Method and apparatus for correcting chromatic aberration of image
Provided are a method and apparatus for correcting chromatic aberration of an image, the method and apparatus used in an image processing apparatus for an image pickup device or a display image processing apparatus. The chromatic aberration correction apparatus includes a chromatic aberration region sensing unit analyzing a luminance signal of an input image and sensing a region having chromatic aberration; a color gradient calculation unit calculating a first weight, which indicates a degree of chromatic aberration, based on a difference between gradients of color components of the input image; a luminance gradient calculation unit calculating a second weight, which indicates the degree of chromatic aberration, based on gradients of luminance components of the input image; and a chrominance correction unit correcting chrominance of a pixel of the input image, which is included in the sensed region, based on a value obtained by multiplying the first weight by the second weight.
