The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
At present, a hole is dug in the whole cover plate glass, and a fingerprint sensor is arranged in the hole, so that the strength of the whole cover plate glass is reduced, and the design of the appearance of a terminal is limited.
In order to solve the above problems, in this embodiment, the fingerprint sensor may be disposed under the touch screen, and when the terminal detects that the finger touch position is in the fingerprint acquisition area of the touch screen, the fingerprint sensor is controlled to start fingerprint scanning; the fingerprint information of the finger in the fingerprint collection area is obtained through the fingerprint sensor in a scanning mode, here, the area of the fingerprint collection area is larger than the actual fingerprint area, a user can conveniently and accurately input the fingerprint information in the fingerprint collection area of the touch screen, touch control and fingerprint collection in the touch screen are achieved, touch control and fingerprint collection functions are integrated in the touch screen, cover plate glass is not affected, the appearance design of the terminal is facilitated, and the terminal can easily obtain complete fingerprint information in the fingerprint collection area after the finger is detected.
Fig. 1 is a flowchart illustrating a fingerprint collection method according to an exemplary embodiment, where as shown in fig. 1, the fingerprint collection method is used in a device such as a terminal, and includes the following steps 101 and 102:
in step 101, when detecting that the finger touch position is in the fingerprint acquisition area of the touch screen, controlling a fingerprint sensor to start fingerprint scanning; the area of the fingerprint acquisition area is larger than a preset area threshold.
In step 102, fingerprint information of the finger is obtained through fingerprint scanning of the fingerprint sensor.
Here, fingerprint sensor is the key device that realizes fingerprint automatic acquisition, and this disclosure adopts the fingerprint collection scheme in the face, sets up fingerprint sensor under the touch-sensitive screen of terminal, and this fingerprint sensor can gather the fingerprint information in the fingerprint collection region of touch-sensitive screen, and this fingerprint collection region is the region that this fingerprint sensor can gather fingerprint information promptly. For example, fig. 2 is a schematic diagram illustrating a terminal capable of implementing a fingerprint collection method according to an exemplary embodiment, and as shown in fig. 2, a fingerprint sensor (not shown in the figure) is disposed under the touch screen 20 of the terminal 2, and the fingerprint sensor is capable of collecting fingerprint information in a fingerprint collection area 201.
Here, the touch screen may detect a touch position of a finger of a user, and when the terminal needs to collect fingerprint information for user identification or fingerprint identification such as unlocking decryption, the user may place the finger in a fingerprint collection area of the touch screen, and at this time, the touch screen may detect the finger touch position of the finger, for example, an intersection point of two adjacent frames on the touch screen may be set as an origin point, one frame of the two adjacent frames may be located on an x axis, and an adjacent frame in a direction perpendicular to the x axis may be set as a y axis, and the finger touch position detected by the touch screen may be a coordinate value (x1, y 1). If the finger touch position is in the fingerprint acquisition area of the touch screen, the user is indicated to put the finger in the fingerprint acquisition area for the terminal to acquire the fingerprint, and at the moment, the terminal can control the fingerprint sensor to perform fingerprint scanning on the fingerprint acquisition area to obtain the fingerprint information of the finger.
It should be noted here that, the area of the fingerprint collecting area of the fingerprint sensor is usually small, and about 15 mm 17 mm, it is enough to ensure that a complete fingerprint can be collected, but when the in-plane fingerprint scheme is adopted, a hole is not dug on the cover glass to limit the fingerprint collecting area so as to facilitate user input, so the area of the fingerprint collecting area of the terminal touch screen is large and larger than a preset area threshold, and the preset area threshold is larger than the actual fingerprint area when the user inputs the fingerprint, such as 30 mm. Therefore, the area of the fingerprint acquisition area is set to be larger, so that when a user inputs fingerprint information, the fingerprint information can be accurately input in the fingerprint acquisition area with a larger area, and the fingerprint sensor can also scan complete fingerprint information, thereby improving the accuracy of fingerprint identification.
