看到流出圖是單鏡本覺得不妙，後來找了一下最近的gcam更新
發現google p3 好像在蘊育另一種黑科技，RAISR。
RAISR, short for Rapid and Accurate Image Super Resolution, takes a different
approach from ordinary digital zoom. It uses a machine learning system
trained on real photos to make more intelligent guesses at filling in details.
The change came with a Pixel 2 update to take advantage of the phone's Pixel
Visual Engine, a custom chip that accelerates some processing tasks. That
includes running artificial-intelligence software and rapidly merging
multiple raw photos into a single "HDR+" photo that avoids dark shadows and
blown-out highlights.
所以G社先大量餵圖訓練，利用ML跟VC運算去猜測遠物，強化數位遠焦成像。
不過錄影上是否能這麼威就是問號。
