    • An image processing method and apparatus for converting image data for use in a color CRT and an image processing device each having a different color reproducible range, for example, a color printer. Color component data of color image data corresponding to a most parts of a color reproducible range of the color printer having a color reproducible region which is narrower than that of the color CTR is not converted. The hue and the brightness of color component data of color image data exceeding the color reproducible range of the color printer are not substantially converted but only chromaticness is converted. A part deviated from the color reproducible range can be approximated to the outer periphery of the reproducible range. Furthermore, the most part of the color reproducible range is correctly color-reproduced and the color image is converted so as to make a portion of the same to be a compressed space of an all color space. Therefore, a color image can be converted such that a color image can be reproduced while maintaining color continuity even if the color deviates from the color reproducible range of the color printer.
    • 一种图像处理方法和装置,用于转换用于彩色CRT的图像数据和每个具有不同颜色再现范围的图像处理装置,例如彩色打印机。 对应于具有比彩色CTR的窄的颜色可再现区域的彩色打印机的彩色可再现范围的大部分的彩色图像数据的颜色分量数据不被转换。 彩色图像数据的颜色分量数据的色调和亮度超过彩色打印机的色彩可再现范围,基本上不进行转换,只有色度被转换。 偏离颜色再现范围的部分可以近似于可再现范围的外围。 此外,颜色可再现范围的大部分是正确的颜色再现,并且彩色图像被转换,以使其一部分成为全色空间的压缩空间。 因此,即使颜色偏离彩色打印机的颜色再现范围,也可以转换彩色图像,使得可以在保持颜色连续性的同时再现彩色图像。

    • An image processing method for executing image data conversion between different types of input and output devices having different color reproduction ranges, and an apparatus therefor are disclosed. A device independent color reproduction range is calculated in, e.g., a CIE L*a*b* uniform color space, and a color reproduction range depending on a device such as a binary recording color printer is calculated. Only a saturation is compressed at a compression ratio corresponding to the ratio of the two calculated color reproduction ranges. Thus, when an output device outputs a color image, image qualities (color reproducibilities) of input and output images can be equalized. Even when a color outside the color reproduction range of the output device is to be output, a satisfactory output which preserves gradation characteristics can be obtained.
    • 公开了一种用于在具有不同颜色再现范围的不同类型的输入和输出装置之间执行图像数据转换的图像处理方法及其装置。 在例如CIE L * a * b *均匀颜色空间中计算与设备无关的色彩再现范围,并且计算取决于诸如二进制记录彩色打印机的设备的色彩再现范围。 只有饱和度以对应于两个计算出的颜色再现范围的比率的压缩比进行压缩。 因此,当输出设备输出彩色图像时,输入和输出图像的图像质量(颜色再现性)可以相等。 即使输出输出装置的颜色再现范围之外的颜色,也能获得保持灰度特性的令人满意的输出。
