S402:根据所述三轴姿态角速度,得到所述拍摄设备的抖动程度。
其中,一种可能的实现方式:

在进行拍摄参数的调整过程中,需要满足前述的经验曝光方程。
一种可能的实现方式:所述拍摄参数包括:快门速度和感光度。
曝光策略为:根据所述拍摄设备的抖动程度,调小所述快门速度,调大感光度,抖动程度越大,快门速度越小,感光度越大。
另一种可能的实现方式:所述拍摄参数包括:快门速度和光圈值。

可选地,由于感光度会影响色噪,增大感光度会引入更多的噪声,影响画面质量,因此,在快门速度、光圈值和感光度都可调的情况下,优先调快门速度和光圈值,最后调感光度。
在上述各种可能的实现方式中,具体调小或者调大的数值根据抖动程度确定。

可选地,预设阈值可以根据经验值确定,例如:可以确定对拍摄的画面的质量影响不大时,最大的抖动程度为预设阈值。
可选地,由于感光度会影响色噪,增大感光度会引入更多的噪声,影响画面质量,因此,在快门速度、光圈值和感光度都可调的情况下,优先调快门速度和光圈值,最后调感光度。
