Abstract: 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.

Abstract: An image sensor may include control circuitry, a plurality of pixels, and an image processor. Each pixel includes a photodetector, at least first and second storage nodes, and transfer circuitry. The transfer circuitry is responsive to control signals generated by the control circuitry to transfer first charges generated by the photodetector during a first exposure time within a frame period to the first storage node. Second charges may be generated by the photodetector during a second, longer exposure time during the frame period, and transferred to the second storage node. The image processor may generate image frame data based on output voltage samples derived from the first and second charges of each of the plurality of pixels.
