本发明有效解决了在逆光拍照时不能自动检测逆光状态并自动对图像中主体对象的亮度进行补偿的问题。
This invention efficiently solves the problem of being unable to auto-test the backlighting state and auto-equalize the luminance of the main object in the image when backlighting shooting.
但是，因为这些主星的亮度相对偏淡，所以它们可能没有足够的高温令系外行星的主体结构气化。
Yet because the host stars are relatively dim, they may not have been hot enough to boil away the building blocks of exoplanets.
