Supported by domestic dToF sensors, laser focusing returns to flagship phones 1

DToF (Direct Time of Flight) sensor is an advanced distance sensing technology that calculates distance by measuring the time required for laser pulses to be emitted, reflected, and returned to the BQ2004SNTR sensor. This technology has regained widespread attention in the smartphone industry as it brings significant improvements in autofocus performance and more accurate depth information acquisition capabilities to mobile camera systems. The application of domestically produced dToF sensors marks China's progress in high-end smartphone manufacturing technology, while providing users with a more outstanding camera experience.diode

In early smartphones, autofocus technology mainly relied on phase detection autofocus (PDAF) and contrast detection autofocus (CDAF). PDAF determines focus based on phase difference, while CDAF determines focus based on maximum contrast value. Although these technologies are quite mature, they still have some limitations in low light environments and capturing high-speed moving objects.diode

The advantage of dToF sensors lies in their high precision and fast response time. It is not affected by ambient light, so it can work stably under various lighting conditions, providing reliable performance from bright outdoors to dim indoors. In addition, dToF sensors are compact in size and easy to integrate into the compact design of modern smartphones.diode
