Get or set the maximum (longest) auto shutter speed in the camera. In auto shutter mode, the camera could adapt its shutter speed according to the light condition. In low light environment, the shutter is getting longer. The motion blur in the video might be seen then. To avoid this situation, the shutter speed will be limited to a reasonable speed in the low light condition.
When the lighting condition is good, the setting of longest auto shutter speed does not cause any problem because the shutter speed will not reach it. A special care should be taken if the maximum auto shutter is limited to a fast speed might cause poor video quality.
The URL helps users to fine tune the auto shutter speed operating range to fit users' environment.

where it is the index of the maximum auto shutter speed in the following mapping table. The speeds in the following table were concerned to be backward compatible of maximum auto shutter speed configurations which were defined before. So, the speeds could not have the same ascending order as index.
