ABSTRACT:
A color correction device, for strengthening or weakening a specific color according to the selection of a user, is provided. In a color correction device, the area of an input color signal is determined according to chrominance axes, coefficients of a corresponding coordinate of the chrominance axes are read from a storage memory, and a matrix operation is performed on the input color signal before it is output. An index table divides the area defined by chrominance axes on the basis of r, g, and b signals. A storage memory contains coefficients corresponding to the respective coordinate positions for correcting the color signal to represent colors similarly to the original color of the subject. A specific color may be strengthened or weakened based on the selection of a user, due to the addition of a second storage memory which contains, coefficient tables for designating areas according to the chrominance axes corresponding to a color to be strengthened or weakened. Therefore, a user can strengthen or weaken a desired color due to the addition of an additional coefficient table memory.
