Generally it includes three steps: lightintensity measurement, scenario analysis and exposure compensation. And auto-exposure has optics-implemented way and electronic-implemented way.
一般包括光强测量、场景分析和曝光补偿等三个步骤，可以用光学和电子学两种方式来实现。

The maximum photosynthetic rate, light saturation point, lightcompensation point and dark respiration were smaller under weak lightintensity than those under strong light intensity.
弱光生境中秋茄幼苗的最大光合速率、光饱和点、光补偿点和暗呼吸速率较低。

The lightcompensation point (LCP) and light saturation point (LSP) of A. oxyphyIla improved with light intensity enhancing.
