When the sound-electricity conversion is finished every time a gray image can be obtained, the completion of one scanning is indicated, and after the completion of the sound-electricity conversion, prompt information can be output to prompt the completion of one scanning so as to facilitate the user to check and know the scanning condition. For example, the prompt message may be a voice prompt message or/and a text prompt message, etc.
In one embodiment, synthesizing the N grayscale images to obtain the target grayscale image includes:
under the condition that the N gray level images are different, splicing the N gray level images based on the position information corresponding to the N gray level images to obtain a target gray level image;
and under the condition that the N gray level images are the same, carrying out image fusion processing on the N gray level images to obtain a target gray level image.
Under the condition that the N gray-scale images are different, the electronic equipment moves in the scanning process, different areas of an object to be scanned are scanned, and therefore the N gray-scale images can be spliced to obtain the target gray-scale image based on the position information corresponding to the N gray-scale images. Here, the position information may be understood as a position where the electronic device is located when the grayscale image is obtained. The N gray images are spliced to obtain the target gray image through the position information corresponding to the N gray images, and the splicing accuracy can be ensured, so that the accuracy of the target gray image is improved. In one example, the location of the electronic device may be recorded by a sensor, such as a gravity sensor or the like.
When the N grayscale images are identical, the N grayscale images are subjected to image fusion processing to obtain the target grayscale image, which indicates that the grayscale images obtained by performing the sound-electricity conversion at the same position by the electronic device are identical or the feature information is identical.
In one example, whether the N grayscale images are the same or not 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 is the same, it indicates that the electronic device performs multiple sound-electricity conversions at the same position, and the obtained N grayscale images are the same. If the feature information of the N grayscale images is the same, it indicates that the N grayscale images are the same. By the method, whether the N gray level images are the same or not can be accurately detected, so that the accuracy of the obtained target image is improved.
The above scanning method is described in detail with reference to an embodiment.

The reflected second ultrasonic wave reaches the ultrasonic fingerprint module 101, specifically can reach the ultrasonic receiving unit 1012 of ultrasonic fingerprint module 101. And different objects to be scanned have different reflected second ultrasonic time and intensity, and the gray level image can be generated by performing acousto-electric conversion. Second prompt information can be output subsequently to prompt the user that the scanning is completed.

The electronic device can be close to the object 103 to be scanned, so that the object 103 to be scanned can be tightly attached to the glass cover plate 104 of the electronic device and away from the outer side surface of the OLED display screen 102. By the scanning input of the user, the scanning is started, and a first ultrasonic wave is emitted to the side (outside the electronic device) of the glass cover plate 104 far away from the OLED display screen 102, and is reflected after passing through the object 103 to be scanned.
If the volume of the object to be scanned is large, the object to be scanned can be subjected to N times of first ultrasonic wave emission, N times of acousto-electric conversion are carried out, N gray level images are obtained, and the N gray level images are synthesized to obtain a target gray level image. Specifically, first, an ultrasound scanning mode is entered. Scanning is initiated by pressing a side key or otherwise.
Once scanned (i.e., once acousto-electric converted), a gray scale image is generated, and position information of the gray scale image is recorded through a sensor. And generating a scanning prompt tone, namely prompt information, so as to prompt the user to complete one scanning. Scanning for the Nth time to generate an Nth gray scale image, and recording position information, so that the N gray scale images can be obtained. Pressing a side key or other triggering means ends the scanning. And analyzing whether the N gray level images are the same according to the position information or the image characteristics, and if the N gray level images are the same, directly fusing the N gray level images to generate a target gray level image with high definition. The obtained high-definition target gray level image can be transmitted to the rear end for flatness analysis, micro-crack analysis, plant vein rubbing, inscription rubbing and the like.
If the images are analyzed to be different, splicing can be carried out according to the position information and the overlapping part information of the adjacent images to generate a complete target gray image. And carrying out flatness analysis, micro-crack analysis, plant vein rubbing, inscription rubbing and the like on the rear end of the complete target gray level image.
