With domestic dToF sensors, laser autofocus returns to flagship smartphones 1

The dToF (direct Time of Flight) sensor is an advanced distance sensing technology that calculates distance by measuring the time it takes for a laser pulse to travel from emission, reflect, and return to the BQ2004SNTR sensor. This technology has garnered renewed widespread attention in the smartphone industry, as it significantly enhances autofocus performance and enables more precise depth information acquisition for mobile camera systems. The application of domestically produced dToF sensors marks China's progress in high-end smartphone manufacturing technology while delivering users an even more diode exceptional camera experience.diode

In early smartphones, autofocus technology primarily relied on phase detection autofocus (PDAF) and contrast detection autofocus (CDAF). PDAF determines focus by measuring phase differences, while CDAF identifies focus by detecting the maximum contrast. Although these technologies were quite advanced, they still had certain limitations in low-light conditions and capturing fast-moving objects.diode
