1. An image processing method comprising: receiving an image comprising a plurality of pixels; compensating a color temperature of at least one pixel of the image according to a color of the at least one pixel; and outputting the image according to a result of the compensating, wherein the compensating comprises: measuring a color temperature of the at least one pixel; and applying a color temperature compensation value to the at least one pixel based on the measured color temperature and the color of the at least one pixel, and wherein the applying comprises: analyzing the color of the at least one pixel; determining whether the color of the at least one pixel exists in a look up table; and in response to determining that the color of the at least one pixel exists in the look up table, determining the color temperature compensation value corresponding to the color and the measured color temperature of the at least one pixel by using the look up table and applying the determined color temperature compensation value to the at least one pixel.
