The following are detailed below.
The terms "first," "second," "third," and "fourth," etc. in the description and claims of this application and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Hereinafter, some terms in the present application are explained to facilitate understanding by those skilled in the art.
(1) A terminal device, also called a User Equipment (UE), is a device providing voice and/or data connectivity to a User, for example, a handheld device with an unlimited connection function, a vehicle-mounted device, and so on. Common terminals include, for example: the mobile phone includes a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), and a wearable device such as a smart watch, a smart bracelet, a pedometer, and the like.
(2) Parallel execution means that at least two actions are performed simultaneously on different processes, such as action a and action B, action a being performed on process 1, action B being performed on process 2, and action B being performed during the execution of action a.
Referring to fig. 1, fig. 1 is a schematic flow chart of a reminding method provided in an embodiment of the present application, and is applied to a terminal device including a facial image capturing device and a touch display screen, where the facial image capturing device may be a front camera of the terminal device or a common camera module, which is not limited herein, and the method includes:
step 101: and the terminal equipment acquires the facial image of the user through the facial image acquisition device.
In an example, when the terminal device detects that the pending event requires a face unlock, step 101 is performed.
Wherein, the event to be processed comprises: payment events, screen unlock events, video encrypted chat events, application login events, and the like. When the event to be processed is a screen unlocking event and the terminal device is in a black screen state before step 101, the terminal device needs to light a touch display screen of the terminal device before step 101.
Further, when the facial image of the user is collected, the brightness of the touch display screen is the same under different events to be processed. Or, when the facial image of the user is collected, the brightness of the touch display screen is determined according to the event to be processed, specifically: each event to be processed corresponds to a priority, the higher the priority is, the higher the brightness of the touch display screen is when the facial image of the user is collected, and the lower the priority is, the lower the brightness of the touch display screen is when the facial image of the user is collected. Or, when the facial image of the user is collected, the brightness of the touch display screen is determined according to the brightness of the ambient light, specifically: the higher the brightness of the ambient light is, the lower the brightness of the touch display screen is when the facial image of the user is collected, and the lower the brightness of the ambient light is, the higher the brightness of the touch display screen is when the facial image of the user is collected. Or, different time periods correspond to different brightness, and when the facial image of the user is collected, the brightness of the touch display screen is determined according to the time of the current system.
Step 102: when the number of facial features contained in the facial image of the user is smaller than a first threshold value, the terminal equipment starts a timer.
Wherein the first thresholds of different pending events are the same, such as 50, 55, 58, 60, etc. Alternatively, the first threshold is determined based on the pending event. The method specifically comprises the following steps: each event to be processed corresponds to a priority, the higher the priority is, the larger the first threshold is, and the lower the priority is, the smaller the first threshold is.
The priority corresponding to the event to be processed may be user-defined, or may be user-defined by the terminal device, which is not limited herein.
The timeout durations of the different pending event timers are the same, for example, all are 1 s. Alternatively, the timeout duration of different pending event timers may be different, such as 1s for a payment event and 50ms for a screen unlock event.
Step 103: the terminal equipment continues to collect the facial image of the user through the facial image collecting device, and determines the reason for causing the number of facial features contained in the facial image of the user to be smaller than the first threshold value.
Wherein the act of the terminal device continuing to capture the facial image of the user by the facial image capture device and the act of determining the cause for the number of facial features contained in the facial image of the user being less than the first threshold are performed in parallel. Therefore, the time of the whole method flow can be prolonged by executing the two actions in parallel, and the user experience is further improved.
In an embodiment, the specific implementation manner of the terminal device determining the reason why the number of facial features included in the facial image of the user is smaller than the first threshold value is as follows:
when the number of facial features contained in the facial image of the user is 0, the terminal device determines that the reason why the number of facial features contained in the facial image of the user is less than the first threshold value is that the face of the user is not within the acquisition range of the facial image acquisition device.
Specifically, if there is no facial feature in one image captured by the facial image capturing device, in this case, there is a possibility that the facial image capturing device does not capture any face image, that is, the face of the user is not within the capturing range of the facial image capturing device.
In an embodiment, the specific implementation manner of the terminal device determining the reason why the number of facial features included in the facial image of the user is smaller than the first threshold value is as follows:
when the number of facial features included in the facial image of the user is greater than 0 and the current ambient brightness is less than a second threshold, it is determined that the reason why the number of facial features included in the facial image of the user is less than the first threshold is insufficient brightness of the face illuminating the user.
