High Dynamic Range(HDR) imaging technology can help us enlarge the ratio between the lightest and darkest pixel to contain more details of real life to enhance our visual effect. Many researchers proposed methods to generate HDR image with multiple exposures images. However, some points with color distortion appeared if there existed some very bright things like light sources, or brilliant reflective objects. In this paper, using channel correlation, two color distortion elimination methods in HDR imaging are proposed. After several experiments, comparing with some conventional works, our proposals show better visual effect without no significant color distortion points.
