Does iphone have optical image stabilization?

IPhone 6s and previous IPhone models have no optical image stabilization function.

Up to now, models with optical image stabilization function include the following iPhone models:

iphone6plus、iphone6s plus、iphone7、iphone7plus、iphone8、iphone8 plus、iphoneX、Iphone Xs、Iphone Xs max、Iphone 1 1、Iphone 1 1 pro、Iphone 1 1 pro max、Iphone 12、Iphone 12 pro、Iphone 65444

Optical anti-shake function is a dynamic compensation structure realized by special lens or CCD element, which can minimize the image instability caused by jitter in use.

The principle is that the gyroscope in the lens detects slight motion, then transmits the signal to the microprocessor, and immediately calculates the displacement to be compensated, and then compensates through the shaking direction and displacement of the lens. Compensating lens group. So as to effectively overcome the image blur caused by camera vibration.

Several types of optical image stabilization:

Lens stabilization

The anti-shake realized by the lens group is mainly represented by Canon and Nikon, and the lens is hung by magnetic wrapping, which effectively overcomes the image blur caused by camera vibration. This is more effective for digital cameras with large zoom lenses.

Realize anti-shake

Only Konica Minolta and Pentax can achieve anti-shake through CCD. Its principle is contrary to the optical anti-shake technology of Canon and Panasonic. It relies on the floating of CCD to achieve anti-shake.

Electronic image stabilization

The so-called electronic anti-shake means that the whole anti-shake process is realized by digital processing technology without the assistance and participation of any parts. At present, electronic image stabilization is mainly achieved by improving the sensitivity (ISO) of the camera. "Natural image stabilization" and "digital image stabilization" realized by pixel compensation or other calculation methods.

Double anti-shake

The so-called "double anti-shake" is the anti-shake system of digital camera, which consists of "optical anti-shake" and "high sensitivity". Among them, "optical image stabilization" is a more complex technology, which relies on the built-in precision gyroscope and a set of movable lenses to calculate and correct the light deviation caused by hand shake to avoid blurring.
