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.

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.

Abstract: Devices, methods, and non-transitory program storage devices (NPSDs) are disclosed to compensate for the predicted color changes experienced by camera modules after certain amounts of time of real world use. Such color changes may be caused by prolonged exposure of optical components of the camera module to one or more of: solar radiation, high temperature conditions, or high humidity conditions, each of which may, over time, induce deviation in the color response of optical components of the camera module. The techniques disclosed herein may first characterize such predicted optical change to components over time based on particular environmental conditions, and then implement one or more time-varying color models to compensate for predicted changes to the camera module's color calibration values due to the characterized optical change. In some embodiments, optical changes in other types of components, e.g., display devices, caused by prolonged environmental stresses may also be modeled and compensated.

Abstract: Techniques for auto white balancing of captured images based on detection of flicker in ambient light is described. When flicker is detected in ambient light during an image capture event, and the flicker is unchanging during the image capture event, a white point of image data may be estimated according to a first technique. When flicker is detected in ambient light during an image capture event, and the flicker is changing during the image capture event, a white point of image data may be estimated according to a second technique. When flicker is not detected, a white point of image data may be estimated according to a third technique. Image data may be color corrected based on the estimated white point.

Abstract: A document may include a non-magnetic substrate, a first colorant mixture printed as a first image upon the substrate, the first colorant mixture including a magnetic ink, and a second colorant mixture printed as a second image upon the substrate in substantially close spatial proximity to the printed first colorant mixture. The second colorant mixture may consist essentially of one or more non-magnetic inks and exhibit properties of both low visual contrast and high magnetic contrast against the first colorant mixture, such that the resultant printed substrate does not reveal the first image to the human eye, but will reveal the first image to a magnetic image reader.

Abstract: Displaying wide-gamut images as intended on color-managed wide-gamut display systems while rendering a visually consistent image when rendered on targeted narrow-gamut display systems (regardless of whether the narrow-gamut displays are color-managed). Images represented in accordance with this disclosure are referred to as a dual-target images (DTI): one target being the image's original wide-gamut color space, the other target being a specified narrow-gamut color space. The novel representational scheme retains narrow-gamut rendering for those colors in a wide-gamut image that are within the targeted narrow-gamut color space, transitioning to wide-gamut rendering for those colors in the wide-gamut image that are outside the targeted narrow-gamut color space. This approach minimizes pixel clipping when rendering a wide-gamut image for a narrow-gamut display, while allowing the original wide-gamut pixel values to be recovered when rendering for a wide-gamut display.

Abstract: In general, techniques are disclosed for displaying wide-gamut images as intended on color-managed wide-gamut display systems while rendering a visually consistent image when rendered on targeted narrow-gamut display systems (regardless of whether the narrow-gamut displays are color-managed). For this reason, an image represented in accordance with this disclosure is referred to as a dual-target image (DTI): one target being the image's original wide-gamut color space, the other target being a specified narrow-gamut color space. The novel representational scheme described herein retains narrow-gamut rendering for those colors in a wide-gamut image that are within the targeted narrow-gamut color space, transitioning to wide-gamut rendering for those colors in the wide-gamut image that are outside the targeted narrow-gamut color space.

Abstract: Method and device for data search are provided. The method includes: retrieving a first serialized data corresponding to a first user identifier in a non-relational database; deserializing the first serialized data to obtain a first index; performing a search based on the first index. In the embodiments of the present disclosure, serialized data corresponding to a user identifier may be retrieved and deserialized into an index by a server in a NoSQL database and a search may be performed based on the index. Since the search is performed against data corresponding to user identifiers rather than all users, a much smaller search scope is covered, leading to an improved search speed and performance and optimized user experience.

Abstract: Methods and systems for detecting an object borderline. A first image with respect to the object can be captured by an image-capturing unit without a flash light and borderlines of the object can be detected. If the detection is successful, the detected borderlines can be outputted. Otherwise, a second image with respect to the object can be captured by the image-capturing unit by applying a flash light and the borderlines can be detected in the image. A geometric transformation between the two images can then be estimated. Finally, the border lines in the first image can be determined by transforming the borderlines detected in the second image. Such an approach effectively detects the appliance borderlines and avoids artifacts caused by applying flash.
