具体实施方式Detailed ways
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings.

The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.
目前，只要用户用手指按压在该指纹采集区域，终端就会打开光源，在该指纹采集区域形成一高亮光斑，以便采集指纹信息。目前终端只会在该显示屏的指纹采集区域处形成与该指纹采集区域大小一样的高亮光斑，来采集到该指纹采集区域内的指纹信息，然而，由于用户手指在终端屏幕上的按压面积大小不可控制，该指纹采集区域处的高亮光斑可能无法被手指完全遮挡，而露出来的高亮光斑会很刺眼。At present, as long as the user presses the fingerprint collection area with a finger, the terminal will turn on the light source and form a bright spot in the fingerprint collection area to collect fingerprint information. At present, the terminal only forms a high-brightness light spot with the same size as the fingerprint collection area at the fingerprint collection area of the display screen to collect the fingerprint information in the fingerprint collection area. However, due to the pressing area of the user's finger on the terminal screen The size is uncontrollable, and the highlight spot in the fingerprint collection area may not be completely blocked by the finger, and the exposed highlight spot will be very dazzling.
为了解决上述问题，本实施例可以检测手指按压区域的位置信息；根据所述手指按压区域的位置信息，确定所述手指按压区域与预设的指纹采集区域的重叠区域的位置信息；在根据所述重叠区域的位置信息，确定所述重叠区域在大小上覆盖预设的第一区域时，确定点亮区域，所述点亮区域在所述重叠区域内，为可识别的指纹图像所占的区域；点亮所述点亮区域，获取所述点亮区域内的指纹图像，如此，终端在采集指纹时只会在该点亮区域内形成亮斑，而该点亮区域在用户手指按压区域内，故形成的亮斑就会被用户手指覆盖，不会露出刺眼亮光。In order to solve the above problems, this embodiment can detect the position information of the finger pressing area; according to the position information of the finger pressing area, determine the position information of the overlapping area of the finger pressing area and the preset fingerprint collection area; The position information of the overlapping area is determined, and when it is determined that the overlapping area covers the preset first area in size, the lighting area is determined, and the lighting area is within the overlapping area and is occupied by the recognizable fingerprint image. area; light up the lighted area, and obtain the fingerprint image in the lighted area. In this way, the terminal will only form a bright spot in the lighted area when collecting fingerprints, and the lighted area is in the pressing area of the user's finger. Therefore, the formed bright spots will be covered by the user's fingers and will not reveal dazzling light.
图1是根据一示例性实施例示出的一种指纹采集方法的流程图，如图1所示，该指纹采集方法用于终端中，包括以下步骤101-104：Fig. 1 is a flowchart of a fingerprint collection method according to an exemplary embodiment. As shown in Fig. 1 , the fingerprint collection method used in a terminal includes the following steps 101-104:
在步骤101中，检测手指按压区域的位置信息。In
在步骤102中，根据所述手指按压区域的位置信息，确定所述手指按压区域与预设的指纹采集区域的重叠区域的位置信息。In
在步骤103中，在根据所述重叠区域的位置信息，确定所述重叠区域在大小上覆盖预设的第一区域时，确定点亮区域，所述点亮区域在所述重叠区域内，为可识别的指纹图像所占的区域。In
在步骤104中，点亮所述点亮区域，获取所述点亮区域内的指纹图像。In
这里，本公开中的指纹模组设置在终端显示屏的屏幕下，在需要采集指纹时，终端可以打开指纹模组中的光源，如此该光源发射的入射光可以穿透部分或全部的指纹采集区域，照射至用户的指尖，利用漫反射的现象，使得该指纹模组可以获取一个指纹图像，如此实现指纹采集。Here, the fingerprint module in the present disclosure is set under the screen of the terminal display screen. When fingerprints need to be collected, the terminal can turn on the light source in the fingerprint module, so that the incident light emitted by the light source can penetrate part or all of the fingerprint collection. The area is illuminated to the user's fingertip, and the phenomenon of diffuse reflection is used, so that the fingerprint module can obtain a fingerprint image, thus realizing fingerprint collection.
