最近刚好看到这篇文章,内容是levoy离开pixel团队后的cis方向。
从他对传感器的看法,也许 可以了解为何最终离开pixel。
简单来说 levoy想要朝bigger sensor,拉升snr,不太认同QB的做法。
G社当时可能想要利用ai克服QB猜色,然后就分手了。
期待新(***?)团队的成果。
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.
