Abstract: A method for de-flickering frames captured by a camera including 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, 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.