Specifically, if the facial image capture device captures an image with facial features but not too much in a case where the current ambient brightness is not too bright, there is a possibility that the supplementary lighting for the face is insufficient, that is, the brightness of light illuminating the face of the user is insufficient.
In an embodiment, the specific implementation manner of the terminal device determining the reason why the number of facial features included in the facial image of the user is smaller than the first threshold value is as follows:
when the number of the facial features contained in the facial image of the user is larger than 0 and the brightness of the facial image of the user is larger than or equal to a second threshold value, determining that the reason that the number of the facial features contained in the facial image of the user is smaller than the first threshold value is that the face of the user is blocked by a blocking object.
Specifically, if the facial image capture device has facial features but not too many in an image captured under the condition that the current ambient brightness is still available, in this case, there is a possibility that something blocks the face, that is, a blocking object blocks the face of the user.
Step 104: when the timer is overtime and the number of the facial features contained in the facial image of the user collected by the facial image collecting device is still smaller than the first threshold value, the terminal equipment displays prompt information on the touch display screen, wherein the prompt information comprises the reason.
The specific implementation mode of the terminal device for displaying the prompt information on the touch display screen is as follows: and popping up a prompt box on the touch display screen, and displaying the prompt information in the prompt box.
Further, when the number of the facial features contained in the acquired facial image of the user is larger than or equal to a first threshold value, the terminal equipment matches the facial image of the user with a facial template; when the face image of the user matches the face template, a pending event is executed.
For example, assuming that the event to be processed is a screen unlocking event, the facial image acquisition device is a front-facing camera, the first threshold is 50, the timeout duration of the timer is 1s, the terminal device acquires an image through the front-facing camera, if the number of facial features contained in the image is 0 (less than 50), the terminal device starts the timer and then continues to acquire the image through the front-facing camera, in the process of continuing to acquire the image, the terminal equipment determines the reason why the acquired image contains less facial features, the reason is that the face of the user is not within the capturing range of the face image capturing apparatus, the time length counted by the timer exceeds 1s, and the number of the facial features contained in the acquired image is still not enough to be 50, the terminal device pops up a prompt box on the touch display screen, prompt information is displayed in the prompt box, and the prompt information can be 'the front camera is not aligned with the face', for example.
It is thus clear that in this application, if the facial image quality of gathering is unqualified just not carry out facial image matching operation, the consumption of reducible consumption, in addition, after the facial image quality of gathering for the first time is unqualified, start a timer, after the timer is overtime, facial image quality that facial image collection system gathered is still unqualified, the suggestion user causes the unqualified reason of facial image quality, so that the user carries out corresponding adjustment based on this reason, and then promotes the quality of the facial image of follow-up collection.
In an embodiment, after the prompt information is displayed on the touch display screen, the method further includes:
when the difference value between the number of facial features contained in a first facial image of the user and the number of facial features contained in a second facial image of the user is smaller than a third threshold value, the terminal device stops collecting the facial image of the user, wherein the first facial image is the facial image of the user collected before the prompt information is displayed, and the second facial image is the facial image of the user collected after the prompt information is displayed.
The third threshold is smaller than the first threshold, and the third threshold may be, for example, 10, 11, 14, 15, 20, or other values.
Specifically, if the number of facial features included in the first facial image is 0 and the number of facial features included in the second facial image is 0, this indicates that the quality of the facial image of the user captured by the facial capture device is still not improved after the reason for prompting the user that the number of facial features included in the facial image is small is displayed, and in this case, there is a possibility that the face unlock function is started due to a user misoperation, and therefore, in order to reduce the power consumption of the terminal device, in this case, the operation of capturing the facial image of the user is directly stopped, that is, the face unlock function is directly stopped.
In an embodiment, after the prompt information is displayed on the touch display screen, the method further includes:
when the difference value between the number of facial features contained in a first facial image of the user and the number of facial features contained in a second facial image of the user is smaller than a third threshold value, the terminal device prompts the reason through voice, wherein the first facial image is the facial image of the user collected before the prompt information is displayed, and the second facial image is the facial image of the user collected after the prompt information is displayed;
when the difference value between the number of facial features contained in the third facial image of the user and the number of facial features contained in the second facial image of the user is smaller than the third threshold value, the terminal equipment stops collecting the facial image of the user, and the third facial image is the facial image of the user collected after the reason is prompted by voice.
