具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
本发明实施例提供的指纹识别方法可以应用于终端设备，其中，所述终端设备包括触控屏以及设置在所述触控屏下的指纹识别模组，所述触控屏包括与所述指纹识别模组对应的指纹识别区域。The fingerprint identification method provided by the embodiment of the present invention can be applied to a terminal device, wherein the terminal device includes a touch screen and a fingerprint identification module disposed under the touch screen, the touch screen includes a touch screen that is connected to the fingerprint Identify the fingerprint identification area corresponding to the module.
指纹识别模组具体可以表现为：光学指纹识别模组、超声波指纹识别模组，但不仅限于此，本发明并不因此限制指纹识别模组的具体表现形式。The fingerprint identification module can specifically be expressed as: an optical fingerprint identification module and an ultrasonic fingerprint identification module, but not limited to this, and the present invention does not limit the specific expression form of the fingerprint identification module.
指纹识别区域可以是触控屏中的部分区域。例如，如图2所示，终端设备的触控屏上设置有指纹识别区域，该指纹识别区域可以仅覆盖触控屏的一小部分。在使用过程中，用户很难准确的将手指按压在该指纹识别区域内，从而提升了指纹识别过程的难度。The fingerprint recognition area may be a part of the touch screen. For example, as shown in FIG. 2 , the touch screen of the terminal device is provided with a fingerprint recognition area, and the fingerprint recognition area may only cover a small part of the touch screen. During use, it is difficult for the user to accurately press the finger in the fingerprint identification area, thereby increasing the difficulty of the fingerprint identification process.
在实际应用中，终端设备可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)、计算机或笔记本电脑等能够进行指纹识别的终端设备，且指纹识别区域设置于终端设备的触控屏内。In practical applications, the terminal device may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (PDA for short), a mobile Internet Device (MID) , a wearable device (Wearable Device), a computer or a notebook computer and other terminal devices capable of fingerprint identification, and the fingerprint identification area is set in the touch screen of the terminal device.
需要说明的是，本发明实施例提供的指纹识别方法可以应用于终端设备的灭屏场景，也可以应用于终端设备的亮屏场景。例如：在手机的亮屏状态下，若采用指纹识别的方式进行支付验证，则可以获取手指与指纹识别区域的距离，在该距离减小至第一预设距离的情况下，显示所述指纹识别区域，以便用户可以在该区域内按压指纹。或者，在手机的灭屏状态下，可以在手指与指纹识别区域的距离减小至第一预设距离的情况下，显示所述指纹识别区域，以便用户可以在该区域内按压指纹进行屏幕解锁操作。It should be noted that the fingerprint identification method provided by the embodiment of the present invention can be applied to a screen-off scenario of a terminal device, and can also be applied to a screen-on scenario of the terminal device. For example: when the screen of the mobile phone is on, if fingerprint recognition is used for payment verification, the distance between the finger and the fingerprint recognition area can be obtained, and when the distance is reduced to the first preset distance, the fingerprint is displayed. Identify the area so that the user can press the fingerprint in that area. Alternatively, when the screen of the mobile phone is off, the fingerprint recognition area can be displayed when the distance between the finger and the fingerprint recognition area is reduced to the first preset distance, so that the user can press the fingerprint in this area to unlock the screen operate.
请参见图1，图1是本发明实施例提供的指纹识别方法的流程图之一。如图1所示，本发明实施例的指纹识别方法可以包括以下步骤：Please refer to FIG. 1. FIG. 1 is one of the flowcharts of a fingerprint identification method provided by an embodiment of the present invention. As shown in FIG. 1 , the fingerprint identification method according to the embodiment of the present invention may include the following steps:
步骤101、获取操作体与所述指纹识别区域之间的目标距离。Step 101: Obtain the target distance between the operating body and the fingerprint identification area.
在实际应用中，目标距离可以是：所述操作体与所述指纹识别区域之间的垂直距离，或者，所述操作体与所述指纹识别区域之间的直线距离，具体可根据实际情况决定，本发明实施例对此不做具体限定。In practical applications, the target distance may be: the vertical distance between the operating body and the fingerprint recognition area, or the straight-line distance between the operating body and the fingerprint recognition area, which may be determined according to the actual situation , which is not specifically limited in this embodiment of the present invention.
