中文摘要:
      人工智能技术的发展促使人们通过智能手机进行交互,因此设置适宜的手机屏幕亮度对于保护人眼健康至关重要。针对该问题,文中结合人眼视觉特性对手机屏幕自适应亮度调节算法进行了优化。首先,设计了两款测量工具来采集和分析相关的数据。然后,采用主观评价的方法对室内外不同环境照度条件下的手机亮度值进行了研究。实验结果显示,用户理想的手机屏幕亮度远远低于现有自动亮度调节下的手机屏幕亮度。最后,根据用户的体验和人体视觉的特性设计了相应的算法,并对算法进行了评估。
英文摘要:
      The development of artificial intelligence technology prompts people to interact with each other by smartphone,therefore,it is significant to set suitable phone screen brightness for keeping eyes healthy.In light of this problem,this paper optimized the adaptive adjustment algorithm of mobile phone screen brightness by combining the human visual characteristics.Firstly,this paper designed two measurement tools to collect and analyze relevant data.Then,this paper made use of the method of subjective evaluation to study the smartphone brightness under different indoor and outdoor illumination conditions.The experimental results show that the ideal mobile phone screen brightness is much lower than the screen brightness of mobile phones obtained by the existing automatic brightness adjustment.At last,according to users’ experience and the characteristics of human vision,this paper designed and evaluated corresponding algorithm.
