本文介绍了一种照明技术，它使我们能够无形地附加信息到一个真实的对象，通过使用照明光和提取的信息，从视频图像的对象捕获的视频摄像机。时间和空间颜色强度调制将信息嵌入到光束的颜色分量中。首先，我们评估了附着在人眼可见的真实的物体上的信息对人眼的不可见性。实验表明，调制幅度的上限值，满足每个颜色分量的不可见性。实验结果表明，蓝色分量具有比红色和绿色分量高得多的不可见程度。我们还研究了附加到对象的信息的可读性与摄像机时，信息嵌入在光束的蓝色分量。实验结果表明，调制幅度的下限值，满足可读性。实验结果给出了满足物体信息不可见性和可读性要求的蓝色光强调制幅度范围。我们的实验结果证明了所提出的技术的有效性。
This article describes a lighting technique which enables us to invisibly attach information onto a real object by using illumination light and to extract the information from a video image of the object captured with a video camera. A temporally and spatially color-intensity modulation embeds information into a color component of the light beam. First, we assessed the invisibility to the human eye of the information attached onto a real object visible to the human eye. The experiments showed an upper limit value of modulation amplitude that satisfied invisibility for each color component. The experimental results revealed that the blue color component had a much higher degree of invisibility than the red and green components. We also examined the readability of the information attached to the object with a video camera when the information was embedded in the blue color component of the light beam. The experimental results showed a lower limit value of modulation amplitude that satisfied readability. The experimental results showed the range of modulation amplitude of intensity in the blue color that satisfied the invisibility and readability of the information attached to the object. The results of our experiments demonstrated the effectiveness of the proposed technique.
