Abstract
A method for reducing overexposure or underexposure in a time-lapse includes acquiring, using an image capture device, a first frame of the time-lapse using a first exposure setting; and acquiring, using the image capture device, a second frame of the time-lapse. The first frame of the time-lapse is acquired under a first luminance condition. The second frame of the time-lapse is acquired under a second luminance condition that is different from the first luminance condition. The second frame of the time-lapse is acquired using an exposure setting that is determined based on respective exposure settings of one or more preview images obtained between the first frame of the time-lapse and the second frame of the time-lapse. The one or more preview images are not included in the time-lapse.
