一般影像與多粒子彩色電子紙之間的色域範圍存在顯著差異,若直接將影像呈現於彩色電子紙上,將引發色彩偏差和失真問題。因此,本研究提出一套獨特的多粒子彩色電子紙色彩重現系統,旨在創造出與原始影像在視覺上極度接近的色彩再現效果。此系統僅需進行少量的色彩量測,即可獲取校正參數,有效提高了在生產線上進行色彩校正的效率。此外,本研究亦考量電子紙的色域特性,提出了嶄新的色域映射演算法以及誤差擴散演算法。實驗結果顯示,提出的方法能夠在彩色電子紙上最大程度地再現對比度與色彩飽和度。最後,為此色彩重現系統設計並實現了一個即時影像處理硬體架構,並提出了一種新的誤差擴散流水線架構,且在FPGA上進行了驗證。
Significant discrepancies exist between the color gamut range of conventional images and that of multi-particle color electronic paper. Displaying images directly on color electronic paper can lead to color inaccuracies and distortions. Therefore, this study proposed a color reproduction system for multi-particle color electronic paper, aiming to create color representations that are visually very similar to the original images. This system requires only fewer color measurements, thereby effectively enhancing the efficiency of color calibration on the production line. In addition, this study considered the color gamut characteristics of electronic paper and introduced new color gamut mapping and error diffusion algorithms. Experimental results show that the proposed methods can maximize the contrast and color saturation on color electronic paper. Finally, a hardware architecture for real-time image processing was designed and implemented for this color reproduction system, and a new pipeline architecture for error diffusion was proposed. The hardware performance was validated on an FPGA.
