Publication number: 20220191072Abstract: An automobile includes an automotive lamp and an in-vehicle controller. A sensor generates image data. An encoder divides the image data into multiple data frames, and encodes the data frame thus divided. A scrambler scrambles the data frame thus encoded using a reproducible pseudo-random signal. A serializer converts the output of the scrambler into serial data. A transmitter transmits the serial data to the in-vehicle controller via a cable.Type: ApplicationFiled: March 3, 2020Publication date: June 16, 2022Applicant: KOITO MANUFACTURING CO., LTD.Inventor: Hiroto TAHARA