这里，终端在灭屏状态下可以在显示屏上显示一提示图案来提示用户输入指纹的位置即终端的指纹采集区域，或者在亮屏状态下检测到需要用户输入指纹如某应用或文件需要指纹解锁时，终端也会显示一提示图案来提示用户输入指纹的位置。用户在看到终端上显示的提示图案时，如果用户想要解锁就可以在该提示图案提示的指纹采集区域输入指纹。Here, when the screen is off, the terminal can display a prompt pattern on the display screen to prompt the user to input the location of the fingerprint, that is, the fingerprint collection area of the terminal. When unlocking, the terminal will also display a prompt pattern to prompt the user to input the location of the fingerprint. When the user sees the prompt pattern displayed on the terminal, if the user wants to unlock, he can input a fingerprint in the fingerprint collection area prompted by the prompt pattern.
这里，用户在输入指纹时，由于不同用户的手指大小不同，同一用户的按压位置或按压力度不同，导致用户在显示屏上的手指按压区域不同，终端可以通过触摸屏模组上的触控传感器如压力传感器等来检测用户在终端显示屏上的手指按压区域的位置信息。Here, when a user inputs a fingerprint, due to the different finger sizes of different users and the different pressing positions or pressing strengths of the same user, the user's finger pressing area on the display screen is different. The terminal can use the touch sensor on the touch screen module, such as A pressure sensor, etc., is used to detect the position information of the user's finger pressing area on the terminal display screen.
示例的，图2是根据一示例性实施例示出的一种指纹采集时终端上各区域的图示示意图，如图2所示，预设的指纹采集区域21是终端2的指纹模组可以采集到指纹信息的有效区域，位于终端显示屏的固定位置处，手指按压区域22为用户手指触摸终端显示屏时，手指覆盖在显示屏的区域，终端检测到该手指按压区域22的位置信息后可以根据所述手指按压区域22的位置信息，确定所述手指按压区域22与预设的指纹采集区域21的重叠区域20的位置信息。这里需要说明的是，图2所示为用户在该指纹采集区域21输入指纹时，存在该重叠区域20，在用户不想输入指纹时，终端检测到的手指按压区域与该指纹采集区域之间没有重叠区域，此时终端就不会控制指纹模组进行指纹采集，本流程结束。By way of example, FIG. 2 is a schematic diagram of each area on the terminal during fingerprint collection according to an exemplary embodiment. As shown in FIG. 2 , the preset
这里，若如图2所示，终端确定手指按压区域22与预设的指纹采集区域21之间存在重叠区域20，确定了该重叠区域20的位置信息后，终端可以根据所述重叠区域20的位置信息，确定该重叠区域20的形状和大小。Here, if as shown in FIG. 2 , if the terminal determines that there is an overlapping
这里，通常情况下指纹模组只需要采集一定大小和形状的指纹图像就可以进行准确的指纹识别，该第一区域可以是能够进行指纹识别的指纹图像所占据最小区域或者大于该最小区域，即该第一区域在大小上可以完全覆盖该最小区域。Here, under normal circumstances, the fingerprint module only needs to collect a fingerprint image of a certain size and shape to perform accurate fingerprint recognition. The first area may be sized to completely cover the minimum area.
示例的，假设该第一区域可以是15毫米*17毫米，终端确定的该重叠区域20为14毫米*17毫米时，可以确定该重叠区域在大小上不能覆盖该第一区域，终端确定的该重叠区域20为16毫米*17毫米时，可以确定该重叠区域在大小上覆盖该第一区域。示例的，该第一区域也可以是指纹采集区域。当用户手指完全覆盖该指纹采集区域时，该手指按压区域与指纹采集区域之间的重叠区域就是该指纹采集区域，此时，重叠区域与该第一区域在大小上完全相同，可以覆盖该第一区域。For example, assuming that the first area may be 15 mm*17 mm, and the overlapping
这里，终端确定该重叠区域20在大小上可以覆盖预设的第一区域时，表明采集该重叠区域20内的指纹图像就可以保证能够进行后续的指纹识别，此时终端就可以进行指纹采集，终端可以先确定点亮区域，该点亮区域在该重叠区域20内，且该点亮区域为可识别的指纹图像所占的区域，以保证采集该点亮区域内的指纹图像可以进行后续的指纹识别。这里，该点亮区域可以为全部的重叠区域20，也可以是重叠区域20中的部分区域，只要该区域内的指纹图像可以进行指纹识别即可。Here, when the terminal determines that the overlapping
这里，终端确定了点亮区域后，就可以打开指纹模组的光源点亮该点亮区域，在该点亮区域处形成亮斑，入射光照射至用户的指尖时，用户手指指纹的凹凸表面会把光线向着四面八方反射，虽然入射光线是互相平行的，由于各点的法线方向不一致，造成反射光向不同的方向无规则地反射，指纹模组接收到不同的反射光后，就可以确定出一个指纹图像，如此就采集到该点亮区域内的指纹图像。Here, after the terminal has determined the lighting area, the light source of the fingerprint module can be turned on to light the lighting area, and a bright spot is formed in the lighting area. The surface will reflect light in all directions, although the incident light is parallel to each other, due to the inconsistent normal direction of each point, the reflected light is randomly reflected in different directions. After the fingerprint module receives different reflected light, it can A fingerprint image is determined, and thus the fingerprint image in the illuminated area is collected.
