Patent ID: 10110303

Abstract:
Embodiments of the present application disclose various light-communication sending methods and apparatus, various light-communication receiving methods and apparatus, and various light communication systems. A light-communication sending method comprises: acquiring a first region of an image; determining, according to the first region, information about density distribution of communication information that is to be modulated to light emitted by a light source; and controlling the light source to display the image, and during displaying of the image, modulating, according to the information about the density distribution of the communication information, the communication information to the light emitted by the light source. A light-communication receiving method comprises: acquiring a first region of an image; adjusting pixel density distribution of an image sensor according to the first region; and capturing the image by using the adjusted image sensor, and during capturing of the image, receiving communication information modulated by a transmit end to light emitted by a light source that displays the image. The present application helps implement capturing of an image of differentiated definition and receiving of differentiated communication information density by a receiver end, and improves the transmission efficiency of communication information.
