Samsung Launches 4-Tap iTOF Sensor

 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."


  1. Has anyone any idea, where this image sensor can be purchased or tested, it really sounds together with teh publication by Samsung very interesting.
    Best regards

  2. We started this work at Samsung in 2008 under VP YD Park as a research project. It was shelved in about 2012 or 2013 after our ISSCC paper on a RGBZ (iTOF) sensor and YD left Samsung and put in the freezer. I am glad to see it revived and that the work includes a few of the original team members! When you are a fast-follower and product gorilla, you don't have to be first to market.

    1. Good news!
      Thanks for professor Fossum's contributions.

  3. Thank you! Would you say that this is better than what is being used in the iPhone 12 Pro?
