摘要

本研究將以色彩學的角度來探討光譜解析度對色彩擷取的影響，且在考慮人眼色彩寬容量的情況下，找到合理解析度來擷取未失真光譜，來改善背光源的色彩穩定性並降低擷取成本。接著，嘗試在不同光譜解析度、不同背光源的情況下，分析其光譜分佈、色度資訊、總能改變及色差變化，驗證其結果是否有一致性，且歸納出擷取誤差的因素。
最後，由合理解析度10nm來擷取LED光譜飄移現象，研究結果顯示其色差單位值小於色彩擷取晶片35倍之多，搭配光柵分光晶片的技術，就可應用在擷取元件來校正色彩，讓顯示器能夠完美地呈現真實色彩。

This thesis is studying the effect of color measurements by different resolution. Try to choose the limit resolutions conforming human visual sensitivities to measuring the spectrums. Change different kinds of light sources to analyze the spectrum, colorimetry informations, and chromatic aberrations and check it reach our goal or not.
Finally, choosing the limitative parameters to get the LED spectral shift and compare with color sensors of Avago Technology. The result shows the effort of the spectrum measuring is better than the color sensor. By the study of the spectral-chip, this method will be applied to adjust the color expression.
