Samsung Electronics Co., Ltd. has introduced two new ISOCELL Vizion sensors. The ISOCELL Vizion 63D is a time-of-flight (ToF) sensor and the ISOCELL Vizion 931 is a global shutter sensor. First introduced in 2020, Samsung’s ISOCELL Vizion lineup includes a ToF sensor and a global shutter sensor specifically designed to provide visual capabilities for a wide range of next-generation mobile, commercial, and industrial use cases. corresponds to
Just as bats use echolocation to navigate in the dark, ToF sensors measure distance and depth by calculating the time it takes for emitted light to travel to an object and back. In particular, Samsung’s ISOCELL Vizion 63D is an indirect ToF (iToF) sensor that measures the phase shift between emitted and reflected light to sense the surroundings in three dimensions. With exceptional precision and clarity, his Vizion 63D is ideal for service and industrial robots as well as XR devices and facial recognition where high resolution and accurate depth measurement is critical.
The ISOCELL Vizion 63D sensor is the industry’s first iToF sensor with integrated depth sensing hardware image signal processor (ISP). This innovative one-chip design allows for accurate capture of 3D depth information without the use of a separate chip, reducing system power consumption by up to 40% compared to previous generations. This sensor is also capable of processing images at up to 60 frames per second in his QVGA resolution (320×240), a high-demand display resolution used in commercial and industrial markets.
Based on the industry’s smallest 3.5mm. Depending on the pixel size of the iToF sensor, ISOCELL Vizion 63D achieves high Video Graphics Array (VGA) resolution (640×480) within 1/6.4? The optical format makes it ideal for compact on-the-go devices. Thanks to back scattering technology (BST) that enhances light absorption, the Vizion 63D sensor boasts the industry’s highest quantum efficiency, reaching 38% at an infrared light wavelength of 940 nanometers (nm). This allows for increased light sensitivity and reduced noise, resulting in sharper image quality with minimal motion blur.
Additionally, ISOCELL Vizion 63D supports both flood (high resolution at close range) and spot (long range) illumination modes, significantly extending the measurable distance range from 5 meters on the previous model to 10 meters. Ta. Global shutter image sensor tuned to capture fast movements without creating a “jelly effect”. Unlike a rolling shutter sensor, which scans the scene line by line from top to bottom in a ‘rolling’ manner.
In this way, a global shutter sensor captures the entire scene at once, or “globally.” It’s the same as what the human eye sees. This allows the ISOCELL Vizion 931 to capture clear, undistorted images of moving objects, making it ideal for motion tracking of XR devices, gaming systems, service and logistics robots, and drones.
ISOCELL Vizion 931 is designed with a 1:1 ratio of VGA resolution (640 x 640) that packs more pixels into a smaller form factor for iris recognition, eye tracking, and face and gesture detection in head-mounted displays. It’s perfect. Devices such as XR headsets. ISOCELL Vizion 931 also achieves the highest quantum efficiency in the industry, an impressive 60% at the 850nm infrared wavelength. This feat was made possible by incorporating front deep trench isolation (FDTI), which places an insulating layer between pixels to maximize light absorption, in addition to the BST method used in the ISOCELL Vizion 63D.
The Vizion 931 supports multidrop, which allows up to four cameras to be seamlessly connected to an application processor using a single wire. With minimal wiring required, this sensor provides device manufacturers with great design flexibility. The Samsung ISOCELL Vizion 63D sensor and ISOCELL Vizion 931 sensor are currently being sampled to his OEMs around the world.
