Samsung introduces new ToF sensor and new main shutter sensor for AR/VR glasses and phones
Samsung has added two new sensors to its line ISOCELL Vizion. The first is the sensor ToF senzor which measures the distance to objects, and the second is the sensor of the main shutter.
Let's start with Samsung ISOCELL Vizion 63D. This is the first sensor in the industry with an integrated ISP for depth sensing, so it can perform the calculations on its own instead of relying on an additional chip. This reduces system consumption by up to 40% compared to the previous Vizion 33D sensor, he reports SamMobile.
The 63D can capture depth information at 320 x 240 pixels at up to 60fps, and also supports a 640 x 480 pixel mode. It is an indirect ToF sensor, which means that it measures the phase change between emitted and received light, thus achieving a more accurate measurement. This is a 1/6.4-inch sensor with 3.5µm pixels.
SamsungThe sensor supports flood and spot illumination – the former provides high resolution at a short range of 5m (16ft), while the latter extends the maximum range to 10m (33ft) with reduced resolution. The sensor is built with backscatter technology (BST), which makes it more sensitive to the infrared light it uses.
The Samsung ISOCELL Vizion 63D will be used in service and industrial robots, as well as in XR devices and facial recognition. XR (ie AR and VR) is also the main focus point for the second sensor as well.
ISOCELL Vizion 931 is the main shutter sensor. Typically, an image sensor reads line by line – but this means that a fast-moving object would move between lines. This also applies to the camera if it moves quickly. Either way you get a rolling shutter effect, which makes image recognition tasks more difficult because the software has to iron out the distorted image.
The Vizion 931 is a main shutter sensor, which means all pixels are captured at once, without distortion. This is a 640 x 640 pixel sensor that can be used for iris recognition, eye tracking, as well as face and gesture recognition in headset devices like XR glasses.
SamsungSuch devices will likely require more than one sensor, so Samsung has implemented something called “multi-drop” that allows connecting up to four Vizion 931 sensors with a single cable, simplifying the connection of the product.
