Controlling brightness of light sources used for data transmission

摘要

A method includes receiving a transmitted code via visible light communication from a light source. The transmitted code is decoded using a translation table. The translation table indicates raw data corresponding to the transmitted code as well as a duty cycle corresponding to the transmitted code.

1. A method comprising:
receiving a transmitted code via visible light communication from a light source; and decoding the transmitted code using a translation table,wherein each entry in the translation table has a unique code associated with raw data and with a duty cycle, and an overall desired duty cycle is based on a selected first duty cycle for a first piece of data and a subsequently selected second duty cycle for a second piece of data that is added after transmission of the first piece of data to approximate a desired brightness level.