According to the embodiment, the fingerprint sensor can be arranged below the touch screen, and when the terminal detects that the finger touch position is in the fingerprint acquisition area of the touch screen, the fingerprint sensor is controlled to start fingerprint scanning; the fingerprint information of the finger in the fingerprint collection area is obtained through the fingerprint sensor in a scanning mode, here, the area of the fingerprint collection area is larger than the actual fingerprint area, a user can conveniently and accurately input the fingerprint information in the fingerprint collection area of the touch screen, touch control and fingerprint collection in the touch screen are achieved, touch control and fingerprint collection functions are integrated in the touch screen, cover plate glass is not affected, the appearance design of the terminal is facilitated, and the terminal can easily obtain complete fingerprint information in the fingerprint collection area after the finger is detected.
In a possible implementation, step 101 in the above fingerprint acquisition method may be implemented as the following steps a1 and a 2.
In step a1, a target fingerprint scanning area corresponding to the finger touch position is determined, wherein the target fingerprint scanning area is a partial area in the fingerprint acquisition area.
In step a2, the fingerprint sensor is controlled to start fingerprint scanning of the target fingerprint scanning area.
Here, because the area of the fingerprint acquisition area is relatively large, when a user touches the fingerprint acquisition area, the contact area between the finger and the screen is only a partial area in the fingerprint acquisition area and does not occupy all the area in the fingerprint acquisition area, so that when the terminal acquires fingerprint information, the terminal does not need to scan the whole fingerprint acquisition area, and only needs to scan the partial area in the fingerprint acquisition area to obtain the fingerprint information.
Here, when detecting that the finger touch position is in the fingerprint collection area of the touch screen, the terminal may first determine a target fingerprint scanning area corresponding to the finger touch position, for example, the terminal may detect a contact area between the finger and the fingerprint collection area of the touch screen, and take the contact area as the target fingerprint scanning area, where the target fingerprint scanning area is a partial area in the fingerprint collection area; therefore, the terminal only needs to control the fingerprint sensor to start fingerprint scanning of the target fingerprint scanning area, and the fingerprint information of the finger can be obtained.
According to the embodiment, the target fingerprint scanning area corresponding to the finger touch position can be determined, the fingerprint sensor is controlled to start fingerprint scanning of the target fingerprint scanning area only, fingerprint scanning of the whole fingerprint acquisition area is not started, and power consumption of the terminal is reduced.
In a possible implementation, the step a1 in the fingerprint acquisition method can be implemented as the following step a 11.
In step a11, determining an area within the fingerprint acquisition area and within a preset range from the finger touch position as a target fingerprint scanning area.
For example, the finger touch position may be represented by coordinates of the above example, the unit of the x and y axes may be the number of pixels, the terminal detects the finger touch position as coordinates (x1, y1), if the coordinate range of the fingerprint collection area is (x ═ x0, x2, y ═ y0, y 2), and since x0< x1< x2, y0< y1< y2, the terminal determines that the finger touch position is within the fingerprint collection area, at this time, the terminal may determine an area within a preset range of the distance coordinates (x1, y1), that is, a circular area with the distance of a pixels as the center of a circle, and the overlapping area of the circular area and the fingerprint collection area is the fingerprint scanning target area.
Here, after the terminal determines the target fingerprint scanning area, the terminal may control the fingerprint sensor to start fingerprint scanning on the target fingerprint scanning area to obtain fingerprint information in the target fingerprint scanning area.
In this embodiment, it may be determined that an area within the fingerprint acquisition area and within the preset range from the finger touch position is a target fingerprint scanning area, and fingerprint information obtained by the terminal by scanning a fingerprint in the target fingerprint scanning area is sufficient to ensure that the terminal can perform accurate fingerprint identification according to the obtained fingerprint information, thereby ensuring the quality of the obtained fingerprint information.
In one possible embodiment, the fingerprint acquisition area comprises at least two fingerprint scanning areas; step a1 in the above fingerprint acquisition method may be implemented as the following step a 12.
In step a12, a target fingerprint scanning area corresponding to the finger touch position is determined according to a pre-stored correspondence between the touch position and the fingerprint scanning area.
