Abstract: A method of camera processing including receiving a first image, determining one or more first automatic white balance (AWB) parameters for the first image, determining one or more second AWB parameters for a region-of-interest (ROI) of the first image, applying the one or more first AWB parameters to one or more of the first image or a second image, and adjusting the ROI of one or more of the first image or the second image based on the one or more second AWB parameters.

Abstract: This disclosure provides systems, methods, and devices for image processing that support enhanced white balancing operations. In a first aspect, a method of image processing includes receiving first image data from an image sensor; determining to adjust a white balancing operation from a first white balance point to a second white balance point; determining a first intermediate white balance point based on the first white balance point, the second white balance point, and a white balance reference line; receiving second image data from the image sensor; and applying white balancing to the second image data based on the first intermediate white balance point. Other aspects and features are also claimed and described.

Abstract: 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.

IPC: H04N23/88
Abstract: This disclosure provides systems, methods, and devices for image processing that support enhanced white balancing operations. In a first aspect, a method of image processing includes receiving first image data obtained at a first aperture; determining a first output image frame based on the first image data by applying a first white balancing to at least a portion of the first image data; receiving second image data obtained at a second aperture; and determining a second output image frame based on the second image data by applying a second white balancing based on the first aperture and the second aperture to at least a portion of the second image data. The second white balancing may be based on a first compensation factor based on the first aperture and the second aperture used to adjust the first white balancing. Other aspects and features are also claimed and described.
