On December 28, Samsung recently released two new sensors designed for AR VR headsets and smartphones: 3D TOF time-of-flight sensor Isocell Vizion 63D and Global Shutter sensor Isocell Vizion 931. Both sensors are currently being tested by device manufacturers and brands around the world, and are expected to be used in future products such as Samsung's MR mixed reality headsets.
The sensor ISOCELL VIZION 63D, which integrates a depth-sensing hardware ISP, reduces power consumption by 40% compared to conventional components
According to the presentation, the 3D TOF sensor Isocell Vizion 63D has a size of 1 64 inches, with 3With 5 m size pixels, it can shoot VGA (640 480) resolution** and capture images in QVGA (320 240) quality and 30fps. The element calculates the phase difference between the emitted and reflected light and provides a 3D understanding of the surrounding environment, making it ideal for secure facial recognition on devices such as AR VR headsets, robots, and smartphones.
It is also the industry's first sensor to integrate a depth-sensing hardware ISP image signal processor to acquire and process depth information without the need for additional computing chips. Compared to traditional sensors such as Samsung's Isocell Vizion 33D, the Isocell Vizion 63D consumes 40% less power.
The ISOCELL Vizion 63D is also equipped with Backside Scattering Technology (BST), which achieves the highest quantum efficiency and light absorption (38% at 940nm IR wavelength), which helps reduce noise and motion blur for improved clarity. The 63D TOF supports both a shorter, high-resolution flood mode and a low-resolution, longer-range spot mode. It increases the depth and distance measurement range from 5 meters to 10 meters with the previous generation of sensors.
Capture the entire scene like a human eye, delivering the industry's highest level of quantum efficiency
Traditionally, a conventional rolling shutter sensor scans the scene progressively from top to bottom, which can lead to a jello effect of motion blur. Samsung's global shutter sensor, the ISOCELL Vizion 931, can capture the entire scene at once, just like the human eye, to obtain a clear and undistorted image.
With a resolution of 640 640 pixels, the ISOCELL Vizion 931 is suitable for face and gesture detection in XR headsets, in addition to applications such as iris recognition and eye tracking. It offers the industry's highest level of quantum efficiency, delivering 60% quantum efficiency at 850nm infrared wavelength.
At the same time, the device supports FDTI deep groove isolation pixel technology, which effectively reduces the cross-interference of light between pixels, improves the performance of the image sensor, and shows the ability of high image quality in low light source environments. The Isocell Vizion 931 is ideal for AR VR headsets, drones, and robots. Predictably, we'll soon be able to see the component on Samsung's upcoming MR headset.
