The motion of a gyroscope rotates in space on all three axes. In this case, it determines the direction in which you are moving your phone.
Image stabilisation helps to prevent blur caused by camera shake. You should consider getting a lens with image stabilisation if you capture many zoomed-in shots or shoot without a tripod.
Timelapse is a technique where the frequency at which film frames are captured is set at specific intervals. The camera captures hundreds or thousands of photos in succession and then the result is played back, creating a stunning movie. One significant drawback of this type of photography is its relatively fast shutter wear compared to the lens, especially when shooting at close range. These days, however, you are far more likely to find a camera with a preview LCD display instead.
A gimbal is a special device that keeps the camera stable when taking photos and videos by eliminating small jolts and tilts. The camera remains in a stabilised position on three axes, allowing you to take crisp photos or smooth videos during flight.
