Image processing for exposure bracketing

Abstract

This disclosure provides systems, methods, and devices for image signal processing that support image signal processing of exposure bracketed image frames. In a first aspect, a method of image processing includes receiving, by at least one processor, image data comprising first image data of a first exposure duration, second image data of a second exposure duration, and third image data of a third exposure duration, wherein the first exposure duration is equal to the third exposure duration; determining, by the at least one processor, fourth image data by subtracting corresponding pixel intensity values of the third image data from the second image data; and determining, by the at least one processor, a first output image frame by combining the fourth image data with the first image data. Other aspects and features are also claimed and described.
