Abstract:
1. An image processing apparatus, comprising: 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; 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 and to output the image signal having the corrected color coordinate value if the difference is less than the reference value; and a user input unit which is provided to input a target color coordinate value for another color, and a color converter which converts the color coordinate value of the image signal input by the contrast enhancer into the target color coordinate value, wherein the controller controls the color converter to convert the color coordinate value of the image signal for a color region defined as a group of colors neighboring the other color, to the target color coordinate value, and wherein the controller controls the color coordinate value of the color correction region for each frame, the color coordinate value being output by the color converter as the converted image signal, to be supplied as a feedback to the contrast enhancer.
