    • 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.
    • 提供了一种用于处理图像以创建灰度图像的方法和装置。 该方法包括:通过颜色空间转换将RGB颜色空间中的每个像素的像素值在多个像素组成的彩色图像中转换为新颜色空间中的像素值,使用图像中的像素值提取颜色信息 使用所提取的颜色信息计算每个像素的亮度变化量,通过组合每个像素的原始亮度值和亮度变化量来计算灰度级图像的亮度值,以及根据计算出的每个像素的灰度图像来创建灰度图像 亮度值。 在将彩色图像转换为灰度图像并表示灰度图像时,根据人感知的每种颜色的属性来设置亮度变化量,并将其添加到原始亮度值,从而明确地区分对象。

    • 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.

    • 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.
