摘要： In one example, a method for white balancing image data includes obtaining, for a zone of a color space, a mesh defining a plurality of polygons having vertices that are each associated with one or more white balance parameters; identifying a polygon of the plurality of polygons that includes a pixel of the image data; determining one or more white balance parameters for the pixel of the image data based on an interpolation of white balance parameters associated with vertices of the polygon that includes the pixel of the image data; and performing, based on the one or more white balance parameters for the pixel of the image data, a white balance operation on the pixel of the image data.

摘要： A multi-point measurement of a scene captured in an image frame may be used to process the image frame, such as by applying white balance corrections to the image frame. In some examples, the image frame may be segmented into portions that are illuminated by different illumination sources. Different portions of the image frame may be white balanced differently based on the color temperature of the illumination source for the corresponding portion. Infrared measurements of multiple points in the scene may be used to determine a characteristic of the illumination source of different portions of the scene. For example, a picture that includes indoor and outdoor portions may be illuminated by at least two illumination sources that produce different infrared measurements values. White balancing may be applied differently to these two portions to correct for color temperature of the different sources.

摘要： A device for camera processing is configured to receive a preview image, and determine if the preview image is a high dynamic range (HDR) scene based on brightness values of pixels of the preview image. The device may further determine to use a single frame image capture technique based on a determination that the preview image is not an HDR scene, and determine to use one of a plurality of HDR image capture techniques based on a determination that the preview image is an HDR scene, and further based on motion detected in the preview image. The device may then generate an output image using one or more images captured using the single frame image capture technique or one of the plurality of HDR image capture techniques.

摘要： A processor generates a depth map from two images, including a high-dynamic range (HDR) image. The processor receives, from a first image sensor, one or more first images, wherein the one or more first images have a first field-of-view (FOV) and a first resolution, and receives, from a second image sensor, one or more second images, wherein the one or more second images have a second FOV and a second resolution. The processor generates a first HDR image from the one or more first images, and performs tone alignment on the one or more second images based on the first HDR image to produce a second HDR image. The processor generates a depth map using the first HDR image and the second HDR image. The processor may use the depth map to apply a bokeh effect to the first HDR image.

摘要： Techniques and systems are provided for improving one or more image capture operations. In some examples, a system determines, based on data from one or more sensors, a movement of an image capture device associated with a capture of a plurality of image frames. The systems adjust a position of at least one object in each of the plurality of image frames based on the movement of the image capture device. The system determines a motion of the at least one object based on a difference in the adjusted position among the plurality of image frames. The system selects a value for at least one image capture parameter associated with the plurality of image frames based on the motion of the at least one object.

摘要： Systems and methods for processing one or more images include an apparatus (e.g., an application platform) that can obtain non-linear image data associated with an image and one or more linear statistics of the image. The apparatus can determine one or more non-linear statistics of the image and one or more non-linear statistics of a portion of the image using the non-linear image data. The apparatus can determine a relation between the one or more non-linear statistics of the portion of the image and the one or more non-linear statistics of the image and estimate one or more linear statistics of the portion of the image based on the relation and the one or more linear statistics of the image. The apparatus can determine brightness for at least the portion of the image based at least on the estimated one or more linear statistics of the portion of the image.
