13 things you need to know in tech today

Happy friday! This is your daily technical summary, via the DGiT Daily newsletter, before Tuesday 2 April 2019!

1. Low light is now a highlight for (some) smartphone cameras & # 39; s

One of the key benefits of the launch of Google Pixel 3 was the Night Sight mode, which offers a step-by-step improvement in camera quality in low light.

  • Google rolled out that technology to its other Pixel phones, including the Pixel 2 and even the original Pixel, which indicates software progress rather than new hardware.
  • Developers and hackers have imported the Google Camera app (XDA), as we mentioned earlier.
  • This dramatically improves night and photo in low light using Night Sight on some devices such as OnePlus, Motorola, Xiaomi and others, although the quality is not as good as the Pixel
  • That is no big surprise given the way in which Google calibrates and optimizes the Pixel.

But Huawei & # 39; s P30 Pro seems to make another big step forward with low-light photography, this time combining software and hardware, as you'll see:

It also does not require the long exposure time required by Google's night view mode and shaves a few seconds out of the total time to take a picture in low light.

What is happening here?

  • Bogdan Petrovan of Android Authority described Huawei's Night Mode as "insanely skilled", with usable shots in almost complete darkness.
  • Other phones would spit out a black image and even compared to the Night Sight setup of the Pixel it looks like a clear winner.
  • The trick is the P30 Pro with a new type of image sensor filter cartridge in smartphones.
  • To get the technical, and not the red, green, green, blue (RGGB) Bayer Pattern filter array that we usually see with camera sensors, the P30 Pro uses a red, yellow, yellow, blue (RYYB) filter cartridge. And a slightly wider f / 1.6 aperture, to let in more light.
  • I asked AA & # 39; s chief technical writer, Robert Triggs, to further explain why Huawei made this choice, and what compromises this would make:
  • "In the RYB setup, the yellow pixel captures more light data, so the P30 Pro can offer that much better performance in low light," Rob wrote.
  • "The interaction is that you don't have a green pixel, so you have to do some nice math to extract the green color information from the yellow. In some situations, the algorithm can overwrite the green info."
  • In short: you offer a small amount of color accuracy and distortion in exchange for more light information.
  • Rob has further explained in this post: Huawei P30 camera & # 39; s: all new technical data explained, regarding all technical details.

The problem:

  • All of this poses a problem for Samsung and Apple: the latest Samsung S10 devices cannot compete and the iPhone is also a mile back.
  • It may be that Google and even Apple can surpass Huawei with their upcoming devices later this year, but for now the P30 Pro has a big head start.
