Summary:In augmented reality (AR) headset devices, virtual image visibility and power consumption are major challenges. In this paper, we presented smart pixelated dimmer that locally enhance the ambient contrast ratio. The dimmer is integrated with image sensor and low‐power edge AI processor to control the dimming automatically. Adopting smart pixelated dimmer provides AR devices the possibility to operate in high brightness environment.
