摘要： 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.
摘要翻译：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。

摘要： An image processing apparatus prevents an increase in random noise and the like produced by distributing a transformation error, which is produced at the time of a level-number transformation, to unprocessed pixel data. Error data X.sub.n is added to pixel data, which has entered via an input unit, by an adder. Thereafter, the resulting data is subjected to a level-number transformation by a binarizing circuit. Transformation error produced at the time of the level-number transformation is calculated by an error arithmetic unit. The transformation error thus calculated is distributed to unprocessed pixel data by an error-diffusion unit, and the error is accumulated in a line buffer memory as error data. When processing of a prescribed number of lines has ended, a line-number discriminating circuit clears the error data that has been accumulated in the line buffer memory. As a result, an increase in random noise is prevented.
