at an electronic device with one or more processors and memory:
receiving a plurality of frames of an image;
selecting one frame of the plurality of frames as a main frame thereby leaving the rest of the plurality of frames as reference frames;
aligning the reference frames with the main frame;
determining fusion weights for a respective reference frame of the reference frames by comparing the main frame and the respective reference frame; and
obtaining a weighted combination of the main frame and the reference frames based on the fusion weights.
