蘋果最新專利能阻止iPhone在特定場所隨意拍照
Many artists and comedians politely ask the crowd to refrain from snapping pictures and shooting videos during their performance – only to be ignored once the show starts.
許多藝術家和喜劇演員都會禮貌地請求觀衆，不要在他們表演的時候拍照或者錄像--不過一旦演出開始之後，觀衆們還是會這樣做。Apple's latest patent could be the solution, disabling the use of recording and photography features inside concert halls.
蘋果公司最新的一項專利可能會解決這一問題，能夠在音樂大廳裏禁止使用拍照和錄像等功能。Using infrared data transmissions, venues would emit a signal that would hit every iPhone, preventing users from taking pictures and recording videos of the stage.
通過使用紅外線數據傳輸技術，演出場館將會向現場的每一臺iPhone都發送一個信號，使得iPhone的用戶暫時不能使用手機的拍照和攝像功能。
'In some embodiments, a transmitter can be located in areas where capturing pictures and videos is prohibited and the transmitters can generate infrared signals with encoded data that includes commands temporarily disabling recording functions,' reads the patent published by the United States Patent and Trademark Office.
根據美國專利和商標局公佈的專利說明中，我們可以讀到：“在某些實例中，紅外線發射器可以安放在某些禁止拍照和攝像的地方，而且這個發射器能夠產生帶有編碼數據的紅外信號，信號中包含的指令將使得觀衆暫時不能使用錄像和拍照功能。”The new technology would allow event organizers and performers to set up a device on the stage, push a button and instantly hinder the audience from recording their favorite song or snapping an image of the performer for their Instagram.
要使用這一新技術，活動主辦方和表演者要在舞臺上安裝一臺設備，按下按鈕的瞬間，觀衆就不能錄下他們喜歡的歌曲，也不能拍下表演者的照片發到Instagram上去了。When switched on, the device would shoot out the signal and every iPhone in the audience would display 'recording disabled' on the screen – but only if users attempt to take pictures or shoot a video at something you shouldn't.
一旦開始運轉，這臺設備就會發出信號，現場觀衆手中iPhone的屏幕上將出現“不能攝像”的字樣--但也只有在用戶們企圖拍攝那些不允許被拍攝的東西的時候纔會這樣。For example, it will be disabled if you try to take a picture of the performer on stage but not if you are taking a picture of your friend dancing to the music.
舉例來說，如果你打算拍一張舞臺上表演者的照片的話，你的手機就不能使用拍照功能了，但是如果你想拍一張你的朋友隨着音樂跳起來的照片的話，那就沒問題。This is because infrared is directional, meaning the receiver that is on stage can only hit the iPhones that are pointed directly at the device.
這一情況是因爲紅外信號是定向的，這就意味着只有當iPhone正對着舞臺上的設備的時候，發出的信號才能夠傳送到iPhone中去。Another option of this technology would either add a watermark or blur effect to images snapped during the event – in a bid to discourage people from sharing them online.
這項技術還有另外一個備選方案，那就是讓觀衆們在活動現場拍攝的照片上帶有水印或者模糊效果--以此來勸阻人們不要在網上傳播這些圖片。
