- Samsung introduced the new ISOCELL GNK photochip
- It follows on from the popular predecessor GN1
- Video recording, HDR photography and automatic focus have been improved
Smartphones are more or less finished products, for which we will probably not see fundamental changes in the foreseeable future. However, where some visible progress is still taking place is in cameras, which have to deal primarily with physical obstacles. Not only artificial intelligence helps them with this, but also new technologies, without which it simply wouldn’t be possible. Samsung, which is one of the largest manufacturers of mobile photo chips in the world, knows about this. It celebrated quite a lot of success with the 50 Mpx photo chip ISOCELL GN1, which has now received a successor.
ISOCELL GNK improves HDR and video recording
The novelty, called ISOCELL GNK, also boasts a resolution of 50 Mpx, as well as improved video recording and a greater dynamic range for photos. In terms of technical specifications, we would not find much difference between GN1 and GNK – they have the same size of 1/1.3″ and offer the same pixel size of 1.2 µm. Instead of tweaking the numbers, Samsung focused on implementing new technologies such as Dual Pixel Pro autofocus, which can focus on moving subjects faster and more accurately.
In addition, the sensor can capture images with a dynamic range of up to 120 dB and in Pro mode can take images in 14-bit RAW format. To increase dynamic range, GNK uses three different ISO modes to help reduce graphic artifacts. As for video recording, the GNK can record up to 8K resolution at 30 frames per second, while in this mode there is no significant narrowing of the field of view. At the same time, the new photo chip supports the recording of HDR videos or Full HD recordings at 240 frames per second.
Samsung unveiled a 200Mpx photo chip. It will first appear on the Galaxy S23 Ultra
For now, it is not clear which phones will be the first to receive the improved ISOCELL GNK chipset, but we won’t see the new feature in practice until next year. It is quite likely that Samsung will deploy GNK first in its models and only then will it appear in competitors.
