Apple iPhone: In a post on the Apple Support Forum on Friday, Cupertino has stated that exposure of iPhones to higher-amplitude vibrations, in unique to these that higher-energy motorcycle engines produce, can lead to degradation of the mobile camera functionality. The tech giant has for that reason advised against mounting the iPhone on a motorcycle due to the fact it could lead to higher-amplitude vibrations to be transferred to the phone by way of the handlebars and chassis of the motorcycle. Apple has laid out a detailed explanation about the challenge in the weblog post.
Apple stated that to avoid the pictures from acquiring blurry when the user accidentally moves though clicking the images, some models of the iPhones have been equipped with optical image stabilisation or the OIS. “OIS lets you take sharp photos even if you accidentally move the camera. With OIS, a gyroscope senses that the camera moved. To reduce image motion, and the resulting blur, the lens moves according to the angle of the gyroscope,” Cupertino stated.

Moreover, some models also have closed-loop autofocus (AF) systems that resist the effects that gravity and vibration have so that pictures can have a sharp focus in stills, panoramas as effectively as videos. “With closed-loop AF, on-board magnetic sensors measure gravity and vibration effects and determine the lens position so that the compensating motion can be set accurately,” Apple stated in the post.
Apple has stated that though the OIS and closed-loop AF systems in the iPhone have been made to be tough, just like numerous other customer electronics possessing systems like OIS, the functionality of such systems can be degraded if they have extended-term direct exposure to higher-amplitude vibrations at a particular frequency. This can, in turn, lead to lowered high quality of pictures and videos, Cupertino added, recommending that such exposure for extended periods be avoided.
“High-power or high-volume motorcycle engines generate intense high-amplitude vibrations, which are transmitted through the chassis and handlebars. It is not recommended to attach your iPhone to motorcycles with high-power or high-volume engines due to the amplitude of the vibration in certain frequency ranges that they generate,” the iPhone maker stated. It additional stated that if the iPhone is attached to automobiles that have modest-volume or electric engines – scooters and mopeds – then that can lead to comparatively reduced-amplitude vibrations. However, the business advised utilizing “a vibration dampening mount” though attaching the phone so that the threat can be lessened, but nevertheless advised against such normal attachment for prolonged periods.
As far as the OIS is concerned, iPhone 6 Plus, iPhone 6s Plus, and iPhone 7 and later models, such as iPhone SE (2nd generation) have this technologies. On the other hand, the Ultra Wide camera on iPhone 11 and later does not have OIS, nor does the Telephoto camera on iPhone 7 Plus and iPhone 8 Plus, Apple stated.
Meanwhile, iPhone XS and later models, such as iPhone SE 2020 have the closed-loop AF.
