M.Levoy離開Pixel團隊可能原因 - 手機討論

最近剛好看到這篇文章，內容是levoy離開pixel團隊後的cis方向。

從他對傳感器的看法，也許 可以了解為何最終離開pixel。

簡單來說 levoy想要朝bigger sensor，拉升snr，不太認同QB的做法。

G社當時可能想要利用ai克服QB猜色，然後就分手了。

期待新(***?)團隊的成果。


When you say 96 is a bad idea — much like we had megahertz wars for a while,
we did have a megapixel war for a minute.
#############
As I said, the signal to noise ratio is basically a matter of the total
sensor size. If you want to put 96 megapixels and you can’t squeeze a larger
sensor physically into the form factor of the phone, then you have to make
the pixels smaller, and you end up close to the diffraction limit and those
pixels end up worse. They are noisier. It’s just not clear how much
advantage you get.


Do you think any of the pixel bending or Quad Bayer techniques — because the
48-megapixel cameras, they still spit out a 12-megapixel photo by default —
do you think those help?
############
That remains to be seen. If you have four reds, four greens, and four blues,
that makes de-mosaicing — interpolating the reds, greens, and blues that you
don’t see — harder. Those Quad Bayer sensors have been subject to spatial
aliasing artifacts of one kind or another, zippering along rows or columns.
Whether that can really be adequately solved remains to be seen.
