An image processing method and an image processing apparatus for color correction are provided. The image processing method for color correction comprises the steps of: (a) determining an angle on a color space according to an image data of a basic color, (b) determining a first straight line on the color space according to the angle, (c) determining a second straight line on the color space according to an image data of a pixel, wherein the second straight line is parallel to the first straight line, (d) calculating a distance between the second straight line and the first straight line in order to obtain a color intensity difference value, (e) correcting the image data of the pixel according to the color intensity difference.
