摘要： 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.

摘要： A luminance/chrominance (Y/C) signal separating device utilizing motion estimation and compensation. According to the device, the image motion is detected in the unit of a 2.times.2 (sample.times.line) block to separate an NTSC television signal into the Y and C signals. As a result of the motion detection, a three-dimensional Y/C signal separation is performed with respect to a still image, while a three-dimensional Y/C signal separation with the motion estimation and compensation in the unit of the 2.times.2 (sample.times.line) block in a predetermined region of the previous frame is performed with respect to a moving image. A two-dimensional Y/C signal separation is performed with respect to the moving image whose motion is not compensated in the unit of a 2.times.1 (sample.times.line) block in the present frame.

摘要： Method and apparatus for sharpening edges and details of a digital image without amplifying noise in the digital image provide an output image which is the sum of the input image and its adaptively-amplified high frequency components, which adaptively amplified high frequency components are obtained by subtracting a low-pass filtered image from the input image. An adaptive amplification factor for the high frequency components is determined as a function of a variance of the pixel values surrounding a pixel and the noise power of the imaging system.

摘要： 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.

摘要： 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.
