在本文中，我们提出了一种基于图像传感器的可见光通信(IS-VLC)系统，该系统在用于广告的数字标牌中提供视觉信息。IS-VLC系统的一个重要问题是在传输数据信息时视觉信息的恶化。人眼对亮度敏感，但对色差不敏感，因此，我们提出了色差的调制。我们从视觉信息的质量和数据信息的通信质量两个方面对该系统的性能进行了评估，并阐明了该系统的有效性。
In this paper, we propose an image-sensor-based visible light communication (IS-VLC) system that provides visual information in digital signage used for advertisements. One important issue of IS-VLC systems is the deterioration of visual information while transmitting the data information. Human eyes are sensitive to luminance but not to color difference; therefore, we propose the modulation of color difference. We evaluate the performance of the proposed system in terms of both the quality of visual information and communication quality of data information, and clarify the effectiveness of the proposed system.
