A method and apparatus for generating a high dynamic range image are disclosed by the present invention, which is used to remove "ghost" in the high dynamic range image. The method includes: for an image collecting area, obtaining N-frame low dynamic range images which have different exposure, wherein, N is an integer greater than or equal to 2; determining one frame low dynamic range image of the N-frame low dynamic range images as a reference image; in remaining N-1 frame low dynamic range images , determining a motion area of each frame image of K-frame low dynamic range images, wherein, K is an integer greater than 0 and less than or equal to N-1; based on the reference image, correcting the motion area of each frame image of the K-frame low dynamic range images, and generating K-frame corrected images; fusing the reference image and the K-frame corrected images, then generating one frame high dynamic range image.
