Abstract:
1. An image displaying device comprising: 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 is a lattice of which a position is to be changed for color adjustment using relations among solid colors in an RGB color space, each forming the same angle with one another, and calculates a change degree of a movement of the position of the lattice if the selected lattice is the lattice of which the position is to be changed for color adjustment; an LUT conversion unit which converts the LUT by changing the lattice based on the calculated change degree of the movement of the position of the lattice; and a lattice reference or interpolation unit which refers to or interpolates the lattice based on the converted LUT, wherein the lattice control unit determines a lattice disposed between two solid colors neighboring the solid color to be adjusted as a lattice requiring change, when adjusting one of the solid colors; and wherein the lattice control unit calculates the change degree of the movement of the position of the lattice within a distance range between the lattice to be changed and neighboring lattices.
