ToF sensor

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.

ToF depth sensing

new dimensions
with ToF sensor

Experience cutting-edge 3D depth sensing capabilities with ISOCELL Vizion 33D. Thanks to its 3D ToF sensor, the 33D can measure distances between the camera and the subject. Based on the time it takes for an infrared light signal to travel to and from an object, the sensor allows devices to detect depth information in real-time. From 3D scanning to video bokeh effects, and even seamless AR/VR experiences, the ISOCELL Vizion 33D’s ability to track moving objects with low latency holds the key to bringing depth sensing features to life.

4-tap demodulation

Create striking 3D images in real time

Moving too fast? No problem. 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.

High accuracy

Experience best-in-class
depth sensing applications

A new era of depth sensing features is here. As a high-resolution VGA ToF solution, the ISOCELL Vizion 33D produces depth images with unrivalled precision. 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.

Power efficiency

3D features with
superior power efficiency

Power through your day with 3D features without ever worrying about battery and overheating. Equipped with ISOCELL’s cutting-edge pixel structure, the ISOCELL Vizion 33D provides enhanced power efficiency, enabling the delivery of 3D applications around-the-clock. 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.

AF assistant

for razor-sharp images

Autofocus is an indispensable photography tool, especially when it comes to capturing crisp images in motion-packed situations. With its depth sensing capabilities, the ISOCELL Vizion 33D can assist the main camera for accurate and quick autofocus, replacing the laser sensor. Requiring just 200mW, a low level of power consumption, this feature adds liveliness to your photographs.
