色光的白平衡,印刷色彩的灰平衡,其实质是色光的矢量平衡。为了解析色光的矢量特性,把光的视神经脉冲作为离散信号,运用拉普拉斯变换和Z变换,即可得出光色变换复频谱Z=re^iθ;同时,光动量P=hv/c是线矢量,在光色变换复频谱上,变成相矢量,光子的几率振幅,变成复振幅N=re^iθ,从而证明了色光的矢量特性。通过对复频谱的积分整合,在不用三刺激值,也不用滤色器的前提下,即可在“复频谱图”的二维平面上解读颜色,并计算出3个新的颜色特征数值色相H、色彩强度C、色彩平衡度Ba,以及亮度L、色彩饱和度S、主频率v、主波长λ等颜色特征数值。无论是色光加色法还是色料减色法,都可以在复频谱及颜色特征数值的基础上,直接对颜色进行分色、合成、配色.并能给出颜色的合成效率、平衡效率以及相近颜色的色差等计算结果。
色光的白平衡,印刷色綵的灰平衡,其實質是色光的矢量平衡。為瞭解析色光的矢量特性,把光的視神經脈遲作為離散信號,運用拉普拉斯變換和Z變換,即可得齣光色變換複頻譜Z=re^iθ;同時,光動量P=hv/c是線矢量,在光色變換複頻譜上,變成相矢量,光子的幾率振幅,變成複振幅N=re^iθ,從而證明瞭色光的矢量特性。通過對複頻譜的積分整閤,在不用三刺激值,也不用濾色器的前提下,即可在“複頻譜圖”的二維平麵上解讀顏色,併計算齣3箇新的顏色特徵數值色相H、色綵彊度C、色綵平衡度Ba,以及亮度L、色綵飽和度S、主頻率v、主波長λ等顏色特徵數值。無論是色光加色法還是色料減色法,都可以在複頻譜及顏色特徵數值的基礎上,直接對顏色進行分色、閤成、配色.併能給齣顏色的閤成效率、平衡效率以及相近顏色的色差等計算結果。

White balance of color light and gray balance of printing color are the vector balance of color light, for which can we get a complex frequency spectrum of color transform Z=re^iθ , taking an optic nerve pulse, dispersing it once, and then applying the Laplace transform and the Z transform. At the same time, light momentum P= hv/c is the line vector, becoming a different one, the odds swinging of photon is N= re^iθ. Thus, this proves the vector specialty of color light. At the premise of the integral of complex frequency spectrum, without three activate value and sieve color implement,we can unscramble the colors of complex frequency spectrum figure into two dimensions, figuring out three new color specialties numerical values H,color intensity C,color balance degree Ba bright degree L, color plump degree S, main frequency v、main wavelength ), and so Ono We can directly separate, compose match colors, and get a result of a composed effect, balance effect, and the aberration of close colors by both methods of adding or losing luster.