在本发明实施例中，操作体可以是人体的任一操作部位，例如：手指、手腕等。当然，其还可以是电容笔等设备或者部件，在此不做具体限定。In this embodiment of the present invention, the operating body may be any operating part of the human body, such as fingers, wrists, and the like. Of course, it may also be a device or component such as a capacitive pen, which is not specifically limited here.
步骤102、在所述目标距离小于或者等于第一预设距离的情况下，显示所述指纹识别区域。Step 102: Display the fingerprint identification area when the target distance is less than or equal to a first preset distance.
其中，所述第一预设距离可以根据用户的使用习惯进行设定，例如：设定为3厘米(cm)。The first preset distance may be set according to the user's usage habits, for example, set to 3 centimeters (cm).
具体实现时，所述显示所述指纹识别区域可以表现为突出显示所述指纹识别区域，例如：视觉增强显示所述指纹识别区域。In a specific implementation, the displaying of the fingerprint identification area may be represented as highlighting the fingerprint identification area, for example, displaying the fingerprint identification area by visual enhancement.
进一步地，可以通过以下方式视觉增强显示所述指纹识别区域：Further, the fingerprint recognition area can be visually enhanced and displayed in the following manner:
改变所述指纹识别区域的亮度；或者，changing the brightness of the fingerprint identification area; or,
显示动画；或者，show animation; or,
显示指纹识别区域的边界。Displays the boundaries of the fingerprint recognition area.
需要说明的是，除了上述列举的方式外，所述视觉增强显示所述指纹识别区域还可通过其他任意可以使用户获知指纹识别区域的方式，在此不做具体限定。It should be noted that, in addition to the manners listed above, the visually enhanced display of the fingerprint identification area may also use any other manner that enables the user to know the fingerprint identification area, which is not specifically limited herein.
通过本步骤，终端设备可以在用户的手指靠近屏幕时，显示指纹识别区域。这样，不仅可以使得用户能够准确的在该区域内输入指纹，提高指纹识别的效率，进一步地，相比于现有技术，还可以避免终端设备在不需要进行指纹识别操作的情况下显示指纹识别区域，从而可以降低终端设备的耗电量，进而可以降低终端设备的能耗。Through this step, the terminal device can display the fingerprint identification area when the user's finger is close to the screen. In this way, not only can the user be able to accurately input fingerprints in this area, and the efficiency of fingerprint recognition can be improved, further, compared with the prior art, it can also be avoided that the terminal device displays fingerprint recognition without the need for fingerprint recognition operations. area, so that the power consumption of the terminal device can be reduced, thereby reducing the power consumption of the terminal device.
在本发明实施例中，终端设备的触控屏包括与所述指纹识别模组对应的指纹识别区域，获取操作体与所述指纹识别区域之间的目标距离；在所述目标距离小于或者等于第一预设距离的情况下，显示所述指纹识别区域。可见，本发明实施例的终端在检测到操作体靠近指纹识别区域的情况下，才显示该指纹识别区域，从而相比于现有技术可以缩短显示指纹识别区域的时长，进而可以降低终端设备的能耗。In the embodiment of the present invention, the touch screen of the terminal device includes a fingerprint identification area corresponding to the fingerprint identification module, and the target distance between the operating body and the fingerprint identification area is obtained; when the target distance is less than or equal to In the case of the first preset distance, the fingerprint identification area is displayed. It can be seen that the terminal according to the embodiment of the present invention displays the fingerprint identification area only when it detects that the operating body is close to the fingerprint identification area, thereby shortening the duration of displaying the fingerprint identification area compared to the prior art, thereby reducing the time required for the terminal device to be displayed. energy consumption.
参见图3，图3是本发明实施例提供的指纹识别方法的流程图之二。本实施例与上述实施例的主要区别在于，对所述在所述目标距离小于或者等于第一预设距离的情况下，显示所述指纹识别区域作了进一步限定，具体为：在所述目标距离小于或者等于所述第一预设距离且大于第二预设距离的情况下，显示所述指纹识别区域，其中，所述第二预设距离小于所述第一预设距离；另外，所述显示所述指纹识别区域之后，对所述指纹识别方法作了进一步限定，具体为：在所述目标距离减小至小于或者等于第二预设距离的情况下，控制所述指纹识别模组对所述操作体进行指纹识别。Referring to FIG. 3, FIG. 3 is a second flowchart of a fingerprint identification method provided by an embodiment of the present invention. The main difference between this embodiment and the above-mentioned embodiment is that the display of the fingerprint identification area when the target distance is less than or equal to the first preset distance is further limited, specifically: when the target distance is less than or equal to the first preset distance When the distance is less than or equal to the first preset distance and greater than the second preset distance, the fingerprint identification area is displayed, wherein the second preset distance is less than the first preset distance; After the fingerprint identification area is displayed as described above, the fingerprint identification method is further limited, specifically: when the target distance is reduced to less than or equal to a second preset distance, controlling the fingerprint identification module Fingerprint recognition is performed on the operating body.
