Abstract: An electronic device is provided that includes one or more image sensors configured to capture a video feed, an image signal processor configured to perform color correction on the captured video feed based on a brightness level computed from the captured video feed and/or based on a color temperature or illuminant type of the lighting in the captured video feed to generate a corresponding color corrected video feed using a first chromatic adaptation model that is adapted to an immersive viewing condition, and one or more displays configured to output the color corrected video feed. The electronic device can further include a recording pipeline configured to record a version of the captured video feed and can share or transmit the recorded content to an external device. The external device can display the recorded content using a second chromatic adaptation model that is adapted to a non-immersive viewing condition.

Abstract: An apparatus can include a first image sensor having a first field of view (FOV) and configured to capture a first image, a second image sensor having a second FOV and configured to capture a second image, an image statistics collection subsystem configured to gather first image statistics information associated with the first image and to gather second image statistics information associated with the second image, a disparity detection subsystem configured to compare the first image statistics information with the second image statistics information, and image signal processing blocks configured to synchronize processing of the first and second images based on the comparison of the first image statistics information with the second image statistics information. Processing of the first and second images can involve using one or more combined image signal processing control parameters based on image statistics information within an overlapping FOV and/or a within a total FOV.

Abstract: A head-mounted device is provided that includes one or more image sensors configured to capture a video feed, one or more motion sensors configured to detect motion, and control circuitry configured to analyze a lighting condition of the captured video feed and to perform auto white balancing operations on the captured video feed. An update frequency or a color adaptation speed of the auto white balancing operations can be determined based on the lighting condition and the detected motion. The color adaptation speed of the auto white balancing operations can be adjusted only in response to detecting, using the one or more motion sensors, an amount of motion exceeding a threshold.

Abstract: Devices, methods, and non-transitory program storage devices are disclosed to: obtain an input image; identify a first face in the input image; divide the first face into a plurality of regions; identify obstructions in one or more of the plurality of regions; select a subset of regions, based on the identified obstructions; and determine a white point for the first face based, at least in part, on the selected subset of regions. In some embodiments, obstructions may be identified using a face obstruction detection model (e.g., a logistic regression model trained based on a large dataset of annotated facial images with and without obstructions). The identified obstructions may comprise, e.g., facial hair, head hair, glasses, a facial covering, a head covering, a face mask, or clothing. In some embodiments, a white balancing operation may be performed on the input image based, at least in part, on the determined white point.
