Abstract: An image capture method for flash photography includes: capturing at least one first image while a strobe device is operating under a first strobe intensity setting for emitting main flash, capturing at least one second image while the strobe device is operating under a second strobe intensity setting different from the first strobe intensity setting, and generating an output image by blending the at least one first image and the at least one second image.

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.
