Abstract (in Japanese) (See Japanese page) 
(in English) For the development of Intelligent Transport Systems (ITS), road-to-vehicle Visible Light Communication(VLC) has been expected.
In this study, we considered a case where the transmitter position in the captured image of the vehicle's receiver move at high speed.
We propose a method to detect the amount of movement of the transmitter in the captured image by analyzing the time-gradient value of the parallel shift of the captured image using image processing.
We conducted an experiment in a high-speed driving environment. We detected the movement of the transmitter in the captured image, corrected for the movement, and calculated the spatial-temporal gradient values.
In this way, it is possible to acquire the LED array in the captured image.
Furthermore, we confirmed that it is possible to demodulate data error-free from the acquired LED array.
