Claim 2:
3. The electronic device according to claim 1, wherein the optical information comprises n images of the reflected light acquired in n times; and the processor is configured to:
determine a first characteristic region of an ith image in the n images and a second characteristic region of an (i+1)th mage in the n images, wherein 1≤i<n, and a similarity between the first characteristic region and the second characteristic region is greater than a similarity threshold;
determine a sub-trajectory of the light-emitting component corresponding to the ith image based on a position of the first characteristic region in the ith image and a position of the second characteristic region in the (i+1)th image; and
determine the movement trajectory based on sub-trajectories corresponding to first n−1 images in the n images.
