ABSTRACT:
An image processing apparatus, includes: a contrast enhancer which changes a color coordinate value of a color correction region in an image signal, which corresponds to a color to be corrected within the image signal, to a corrected color coordinate value in a range to perform a color correction; and a controller which determines a difference between the color coordinate values before and after the color correction by the contrast enhancer, and controls the contrast enhancer to output the image signal having the unchanged color coordinate value if the difference is greater than or equal to a reference value.