如图3所示，本发明实施例的指纹识别方法具体可以包括以下步骤：As shown in FIG. 3 , the fingerprint identification method according to the embodiment of the present invention may specifically include the following steps:
步骤301、获取操作体与所述指纹识别区域之间的目标距离。Step 301: Obtain the target distance between the operating body and the fingerprint identification area.
需要说明的是，本步骤与上述方法实施例中的步骤101相同，具体可参考步骤101的相关描述，为避免重复，在此不再赘述。It should be noted that this step is the same as
步骤302、在所述目标距离小于或者等于所述第一预设距离且大于第二预设距离的情况下，显示所述指纹识别区域，其中，所述第二预设距离小于所述第一预设距离。Step 302: Display the fingerprint identification area when the target distance is less than or equal to the first preset distance and greater than a second preset distance, wherein the second preset distance is smaller than the first preset distance preset distance.
步骤303、在所述目标距离减小至小于或者等于第二预设距离的情况下，控制所述指纹识别模组对所述操作体进行指纹识别。Step 303: Control the fingerprint recognition module to perform fingerprint recognition on the operating body when the target distance is reduced to less than or equal to a second preset distance.
具体实现时，所述控制所述指纹识别模组对所述操作体进行指纹识别，可以包括：启动指纹识别模组。进一步地，所述控制所述指纹识别模组对所述操作体进行指纹识别还可以包括：控制指纹识别模组或者屏幕发光，或者控制指纹识别模组发超声波。更进一步地所述控制所述指纹识别模组对所述操作体进行指纹识别，还可以包括：获取指纹信息。这样，可以避免在操作体触控到触控屏时才开始开启指纹识别模组和获取指纹信息而延长了指纹识别过程的时间长度。当然，所述控制所述指纹识别模组对所述操作体进行指纹识别的具体过程可以根据指纹识别模组的原理进行改变。During specific implementation, the controlling the fingerprint identification module to perform fingerprint identification on the operating body may include: starting the fingerprint identification module. Further, the controlling the fingerprint identification module to perform fingerprint identification on the operating body may further include: controlling the fingerprint identification module or the screen to emit light, or controlling the fingerprint identification module to emit ultrasonic waves. Further, controlling the fingerprint identification module to perform fingerprint identification on the operating body may further include: acquiring fingerprint information. In this way, it can be avoided that the fingerprint identification module is turned on and the fingerprint information is acquired only when the operating body touches the touch screen, which prolongs the time length of the fingerprint identification process. Certainly, the specific process of controlling the fingerprint recognition module to perform fingerprint recognition on the operating body can be changed according to the principle of the fingerprint recognition module.
例如，在所述指纹识别模组为光学指纹模组，且在所述目标距离小于或者等于第一预设距离且大于所述第二预设距离的情况下，控制所述指纹识别区域的亮度调整为第一亮度值；在所述目标距离减小至小于或者等于第二预设距离时，将所述指纹识别区域中的目标区域的亮度调整为第二亮度值，其中，所述第二亮度值大于所述第一亮度值，以便第二亮度值的光线能够照亮操作体，从而使光学指纹模组采集到更加清晰的指纹图像，并在操作体触控到触控屏时，将采集的指纹图像与预存的指纹信息进行匹配，以确定指纹识别是否通过验证。For example, when the fingerprint recognition module is an optical fingerprint module, and the target distance is less than or equal to the first preset distance and greater than the second preset distance, the brightness of the fingerprint recognition area is controlled Adjust to a first brightness value; when the target distance is reduced to less than or equal to a second preset distance, adjust the brightness of the target area in the fingerprint identification area to a second brightness value, wherein the second The brightness value is greater than the first brightness value, so that the light with the second brightness value can illuminate the operating body, so that the optical fingerprint module can collect a clearer fingerprint image, and when the operating body touches the touch screen, the The collected fingerprint image is matched with the pre-stored fingerprint information to determine whether the fingerprint identification passes the verification.
