Abstract: Methods, systems, and devices for minimizing ghosting in high dynamic range image processing are described. The method may include capturing from a sensor of the device a downscaled first frame of a first exposure length and a downscaled second frame of a second exposure length that is longer than the first exposure length, identifying a highlight region associated with the downscaled first frame and a motion region associated with the downscaled first frame and with the downscaled second frame, blending the motion region in accordance with determining whether at least a portion of the motion region overlaps the highlight region, and incorporating the blending of the motion region in a set of full resolution frames.
