Method and apparatus for generating high-dynamic-range image, and electronic device

Abstract

A method and apparatus for generating a high-dynamic-range image, storage medium, and electronic device are provided. The method comprises: obtaining a long-exposure visible-light image, a long-exposure near-infrared image, a short-exposure visible-light image, and a short-exposure near-infrared image of a target scene, wherein the short-exposure near-infrared image and the long-exposure near-infrared image are not overexposed, and bright regions of the short-exposure visible-light image are not overexposed; performing brightness reconstruction on an overexposed region of the long-exposure visible-light image based on the long-exposure near-infrared image, the short-exposure visible-light image, and the short-exposure near-infrared image; performing chromaticity reconstruction on the overexposed region of the long-exposure visible-light image based on the short-exposure visible-light image; and generating the high-dynamic-range image based on the long-exposure visible-light image, and results of the brightness reconstruction and the chromaticity reconstruction for the long-exposure visible-light image. In the obtained high-dynamic-range image, both bright and dark regions can be clearly imaged without ghosting.