具体实现时，可以至少通过以下两种方式将目标区域的亮度调整为第二亮度值：方式一，是调整触控屏在目标区域内的显示亮度；方式二，通过设置于触控屏下的光学指纹识别模组发光，使所述目标区域的亮度达到所述第二亮度值。During specific implementation, the brightness of the target area can be adjusted to the second brightness value in at least the following two ways: the first way is to adjust the display brightness of the touch screen in the target area; the second way is to adjust the display brightness of the touch screen in the target area; The optical fingerprint identification module emits light, so that the brightness of the target area reaches the second brightness value.
其中，第二亮度值可以理解为：指纹识别模组能够采集到清晰指纹图像的最低门限值。也就是说，若目标区域的亮度低于所述第二亮度值，指纹识别模组利用采集到的指纹图像进行指纹识别时，指纹识别的通过率较低。第二亮度值的具体数值可以根据光学指纹识别模组的需求，以及所述目标区域的位置确定。Wherein, the second brightness value can be understood as: the minimum threshold value at which the fingerprint identification module can collect a clear fingerprint image. That is to say, if the brightness of the target area is lower than the second brightness value, when the fingerprint identification module uses the collected fingerprint image to perform fingerprint identification, the pass rate of fingerprint identification is low. The specific value of the second brightness value can be determined according to the requirements of the optical fingerprint identification module and the position of the target area.
优选的，所述目标区域为所述操作体在所述指纹识别区域内的正投影区域。这样，可以在所述目标区域的亮度调整为第二亮度值的情况下，使第二亮度值的光线照射至操作体上，以使光学指纹识别模组识别到的指纹图像更加清晰，从而提升了所述指纹识别方法的通过率。Preferably, the target area is an orthographic projection area of the operating body in the fingerprint recognition area. In this way, when the brightness of the target area is adjusted to the second brightness value, the light of the second brightness value can be irradiated on the operating body, so that the fingerprint image recognized by the optical fingerprint recognition module is clearer, thereby improving the the pass rate of the fingerprint identification method.
本实施方式中，可以在所述目标距离小于或者等于第一预设距离且大于所述第二预设距离的情况下，控制所述指纹识别区域的亮度调整为第一亮度值，通过亮度值比较低的第一亮度值提醒用户该指纹识别区域的位置，避免指纹识别区域的亮度过高而造成电量消耗过大；另外，在目标距离减小至小于或者等于第二预设距离时，控制目标区域的亮度调整为第二亮度值，以使指纹识别模组获取到更加清晰的指纹图像，提升了指纹识别方法的通过率和准确率。In this embodiment, when the target distance is less than or equal to the first preset distance and greater than the second preset distance, the brightness of the fingerprint identification area can be controlled to be adjusted to a first brightness value, and the brightness value can be adjusted by the brightness value. The relatively low first brightness value reminds the user of the position of the fingerprint identification area, so as to avoid excessive power consumption caused by the high brightness of the fingerprint identification area; in addition, when the target distance is reduced to less than or equal to the second preset distance, the control The brightness of the target area is adjusted to the second brightness value, so that the fingerprint identification module can obtain a clearer fingerprint image, which improves the pass rate and accuracy of the fingerprint identification method.
进一步地，在检测到目标距离小于或者等于第二预设距离之后，若操作体离开指纹识别区域，即所述目标距离增大至大于所述第二预设距离，所述目标区域的亮度可以恢复至所述第一亮度，或者在所述目标距离增大至大于所述第一预设距离之后，不再显示所述指纹识别区域，即灭屏状态下恢复至黑屏，亮屏状态下显示常规的界面。这样，可以在不需要进行指纹识别时，不再显示所述指纹识别区域或者不再高亮显示所述目标区域，以节省终端设备的电量。Further, after detecting that the target distance is less than or equal to the second preset distance, if the operator leaves the fingerprint recognition area, that is, the target distance increases to be greater than the second preset distance, the brightness of the target area can be adjusted. Return to the first brightness, or after the target distance increases to be greater than the first preset distance, the fingerprint recognition area is no longer displayed, that is, the screen is turned off and the screen is restored to a black screen, and the screen is displayed when the screen is on. Regular interface. In this way, when fingerprint identification is not required, the fingerprint identification area is no longer displayed or the target area is no longer highlighted, so as to save the power of the terminal device.
