    摘要： 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.

    摘要： An image processing apparatus may include an image frame determiner to determine one standard image frame and at least one reference image frame using light field data about a scene, a point spread function determiner to determine a point spread function based on sub-pixel displacement between the standard image frame and the at least one reference image frame, an image interpolator to interpolate the standard image frame into a high-resolution standard image frame having a higher resolution than the standard image frame, and an image restorer to restore a high-resolution image by updating the high-resolution standard image frame using the generated high-resolution standard image frame, the point spread function, and the at least one reference image frame.

    摘要： An apparatus and method for restoring an image are provided. The apparatus includes an edge-strength-detection module which detects an R-channel edge strength, a G-channel edge strength and a B-channel edge strength from an input image and generates an R-channel edge map, a G-channel edge map and a B-channel edge map based on the R-channel edge strength, the G-channel edge strength and the B-channel edge strength; an edge-strength-compensation module which compensates for the R-channel edge strength and the B-channel edge strength based on the G-channel edge strength; a valid-value-generation module which generates a valid value indicating a blur level based on the compensated R-channel edge strength and the compensated B-channel edge strength; a point spread function (PSF) estimation module which estimates a PSF corresponding to the valid value; and an image-restoration module which restores the input image using the PSF.
