The ToF (Time of Flight) sensors are capable of making a depth map of scenes thanks to their technology that measures the time it takes for an infrared beam to reach the sensor after bouncing off objects in its path. The time differences are translated into depth maps that help, for example, to calculate the masks used in portrait modes.
Samsung’s new ISOCELL Vizion 33D sensor is an improvement in this field, with the ability to track objects between 20 cm and 5 meters with 10 or 12-bit resolution and up to 120 fps. It requires 200 mW of power in specific uses and 400 mW for continuous tracking in applications of, for example, augmented reality.
Deep Tech Isolation technology is part of the ISOCELL sensor and reduces interference in pixel metering, enhancing the ability to separate the subject from the background. This sensor can be used for face ID. At the moment, Sony is the one that sells the most ToF sensors with a 50% market share. iPhone and iPads carry Sony sensors without going any further.