这里需要说明的是，终端上的显示器可以是AMOLED(Active Matrix/OrganicLight Emitting Diode，主动矩阵有机发光显示器)，所述AMOLED具有反应速度较快、对比度更高、视角较广等特点，所述AMOLED中的每个像素都可以进行独立的开关，故终端可以控制AMOLED打开该点亮区域内的像素发射采集指纹图像所需要的亮眼白光，并关闭不需要的像素，这样就可以点亮该点亮区域，在该点亮区域形成高亮光斑，以便采集指纹图像。It should be noted here that the display on the terminal may be an AMOLED (Active Matrix/OrganicLight Emitting Diode, active matrix organic light-emitting display), and the AMOLED has the characteristics of fast response, higher contrast, and wider viewing angle. Each pixel can be switched independently, so the terminal can control the AMOLED to turn on the pixels in the lighted area to emit the bright white light needed to collect the fingerprint image, and turn off the unnecessary pixels, so that the point can be lit. Bright area, where a bright spot is formed in order to capture fingerprint images.
本实施例可以检测手指按压区域的位置信息；根据所述手指按压区域的位置信息，确定所述手指按压区域与预设的指纹采集区域的重叠区域的位置信息；在根据所述重叠区域的位置信息，确定所述重叠区域在大小上覆盖预设的第一区域时，确定点亮区域，所述点亮区域在所述重叠区域内，为可识别的指纹图像所占的区域；点亮所述点亮区域，获取所述点亮区域内的指纹图像，如此，终端在采集指纹时只会在该点亮区域内形成亮斑，而该点亮区域在用户手指按压区域中的重叠区域内，故形成的亮斑就会被用户手指完全覆盖，不会露出刺眼亮光。This embodiment can detect the position information of the finger pressing area; according to the position information of the finger pressing area, determine the position information of the overlapping area of the finger pressing area and the preset fingerprint collection area; When it is determined that the overlapping area covers the preset first area in size, the lighting area is determined, and the lighting area is within the overlapping area, which is the area occupied by the recognizable fingerprint image; In this way, the terminal will only form a bright spot in the lighted area when collecting fingerprints, and the lighted area is in the overlapping area of the user's finger pressing area. , so the formed bright spot will be completely covered by the user's finger, and no dazzling light will be exposed.
在一种可能的实施方式中，上述指纹采集方法中的步骤103可以实现为以下步骤A1。In a possible implementation manner,
在步骤A1中，在根据所述重叠区域的位置信息，确定所述重叠区域在大小上覆盖所述第一区域且不能覆盖预设的第二区域时，确定所述重叠区域为所述点亮区域。In step A1, when it is determined according to the position information of the overlapping area that the overlapping area covers the first area in size and cannot cover the preset second area, determine that the overlapping area is the lighting area.
这里，该第二区域在大小上可以完全覆盖该第一区域，并比该第一区域大，示例的，如该第一区域为15毫米*17毫米，该第二区域可以是17毫米*19毫米。在该重叠区域在大小上可以覆盖该第一区域但是不能覆盖第二区域时，表明该重叠区域内采集的指纹图像可以进行指纹识别但也不是太大，此时，为了加快指纹采集速度也保证采集到的指纹图像可以有效地进行指纹识别，可以直接将该重叠区域确定为该点亮区域，点亮该重叠区域进行指纹采集。Here, the second area may completely cover the first area and be larger than the first area. For example, if the first area is 15 mm*17 mm, the second area may be 17 mm*19 mm mm. When the overlapping area can cover the first area but cannot cover the second area, it indicates that the fingerprint image collected in the overlapping area can be used for fingerprint identification but is not too large. The collected fingerprint image can effectively perform fingerprint identification, and the overlapping area can be directly determined as the lighting area, and the overlapping area can be illuminated for fingerprint collection.
