Apple: vibration can affect iPhone camera performance

Apple has warned iPhone users that prolonged exposure to certain vibrations can affect the device’s camera performance by interfering with many of its more sensitive components.

MacRumors spotted the company’s disclosure of this issue in a support article published on September 10. Apple says vibration can affect two specific aspects of the iPhone’s camera system: optical image stabilization (OIS) and closed-loop autofocus (AF).

The OIS adjusts the camera lens in response to movement to capture the clearest image possible even if the device is not perfectly still. Closed-loop autofocus, on the other hand, is supposed to “preserve sharp focus in still images, videos and panoramas.” Both features are essential for iPhone photography.

Apple said the OIS relies on the iPhone’s gyroscope to determine how the camera lens should be adjusted. Closed-loop AF uses magnetic sensors to “measure the effects of gravity and vibration and determine the position of the lens so that the compensating motion can be fine-tuned.”

“IPhone’s OIS and Closed Loop AF systems are built to last,” Apple said. “However, as is the case with many consumer electronics devices that include systems like OIS, long-term direct exposure to high-amplitude vibration in certain frequency ranges can degrade the performance of these systems and cause serious injury. reduced image quality for photos and videos. It is recommended to avoid exposing your iPhone to prolonged high-amplitude vibrations. “

The company said it does not recommend connecting an iPhone to “motorcycles with high power or high volume motors” because of this potential disruption of the device’s camera. Even people driving low powered mopeds or scooters have been advised to use vibration damping mounts.

Apple has stated that OIS is found in iPhone 6 Plus, 6s Plus and later, with the exception of specific lenses on iPhone 7 Plus, iPhone 8 Plus, and iPhone 11. AF closed loop is found on the iPhone XS and later. . Both systems are also found in the second generation iPhone SE.
