Abstract: A camera image sensor captures imaging pixel data and focus pixel data. The camera determines an imaging analog gain based on the imaging pixel data, and determines a focus analog gain based on the focus pixel data. When capturing the one or more subsequent frames, the image sensor applies the imaging analog gain to the imaging pixels and applies the focus analog gain to the focus pixels. Optionally, applying the focus analog gain to the focus pixels brings an average focus pixel luminance within a range, or brings a phase disparity confidence above a threshold.

CPC classification number: H04N5/347 , H04N5/232411
Abstract: In an aspect, camera sensor component receives, during a multi-virtual channel (VC) configuration session, a first configuration of a first VC associated with a first binning mode (e.g., full, 4×4, 8×8, etc.) and a second configuration of a second VC, the second configuration associated with a second binning mode (e.g., full, 4×4, 8×8, etc.). The camera sensor component detects trigger(s) to initiate streaming of activity frames associated with the first VC and the second VC. In response to the trigger(s), the camera sensor component streams first activity frames associated with the first VC in accordance with the first binning mode, and streams second activity frames associated with the second VC in accordance with the second binning mode.

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, computer-readable media, and apparatuses for region-of-interest automatic gain or exposure control are presented. One example method includes receiving an image from an image sensor, the image comprising a plurality of pixels, determining a region of interest (“ROI”) in the image, the ROI comprising a subset of the plurality of pixels in the image, determining a ROI weight for pixels in the subset of the plurality of pixels, determining statistics for the image based on the plurality of pixels in the image and the ROI weight, and adjusting a gain or exposure setting for the image sensor based on the statistics.

Abstract: A method of communication includes determining, at a mobile device, a speech quality metric for an incoming speech signal associated with a voice call. The speech quality metric is based on an environment of the mobile device. The method also includes converting incoming speech associated with the incoming speech signal to text in response to a determination that the speech quality metric fails to satisfy a speech quality metric threshold. The method further includes displaying the text at a display screen of the mobile device during the voice call.