在实际应用中，所述第一预设距离和所述第二预设距离可以根据用户的需求进行设置。以下以操作体表现为手指，且终端设备表现为手机的实施方式，进行实示例说明。In practical applications, the first preset distance and the second preset distance may be set according to user requirements. The following is an example of an embodiment in which the operating body is represented as a finger, and the terminal device is represented as a mobile phone.
例如，如图4至图7所示的指纹识别方法的应用场景图，本实施例中，第一预设距离为3cm，第二预设距离为5毫米(mm)。其中，图4表示手指与指纹识别区域之间的距离小于或者等于3cm，即所述目标距离小于或者等于第一预设距离，此时，终端设备呈如图5所示的状态，具体表现为：显示所述指纹识别区域。For example, in the application scenario diagrams of the fingerprint identification method shown in FIG. 4 to FIG. 7 , in this embodiment, the first preset distance is 3 cm, and the second preset distance is 5 millimeters (mm). 4 shows that the distance between the finger and the fingerprint recognition area is less than or equal to 3cm, that is, the target distance is less than or equal to the first preset distance. At this time, the terminal device is in the state shown in FIG. 5, which is specifically expressed as : Display the fingerprint recognition area.
若手指进一步靠近指纹识别区域，达到如图6所示的手指与指纹识别区域之间的距离小于或者等于5mm，即所述目标距离小于或者等于第二预设距离的情况下，终端设备呈如图7所示的状态，具体表现为：控制目标区域的亮度调整为第二亮度值，并开启指纹识别模组。If the finger is further close to the fingerprint recognition area, and the distance between the finger and the fingerprint recognition area as shown in Figure 6 is less than or equal to 5mm, that is, when the target distance is less than or equal to the second preset distance, the terminal device will display as follows The state shown in FIG. 7 is specifically expressed as: the brightness of the control target area is adjusted to the second brightness value, and the fingerprint identification module is turned on.
本实施例中的指纹识别方法，可以在手指与指纹识别区域之间的距离减小至小于或者等于5mm时，将目标区域的亮度调整为第二亮度值，并开启指纹识别模组，以在手指触控指纹识别区域之前，获取指纹信息，提升指纹识别的通过率和效率。In the fingerprint identification method in this embodiment, when the distance between the finger and the fingerprint identification area is reduced to less than or equal to 5 mm, the brightness of the target area can be adjusted to the second brightness value, and the fingerprint identification module can be turned on to Before the finger touches the fingerprint recognition area, the fingerprint information is obtained to improve the pass rate and efficiency of fingerprint recognition.
本实施例中，图4与图6中标注的手指中到触控屏之间的距离即为所述目标距离，表示手指到触控屏中指纹识别区域的垂直距离。In this embodiment, the distance between the finger and the touch screen marked in FIG. 4 and FIG. 6 is the target distance, which represents the vertical distance from the finger to the fingerprint recognition area in the touch screen.
本实施例中，目标区域为所述手指在指纹识别区域内的正投影区域，在具体应该用中，所述目标区域还可以是整个触控屏或者整个指纹识别区域等，在此不作具体限定。In this embodiment, the target area is the orthographic projection area of the finger in the fingerprint recognition area. In specific applications, the target area may also be the entire touch screen or the entire fingerprint recognition area, which is not specifically limited here. .
在本发明实施例中，还可以采用两级接近检测传感器检测的方式对所述目标距离进行检测，即采用两种不同的距离检测装置对所述目标距离进行检测。In this embodiment of the present invention, the target distance may also be detected by a two-stage proximity detection sensor detection method, that is, two different distance detection devices are used to detect the target distance.
作为一种可选的实施方式，所述终端设备还包括第一距离检测传感器和第二距离检测传感器，所述第一距离检测传感器的运行功耗低于所述第二距离检测传感器的运行功耗；As an optional implementation manner, the terminal device further includes a first distance detection sensor and a second distance detection sensor, and the operation power consumption of the first distance detection sensor is lower than that of the second distance detection sensor. consume;
所述获取操作体与所述指纹识别区域之间的目标距离，包括：The acquisition of the target distance between the operating body and the fingerprint identification area includes:
通过所述第一距离检测传感器检测操作体与所述指纹识别区域之间的目标距离；Detect the target distance between the operating body and the fingerprint recognition area by using the first distance detection sensor;
在所述第一距离检测传感器检测到的目标距离小于或等于第一预设距离的情况下，通过所述第二距离检测传感器检测所述操作体与所述指纹识别区域之间的目标距离。When the target distance detected by the first distance detection sensor is less than or equal to the first preset distance, the target distance between the operating body and the fingerprint recognition area is detected by the second distance detection sensor.
