description Disclosed are various embodiments of high dynamic range (HDR) video. In one embodiment a method includes obtaining first and second frames of a series of digital video frames, where the first and second frames have different exposure levels. The second frame is reregistered with respect to the first frame based at least in part upon motion estimation, where the motion estimation accounts for the different exposure levels of the first and second frames, and the first frame is combined with the reregistered second frame to generate an HDR frame. In another embodiment, a video device includes means for attenuating the exposure of a video frame captured by an image capture device and an HDR converter configured to combine a plurality of digital video frames to generate an HDR frame, where each digital video frame combined to generate the HDR frame has a different exposure level.
