Abstract: Methods and devices for camera initialization are disclosed. In some aspects, a device includes a first camera to capture one or more first image frames, a second camera to capture one or more second image frames, and a camera controller coupled to the first camera and the second camera. The camera controller is configured to initialize the first camera, to cause the second camera to capture one or more second image frames while initializing the first camera, to determine an initial capture setting for the first camera based on the one or more second image frames captured by the second camera, and to complete initialization of the first camera using the initial capture setting.

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 operating a device that includes an image sensor including a plurality of pixels includes: detecting visible light communication (VLC) signals with the image sensor; obtaining image data based on the VLC signals, the image data including a set of brightness components and possibly a set of chrominance components, and each brightness component of the set of brightness components being associated with a respective pixel of the plurality of pixels and (if available) each chrominance component of the set of chrominance components being associated with a respective pixel of the plurality of pixels; and decoding the set of brightness components to obtain information encoded in the VLC signals using a processor of the device without decoding, if available, the set of chrominance components.

Abstract: Systems, methods, and non-transitory media are provided for automatic exposure control. An example method can include receiving pixel values captured by a photosensor pixel array (PPA) of an image sensor, wherein one or more pixel values from the pixel values correspond to one or more sensitivity -biased photosensor (SBP) pixels in the PPA and one or more saturated pixel values from the pixel values correspond to one or more other photosensor pixels in the PPA; determining, based on the one or more pixel values, an actual pixel value for the one or more pixel values and/or the one or more saturated pixel values; determining an adjustment factor for at least one of the pixel values based on the actual pixel value and a target exposure value; and based on the adjustment factor, correcting an exposure setting associated with the image sensor and/or at least one of the pixel values.

Abstract: In one implementation, an electronic visual-rendering device includes an eye-tracking sensor and at least a first component. The eye-tracking sensor is configured to detect an eye-close event and, in response, output an eye-close-event message. The first component is configured to operate in at least a normal-power mode and a first low-power mode. The first components is configured to transition from operating in the normal-power mode to operating in the first low-power mode in response to the eye-tracking sensor's output of the eye-close-event message.

Abstract: Image frames for computational photography may be corrected, such as through rolling shutter correction (RSC), prior to fusion of the image frames to reduce wobble and jitter artifacts present in a video sequence of HDR-enhanced image frames. First and second motion data regarding motion of the image capture device may be determined for times corresponding to the capturing of the first and second image frames, respectively. The rolling shutter correction (RSC) may be applied to the first and second image frames based on both the first and second motion data. The corrected first and second image frames may then be aligned and fused to obtain a single output image frame with higher dynamic range than either of the first or second image frames.

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.