Specifically, assuming that the number of facial features included in the first facial image is 0 and the number of facial features included in the second facial image is also 0, this indicates that the quality of the facial image of the user captured by the facial capture device is still not improved after the case where the reason for prompting the user that the number of facial features included in the facial image is small is displayed. This case is likely because the display prompt user does not see the prompt information, and in this case, the user is prompted again by a voice prompt (a prompt different from the display prompt) for the reason that the number of facial features included in the facial image is small. If the user is prompted again, if the number of the facial features included in the acquired third facial image is 0, it may be determined that the face unlocking function is started due to the user misoperation, and therefore, in order to reduce the power consumption of the terminal device, in this case, the operation of acquiring the facial image of the user is directly stopped, that is, the face unlocking function is directly stopped.
In an embodiment, the method further comprises:
when the number of facial features contained in the N facial images of the user collected by the facial image collecting device is smaller than the first threshold value, the terminal equipment stops collecting the facial images of the user, N is an integer larger than 2, and the timeout duration of the timer is smaller than the duration required for collecting the N facial images.
Wherein the values of different pending events N are the same, for example, N is all equal to 5. Alternatively, the values of different pending events N are different, such as 5 for the payment event N and 3 for the screen unlock event N.
Therefore, the terminal equipment limits the maximum number of times of mistakenly acquiring the facial image, and the power consumption of the terminal equipment can be further reduced.
The embodiment of the present application further provides another more detailed method flow, as shown in fig. 3, including:
step 301: the terminal device detects a pending event.
Step 302: and the terminal equipment acquires the facial image of the user through the facial image acquisition device.
Step 303: the terminal device judges whether the number of facial features contained in the facial image of the user is smaller than a first threshold value.
If so, go to step 304.
If not, go to step 312.
Step 304: the terminal device starts a timer.
Step 305: and the terminal equipment continues to acquire the facial image of the user through the facial image acquisition device within the timing duration.
Step 306: and in the process that the terminal equipment continues to collect the facial image of the user through the facial image collecting device within the timing duration, the terminal equipment determines the reason for causing the number of the facial features contained in the facial image of the user to be smaller than the first threshold value.
When the number of facial features included in the facial image of the user is 0, it is determined that the reason why the number of facial features included in the facial image of the user is less than the first threshold is that the face of the user is not within the capturing range of the facial image capturing apparatus.
When the number of facial features included in the facial image of the user is greater than 0 and the current ambient brightness is less than a second threshold, it is determined that the reason why the number of facial features included in the facial image of the user is less than the first threshold is insufficient brightness of the face illuminating the user.
Step 307: and the terminal equipment judges whether the number of the facial features contained in the facial image of the user acquired by the facial image acquisition device in the timing duration is smaller than the first threshold value or not.
If yes, go to step 308.
If not, go to step 312.
Step 308: and the terminal equipment displays prompt information on the touch display screen, wherein the prompt information comprises the reason.
Step 309: the terminal device determines whether a difference between the number of facial features included in a first facial image of the user, which is an image of the user's face acquired before the prompt information is displayed, and the number of facial features included in a second facial image of the user, which is an image of the user's face acquired after the prompt information is displayed, is smaller than a third threshold.
If yes, go to step 311.
If not, go to step 303.
Step 310: the terminal equipment judges whether the number of facial features contained in the N facial images of the user collected by the facial image collecting device is smaller than the first threshold value, N is an integer larger than 2, and the overtime length of the timer is smaller than the time length required for collecting the N facial images.
If yes, go to step 311.
If not, go to step 312.
Step 311: and the terminal equipment stops acquiring the facial image of the user.
Step 312: and the terminal equipment matches the face image of the user with the face template.
Step 313: and the terminal equipment judges whether the face image of the user is matched with the face template or not.
If yes, go to step 314.
If not, no operation is carried out.
Step 314: and the terminal equipment executes the event to be processed.
It should be noted that, the specific implementation of the steps of the method shown in fig. 3 can refer to the specific implementation described in the above method, and will not be described here.
