1. A video processing method, comprising: dividing a currently processed frame into a top field and a bottom field, and performing field exposure on the top 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 that of the bottom field are different; processing the exposed top field and the exposed bottom field by using a de-interlacing technique 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.
