Patent ID: 8749699

Claim:
A video processing method, comprising: dividing a currently processed frame into a top field and a bottom field; performing field exposure on the to field and the bottom field respectively to acquire an exposed top field and an exposed bottom field, wherein a field exposure time length of the top field and a field exposure time length of the bottom field are different; calculating motion information of the top field or the bottom field using a neighboring frame as a reference field; processing the exposed top field and the exposed bottom field by using a de-interlacing technique and the calculated motion information to acquire two reconstructed exposed frames; and performing image enhancement processing on the two reconstructed exposed frames to acquire an image of the currently processed frame, wherein calculating the motion information of the top field or the bottom field using the neighboring frame as the reference field comprises: using a long exposed top field and a shortly exposed bottom field of the currently processed frame and a top field of the neighboring frame as first reference fields to calculate motion information of the bottom field of the currently processed frame; and using the long exposed top field and the shortly exposed bottom field of the currently processed frame and a bottom field of the neighboring frame as second reference fields to calculate motion information of the top field of the currently processed frame, and wherein processing the exposed top field and the exposed bottom field by using the de-interlacing technique and the calculated motion information to acquire the two reconstructed exposed frames comprises: using the motion information of the bottom field of the currently processed frame and the first reference fields to reconstruct the long exposed bottom field of the currently processed frame, which is combined with the long exposed top field of the currently processed frame to form a reconstructed long exposed frame of current time; and using the motion information of the top field of the currently processed frame and the second reference fields to reconstruct the shortly exposed top field of the currently processed frame, which is combined with the shortly exposed bottom field of the currently processed frame to form a reconstructed shortly exposed frame of the current time.
