Abstract
A method of enhancing a color temperature of a color image includes calculating gains for input image signals based on a predetermined gain function. A first offset value corresponding to a change in a pedetermined color temperature of output signals is calculated. A second offset value is calculated based on the gains and the first offset value. The second offset value is added to a B signal of the output signals. A compensation gain is calculated in consideration of intensity of the B signal to which the second offset value is added. The compensation gain is added to a G signal. Thus, a desired color temperature can be obtained regardless of the intensities of R, G, and B signals.
