  • Information transmission system transmitting visible optical signal received by video camera
    Patent number: 10985840
    Abstract: An information transmitter apparatus for use in an information transmission system is provided, where the information transmission system includes the information transmitter apparatus and an information receiver apparatus. The information transmitter apparatus transmits a surface-shaped visible light signal using a light source, where the visible light signal is modulated according to a modulated signal modulated using a plurality of respective-order carriers different from each other, and the respective-order carriers has a fundamental frequency and multiple frequencies of a frame output signal of a video camera of rolling shutter system provided in an information receiver apparatus. The information receiver apparatus receives the visible light signal using the video camera.
