Abstract

Reflection interference control can comprise: determining, according to identification information comprised in a light signal from a reflection surface to a field of view of a user, that a reflection interference phenomenon exists on the reflection surface; and generating a control signal for lowering the level of the reflection interference. For example, by using the characteristic that a light source identifier is modulated in a light signal transmitted by a light source in the existing wireless optical communication, whether a reflection interference phenomenon exists can be determined according to identification information comprised in a light signal received by a field of view of a user from a reflection surface, and reflection interference is automatically controlled if it is determined that the reflection interference phenomenon exists, which is simple and quick and does not require user intervention.

Description

technical field [0001] The present application relates to the technical field of wireless optical communication, and in particular to a reflection interference control method and a control device. Background technique [0002] When users watch visual content (for example, reading, watching video content, looking in a mirror), they are often disturbed by light signals from other light sources in their environment. For example, in figure 1 In the shown scene, when watching content displayed on the display screen of a terminal device (eg, mobile phone, laptop, TV) 110 , the light emitted by the light source 120 is reflected from the display screen surface of the device 110 to the user's field of view. When the intensity of the light signal of the light source 120 reaches a certain level, it will interfere with the viewing of the user. Contents of the invention [0003] The purpose of this application is to provide a solution for reducing reflection interference. [0004] I...
