Abstract
印刷式彩色濾光陣列電子紙具有快速驅動和準確色彩控制的優勢。然而，它的色域比多色彩電子紙狹窄，且輸出響應曲線通常是非線性的，這導致顏色和色調再現困難。本論文討論了傳統影像處理流程在這種新型彩色電子紙上的應用問題，並提出了解決非線性響應問題的方法。通過這種新影像流程，可以顯著改善顯示品質。
The color electronic paper (e-paper) based on a printed color filter array offers the advantage of rapid driving capability and accurate intensity control for each color channel. However, its color gamut is comparatively narrower than that of multi-pigment color e-paper, and the output response curve is generally nonlinear. This leads to difficulties in color and tone reproduction when displaying an image on this new color e-paper. This paper discusses the practical issue of applying the traditional image processing pipeline to this new color e-paper and proposes an alternative approach to address the nonlinear response issue in printed color e-paper. With the proposed image pipeline, significant improvements in display quality can be achieved.
