AI models are decision-making algorithms which are skilled by way of a dataset to use to sure duties, whereas NPUs are chips designed particularly to course of such algorithms.

Figure 1: Samsung cameras with AI software

Figure 1 shows that the Samsung has utilized roughly 60 new AI fashions run by the neural processing unit (NPU) to optimize the features of the Galaxy S22 Ultra smartphone digicam, an organization govt mentioned.

This has allowed the South Korean tech large to supply digicam experiences that may fulfill informal customers with the perfect pictures doable {and professional} customers with RAW information equal to these taken on DSLR cameras, mentioned Joshua Sungdae Cho, VP and head of visible software program R&D at Samsung’s MX Business, in an interview with ZDNet.[1]

Samsung is relying on OIS and also gyroscopes using two different hardware. “This improved from the previous models from the OIS side. We improved the range of angle from 0.9 degree to 1.5 degree and also the gyroscope we use like previously 200 Hz. In the new flagships, we are using 833 Hz, so that we can, we can check the very small motion also and also in algorithm size. We measure the global path of the motion and then we smooth the motion global motions using the path planning algorithm,” he said

“Rechecking the lightness condition and we change the frame rates as seamless seamlessly and like in 24 frames per second and 15 frames per second. We also use a multi frame technology to reduce noise,” he added.

Samsung is using AI segmentation using NPU. “We use AI segmentation in real time. We seek segments. Segments mean: human body or object in real time and then we can track that object and we use that function to 3A. 3A means auto white balance, auto focus and auto exposure using tracking the object or human body,” he explained.[2]

In terms of hardware, Samsung is relying on OIS and also gyroscopes using two different hardware. “This improved from the previous models from the OIS side.

Galaxy S22 Ultra's cameras support 10x optical zoom and 100x digital zoom. It isn't the first model to do so as Samsung introduced 100x digital zoom for the first time two years ago with the Galaxy S20 Ultra, albeit to mixed reception at the time.

But with the development of the new AI models, coupled with the computational power offered by the 4nm mobile processor on the latest Galaxy S22 Ultra, Samsung was confident that the latest iteration of 100x digital zoom will impress users.[3]
