Have you ever attached your iPhone to a motorcycle or scooter? Apple recently released a support document warning that exposing an iPhone to strong motorcycle vibrations might cause damage to its camera.
Optical image stabilization (OIS) and closed-loop autofocus (AF), two technologies used in the iPhone, are designed to improve image quality. They counteract the effects of gravity, movement, and vibrations to avoid getting blurry photos. When an iPhone is attached to a motorcycle or scooter with a larger engine, the high-amplitude vibrations from the engine might be transmitted to the phone and affect the two systems’ performance.
Therefore, Apple recommends that it is better not to mount iPhones to a motorcycle or scooter to avoid the problem.
你曾經把你的iPhone手機,架在重型打檔車、或是一般機車的手機架上嗎?最近,蘋果公司發布了一份技術支援文件,警示使用者如果iPhone受到機車強烈震動的影響,長期下來可能會對它的相機造成損害。
光學防手震(optical image stabilization,OIS)及自動對焦(closed-loop autofocus,AF),這兩項使用在iPhone手機上的功能,是設計用來提升影像品質的技術。這兩種技術透過在拍照時抵銷重力、移動、與震動的影響,來避免拍出模糊的照片。當iPhone被架在大排氣量引擎的打檔車、或機車上時,引擎所產生的劇烈幅度震動,可能會一路傳到手機上,對這兩種功能造成損害,進而影響拍照或錄影的品質。小排氣量或小動力引擎,相較之下震動會較小,損害也會小一些,但仍舊會影響。
因此,蘋果公司建議,若想避免這個狀況,最好是不要將iPhone裝在機車支架上。
expose 是「曝光、露出」的意思,意指從原先遮蔽的情況中顯露出來,也可以抽象地指「揭露、揭發(某件事、某個消息)」。而expose to則是「暴露在不好或危險等負面的情況下、處於險境中」的意思。
例句:
People who have been exposed to large amounts of radiation are more likely to get sick.
暴露在大量輻射照射下的人比較容易生病。
