With domestic dToF sensors, laser autofocus returns to flagship smartphones 2

The advantage of dToF sensors lies in their high precision and fast response time. They are unaffected by ambient light, enabling stable performance across a wide range of lighting conditions—from bright outdoor environments to dimly lit indoor spaces. Additionally, dToF sensors are compact in size, making them easy to integrate into the sleek designs of modern smartphones.

The laser autofocus system employs a laser emitter that emits low-power infrared laser beams, which are then received by a dToF sensor after reflection. This method makes laser autofocus particularly effective for quickly and precisely focusing on distant objects. It also significantly improves continuous autofocus performance during video recording, resulting in a smoother shooting experience.diode

The development and application of domestically produced dToF sensors not only demonstrate China's advancements in high-end manufacturing and semiconductor technology but also reflect a deep understanding of domestic consumer needs. With the advent of the 5G era, consumers are placing increasingly higher demands on smartphone photography capabilities, making fast and accurate autofocus technology a key factor in enhancing user experience.diode

The dToF sensor features a MIPI CSI-2 interface supporting both histogram mode and DSP mode data formats. Utilizing the CSI-2 single-channel interface, the sensor enables image transmission at full resolution with a frame rate of 30 fps. Internally, the sensor incorporates an MCU to facilitate software patches and enhance system programmability, along with the integration of CoreVision Gen2 DSP deep signal processing module, which improves accuracy and environmental noise resistance.diode
