A mighty Google Pixel night sight camera has just got released by Google for the Google Pixel phones. And in the title why we wrote ‘A superman camera’? That’s because of this >

We all know that Google Pixel 3’s camera is right now the world’s best smartphone camera. And after seeing the image at the top, we can assure you that, Google Pixel night sight camera has got better than the best!

After releasing the Pixel 3 at October, Google hinted a performance boost of its nigh sight camera mode. And then on November 14, Google has extended its lead in the camera section by announcing a revolutionary new camera mode, the Night Sight. Google’s Night Sight camera is nothing but a moment combining several moments but in a complex mode. At a normal look, it might look like a normal long-exposure mode image. But what Google made here is more versatile, more intelligent and more complex long-exposure shot. What we’ve done in the past was to use a tripod or hold our hand as steady as possible to take a nigh shot. We did that in order to have a clear image by letting the camera sensor catch more light for a longer period of time in the dark situation. Here Google did the same fundamental but in a higher dimension. Google Night Sight camera is doing the same thing by taking a burst of consecutive frames and then reassembling them into a single image using Google’s algorithm magic. Such like an HDR+, but this time this mode is the boss of all HDR+.

Even before a shot is taken, after opening the camera app at night, the camera app has already done a ton of measurements and calculations! Using Google’s so-called Motion metering, Google Pixel night sight camera considers its own movement, the movements of the subject on the frame and the amount of light the scene has. And doing all these measurements, Google Pixel camera calculates how many exposures it would need and for how much time it would take it. At the maximum level, night sight camera would need to take up to 6 seconds and 15 frames to capture and combine them into a single image. That means Google has updated its algorithm limiting the camera to take one second per exposure if the phone is standing still. And if the phone is handheld, then it would take one-third of a second. So the equation goes to, you can take 6 one second exposure if you place the phone on a tripod and 15 exposures if you are holding the phone. And all those exposures will result in a single photo.

Judging the White Balance is another critical issue for the camera sensor. And for the Google Pixel Night Sight, it is a continuous learning process. Google has implemented a brand new algorithm into the Night Sight that has been trained to discard and discount the tints and grains that occur by unnatural light. Technically the software looks at how the log-chrominance histogram of each photo shifts with varying tints. And Google calls it Fast Fourier Color Constancy (FFCC). Here is a quote from a previously published White Paper on the FFCC summarizing the core technique:

Tinting an image affects the image’s histogram only by a translation in log chrominance space. This observation enables our convolutional approach to color correction, in which our algorithm learns to localize a histogram in this 2D space.

The Google Pixel Night Sight camera is only limited and suitable for night time or low-light situation only. Google has released this camera update for Pixel 3, Pixel 3 XL and Pixel 2 series. Even Google’s 1st gen pixel is also having this camera boosting update. But the sad part for the older Pixel model owners is, this night sight camera update will not work as it should be because of the hardware issue. Not having an optical image stabilization is a big cause of that performance drop. But Google Pixel 3 and Pixel 2 owners will have full juice out of it. Now less talking and be amazed seeing the comparison images taken with Night Sight camera.
