Apple denies reports that Animoji doesn’t require iPhone X’s TrueDepth camera -蘋果否認Animoji不需要iPhone X的TrueDepth camera However, as Brownlee later tweeted, Animoji actually uses data from the infrared camera and depth sensors for better accuracy. “Apple told me they wouldn’t want a worse Animoji experience for other iPhones without those sensors,” he added. So how come then that Animoji can sometimes seem like it’s working normally even when parts of the True Depth camera are covered up? And why if you cover the RGB camera, it stops. Business Insider offers a viable explanation: Apple’s True Depth camera doesn’t take a 3D reading continuously. Instead, it takes measurements at set intervals, or what’s called a sampling rate, although Apple didn’t comment on the specific sampling rate. When Animoji seem to remain responsive even after the IR sensor is covered, the system could still be going off of an earlier reading. The first depth reading is taken when the user starts Animoji. In other words, if you cover up the left side of the notch where the infrared camera is located before using Animoji, performance will be degraded. iMore acknowledged as much, saying the infrared system on the TrueDepth camera fires periodically to update a crude depth mask while the RGB camera persistently tracks and matches facial movement and expressions. -蘋果認為少了TrueDepth camera，Animoji的辨識會變得很糟糕。 -只靠鏡頭就能辨識是因為有先紅外線掃過臉才遮住紅外線，讓只有鏡頭也能運作。來源： http://www.idownloadblog.com/2017/11/15/apple-denies-reports-that-animoji-doesnt-require-iphone-xs-truedepth-camera/ https://goo.gl/8aJU1F 不過我剛剛試從解鎖到進入Animoji都遮住紅外線，一樣能辨識表情。 BTW, Animoji 在低光源的地方還會不堪使用或停擺，我看基本上..就是用鏡頭就可以吧XD -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 218.161.47.131 ※ 文章網址: https://www.ptt.cc/bbs/iOS/M.1510799655.A.5FF.html
