Step 303: and carrying out N-time photoelectric conversion on the received second light based on the optical fingerprint module to obtain N gray level images.

N is a positive integer, and the second light is the reflected light of first light reflection to optical fingerprint module behind the object of waiting to scan.

Step 304: and synthesizing the N gray level images to obtain a target gray level image.

The

steps

301 and 302 correspond to the

steps

201 and 202 one by one, and are not described again.

In this embodiment, after receiving the scan input of the user, N times of scanning may be performed, and in each scanning process, the second light is received once to perform one time of photoelectric conversion, so that N grayscale images may be obtained. And then synthesizing the N gray level images to obtain a target gray level image. Therefore, even if the object to be scanned is large in size, N gray level images can be obtained through N times of scanning and are synthesized to obtain the target gray level image, the integrity of the target gray level image is ensured, and the scanned target gray level image can accurately represent the object to be scanned.

In one embodiment, controlling the OLED display to emit the first light outwards includes: controlling the OLED display screen to emit first light for N times;

carry out N photoelectric conversion to the second light of receiving based on optics fingerprint module, obtain N grey level images, include: and carrying out photoelectric conversion on the second light received each time based on the optical fingerprint module to obtain N gray level images.

During the N times of scanning, the OLED display screen can be controlled to emit N times of first light rays outwards, and the first light rays are controlled to emit one time each time the OLED display screen is scanned, so that the first light rays can be reflected one time, namely the optical fingerprint module can receive the N times of second light rays. Therefore, the light-emitting time of the OLED display screen can be reduced, and the electric energy is saved. The second light is received at every turn to the optics fingerprint module, can carry out photoelectric conversion to it, so, can realize carrying out photoelectric conversion to the N second light of reflection to obtain N grey level image.

In one example, the OLED display screen may be controlled to emit the first light for N times according to a preset interval duration or a preset distance. That is, the interval duration of the emission time between every two adjacent first light beams is the preset interval duration, that is, the electronic device emits the first light beams once every interval of the preset interval duration, so as to realize one-time scanning. Or the distance between the positions of the electronic equipment corresponding to every two adjacent first light rays is a preset distance, namely the electronic equipment sends the first light rays once when moving the preset distance, so that one-time scanning is realized, and the requirement on multiple times of scanning is met.

In one embodiment, the photoelectric conversion of the received second light based on the optical fingerprint module to obtain a gray scale image further includes: after completing one photoelectric conversion, the prompt information is output.

When a gray image can be obtained by completing the photoelectric conversion once, a scan is completed, and after the photoelectric conversion is completed, prompt information can be output to prompt that the scan is completed, so that a user can 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, indicating that the N grayscale images are the same grayscale images or the same feature information obtained by photoelectric conversion of the electronic device at the same position, the N grayscale images are subjected to image fusion processing to obtain the target grayscale image.

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 has performed multiple photoelectric 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.

As shown in fig. 1, taking the object 104 to be scanned as an object with an uneven surface (for example, with ridges and valleys), images with different gray levels are formed by sensing the difference of the reflected light source energy of the protruding portions (ridges) and the recessed portions (valleys) of the object 104 to be scanned, and the functions of flatness inspection, micro crack detection, vein rubbing and inscription paperless rubbing are realized. Firstly, entering a photoelectric fingerprint ridge-valley mode, approaching the electronic equipment to an object to be scanned, and tightly attaching the object 104 to be scanned to one side of the OLED display screen 103 of the electronic equipment, which is far away from the optical fingerprint module 101. By pressing a side key or in other modes, scanning is started, the OLED light emitting diode 102 in the OLED display screen 103 is controlled to be lightened, and a first light ray is emitted outwards, namely the OLED display screen 103 emits the first light ray outwards. The first light ray reaches the surface of the object to be scanned, and the first light ray is reflected. The reflected second light reaches the optical fingerprint module 101. The energy of the second light reflected by different ridges and valleys is different, and the second light is subjected to photoelectric conversion to generate a gray image. Second prompt information can be output subsequently to prompt the user that the scanning is completed. The obtained gray level image can be transmitted to the back end of the electronic equipment for analysis processing, such as flatness analysis, micro-crack analysis, plant vein rubbing, inscription rubbing, and the like. In one example, the electronic device further includes a glass cover plate 105 disposed on a side of the OLED display screen 103, and the object 104 to be scanned may be disposed on a side of the glass cover plate 105 away from the OLED display screen 103. The OLED display screen can be protected by the glass cover 105. The electronic device can be brought close to the object 104 to be scanned, so that the object 104 to be scanned can be tightly attached to the side of the glass cover plate 105 of the electronic device, which is far away from the OLED display screen 103. The scan is initiated by a user's scan input.

If the object 104 to be scanned is large in size, N times of emission of the first light rays can be performed, N times of photoelectric conversion are performed to obtain N gray-scale images, and the N gray-scale images are synthesized to obtain a target gray-scale image. Specifically, first, the photoelectric fingerprint ridge-valley mode is entered. Scanning is initiated by pressing a side key or otherwise.

One scan (i.e., one photoelectric conversion) produces one gray-scale image, and position information of the gray-scale image is recorded by 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.

Taking the object 104 to be scanned as a flat-surfaced (e.g., a document) object as an example, as shown in fig. 4, dark (e.g., black) regions absorb more energy and reflect more energy, while light (e.g., white) regions absorb less energy and reflect more energy. The gray-scale original image is generated by sensing the difference of the energy of the light reflected by the color of the object to be scanned (namely, the difference of the absorbed energy of different colors and the difference of the reflected energy, and through photoelectric conversion), so that the gray-scale original image is formed. The functions of scanning the document, identifying the two-dimensional code, identifying the bar code and the like are realized.

In the scanning method provided by the embodiment of the invention, the optical fingerprint module 101 and the OLED display screen 103 of the electronic equipment are used for scanning, the cost is not additionally increased, the method is convenient, fast and rapid, the distortion is reduced, and the user satisfaction and the practicability are greatly improved. The method can be used for document scanning, two-dimensional code recognition, bar code recognition, ceramic and glass flatness inspection, micro crack flaw detection, plant vein rubbing, inscription paperless rubbing and other functions.