其中，在操作体与指纹识别区域相隔较远的情况下，即目标距离大于所述第一预设距离的情况下，控制第一距离检测传感器处于运行状态，第二距离检测传感器处于关闭状态。在具体实现中，可以每间隔一个单位时间，通过第一距离检测传感器检测一次操作体与指纹识别区域之间的距离，直至所述目标距离减小至第一预设距离的情况下，开启第二距离检测传感器，并关闭所述第一距离检测传感器，以通过第二距离检测传感器对所述目标距离进行检测。本实施方式中，所述第一距离检测传感器的运行功耗低于所述第二距离检测传感器的运行功耗，则可以通过耗电量较低的第一距离检测传感器进行长时间的检测，避免耗电量高的第二距离检测传感器长时间运行而消耗大量电量，从而降低了终端设备的耗电量。Wherein, when the operating body is far away from the fingerprint recognition area, that is, when the target distance is greater than the first preset distance, the first distance detection sensor is controlled to be in a running state, and the second distance detection sensor is in an off state. In a specific implementation, the distance between the operating body and the fingerprint identification area may be detected by the first distance detection sensor once every unit time, until the target distance is reduced to the first preset distance, and the first distance is turned on. Two distance detection sensors, and the first distance detection sensor is turned off, so that the target distance is detected by the second distance detection sensor. In this implementation manner, the operating power consumption of the first distance detection sensor is lower than the operating power consumption of the second distance detection sensor, so long-term detection can be performed by the first distance detection sensor with lower power consumption, The second distance detection sensor with high power consumption is prevented from running for a long time and consumes a large amount of power, thereby reducing the power consumption of the terminal device.
在具体实施中，第二距离检测传感器可以具体表现为：终端设备的触控屏或者超声波距离检测装置。该第二距离检测传感器的功耗为毫安级，鉴于其可以检测到操作体触控到触控屏的操作状态，其检测距离较短，从而不能够准确的检测大于第一预设距离的目标距离。In a specific implementation, the second distance detection sensor may be embodied as: a touch screen of the terminal device or an ultrasonic distance detection device. The power consumption of the second distance detection sensor is milliampere. Since it can detect the operation state when the operating body touches the touch screen, its detection distance is short, so it cannot accurately detect the distance greater than the first preset distance. target distance.
另外，由于第一距离检测传感器的能耗低，需要每间隔单位时间进行一次距离检测或者检测距离的范围较宽而造成的距离检测精度第等情况，使其检测精度较低，在目标距离小于第一预设距离的情况下，若使用第一距离检测传感器继续检测所述目标距离，则可能造成不能及时触发指纹识别的问题，从而缩短了指纹识别的时间。In addition, due to the low energy consumption of the first distance detection sensor, distance detection needs to be performed once per unit time or the distance detection accuracy is second due to the wide range of detection distances, so that the detection accuracy is low, and when the target distance is less than In the case of the first preset distance, if the first distance detection sensor continues to detect the target distance, it may cause a problem that the fingerprint identification cannot be triggered in time, thereby shortening the fingerprint identification time.
在本实施方式下，若第二距离检测传感器采用终端设备本身具有的触控屏，则该终端设备可以包括如图8所示的器件，终端设备具有：中央处理器(Central ProcessingUnit，CPU)、触控屏驱动电路、触控屏、接近检测驱动电路、屏下接近检测线圈(也可以称之为距离检测线圈)、有机发光二极管(Organic Light-Emitting Diode，OLED)屏幕、屏幕指纹模组(即指纹识别模组)。In this implementation manner, if the second distance detection sensor adopts the touch screen of the terminal device itself, the terminal device may include the device shown in FIG. 8 , and the terminal device has: a central processing unit (Central Processing Unit, CPU), Touch screen drive circuit, touch screen, proximity detection drive circuit, under-screen proximity detection coil (also called distance detection coil), organic light-emitting diode (Organic Light-Emitting Diode, OLED) screen, screen fingerprint module ( Namely fingerprint recognition module).
