| 中文摘要: |
| 通过实验比较和分析了 CGATS 公式法、灰平衡测试表实验法、中性灰密度计算法和距离加权法获得的灰平衡数据,提出了基于距离加权法的改进方法。 实验结果表明,该改进方法获取的灰平衡数据在整个阶调范围内,打印出中性灰与之对应的黑之间的色差 △Eab均在 1 个单位之内,利用该灰平衡数据能够有效控制色彩复制过程的颜色偏差,保证色彩复制过程顺利实施。 |
| 英文摘要: |
| CGATS algorithm, gray balance test chart algorithm, neutral gray density algorithm and weighted distance algorithm were compared and analyzed through experiment. Improved gray balance data acquirement method based on weighted distance algorithm was put forward. Experimental results showed that the color difference △Eab between gray color produced by gray balance data acquired by the improved algorithm and the related black is less one unit in full tone; Application of the gray balance data can reduce color difference effectively in color reproduction. |
