INFRARED-BASED PROCESSING OF AN IMAGE
20220385873 · 2022-12-01 ·

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.
