Publication number: 20240253558Abstract: The present invention addresses the problem that the road surface area allowed for projecting an image is limited, there is a restriction on the number of parts into which the image can be divided, and it is hard to achieve an intended visual effect even if individual images are sequentially projected. A control unit (31) controls three light sources (21a to 21c) so that, among three individual images (5a to 5c), projection of an image (5b) to be projected second is started at a time point (t4) later than a time point (t3) at which a period of 250/3 milliseconds has elapsed from a projection start time point (t1) for an image (5a) to be projected first. Consequently, the visual effect of sequential projection of individual images is more easily achieved than when the projection of the second individual image (5b) is started at the time (t3).Type: ApplicationFiled: May 16, 2022Publication date: August 1, 2024Applicant: Ichikoh Industries, Ltd.Inventors: Yuichiro WASHI, Hideto KURIMOTO
