In 2020, iPhones are said to improve significantly above previous iPhones. Rumor has it that the new iPhones would use sensor-shift image stabilization technology instead of the conventional stabilization of the optics.
Smartphones generally are reliant on optical image stabilization whereas the upcoming phones are expected to come with sensor-shift stabilization where the sensor itself is moving to counteract shakes instead of the optics. The reason for the upgrade whether its for better camera performance, image quality or it’s looking to save up some precious space and thus reduce the camera bumps on the back. The reasons could also be cost-related.
We should find out more soon, and when we do it will be revealed here.
