Abstract
A method and a device for obtaining a high dynamic range image are provided. The method includes: obtaining a pixel value of each pixel in two images of a same scene; determining a brightness value of each pixel in the two images; determining an objective brightness value of each pixel in a combined image combining the two images; determining a color value of each pixel in the two images; determining a color value of each pixel in the combined image; correcting the color value of each pixel in the combined image so as to obtain a corrected color value of each pixel in the combined image; determining a pixel value of each pixel in the combined image; and obtaining a high dynamic range image.
