    • A color image is processed into a renderable image. The color image comprises a plurality of pixels. Each pixel has colorimetry defined in a first color space. The renderable image comprises a plurality of renderable pixels defined by a device-vector in a second color space. For each pixel: a device-vector defined in the second color space is selected (301) based on the colorimetry defined in a first color space of the pixel. The device-vector comprises a plurality of elements. Each element includes an identifier and an accumulated weighting. An element of the selected device-vector is reselected (303) until the accumulated weighting (a) is greater than a threshold value (t) associated with the pixel (305). The levels for each color of the second color space (or mappings) for the currently selected (307) element of the selected device-vector is determined (309) to convert the pixel into a renderable pixel.
    • 彩色图像被处理成可渲染图像。 彩色图像包括多个像素。 每个像素具有在第一颜色空间中定义的比色法。 可渲染图像包括由第二颜色空间中的设备向量定义的多个可渲染像素。 对于每个像素,基于在像素的第一颜色空间中定义的比色法,选择(301)在第二颜色空间中定义的设备矢量。 装置矢量包括多个元件。 每个元素包括标识符和累积加权。 重新选择选择的设备向量的元素(303),直到累积加权(a)大于与像素(305)相关联的阈值(t)。 确定所选择的设备向量的当前选定(307)元素的第二颜色空间(或映射)的每种颜色的级别(309)以将像素转换成可渲染像素。