其中，接近检测驱动电路用于在CPU的控制下，驱动屏下接近检测线圈检测操作体与指纹识别区域之间的目标距离，并将该目标距离反馈至CPU；在CPU接收到的该目标距离小于或者等于第一预设距离时，向触控屏驱动电路发送控制信息，以使其驱动触控屏显示所述指纹识别区域；在CPU接收到的该目标距离小于或者等于第二预设距离时，向OLED屏幕和屏幕指纹模组分别发送相应的控制信息，以使OLED屏幕在目标区域内的亮度提升，并使屏幕指纹模组启动，以在指纹触控到指纹识别区域之前提前识别指纹信息。Among them, the proximity detection drive circuit is used to drive the proximity detection coil under the screen to detect the target distance between the operating body and the fingerprint recognition area under the control of the CPU, and to feed back the target distance to the CPU; the target distance received by the CPU When it is less than or equal to the first preset distance, send control information to the touch screen drive circuit so that it drives the touch screen to display the fingerprint recognition area; the target distance received by the CPU is less than or equal to the second preset distance When the OLED screen is activated, the corresponding control information is sent to the OLED screen and the screen fingerprint module respectively, so that the brightness of the OLED screen in the target area is increased, and the screen fingerprint module is activated to recognize the fingerprint in advance before the fingerprint touches the fingerprint recognition area. information.
在具体应用中，屏幕指纹模组具体可以是光学指纹识别模组，其可以通过识别到的指纹图像信息获取指纹信息。In a specific application, the on-screen fingerprint module may specifically be an optical fingerprint identification module, which can acquire fingerprint information through the identified fingerprint image information.
在具体应用中，所述屏下接近检测线圈可以是如图9中所示的距离检测线圈，其在触控屏上的投影围绕指纹识别区域。本实施方式中，在手指靠近指纹识别区域的过程中，距离检测线圈检测该手指在触控屏上的正投影是否位于屏下接近检测线圈内，若位于该线圈内则检测手指与线圈围绕区域对应的触控屏之间的垂直距离，在该距离小于预先设置的第一预设距离或者小于第二预设距离时，通过接近检测驱动电路向CPU发送一个触发信息，以触发CPU启动触控屏和屏幕指纹模组执行本发明实施例中与目标距离对应的步骤，实现本发明实施例提到的指纹识别方法中的各个过程。In a specific application, the under-screen proximity detection coil may be a distance detection coil as shown in FIG. 9 , and its projection on the touch screen surrounds the fingerprint recognition area. In this embodiment, when the finger approaches the fingerprint recognition area, the distance detection coil detects whether the orthographic projection of the finger on the touch screen is located in the proximity detection coil under the screen, and if it is located in the coil, it detects the area surrounding the finger and the coil. The vertical distance between the corresponding touch screens, when the distance is less than the preset first preset distance or less than the second preset distance, send a trigger message to the CPU through the proximity detection drive circuit to trigger the CPU to start the touch The screen and the screen fingerprint module execute the steps corresponding to the target distance in the embodiment of the present invention, and implement each process in the fingerprint identification method mentioned in the embodiment of the present invention.
在具体应用中，所述距离检测线圈与所述操作体可形成电容；In a specific application, the distance detection coil and the operating body can form a capacitance;
所述通过所述第一距离检测传感器检测操作体与所述指纹识别区域之间的目标距离，包括：The detecting the target distance between the operating body and the fingerprint identification area by the first distance detection sensor includes:
根据所述电容的电性参数值，确定操作体与所述指纹识别区域之间的目标距离。According to the electrical parameter value of the capacitor, the target distance between the operating body and the fingerprint recognition area is determined.
其中，所述电性参数可以表现为：电容值、电流值或电压值。需要说明的是，当电性参数表现为电流值或电压值时，终端设备可以根据电流值或电压值计算得到电容的电容值。Wherein, the electrical parameter can be expressed as: capacitance value, current value or voltage value. It should be noted that, when the electrical parameter is expressed as a current value or a voltage value, the terminal device can calculate the capacitance value of the capacitor according to the current value or the voltage value.
应理解的是，所述电容的电容值与目标距离负相关，即若所述电容的电容值越大，则所述操作体与所述指纹识别区域之间的距离越小。It should be understood that the capacitance value of the capacitor is negatively correlated with the target distance, that is, if the capacitance value of the capacitor is larger, the distance between the operating body and the fingerprint identification area is smaller.
在实际应用中，一种实现方式中，终端设备可以预先获取电容值与目标距离之间的对应关系。这样，在检测到所述电容的电容值的情况下，通过查找上述对应关系，确定电容值对应的目标距离。In practical applications, in an implementation manner, the terminal device may obtain the correspondence between the capacitance value and the target distance in advance. In this way, when the capacitance value of the capacitor is detected, the target distance corresponding to the capacitance value is determined by searching for the above-mentioned corresponding relationship.
