Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. 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.
FIG. 2 is a schematic flow chart diagram illustrating a method of fingerprint identification in accordance with an exemplary embodiment. The method shown in this embodiment may be applied to a terminal, such as a mobile phone, a tablet computer, and the like, where the terminal includes a fingerprint sensor array composed of a plurality of fingerprint sensors, and the fingerprint sensors may be photoelectric sensors, and are used to generate electrical signals according to sensed light.
As shown in fig. 2, the fingerprint identification method of this embodiment may include the following steps:
in step S1, when a range determination command is received, if the sensed area of the fingerprint is larger than a predetermined area, a brightness range is determined according to the brightness of the light sensed by the fingerprint sensor array.
In one embodiment, the range-determining instructions may be input by a user or may be automatically generated when the user performs certain operations.
For example, when the fingerprint of the user is collected for the first time, a range determining instruction can be automatically generated, and when the area sensing the fingerprint of the user is larger than the preset area, the brightness range is determined according to the brightness of the light sensed by the fingerprint sensor array.
For example, after the fingerprint of the user is collected for the first time, the user may input a range determination instruction, so that when the user places a finger in the fingerprint recognition area, the fingerprint of the user is not recognized, but whether the sensed area of the fingerprint is larger than a preset area is determined, and when the sensed area of the fingerprint is larger than the preset area, the luminance range is determined according to the luminance of the light sensed by the fingerprint sensor. After that, the fingerprint of the user may be further recognized, and the operation may be ended.
In one embodiment, the sensed area of the fingerprint may be an area of the fingerprint identification area covered by the finger of the user, wherein the area of the fingerprint identification area covered by the finger of the user may be determined according to the number of fingerprint sensors receiving the light, and the area of the fingerprint identification area covered by the finger of the user may also be determined by the touch sensor.
In one embodiment, the predetermined area may be set as desired, but it is necessary to ensure that when the fingerprint area is larger than the predetermined area, the fingerprint sensor receives much less ambient light than the received light reflected by the fingerprint, for example, the ratio of the number of fingerprint sensors receiving the ambient light to the number of fingerprint sensors receiving the light reflected by the fingerprint is 1:10, and further, the predetermined area may be set to 80% of the area of the fingerprint identification area.
In one embodiment, in the case that the sensed fingerprint area is larger than the preset area, the maximum value and the minimum value of the brightness of the light sensed by the fingerprint sensor may be determined, wherein the maximum value may be used as the upper limit value of the brightness range, and the minimum value may be used as the lower limit value of the brightness range.
In one embodiment, an upper limit value of the luminance range may be set according to the maximum value, and a lower limit value of the luminance range may be set according to the minimum value. For example, the maximum value may be rounded up as the upper limit value of the luminance range, and the minimum value may be rounded down as the lower limit value of the luminance range.
In step S2, upon receiving a fingerprint recognition instruction, a target fingerprint sensor in the fingerprint sensor array is determined in which the brightness of the sensed light is within the brightness range.
In one embodiment, the fingerprinting instructions may be input by the user or may be automatically generated when the user performs certain operations. The fingerprint identification instruction is automatically generated when a user performs certain operations, for example, when the user performs a payment operation, the fingerprint identification instruction can be automatically generated in the step of fingerprint verification of the payment operation.
In one embodiment, the terminal may further include a built-in light source, and the brightness of the light emitted by the built-in light source may be different from the brightness of the ambient light in the environment where the terminal is located, for example, in a sunlight environment, the brightness of the ambient light may be greater than the brightness of the light emitted by the built-in light source.
In step S3, a fingerprint pattern is determined according to the light sensed by the target fingerprint sensor, and fingerprint recognition is performed according to the determined fingerprint pattern.
Similarly to the related art, since the finger of the user does not generally completely cover the light-transmitting opening in the fingerprint identification area when identifying the fingerprint, the fingerprint sensor can receive not only the light emitted from the built-in light source reflected by the fingerprint but also the ambient light. Whereas if the brightness of the ambient light is not within the brightness range (e.g., greater than the upper limit of the brightness range), it is difficult to accurately recognize the fingerprint pattern from the signal generated by the fingerprint sensor receiving the ambient light.
According to an embodiment of the present disclosure, a target fingerprint sensor in which the brightness of the sensed light is within the brightness range may be determined among all fingerprint sensors. And then confirm the fingerprint figure according to the light that target fingerprint sensor sensed, also that is to say confirm the fingerprint figure according to the signal that the fingerprint sensor that receives built-in light source reflection light generated, avoid discerning the fingerprint figure according to the signal that the fingerprint sensor that receives the ambient light generated to guarantee the accuracy of confirming the fingerprint figure.
