Abstract: An extended reality (XR) system receives capture information from a first camera with a first image sensor that faces a first direction, for instance facing an environment. The capture information is associated with capture of first image data by the first image sensor, for instance including the first image data and/or first image capture settings used to capture the first image data. The XR system determines an image capture setting, such as an exposure setting, for a second image sensor based on the capture information. The second image sensor faces second direction, for instance facing a user of the XR system. In some examples, the XR system determines the image capture setting also based on information from a display buffer for a display that faces the second direction. The XR system causes a second image sensor to capture second image data according to the image capture setting.

Abstract: Aspects of the present disclosure relate to systems and methods for performing automatic white balance (AWB). An example device may include a memory and a processor coupled to the memory. The processor may be configured to receive a first image of a scene, measure a first illuminant of the first received image, compare the first illuminant and a first illuminant value, determine the scene is changing between the first received image and a previous image based on the comparison, adjust a first AWB convergence rate to a second AWB convergence rate in response to determining the scene is changing, and converge from a first balancing factor to a second balancing factor for one or more white balance operations based on the second AWB convergence rate.

Abstract: Among other things, the present disclosure relates to image searching. With a depth map, image pixels of an image having depth values intersecting a desired optical field can be identified. A territory can be set based on locations of the identified image pixels. Feature detection can be performed on the image within the set territory. The feature detection can be limited to the set territory.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support image signal processor to support reduced latency mode switching. In a first aspect, a method of image processing includes switching between different binning configurations to change an output of data from an image sensor. The binning configurations may include a first binning configuration to support object tracking and/or other artificial intelligence (AI) or computer vision (CV) applications and a second binning configuration to support photography or other still image capture applications. Other aspects and features are also claimed and described.

Abstract: Methods, systems, computer-readable media, and apparatuses for region-of-interest (ROI) automatic gain or exposure control are presented. In one example, a method includes receiving a first image from an image sensor captured with a first field of view (FOV) and comprising a first plurality of pixels, receiving a second image from the image sensor captured with a second FOV and comprising a second plurality of pixels, determining an ROI in the second image, the ROI comprising a subset of the second plurality of pixels in the second image, determining an ROI weight for the ROI in the second image, determining statistics based on the first plurality of pixels in the first image, the subset of the second plurality of pixels in the second image, and the ROI weight for the ROI in the second image, and adjusting a gain or exposure setting for the image sensor based on the statistics.

Abstract: Methods, systems, and devices for image processing at a device are described. The present disclosure may relate to capturing a first frame of image samples and a second frame of image samples of an image sensor after capturing the first frame of image samples, determining that a white balance confidence level of the second frame does not satisfy a confidence threshold, retrieving the first frame of image samples based on determining that the white balance confidence level of the second frame does not satisfy the confidence threshold, combining at least a portion of the image samples of the first frame with the image samples of the second frame, and determining a white balance setting for the second frame based on combining at least the portion of the image samples of the first frame with the image samples of the second frame.

Abstract: Methods, systems, and devices for image processing are described. The method includes using exposure control processes to set an exposure length for a set of one or more image pixels of a sensor, determining a light level of an environment of the sensor and a confidence level associated with a set of one or more autofocus pixels of the sensor, selecting one of a first exposure control process or a second exposure control process for the set of one or more autofocus pixels of the sensor, where the selection is based on the light level and the confidence level, performing an autofocus operation for the sensor based on an output of the one or more autofocus pixels and the selected one of the first or the second exposure control process, and outputting image data from the one or more image pixels of the sensor based on the autofocus 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.

Abstract: An under-display camera is positioned underneath a display of a mobile device. The under-display camera captures an image using light passing through a portion of the display. The mobile device displays a display image on the display, the display image based on the image. The mobile device displays an indicator overlaid over the display image on an indicator area of the display that overlaps with the portion of the display. The indicator may identify the position of the camera. The mobile device can compensate for occlusion of the camera by continuing to display a previous display image if a more recently captured image includes an occlusion. The mobile device can give users alternate ways to select areas of the display image to avoid camera occlusion, for instance using hardware buttons and/or touchscreen interface elements.