Here, the terminal may divide the fingerprint collection area into at least two fingerprint scanning areas, and adjacent two of the fingerprint scanning areas may partially overlap, and the fingerprint scanning areas may be grouped together to completely cover the fingerprint collection area.
Here, each touch position in the fingerprint acquisition area of the touch screen may correspond to one fingerprint scanning area, one fingerprint scanning area may correspond to a plurality of touch positions, the correspondence may ensure that when the finger touch position of the user is a certain touch position, the fingerprint scanning is performed on the fingerprint scanning area corresponding to the touch position, and the accuracy of subsequent fingerprint identification can be ensured by the acquired fingerprint information, such as the size and quality of a fingerprint pattern.
For example, fig. 3 is a schematic diagram illustrating a corresponding relationship between touch positions and fingerprint scanning areas according to an exemplary embodiment, where, as shown in fig. 3, a position 1 in the fingerprint collection area 30 corresponds to a fingerprint scanning area 301, and a position 2 in the fingerprint collection area 30 corresponds to a fingerprint scanning area 302. When the terminal detects that the finger touch position is position 1, the terminal can determine that the target fingerprint scanning area corresponding to the finger touch position is the fingerprint scanning area 301 according to the pre-stored corresponding relationship between the touch position and the fingerprint scanning area, and when the terminal detects that the finger touch position is position 2, the terminal can determine that the target fingerprint scanning area corresponding to the finger touch position is the fingerprint scanning area 302.
Here, after the terminal determines the target fingerprint scanning area, the terminal may control the fingerprint sensor to start fingerprint scanning on the target fingerprint scanning area to obtain fingerprint information in the target fingerprint scanning area, and since the target fingerprint scanning area is a fingerprint scanning area corresponding to the finger touch position, the terminal controls the fingerprint sensor to scan the fingerprint information obtained when the fingerprint scanning area is scanned, which is sufficient to ensure that a subsequent terminal performs fingerprint identification according to the fingerprint information, and ensures the quality of the obtained fingerprint information.
According to the embodiment, the target fingerprint scanning area corresponding to the finger touch position can be determined according to the corresponding relation between the pre-stored touch position and the fingerprint scanning area, so that no matter how the finger touch position is changed, the fingerprint information obtained by scanning the fingerprint scanning area corresponding to the finger touch position can be ensured to be used for ensuring the subsequent fingerprint identification performance.
In a possible implementation, the fingerprint acquisition method may further include the following step B1.
In step B1, when it is detected that fingerprint collection is required, a prompt pattern is displayed in the fingerprint collection area, where the prompt pattern is used to prompt the location of the fingerprint collection area.
Here, the regional assigned position of setting in the terminal touch-sensitive screen of fingerprint collection, the terminal can be when detecting that needs carry out fingerprint collection if detect that the terminal needs the fingerprint unblock or need open fingerprint encryption file, can show the position that the suggestion pattern reminded user's fingerprint collection region on this fingerprint collection region, and convenience of customers discerns where the fingerprint collection region is, and then accurately is this fingerprint collection regional input.
The terminal can detect that the fingerprint acquisition needs to be carried out by unlocking when the screen is turned off, and at the moment, the terminal can control the fingerprint acquisition area to be in the screen-on state and other areas to be in the screen-off state, so that the user can be prompted to carry out fingerprint input in the area in the screen-on state by displaying the prompt pattern. Or, when the terminal is in a bright screen state and detects that a user opens a certain file or application with encrypted fingerprint, the terminal detects that fingerprint decryption is needed, namely fingerprint acquisition is needed, at the moment, the terminal can display a fingerprint pattern or other patterns in the fingerprint acquisition area, and thus, the user can be prompted to perform fingerprint input in the area in the bright screen state.
This embodiment can be when detecting that needs carry out fingerprint collection the regional position that shows the suggestion pattern and remind user's fingerprint collection area of fingerprint collection, convenience of customers discerns the fingerprint collection is regional where, and then accurately is in this fingerprint collection regional input.
The implementation is described in detail below by way of several embodiments.
