For traditional high dynamic range(HDR) image synthesis method could not adapt to the dynamic illumination,the paper proposed a camera array-based different exposure images alignment and HDR image synthesis method.Firstly it captured different exposure images with the camera array whose calibration parameters had been calculated out,according to light field synthetic aperture photography theory,aligned different exposure images,and then did a second alignment to aligned images with the median threshold bitmap(MTB).According to different cameras' response curves fitted,it generated a HDR ima-ge with different exposure images second aligned.The experiments show that the proposed method can effectively synthesize HDR images in the dynamic illumination conditions,and achieves good results.
