我们通过主观评价对彩色电子纸（e‐paper）的图像质量进行了量化，明确了提高图像质量的要求。在彩色电子纸领域中，已经开发了各种显示器类型，其重点在于提高显示器性能或制造成本。然而，彩色电子纸仍在开发中，与印刷纸、照片和传统显示器相比，图像质量还不够。关于未来彩色电子纸的图像质量，明确反射率、对比度、国家电视系统委员会（National Television System Committee，简称NTSC）比率等因素如何影响图像质量是非常重要的。因此，我们量化了图像质量因素，如色彩再现，色调再现和表面纹理。从我们的实验结果中，我们可以明确的显着因素和彩色电子纸的图像质量的实际范围。例如，大约30%或更高的反射率、大约8：1或更高的对比度以及20%或更高的对比度都是获得与广泛阅读的报纸的主观评价分数相当的主观评价分数的要求。
We have quantified the image quality of color electronic paper (e‐paper) by subjective evaluations and clarified the requirements for improving the image quality. In the color e‐paper field, various display types have been developed with the focus on improving the display performances or manufacture costs. However, color e‐papers are still under development, and the image quality is not sufficient when compared with printed papers, photographs and conventional displays. With respect to the image quality of color e‐paper in the future, it is very significant to clarify how reflectance, contrast ratio, National Television System Committee (NTSC) ratio, and other factors affect the image quality. Therefore, we have quantified the image quality factors such as color reproduction, tone reproduction, and surface texture. From our experimental results, we could clarify the significant factors and the practical range of image quality of color e‐paper. For instance, both the reflectance of approximately 30% or higher, contrast ratio of approximately 8:1 or higher, and NTSC ratio of 20% or higher are the requirements for obtaining subjective evaluation score that is equivalent to that of newspapers, which are read very widely.
