摘要：
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.
摘要（中）：
提供了一种用于获得高动态范围图像的方法和设备。 该方法包括：获取同一场景的两幅图像中每个像素的像素值; 确定两幅图像中每个像素的亮度值; 确定组合这两个图像的组合图像中的每个像素的目标亮度值; 确定两个图像中每个像素的颜色值; 确定组合图像中每个像素的颜色值; 校正组合图像中每个像素的颜色值，以获得组合图像中每个像素的校正颜色值; 确定组合图像中每个像素的像素值; 并获得高动态范围图像。
