    • An image processing apparatus reads an image on an original and generates lines of data by causing a carriage to perform scanning, then by referring to the data, detects chromatic color pixels that exist between two achromatic color pixels, being first and second achromatic color pixels, from among pixels in the image that has been read in the scanning direction of the carriage, and determines one of the detected chromatic color pixels as a pixel of interest and corrects the pixel of interest to an achromatic color pixel while shifting the position of the pixel of interest pixel-by-pixel N times from a pixel position adjacent to the first achromatic color pixel in a direction toward the second achromatic color pixel.
    • 图像处理装置通过使滑架进行扫描来读取原稿上的图像并生成数据线,然后参照该数据检测作为第一和第二无彩色像素的两个无彩色像素之间存在的彩色像素, 从已经在滑架的扫描方向上读取的图像中的像素之中,将所检测的彩色像素中的一个确定为感兴趣的像素,并将感兴趣的像素校正为无彩色像素,同时移位像素的位置 从与从第一无彩色像素相邻的像素位置朝向第二无彩色像素的方向像素地逐次扫描N次。
