摘要： Provided are a method and apparatus for canceling chromatic aberration. In the method, only chrominance signals are filtered using an asymmetrical mask according to the characteristics of chromatic aberration occurring from among a luminance/chrominance coordinates system. Accordingly, it is possible to cancel chromatic aberration regardless of the characteristics of a lens and prevent the resolution of the original image from degrading.

摘要： A device and method of removing chromatic aberration which occurs in an image generated by capturing a target subject. The chromatic aberration removing device includes a chromatic aberration region detecting unit which detects a chromatic aberration occurrence region in an input image, a coefficient calculating unit which calculates a minimizing pixel value which minimizes a difference between sizes, numbers of pixels or intensities of edges of red, green, and blue (RGB) channels of the chromatic aberration occurrence region, a chroma signal processing unit which removes chromatic aberration in the chromatic aberration occurrence region, and a purple fringing removing unit which removes purple fringing.

摘要： A method and apparatus for eliminating chromatic aberration; in an embodiment, only the chrominance signal is filtered in the luminance/chrominance coordinates so as to eliminate the chromatic aberration so that the chromatic aberration can be eliminated regardless of a property of a lens. In addition, there are advantages in not only eliminating the chromatic aberration but also preventing resolution of the original image from being damaged.
