本研究針對彩色電子紙的影像顯示技術，從留白與真實色彩的角度出發，提出了一套完整的半色調處理與色彩校正方法，旨在解決彩色電子紙在色彩表現與畫面穩定性方面的問題。透過基於 Bayer 矩陣的優化搜索次序，顯著提升了演算法的收斂速度與處理效率，同時有效降低了影片播放過程中的閃爍現象。此外，針對多粒子彩色電子紙的影片播放需求，本研究設計了一套專用硬體架構，成功將系統移植至 FPGA 平台，滿足高效能的應用需求。實驗結果顯示，所提出的方法在色彩準確度、畫面品質與計算效率上均優於現有技術，為彩色電子紙的影像顯示提供了一種高效且創新的解決方案，並為後續技術的優化與發展奠定了基礎。

This study focuses on image display technologies for color electronic paper (ePaper), proposing a comprehensive halftoning and color correction methodology from the perspectives of blank and true color. The proposed methods aim to address challenges in color accuracy and display stability for color ePaper. By leveraging a search sequence based on the Bayer matrix, the algorithms significantly enhance convergence speed and processing efficiency while effectively reducing flicker during video playback. Additionally, a dedicated hardware architecture was designed for video playback on multi-particle color ePaper (MPCeP), successfully implemented on an FPGA platform to meet the demands of high performance. Experimental results demonstrate that the proposed methods outperform existing techniques in terms of color accuracy, image quality, and computational efficiency, providing an effective and innovative solution for image display on color ePaper and laying a foundation for further optimization and development in this field.