Figure 3 is a schematic flow diagram illustrating a targeted fingerprint sensor according to one exemplary embodiment. As shown in fig. 3, on the basis of the embodiment shown in fig. 2, the target fingerprint sensor determining that the brightness of the sensed light is within the brightness range in the fingerprint sensor array upon receiving the fingerprint identification command includes:
in step S21, upon receiving a fingerprint identification instruction, determining the brightness of the ambient light in the environment where the terminal is located;
in step S22, if the brightness of the ambient light is greater than a first preset brightness, a target fingerprint sensor in the fingerprint sensor array is determined that the brightness of the sensed light is within the brightness range.
In one embodiment, the terminal may further include a brightness sensor, and the brightness of the ambient light in the environment of the terminal may be sensed by the brightness sensor.
In one embodiment, the first preset brightness may be set as needed, for example, a brightness greater than the maximum value of the brightness of the built-in light source is taken as the first preset brightness, and for example, the average value of the brightness of the sunlight in the morning, at midday and at evening on a sunny day may be calculated as the first preset brightness.
In an embodiment, if the brightness of the ambient light is greater than the first preset brightness, it may be determined that the terminal is located in an environment with higher brightness, and the ambient light irradiates on the fingerprint sensor to have a greater influence on the recognition result of the fingerprint pattern, so that the target fingerprint sensor with the sensed brightness of the light within the brightness range may be determined in the fingerprint sensor array, and the fingerprint pattern may be determined according to the light sensed by the target fingerprint sensor, that is, the fingerprint pattern may be determined only according to a signal generated by the fingerprint sensor receiving the light reflected by the built-in light source, and the fingerprint pattern may be prevented from being recognized according to the signal generated by the fingerprint sensor receiving the ambient light, thereby ensuring the accuracy of determining the fingerprint pattern.
FIG. 4 is a schematic flow chart diagram illustrating another method of fingerprinting in accordance with an exemplary embodiment. As shown in fig. 4, on the basis of the embodiment shown in fig. 3, the fingerprint identification method further includes:
in step S4, if the brightness of the ambient light is less than or equal to a second predetermined brightness, where the second predetermined brightness is less than or equal to the first predetermined brightness, a fingerprint pattern is determined according to the brightness of the light sensed by the fingerprint sensor array.
In an embodiment, the second preset brightness may be set as needed, for example, the second preset brightness is equal to the first preset brightness, and the setting manner of the second preset brightness is the same as the setting manner of the first preset brightness, for example, the second preset brightness is smaller than the first preset brightness, and then the brightness of the light emitted by the built-in light source may be used as the second preset brightness, or the upper limit value of the brightness range may be used as the second preset brightness.
In one embodiment, if the brightness of the ambient light is less than or equal to the second preset brightness, it may be determined that the terminal is in an environment with lower brightness, and the influence of the ambient light on the fingerprint sensor on the recognition result of the fingerprint pattern is small or even negligible.
FIG. 5 is a schematic flow chart diagram illustrating yet another method of fingerprinting in accordance with an exemplary embodiment. As shown in fig. 5, on the basis of the embodiment shown in fig. 2, the method further includes:
in step S5, the range determination instruction is received at the time of or after the fingerprint acquisition.
In one embodiment, the range-determining instructions may be input by a user or may be automatically generated when the user performs certain operations.
For example, when the fingerprint of the user is collected for the first time, a range determining instruction can be automatically generated, and when the area sensing the fingerprint of the user is larger than the preset area, the brightness range is determined according to the brightness of the light sensed by the fingerprint sensor.
For example, after the fingerprint of the user is collected for the first time, the user may input a range determination instruction, so that when the user places a finger in the fingerprint recognition area, the fingerprint of the user is not recognized, but whether the sensed area of the fingerprint is larger than a preset area is determined, and when the sensed area of the fingerprint is larger than the preset area, the luminance range is determined according to the luminance of the light sensed by the fingerprint sensor. After that, the fingerprint of the user may be further recognized, and the operation may be ended.
Optionally, the fingerprint sensor is arranged in and/or outside the display area.
In one embodiment, the fingerprint sensor may be disposed in the display area, for example, may be disposed in an array substrate of the display panel.
In one embodiment, the fingerprint sensor may be arranged outside the display area, for example in the back cover of the terminal, or in a physical key of the terminal.