本实施例可以在根据所述重叠区域的位置信息，确定所述重叠区域在大小上覆盖所述第一区域且不能覆盖预设的第二区域时，直接确定该重叠区域为点亮区域，加快了指纹采集速度，也保证了指纹采集的有效性。In this embodiment, when it is determined according to the position information of the overlapping area that the overlapping area covers the first area in size and cannot cover the preset second area, the overlapping area can be directly determined to be a lighting area, thereby speeding up the process. The speed of fingerprint collection is improved, and the validity of fingerprint collection is also guaranteed.
在一种可能的实施方式中，上述指纹采集方法中的步骤103可以实现为以下步骤A2。In a possible implementation manner,
在步骤A2中，在根据所述重叠区域的位置信息，确定所述重叠区域在大小上覆盖预设的第三区域时，确定所述重叠区域中的部分区域为所述点亮区域，所述第三区域在大小上覆盖所述第一区域。In step A2, when it is determined according to the position information of the overlapping area that the overlapping area covers a preset third area in size, it is determined that a part of the overlapping area is the lighting area, and the The third area covers the first area in size.
这里，该第三区域在大小上可以完全覆盖该第一区域，该第三区域可以与第二区域相同，也可以比第二区域大，示例的，该第三区域可以是指纹采集区域；如该第一区域为15毫米*17毫米，该第三区域可以是18毫米*20毫米。在该重叠区域在大小上可以覆盖该第三区域时，表明该重叠区域内采集的指纹图像可以足够进行指纹识别并且还多出许多，此时，为了减小点亮的亮斑面积也为了采集到的指纹图像可以有效地进行指纹识别，可以从该重叠区域中选择可识别的指纹图像所占的区域为点亮区域。优选的，该点亮区域可以位于该重叠区域的中间位置处，可以防止点亮的亮斑的光线从手指下漏出。Here, the third area may completely cover the first area in size, the third area may be the same as the second area, or may be larger than the second area, for example, the third area may be a fingerprint collection area; such as The first area is 15mm*17mm, and the third area may be 18mm*20mm. When the overlapping area can cover the third area in size, it indicates that the fingerprint images collected in the overlapping area are sufficient for fingerprint identification and there are many more. The obtained fingerprint image can be effectively used for fingerprint identification, and the area occupied by the recognizable fingerprint image can be selected from the overlapping area as the lighting area. Preferably, the lighting area may be located in the middle of the overlapping area, which can prevent the light of the lighting spot from leaking from under the finger.
这里需要说明的是，该第一区域、第二区域和第三区域在大小上均可以被指纹采集区域完全覆盖。该第三区域也可以是指纹采集区域。It should be noted here that the size of the first area, the second area and the third area can be completely covered by the fingerprint collection area. The third area may also be a fingerprint collection area.
本实施例可以，在根据所述重叠区域的位置信息，确定所述重叠区域在大小上覆盖预设的第三区域时，确定所述重叠区域中的部分区域为所述点亮区域，即减小点亮的亮斑面积也保证采集到的指纹图像可以有效地进行指纹识别。In this embodiment, when it is determined that the overlapping area covers a preset third area in size according to the position information of the overlapping area, a part of the overlapping area is determined to be the lighting area, that is, the reduced area is the lighting area. The small illuminated bright spot area also ensures that the collected fingerprint image can be effectively used for fingerprint identification.
在一种可能的实施方式中，上述指纹采集方法还可以包括以下步骤B1。In a possible implementation manner, the above fingerprint collection method may further include the following step B1.
在步骤B1中，在所述重叠区域在大小上未覆盖所述第一区域时，输出提示信息，所述提示信息用于提示用户重新输入指纹。In step B1, when the overlapping area does not cover the first area in size, output prompt information, where the prompt information is used to prompt the user to re-input the fingerprint.
