USING AN IMAGE SENSOR FOR ALWAYS-ON APPLICATION WTHIN MOBILE DEVICE

A mobile device includes an application processor and an image sensor. The application processor includes an imaging subsystem configured to process high resolution image data through a first interface and a sensor hub configured to process sensor data through a second interface. The image sensor operates in one of first and second modes. The image sensor is configured to capture the high resolution image data in response to a request from the imaging subsystem and the imaging subsystem is configured to access the high resolution image data using the first interface for performing a first operation, during the first mode. The image sensor is configured to capture low resolution image data and the sensor hub is configured to access the low resolution image data using the second bus for performing a second operation, during the second mode. 一种移动设备，包括应用处理器和图像传感器。应用处理器包括：成像子系统，被配置为处理通过第一接口的高分辨率图像数据；以及传感器集线器，被配置为处理通过第二接口的传感器数据。所述图像传感器在第一模式和第二模式中的一种模式下操作。在第一模式期间，图像传感器被配置为响应于来自成像子系统的请求而捕获高分辨率图像数据，并且成像子系统被配置为使用第一接口来访
