Claim Text:
1. A method comprising: acquiring, at an electronic device, a first preliminary image and a second preliminary image for a subject through an image sensor operatively coupled to the electronic device; determining a candidate emission time related to an acquisition of an output image for the subject, based on a difference between state information of at least part of the first preliminary image and state information of at least part of the second preliminary image; comparing the candidate emission time to a synchronization period where a plurality of lines of the image sensor simultaneously acquires the output image; and acquiring the output image for the subject based at least in part on the comparison, wherein the acquiring the output image comprises, when the candidate emission time is smaller than or equal to the synchronization period, controlling a light emitting module operatively coupled to the electronic device to produce light at the candidate emission time in the synchronization period.
