KM02G

Product Description

The KM02G series processors are specially designed for AI glasses. The processors feature an advanced ISP (Image Signal Processor) and IPU (Image Processing Unit), enabling premium photo and video capture directly on the glasses. The key anti-shake technology actively suppresses camera shake and vibrations, delivering stable footage and clearer images even in dynamic scenarios. The KM02G series processors also integrate a NPU (Neural-network Processing Unit), which unlocks a wide spectrum of intelligent on-device AI applications, including gesture recognition for intuitive control and voice recognition for hands-free interactions. Moreover, the KM02G series processors’ compact package size and low power consumption make it ideal for lightweight, battery-efficient AI glasses.
