  • Patent number: 8750641
    Abstract: Provided are an apparatus and method for correcting distortion of an image. The method includes finding center point vectors including lens distortion center information about an image and dividing the image into at least two blocks on the basis of the center point vectors, and determining representative directions of the at least two divided blocks and removing outlier vectors not indicating the representative directions from the blocks to estimate a lens distortion center. Accordingly, accurate image correction is enabled by estimating distortion centers of images generated by devices equipped with any lens. Also, image content improving lens distortion correction performance is differentiated from image content degrading the same by picking out image content improving lens distortion center estimation performance, so that a superior image correction effect to other image correction techniques can be obtained.

    Abstract: Provided are an apparatus and method for processing an image. The apparatus includes a detector configured to form one group with pieces of pixel information on an edge of a received image, detect line segments, and generate a plurality of curves using the detected line segments, an optimizer configured to apply a weight to a cost function based on the plurality of generated curves according to distance from the center of the image, define a curve having a shorter length than a threshold value as an outlier and a curve having a greater length than the threshold value as an inlier, remove the outlier, and estimate a distortion level parameter, and a corrector configured to correct a position of a pixel with a correction value using the distortion level parameter. Accordingly, it is possible to correct lens distortion of even an image that has not been directly photographed, and to correct images generated by devices equipped with any lens rather than a specific camera or photographing apparatus.

  • Patent number: 8358835
    Abstract: A method for detecting and correcting a chromatic aberration, and an apparatus and method for processing an image using the same are provided. A chromatic aberration is detected by dividing an edge portion of the image into static areas where a color varies below a reference value and a dynamic area where a color varies above the reference value, calculating a intensity difference value between at least one reference color and a comparative color for each of the static areas and the dynamic area, and determining at least one pixel having a intensity difference value exceeding a range of intensity difference values in the static areas among pixels in the dynamic area, as a chromatic aberration region. The chromatic aberration is corrected by correcting the intensity difference value for the pixels in the chromatic aberration region using a correction value in the intensity difference value range in the static area.

  • Patent number: 8345967
    Abstract: A method and apparatus for processing an image to create a grayscale image are provided. The method includes converting, in a color image consisting of a plurality of pixels, a pixel value of each pixel in a RGB color space into a pixel value in a new color space through color space conversion, extracting color information using the pixel value in the new color space, calculating a luminance change amount of each pixel using the extracted color information, calculating a luminance value for the grayscale image by combining an original luminance value of each pixel and the luminance change amount, and creating the grayscale image according to the calculated luminance value. In converting color image into grayscale image and representing the grayscale image, the luminance change amount is set according to a property of each color perceived by humans and added to original luminance value, thereby explicitly discriminating among objects.

  • Patent number: 7715648
    Abstract: An apparatus and method for compensating images in a display device is disclosed. Distortion ratios of image blocks are calculated based on a gray value difference between each of a plurality of pairs of pixels in the image blocks that face each other at a boundary between the image blocks. Compensation parameters are set based on the calculated block distortion ratios. Distortion compensation values of the image blocks are calculated based on the gray value difference and the set compensation parameters. The image blocks are then compensated according to the calculated distortion compensation values.
