摘　　要：针对目前市场上Android手机屏幕的背光亮度不能根据外界光线强度变化作出及时调整的问题,搭建Android的开发环境,采用代码移植方法对光线传感器进行实现,同时提出一种设置阈值的中值优化算法。实验数据分析显示,优化后的光线传感器在调节手机背光亮度上更加灵敏。For the problem that Light Sensor of Android phone on the currently market cannot adjust backlight brightness when light intensity change in the external environment , the Android development environment is built, by using the code transplant method to realize Light Sensor and thus a set of threshold value optimization algorithm are presented. The optimization results show that the optimized Light Sensor in the regulation of mobile phone backlight brightness more sensitive.
