In one example, whether the N grayscale images are identical may be detected based on the position information corresponding to the N grayscale images or the feature information of the N grayscale images, and if the position information corresponding to the N grayscale images are identical, it indicates that the electronic device performs the multiple acousto-electric conversions at the same position, and the obtained N grayscale images are identical. If the feature information of the N gray-scale images is the same, the N gray-scale images are the same. By the method, whether N gray images are identical or not can be accurately detected, so that the accuracy of the obtained target image is improved.
