專利摘要

A method for high dynamic range imaging includes the steps of arranging at least two cameras parallel and meanwhile capturing a plurality of images of one scene with different exposures by the at least two cameras; adjusting the captured images for the same exposure thereof subject to the response functions of the cameras respectively and then defining a plurality of characteristic spots in each of the images; combining the characteristic spots corresponding to the images respectively to get a displacement of the corresponding characteristic spot in each image and to further get a disparity map; and applying the displacement between the two corresponding characteristic spots in the corresponding images and synthesizing the images to form a synthetic image.
