    • In magnifying a multivalued image, binary images are generated by using the respective density levels of the multivalued image as thresholds. The contour of each binary image is equivalent to an equidensity curve corresponding to each density gradient of the original multivalued image. Outline vectors of each binary image are extracted and magnified/smoothed. The contour of each binary image represents an equidensity curve corresponding to each density gradient of the magnified multivalued image. In a binary image area corresponding to a black pixel of each binary image, a pixel having a density equal to the threshold used to generate the binary image is written. This processing is sequentially performed for all the binary images from a low-density binary image to a high-density binary image to generate a multivalued image. The objected multivalued image is subjected to density gradient smoothing processing. As a result, a magnified multivalued image is obtained.
    • 在放大多值图像时,通过使用多值图像的相应浓度水平作为阈值来生成二进制图像。 每个二进制图像的轮廓等价于对应于原始多值图像的每个密度梯度的等距曲线。 提取并放大/平滑每个二进制图像的轮廓向量。 每个二进制图像的轮廓表示对应于放大的多值图像的每个密度梯度的等距曲线。 在对应于每个二进制图像的黑色像素的二进制图像区域中,写入具有等于用于生成二值图像的阈值的浓度的像素。 对于从低密度二进制图像到高密度二进制图像的所有二进制图像依次执行该处理,以生成多值图像。 对象多值图像进行密度梯度平滑处理。 结果,获得了放大的多值图像。
