Samsung’s 50MP GN1 camera sensor promises faster autofocus



Samsung has announced a new camera sensor for phones that potentially offers faster autofocus and better low-light photography.

The Samsung Isocell GN1 is a 50-megapixel sensor with 1.2μm-sized pixels – larger than usual. This, combined with Dual Pixel and Tetracell technology (for the first time in a single Samsung sensor), allows for more sensitive light capture and “DSLR-style autofocus speeds”.

Tetracell technology effectively improves a pixel’s ability to capture and process more light by binning four pixel signals into one. It therefore increases the pixel size to 2.4μm and enables much brighter 12.5-megapixel images – a quarter of the usual resolution but better low-light pics.

Dual Pixel technology utilises two photodiodes sitting side-by-side in a single pixel, with each able to receive light from different angles for phase detection. That means, when all pixels are deployed for focusing, it snaps into focus much more quickly that previous Samsung camera sensors.

As well as the two technologies, the GN1 comes with Smart-ISO technology for auto ISO selection, real-time HDR, and electronic image stabilisation.

It supports video recording in up to 8K 30fps.

The chip, which is seen as a direct rival to Sony‘s IMX689 alternative – found in the OnePlus 8 Pro and a few other recent handsets – will be going into mass production this month. We should see it in phones later this year.

DJI presents Mavic Air 2, now with 48 Megapixel sensor and 8K 240 fps


The famous drone manufacturer DJI officially unveiled the new Mavic Air 2 , a light, foldable model with excellent technical characteristics. The drone weighs 570 grams (in flight order) and this makes it heavier than the model it replaces but the extra weight is certainly justified by the improved technical specifications and a more solid construction.

, the Mavic Air 2 is also equipped with APAS 3.0 (a sort of 3D mapping to also recognize obstacles in height) and a system called ADS-B

First of all, the autonomy is now 34 minutes thanks to the new engines, improved aerodynamics and better battery. Another novelty is certainly the 1/2″ sensor with 48 MP resolution and QuadBayer scheme that takes 12MP photos of great quality thanks to the pixel-binning technique but can also capture at 48MP in High resolution mode if the environment has a good brightness Although the photographic aspect is important, the main use is certainly the one related to the video world.

Here too important news: the maximum video resolution rises to 4K @ 60p with a bitrate of 120Mbps, but it is also possible to record in FullHD up to at 240 frames per second or create Hyperlapse in 8K format.

 

video resolution of Mavic Air 2  rises to 4K @ 60p with a bitrate of 120Mbps, but it is also possible to record in FullHD up to at 240 frames per second

 

There are many new intelligent modes such as HDR photo (take up to 7 photos with different exposure to automatically combine them) or Hyperlight mode (a sort of night mode that, like for smartphones, combines various photos with different shutter speeds and different ISO) and finally the automatic recognition of the scenes which is grateful to automatically adapt to the types of framing (sunset, snow, grass etc …) to optimize colors and details.

All automatic flight mode systems have also been updated, for example there is Active Track 3.0 (automatic tracking system), Point of Interest 3.0 and Spotlight 2.0 which allow you to perform complex shots in total autonomy. Improved drone safety with obstacle detection sensors on the front and rear, sensors and lights on the bottom for safe landings. In addition, the Mavic Air 2 is also equipped with APAS 3.0 (a sort of 3D mapping to also recognize obstacles in height) and a system called ADS-B (Automatic Dependent Surveillance-Broadcast) which is able to detect if there are other drones nearby and then report them to the operator (well before you get to hear them).

As a last novelty we point out the presence of the OcuSync 2.0 system which gives the Mavic Air 2 a range of action of 10Km. The new Mavic Air 2 is already on sale on the DJI website starting from € 849 for the normal version or € 1049 for the Fly More Combo which includes an additional 6 propellers, two batteries, and a multiple charger. As soon as the first offers come out, we will publish them on our Telegram channel.
