本文提出一种适用于移动和可穿戴设备的始终开启CMOS图像传感器，功耗仅45.5μW，帧率15fps。通过用单个CIS替代接近、环境光、指纹等多种传感器，降低了系统功耗、面积和成本，并支持手势识别、人脸识别等智能传感功能。
Most mobile devices embed a CMOS image sensor (CIS) for capturing images. In addition, a variety of sensors such as proximity, ambient light, and fingerprint sensors are integrated for device control. The integration of multiple sensors in a device requires significant power consumption, area, and cost. In contrast to multiple sensors, an always-on CIS enables advanced smart sensing, including gesture sensing, face recognition, eye tracking, and so on. Smart sensing using a CIS offers a variety of user interfaces and experiences such as touch-less control, authentication, gaming, and object recognition for the Internet of Things (IOT). A major drawback of a CIS in mobile devices is that it consumes power greater than 50mW [1], and this is not feasible for always-on sensing that is required to function with the limited energy available from the device’s battery. Moreover, power reduction in a CIS causes image degradation owing to reduced
