看到流出图是单镜本觉得不妙，后来找了一下最近的gcam更新
发现google p3 好像在蕴育另一种黑科技，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社先大量喂图训练，利用ML跟VC运算去猜测远物，强化数位远焦成像。
不过录影上是否能这么威就是问号。