另一种实现方式中，终端设备可以预先获取利用电容值计算目标距离的计算公式。这样，在检测到所述电容的电容值的情况下，可以将该电容值输入至上述计算公式，计算出目标距离。In another implementation manner, the terminal device may obtain in advance a calculation formula for calculating the target distance by using the capacitance value. In this way, when the capacitance value of the capacitor is detected, the capacitance value can be input into the above calculation formula to calculate the target distance.
在应用过程中，若所述指纹识别模组表现为超声波指纹识别模组，可以在所述目标距离减小至小于或者等于第二预设距离时，控制超声波指纹识别模组发射超声波，并通过超声波的传播时间和速度获取指纹信息等。在此对不对控制所述指纹识别模组对所述操作体进行指纹识别的过程进行限定。In the application process, if the fingerprint recognition module is an ultrasonic fingerprint recognition module, when the target distance is reduced to less than or equal to the second preset distance, the ultrasonic fingerprint recognition module can be controlled to emit ultrasonic waves, and the ultrasonic wave can be transmitted through the target distance. Ultrasonic propagation time and speed to obtain fingerprint information and so on. The process of controlling the fingerprint recognition module to perform fingerprint recognition on the operating body is not limited herein.
可见，区别于现有技术中，终端设备只有在检测到操作体对指纹识别模组的触控操作的情况下，才控制指纹识别模组对所述操作体进行指纹识别，本实施例的终端设备在所述目标距离减小至小于或者等于第二预设距离的情况下，即可控制所述指纹识别模组对所述操作体进行指纹识别，从而实现在用户手指接触触控屏之前即开始打光或者发射超声波，以及开启指纹识别模组，缩短了用户触控屏幕后的指纹识别时间，从而提升了指纹识别的效率。It can be seen that, different from the prior art, the terminal device controls the fingerprint recognition module to perform fingerprint recognition on the operating body only when it detects the touch operation of the operating body on the fingerprint recognition module. When the target distance is reduced to less than or equal to the second preset distance, the device can control the fingerprint recognition module to perform fingerprint recognition on the operating body, so as to realize that the user's finger touches the touch screen immediately before the touch screen. Starting to light or emit ultrasonic waves, as well as turning on the fingerprint recognition module, shortens the fingerprint recognition time after the user touches the screen, thereby improving the efficiency of fingerprint recognition.
需要说明的是，无论所述指纹识别模组是光学指纹识别模组还是超声波指纹识别模组，在操作体与指纹识别区域之间的目标距离小于第二预设距离的情况下，提前对操作体进行打光或者提前向操作体发射超声波，并提前启动指纹识别模组。这样，在目标距离小于第二预设距离的时间点到操作体触控指纹识别区域的时间点之间，将具有一定的时间长度，在该时间长度内，指纹识别模组可以进行多次指纹信息采集，即采集多帧指纹识别信息，并在操作体触控到指纹识别区域时，选取最清晰或者最精确的一个指纹信息进行指纹验证，以在减少指纹识别的时间长度，同时还能够提升指纹识别和指纹验证过程的精确度。It should be noted that, no matter whether the fingerprint identification module is an optical fingerprint identification module or an ultrasonic fingerprint identification module, when the target distance between the operating body and the fingerprint identification area is less than the second preset distance, the operation is performed in advance. The body is illuminated or ultrasonic waves are emitted to the operator in advance, and the fingerprint recognition module is activated in advance. In this way, there will be a certain length of time between the time point when the target distance is less than the second preset distance and the time point when the operator touches the fingerprint recognition area. Within this time length, the fingerprint recognition module can perform multiple fingerprinting Information collection, that is, to collect multiple frames of fingerprint identification information, and when the operator touches the fingerprint identification area, select the clearest or most accurate fingerprint information for fingerprint verification, so as to reduce the time length of fingerprint identification and improve the Accuracy of fingerprint identification and fingerprint verification process.

In this way, when the user brings his finger close to the fingerprint identification area, the user can be informed of the location of the fingerprint identification area, so as to reduce the difficulty of the fingerprint identification process, and when the user's finger is further close to the fingerprint identification area, the fingerprint identification module can be turned on in advance for fingerprint identification. In order to reduce the fingerprint identification time after touching the fingerprint identification area, the fingerprint identification time is shortened and the efficiency of the fingerprint identification method is improved.
