South Korean company Samsung has unveiled a new 3D sensor for a Time-of-Flight (ToF) camera called the Samsung ISOCELL Vizion 33D.

Samsung’s ISOCELL Vizion 33D sensor captures accurate distance data and tracks fast-moving subjects for fast autofocus and background blur in movies.

The Samsung ISOCELL Vizion 33D sensor creates depth maps with a resolution of 640 x 480 pixels. The pixel size is 7 microns; the optical format of the sensor is 1 / 3.2 inches. It can measure distances from 0.2 m to 5 m with a 10 to 12-bit resolution. The maximum frame rate for motion tracking is 120 frames per second.

When used as an AF assist, 200mW of power is required for both the sensor and the IR illuminator. For continuous tracking such as augmented reality gaming and bokeh video rendering, the power consumption reaches 400 mW. However, the manufacturer claims that it will still not hit the smartphone battery hard.

ISOCELL’s Deep Trench Isolation technology reduces crosstalk between pixels, which helps the sensor to separate the subject from the background clearly. Samsung’s ISOCELL Vizion 33D sensor can also be used for facial recognition, to protect mobile payment applications and unlock the phone so that it will be used in both front and main cameras of smartphones.
