Research And Application Of Blue Light Hazard Classification Of Video Source

Light is closely related to human daily life.With the discovery of photoreceptor ganglion cells(ip RGC),people pay more and more attention to the quality of light sources,and photobiological safety has gradually become an important parameter to examine the quality of light sources.Photobiological safety includes visual effects,which mainly refers to the harm caused by light sources to human vision;the other type is non-visual effects,that is,light affects the endocrine system of the human body,thereby affecting the normal circadian rhythm.At present,the short video industry is developing rapidly,which has also caused some problems,such as: whether watching short videos using artificial light sources such as mobile phones and computers for a long time will cause blue light harm to the human eye,and whether there are differences in the degree of blue light harm generated by different video sources,how to quantify the extent of the impact of blue light in video sources on the human body,etc.In order to solve the above problems,this paper mainly focuses on two aspects.Firstly,animal experiments are carried out to explore the impact of light sources with different spectral distributions such as blue light on animal rhythms;secondly,by developing the software for detecting blue light hazard of video source and realizing its function,a blue light hazard assessment method of video source is finally constructed.The main content and research results of this paper are as follows:(1)Introduced the mechanism of blue light hazard to visual effects and non-visual effects.Through animal experiments,the effects of light sources with different spectral distributions on the laying phase of animals were briefly described.(2)Designed and developed a video source blue light content detection system,which divided the overall software design into three parts: front-end interface,data interaction platform and back-end algorithm.Front-end interface is based on C#Win Form development,used for human-machine data interaction,the main modules are registration and login module,task command module,parameter setting module,etc.The function of the data interaction platform is to facilitate the data interaction between the front and back ends,and its function is mainly to obtain the command of the front and back ends,record the system processing information and so on.The backend algorithm is implemented by Python programming language,which is mainly responsible for data processing and sends the processed data to the interactive platform.(3)The overall function test of the software is carried out.After setting a video source with special blue light content and passing the system detection,the conclusion is reached compared with the theoretical value: the measurement error of the video source blue light detection system is less than ±1%,and the system can basically achieve the detection of blue light content in the video source.
