Apple’s novel Sensor-shift OIS in the iPhone 12 Pro Max camera

Today’s top tier smartphone cameras use a variety of techniques to produce consistently high-quality images under non-ideal conditions. One such technique is optical image stabilization (OIS), where the camera rapidly adjusts its optical path in real time to correct for a shaky hand or bumpy car during long exposures and video capture. In conventional smartphone OIS, the lens barrel is shifted laterally to keep the image static on the image sensor. With the iPhone 12 Pro Max, Apple has taken a different approach, and instead shifts the image sensor itself. Thus the name, ‘Sensor-shift’ OIS. The primary advantage of this is that the image sensor is much lighter than the lens barrel, so shifting the sensor results in more reactive and precise stabilization. Further, lens barrel-based OIS cannot correct for camera “roll” rotation, that is, when the user inadvertently twists the camera around the optical axis while shooting. […]

Further description of the Sensor-shift OIS system, along with the estimated manufacturing process and cost analysis, will be presented in the upcoming report on the iPhone 12 Pro Max Camera, stay tuned.