这里，终端在所述重叠区域在大小上未覆盖所述第一区域时，表明该重叠区域太小，终端采集该重叠区域内的指纹图像后，并不能识别出该指纹图像对应的用户，这就说明用户在输入指纹时，手指按压区域较多地偏离了指纹采集区域，此时，终端可以直接显示提示信息，提示用户在所述指纹采集区域重新输入指纹，避免终端根据采集的较小的指纹图像进行指纹识别失败。Here, when the overlapping area does not cover the first area in size, it indicates that the overlapping area is too small, and after collecting the fingerprint image in the overlapping area, the terminal cannot identify the user corresponding to the fingerprint image. It means that when the user inputs the fingerprint, the finger pressing area deviates more from the fingerprint collection area. At this time, the terminal can directly display the prompt information to prompt the user to re-enter the fingerprint in the fingerprint collection area, so as to avoid the terminal according to the collected smaller fingerprint. Fingerprint identification of the fingerprint image failed.
示例的，该提示信息可以上述的用于提示该指纹采集区域位置的提示图案，如可以是采用较小的亮度点亮该指纹采集区域，也可以是显示该指纹采集区域的边界线，也可以是显示一提示框，该提示框内显示提示信息“请重新输入指纹”；也可以是直接输出语音“请重新输入指纹”等等。Exemplarily, the prompt information may be the above-mentioned prompt pattern for prompting the location of the fingerprint collection area. For example, it may be to light the fingerprint collection area with a small brightness, or to display the boundary line of the fingerprint collection area, or it may be It is to display a prompt box, and the prompt message "Please re-enter your fingerprint" is displayed in the prompt box; it can also directly output the voice "Please re-enter your fingerprint" and so on.
这里，该提示信息吸引用户注意到后，用户可以在该指纹采集区域重新输入指纹，直至用户输入指纹的位置不再偏离，这样可以持续训练用户按压的准确性。最终提高指纹识别的成功概率。Here, after the prompt information attracts the user's attention, the user can re-input the fingerprint in the fingerprint collection area until the position of the user's input fingerprint is no longer deviated, so that the accuracy of the user's pressing can be continuously trained. Finally, the success probability of fingerprint identification is improved.
本实施例可以在所述重叠区域在大小上未覆盖所述第一区域时，输出提示信息，提示用户在所述指纹采集区域重新输入指纹，这样可以持续训练用户按压的准确性。最终提高指纹识别的成功概率。In this embodiment, when the overlapping area does not cover the first area in size, prompt information can be output to prompt the user to re-input a fingerprint in the fingerprint collection area, so that the accuracy of the user's pressing can be continuously trained. Finally, the success probability of fingerprint identification is improved.
在一种可能的实施方式中，上述指纹采集方法中的步骤B1还可以包括以下步骤B11，上述的指纹采集方法还可以包括以下步骤B2。In a possible implementation manner, step B1 in the above fingerprint collection method may further include the following step B11, and the above fingerprint collection method may further include the following step B2.

在步骤B2中，采集所述指纹采集区域中的部分或全部区域处的指纹图像。In step B2, fingerprint images at part or all of the fingerprint collection area are collected.
这里，终端也可以在用户指纹输入偏离时，点亮所述指纹采集区域中的部分区域或全部区域，在该指纹采集区域形成较大亮斑，该终端点亮的部分区域或全部区域未被该重叠区域覆盖，如此用户就能看到未被用户手指遮挡的亮斑，此时，用户就可以将手指移动至该亮斑处，遮挡该亮斑，同时，由于该指纹模组的入射光已射入亮斑处的手指，此时该指纹模组就不需要打开光源，可以直接获取该部分区域或全部区域内的手指指纹反射的反射光，得到该部分区域或全部区域内的指纹图像，提高指纹采集速率。Here, when the user's fingerprint input deviates, the terminal can also light up part or all of the fingerprint collection area, forming a large bright spot in the fingerprint collection area, and the terminal lit up part or all of the area is not covered by the fingerprint collection area. The overlapping area is covered, so that the user can see the bright spot that is not blocked by the user's finger. At this time, the user can move the finger to the bright spot to block the bright spot. At the same time, since the incident light of the fingerprint module has been The fingerprint module does not need to turn on the light source at this time, and can directly obtain the reflected light reflected by the fingerprint of the finger in the part or all of the area, and obtain the fingerprint image in the part or all of the area. Improve fingerprint collection rate.
