摘要： Image restoration by restoring a high-frequency component of a deteriorated image. A high-frequency image information predicting and stabilizing method includes: determining a shooting area, which is a high-frequency area that includes an overly-restored high-frequency component, in an input image; predicting a high-frequency component of the input image by applying different deterioration models to the shooting area and a remaining area in the input image; and stabilizing a high-frequency component of an edge area by using an edge blur kernel determined to be parallel to an edge direction of the input image.

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 method of and apparatus for removing color noise are provided. The apparatus includes a first filtering unit, a subtracting unit, a second filtering unit, and an adding unit. The first filtering unit removes color noise from color data of a first channel among input interpolated color data and outputs filtered color data of the first channel. The subtracting unit calculates a difference between each of input color data of a second channel and a third channel among the input interpolated color data and the filtered color data of the first channel and outputs differential images. The second filtering unit selects an intermediate differential image among the output differential images and previously filtered differential images and outputs filtered differential images. The adding unit adds the filtered color data of the first channel and the filtered differential images and outputs filtered color data of the second channel and the third channel.
