Abstract: Some dynamic pixel binning methods may involve identifying ROI optical sensor data corresponding to optical sensor pixels in a region of interest (ROI). Some such methods also may involve identifying non-ROI optical sensor data corresponding to optical sensor pixels outside the region of interest and determining a first binning factor for the non-ROI optical sensor data. The first binning factor may be based on a number of pixels in the region of interest and a target output data rate. Some such methods also may involve applying the first binning factor to the non-ROI optical sensor data and outputting optical sensor data, including the binned non-ROI optical sensor data, at the target output data rate.

Abstract: Systems and methods for performing HDR imaging are described. Aspects of the disclosure may include a camera system that uses the same pixels to capture both short and long exposure pixel data to improve camera hardware efficiency and pixel efficiency, and to reduce power usage by the camera system. In some aspects, exposure of a plurality of pixels available in a device may be started. Pixel data from the plurality of pixels may be captured after a first time period has elapsed to obtain short exposure pixel data. Pixel data from the plurality of pixels may also be captured after a second time period, longer than the first time period, has elapsed to obtain long exposure pixel data. The short exposure pixel data and the long exposure pixel data may be processed to create HDR images and/or videos.

Abstract: A mobile device is disclosed. The mobile device may receive one or more wireless local area network (WLAN) signals. The mobile device may determine Channel State Information (CSI) data from the one or more WLAN signals. The mobile device may determine one or more environmental characteristics associated with an environment of the mobile device based on the CSI data. The mobile device may send information indicative of the one or more environmental characteristics to a location server (LS), or determine a position of the mobile device based at least in part on the one or more environmental characteristics, or any combination thereof.

Abstract: Methods, systems, and devices for in-display camera activation are described. The method includes receiving a request to activate a camera of the device, identifying a start of frame marker associated with activating the camera in response to the request, and emitting a signal to a display of the device in response to the identified start of frame marker, where the emitted signal triggers the display to transition a set of liquid crystal elements of the display from a display mode to a camera mode for camera operation.

Abstract: Methods, systems, and devices for dual phase detection auto focus (PDAF) power optimization are described. A camera device may capture a frame including a pixel array representing a scene. In some examples, each pixel of the pixel array may be a phase detection (PD) pixel having one or more values, or one or more PD pixels positioned randomly across the pixel array. The camera device may identify a configuration of the pixel array, and determine a condition of the pixel array relative to the configuration. The configuration may be a binning configuration or a frame pattern configuration, and the condition may include an illumination condition related to the pixel array representing the scene. The camera device may determine and apply a reconfiguration to at least a portion of the pixel array based on the condition of the pixel array, and determine a lens position of the camera device therewith.
