This paper focuses on a transmitter of image sensor communication (ISC) for the intelligent transportation system (ITS). ISC is a kind of visible light communications (VLC) that use an image sensor as a reception device. A commonly used transmitter device for ISC is an LED array as it can transmit multiple data transmission. However, it is necessary to decide the design of LED array and its transmission pattern in advance. Therefore changing the LED design and transmission pattern is difficult. In this paper, we propose to use a DMD projector for the ISC transmitter which can easily design and change a shape of transmission pattern and data rate compared with the LED array. A headlight of a vehicle, street lights, a projector of road signage are a typical example of the DMD projector usage. We, therefore, assume that a transmission pattern is projected on a road or signage for communication. In this paper, we describe our prototype using DMD projector and a high-speed camera and report an essential examination of the transmission pattern. |
