1. A method for de-flickering frames captured by a camera, comprising:
capturing a first frame with short exposure to generate a first short exposure frame;
capturing the first frame with long exposure to generate a first long exposure frame;
generating brightness energy information of the first frame according to the first short exposure frame and the first long exposure frame;
generating a first set of parameters according to the brightness energy information of the first frame;
generating brightness energy information of N next frames after the first frame according to the first set of parameters and the brightness energy information of the first frame, wherein N is a positive integer; and
generating de-flicker scalars of the N next frames after the first frame according to the brightness energy information of the N next frames after the first frame.
