1. 夠用 現在的手機拍照90%以上都是手機上觀看,從大多數需求來說提升畫素並沒有顯著
好處。
2. 使用者不在乎,蘋果內部肯定也調查研究過畫素多少實際上對於購買意願有多少影響,
肯定是影響沒有嚴重到需要以提升畫素數來吸引購買。就跟ram一樣,沒多少人在乎,總之
拍的好看就行。
3. 成本太高,蘋果作為一個手機行業龍頭,任何決策都會被放大檢視,可以某方面不進步
,但是絕對不能體驗上有明顯退步。要是為了增加到6400萬畫素,或是不說那麼多,2000萬
畫素,對於這幾年主打的計算攝影,在後期處理,瞬間拍攝張數,都會增加很大的計算量,
對性能要提升很大才能做到相同的水準,要是不增加計算量,提升的性能反而能用來讓畫面
有更明顯更直觀的提升,那當然優先選擇提升後期計算品質,而不是畫素數。直到後期計算
提升量到一個瓶頸,有多餘的計算量才值得來考慮提升畫素數。要是做不到,哪怕是拍完照
要多等半秒,都會帶來很多不利的影響,更不用說拍完後的容量,上傳icloud的時間等。
與其思考為什麼不提升畫素數,為什麼需要提升才是更重要的問題,高畫素可以無損變焦,
那配不同焦距的鏡頭,或是用ai升提升更高的清晰度或許是更有效率效果也更好的作法,一
張照片從按下快門到拍攝完畢中間有很多很多影響的因素,鏡頭組,ISP,像素面積,ai演
算法等等…然而其中只有畫素數能簡單用一個數字表示,對宣傳來說是更直接有效的作法,
但是對於實際的體驗還有並不是畫素提升一倍體驗就好一倍,反而可能是畫素提升了整體體
驗反而變糟,只能說對於蘋果來說,他還沒有必要透過提升畫素數來進行行銷宣傳。
