ToF: Samsung releases its 1st indirect ToF chip
Samsung unveils its first iTOF product — ISOCELL Vizion 33D:
“Featuring 4-tap pixels, the Samsung ISOCELL Vizion 33D delivers precise and swift depth sensing capabilities for next-level 3D applications.
Enabling pro-grade shots with bokeh effects or accurate 3D object images, the ToF (Time-of-Flight) sensor is optimized to provide best-in-class photography and AR/VR experiences.
To enable precise depth measurement of fast-moving objects, the ISOCELL Vizion 33D features a 4-tap demodulation system and supports frame rate of up to 120fps. Each pixel in the sensor can receive four phase signals simultaneously (0°, 90°, 180°, and 270°), which means it can generate a depth image with just a single frame. The ISOCELL Vizion 33D can capture moving objects with significant reduction of motion artifacts.
In both indoor and outdoor conditions, the sensor can detect the depth of an object within up to 5m with high accuracy. ISOCELL’s pixel technology, coupled with high resolution, enables the sensor to accurately separate objects from the background with 3D bokeh effect.
Deep Trench Isolation technology (DTI) maximizes isolation between pixels to reduce crosstalk, while Backside Scattering Technology (BST) enhances the sensor’s quantum efficiency. With high-precision depth images, the ISOCELL Vizion 33D delivers next-level 3D applications, such as facial authentication for payment services.
With a total power consumption of under 400mW for both IR illuminator and the ToF sensor, the 33D makes it possible for users to enjoy powerful 3D features, such as AR games and video bokeh, throughout the day.”
