While the Google Pixel 5 is likely to be an upgrade of the Pixel 4 in many ways, one thing that may not change significantly is the camera hardware, as it is rumored to be using the same 12.2 megapixel main sensor as its predecessor. and now we have a good idea why.
Speaking to The Verge, Marc Levoy (a former Google engineer who led the team that developed computer photography for Pixel phones) explained that hardware changes result in falling returns and, in some cases, come with problems of their own.
Levoy said, “Because of the falling returns due to the laws of physics, I don̵
More pixels, more problems
He also got more specific. On the subject of increasing the number of pixels, he explained (using the example of 96 MP): “I don’t know that it is a good idea to go to 96 megapixels.
“If you want to use 96 megapixels and you can’t physically squeeze a larger sensor into the phone’s form factor, you have to shrink the pixels and you end up close to the diffraction limit and those pixels get worse. They are louder. It’s just not clear how much benefit you are getting. “
So the problem there is with the form factor of the phones – make them thicker and you might get some benefit, but Levoy notes that Nokia tried this and was not commercially successful.
Another option is to use pixel binning, in which the data from several pixels are combined into one. We’ve seen this on a number of phones, such as the OnePlus 8 Pro, which has a 48-megapixel sensor but combines four pixels by default for 12-megapixel shots.
However, Levoy notes that these sensors tend to leave visual artifacts in images and concludes that it remains to be seen whether this can really be adequately resolved.
While Levoy doesn’t confirm rumors that Google is sticking to the same sensor, it could make sense for the company. That doesn’t mean the Pixel 5 doesn’t have camera enhancements, however, as the software still has room for improvement.
We should find out shortly which camera the Google Pixel 5 has as it is said to be announced in late September or early October.
