EIS
Corrects the device shaking with difference comparison algorithm and
improves the image clarity, effectively solves the picture shaking
problem.
Optical Dejitering
The lens vibration is sensed by the gyroscope sensor, and the
corresponding compensation is calculated using the intelligent
anti-shake algorithm. The movable parts inside the lens are driven to
offset the vibration, which greatly reduces blurring of the image caused
by the vibration.
Picture Freeze
When you call a preset, the image displays the preset location, not the
rotation image.
