ONDECEMBER 20 "GOOGLE PIXEL 3 AND COMPUTATIONAL PHOTOGRAPHY: HOW SOFTWARE IS DRIVING THIS" Google Pixel 3 and computational photography: How software is driving this Google Pixel 3 relies on computational photography and overall software driven approach to ensure the best possible results. There is a general move towards software-defined camera on smartphones, rather than just relying on fixed hardware, according to Marc Levoy, distinguished engineer at Google and currently leading the team responsible for modes like HDR+, portrait mode on the Pixel smartphones.

In an interaction via a video-conference call, Levoy said the trend in camera software was around combining bursts of frames, or what is called computational photography. Google is not the only player relying on computational photography, so is Apple with the iPhone XS, iPhone XR. Computational photography on smartphones essentially combines a number of frames at various exposure levels to ensure the best possible result for a photograph. “There is also a move towards machine learning, which is replacing traditional algorithm.

In machine learning you have better training data, which results in better accuracy on the tasks,” Levoy explained. With Pixel phones, Google has shown that smartphone photography does not really need a lot of extra hardware in order to deliver excellent results. The Pixel 3, like the Pixel 2, continues with a single rear camera, which also supports Portrait mode.

What is this year is that Google had added features like Super Zoom, Night Sight mode, in order to improve photography. However, Levoy does point out that just because software is improving when it comes to taking better photos, it means hardware will be irrelevant. “The hardware is separate from computational photography.

Yes, it will always matter. For instance, the aperture will control how much SuperZoom you can get. If the lenses used are not good, there will be aberrations with the software. Optics do matter,” he said on the subject. On Night Sight mode, Levoy explained the camera captures up to 15 frames after the shutter is pressed.

However, Night Sight also requires a user to be extra still while taking a picture. “The exposure really varies on how still you are standing. If you are very still, or put the phone on a tripod, it will lengthen the exposure,” he explained.

On the 15-frame capture, Levoy said this was an arbitrary choice of number, but if the camera detects that the user is very still or the phone is on a tripod, it will reduce the number of frames, and instead increase the exposure length of each shot. Of course, this also means that the final image takes that extra few seconds to be processed and shown to the user. “Night Sight is also taking into account motion metering or movement in the photo in order to ensure the best possible result,” he pointed out. Levoy also mentioned that Night Sight was a fairly late development for the Pixel 3 phones.

Officially, the feature was rolled out nearly one month after the Pixel 3 launch.
