摘要
C IEDE 2000色差公式是迄今为止最为先进的色差计算公式。但是,此公式在色彩工作的使用过程中发现其在某些数据点的计算上出现间断,即数学中常提到的不连续性。本文使用数学不连续性的方法旨在从理论上证明公式中存在的小的数学不连续性。计算结果表明,此公式存在三方面的不连续性,即平均色相角的计算、色相差的计算和色相角在经过360°时均存在不连续性。最后,简单的介绍了公式中不连续性的应用。
The CIEDE 2000 Color difference formula is the most advanced one for color difference calculation. But, it is found that there are some errors in some points＇calculations when the formula is using in color art, that is, somewhat discontinuity in mathematic. Theoretically, these small mathematical discontinuities were pointed out in the formula with mathematic discontinuity method, The result indicated that there are three discontinuities in this formula： the discontinuities of the calculation of average hue angle, the calculation of hue differences, and when the hue angle coming through 360°. The utility of the discontinuities was introduced.
