Speed by Zoom: When this function is turned “ON”, at the time when
the zoom-in/zoom out is beginning or it is about to reach the zoom-
in/zoom-out limit or users want to stop zooming in/zooming out, the
zoom-in/zoom-out speed of the camera lens will be reduced linearly.
When this function is turned “OFF”, the zoom-in/zoom-out speed will be
consistent no matter when the camera zoom-in is started or stopped.
