reproduced by a video device according to peripheral brightness includes: creating a lookup table based on saturation of the video device and brightness of peripheral conditions; correcting the color reproduced by the video device according to the created lookup table; and compensating for color error resulting from correction of the color.

The image displaying device includes a lattice selection unit which selects a lattice of a look-up table (LUT) for reference of each pixel of an input image, a lattice control unit which determines whether the selected lattice requires to be changed for color adjustment and calculates a change degree of the lattice, an LUT conversion unit which converts the LUT by changing the lattice based on the calculated change degree, and a lattice reference/interpolation unit which refers to or interpolates the lattice based on the converted LUT. Accordingly, the LUT can be updated real time, thereby realizing more accurate adjustment of color.
