Fig. 3 is a flowchart illustrating a method of controlling a terminal device to scan a file according to an exemplary embodiment in which a file appearing in a fingerprint sensing area includes: an external file; as shown in fig. 3, the method is applied to a terminal device, and includes the following steps S201-S204:
in step S201, a scan instruction is received; the scan instruction instructs to scan a file that appears in the fingerprint sensing area.
In step S202, the light emitting device is controlled to emit a light signal to the fingerprint sensing area.
In step S203, the optical fingerprint identification module is controlled to receive the light signal reflected by the document.
In step S204, the optical fingerprint identification module is controlled to obtain an image of the document according to the optical signal reflected by the document.
When external file is required to be scanned, the surface of the external file to be scanned is placed in a fingerprint sensing area of the terminal device, then, the light emitting device is controlled to emit light signals to the fingerprint sensing area, at the moment, the light signals are reflected back to the inside of the terminal device due to the fact that the external file shields the light signals, then the optical fingerprint identification module is controlled to receive the light signals reflected by the external file, and when the optical fingerprint identification module receives the light signals reflected by the external file, images of the file can be obtained based on the light signals reflected by the external file.
In one implementation, due to the limited sensing area of the fingerprint sensing area of the terminal device, when the external file size is greater than or equal to the sensing area of the fingerprint sensing area, a customized positioning tool may be used, as shown in fig. 4, and the positioning tool includes: as shown in fig. 5, when a document needs to be scanned, the scanned document can be placed at the scanning start position scale first, and the document placed under the scale is placed in order to avoid that part of the content of the document cannot be scanned, then as shown in fig. 6, the terminal device is placed at the scanning start position as shown in fig. 6, the fingerprint sensing area is located between the scanning start position scale and the line change scale 1, at this time, the scanning function can be started, the document content corresponding to the fingerprint sensing area can be scanned, but because the size of the document is large, the document on the right side of the scanning fingerprint sensing area can not be scanned, so that the terminal device can be translated to the right side during scanning, so that the content on the right side of the file can be covered by the fingerprint sensing area, after the line is scanned, the terminal equipment is picked up, then the transverse rod is translated downwards, and as the transposition clamping groove is arranged on the longitudinal rod, the transverse rod is moved to the next clamping groove position, as shown in fig. 7, the fingerprint sensing area is positioned between the line change scale 1 and the line change scale 2, and then the file content on the line can be scanned. By setting the tool as shown in fig. 4, the initial position of scanning can be located to start line-by-line scanning; and when line feed scanning is carried out, the accurate distance of each downward movement is given, so that the scanning reliability is improved.

In a3, when the moving speed of the terminal device is detected to be greater than or equal to the preset speed, a prompt message is output, and the prompt message prompts to slow down the moving speed of the terminal device.
When scanning is carried out, the size of the file is larger than or equal to the size of the fingerprint sensing area, the terminal equipment can be moved, so that the whole content of the file can be scanned by the fingerprint scanning area, but when the terminal equipment is moved, if the moving speed is too high, the optical fingerprint identification module cannot acquire a reliable optical signal, so that the image of the file cannot be acquired, therefore, in the process of moving the terminal equipment, the mobile phone gyroscope and the gravity sensor can be simultaneously utilized to measure the moving speed of the terminal equipment, when the moving speed is smaller than the preset speed, the optical fingerprint identification module can acquire the reliable optical signal, and the optical fingerprint identification module can be controlled to acquire the optical signal corresponding to the file in the fingerprint sensing area; when the moving speed is greater than or equal to the preset speed, the optical fingerprint identification module cannot acquire a reliable optical signal, prompt information can be output at the moment, the prompt information prompts that the moving speed of the terminal equipment is reduced, and after the user receives the prompt information, the speed of the mobile terminal equipment can be reduced.
