In some embodiments, the trigger signal is triggered when the camera 201 of the smart terminal 20 acquires an operation image and recognizes a preset operation gesture from the operation image. At this time, the camera 201 is also used for acquiring a gesture image in front of the screen of the intelligent terminal 20. The camera 201 may only collect gesture images within a preset range from the screen of the intelligent terminal 20. And when the acquired gesture image is matched with the preset gesture image, the fact that a preset trigger signal is received is indicated.

For example, pressure sensors are disposed on the left side and the right side of the smart terminal 20, and the trigger information is generated when a change in pressure on the left side and/or the right side is detected. When the intelligent terminal screen is taken as a front view, the surface represented by the left view represents the left side surface, and the surface represented by the right view represents the right side surface.
The proximity sensor 206 is configured to detect whether an object is near the intelligent terminal 20, and generate the trigger signal when detecting that an object is near the intelligent terminal 20. In addition, although only one proximity sensor 206 is shown in fig. 2, it is understood that two or more proximity sensors may be disposed on the smart terminal 20, and a plurality of proximity sensors may be disposed at a plurality of positions, so that the signal for detecting the approach of the object may be more accurate and reliable.

The intelligent terminal 20 can execute the method provided by the embodiment of the invention, and has the corresponding functional modules and beneficial effects of the execution method. For technical details that are not described in detail in this embodiment, reference may be made to the method provided by the embodiment of the present invention. The smart terminal 20 may exist in a variety of forms, including but not limited to:
(1) a mobile communication device: such devices are characterized by mobile communications capabilities and are primarily targeted at providing voice, data communications. Such terminals include: smart phones, multimedia phones, functional phones, and low-end phones, etc.
(2) Ultra mobile personal computer device: the equipment belongs to the category of personal computers, has calculation and processing functions and generally has the characteristic of mobile internet access. Such terminals include: PDA, MID, and UMPC devices, etc.
(3) And other electronic equipment with data interaction function.
The embodiment of the invention provides an intelligent terminal, which is characterized in that whether a face exists in front of a screen of the intelligent terminal or not is detected, whether the intelligent terminal receives a preset trigger signal or not is detected, and when the face exists in front of the intelligent terminal and the preset trigger signal is received, a fingerprint identification function of the intelligent terminal is started. This embodiment has carried out certain restriction to cold-start fingerprint identification function, has reduced the emergence probability of maloperation, and in addition, fingerprint identification function need not be in the starting condition all the time, has reduced intelligent terminal's consumption.
Based on the intelligent terminal, the embodiment of the invention provides a method for starting fingerprint identification. Referring to fig. 3, fig. 3 is a flowchart illustrating a method for initiating fingerprint identification according to an embodiment of the present invention. As shown in fig. 3, the method includes:
step 31, detecting whether a human face exists in front of a screen of the intelligent terminal and detecting whether a preset trigger signal is received;
and step 33, when a human face exists in front of the screen of the intelligent terminal and a preset trigger signal is received, starting a fingerprint identification function of the intelligent terminal.
In the embodiment of the invention, whether a human face exists in a preset range from the screen of the intelligent terminal can be detected. The process of detecting the face can be that the image in front of the screen of the intelligent terminal is collected through the camera, then the image is subjected to feature extraction through a specific algorithm, the extracted features are matched with the known face characteristic vector, and whether the collected image is the face image or not is judged according to the matching result. The features of the image may be extracted by an Active Shape Model (ASM), a Local Binary Patterns (LBP) algorithm, a Principal Component Analysis (PCA), a Linear Discriminant Analysis (LDA) algorithm, and the like.
The triggering signal comprises a pressure signal, and the pressure signal is specifically triggered when a pressure sensor of the intelligent terminal detects pressure change, wherein the pressure sensor is located on the side face of the intelligent terminal. This side includes intelligent terminal's left surface, right flank, goes up side and downside. When the intelligent terminal screen is taken as a front view, a face represented by a left view represents the left side face, a face represented by a right view represents the right side face, a face represented by a top view represents the upper side face, and a face represented by a bottom view represents the lower side face.
It is understood that the pressure signal may be generated when a human hand acts on the smart terminal. Therefore, here, when it is detected that there is a human face in front of the screen of the smart terminal and it is detected that the human hand holds the smart terminal, that is, it is default that the human has an intention to use the smart terminal, at this time, the fingerprint recognition function of the smart terminal is started so that the human can light the screen and unlock at the same time.
It should be noted that, the above definition is that the trigger signal is generated when the pressure acting on the intelligent terminal changes, and in some embodiments, the trigger signal may be generated when the pressure value acting on the intelligent terminal is within a preset pressure value range. This can further reduce the probability of a false touch.
The trigger signal may be triggered when the proximity sensor of the smart terminal detects that an object is approaching. It is understood that the object near the smart terminal may be a human hand. Therefore, here, when it is detected that there is a human face in front of the screen of the smart terminal and it is detected that a human hand is close to the smart terminal, that is, it is default that there is an intention of using the smart terminal for a human, at this time, the fingerprint recognition function of the smart terminal is started so that the human can light the screen and unlock at the same time. It should be noted that the approaching object may be other approaching objects besides the human hand, such as a touch pen.
Further, when it is detected that the approaching object is a human hand, whether the trigger signal is triggered or not can be judged according to the gesture. Therefore, the trigger signal may be triggered when the camera of the smart terminal acquires an operation image and recognizes a preset operation gesture from the operation image. Here, when it is detected that there is a human face in front of the screen of the smart terminal and a preset operation gesture is detected, that is, it is default that there is an intention of using the smart terminal for a human, at this time, a fingerprint recognition function of the smart terminal is started so that the human can light the screen and unlock at the same time.
The preset operation gesture may be preset according to a preference of a person, for example, an "OK" gesture. When the fact that the user is matched with the preset gesture is detected, a trigger signal is generated.
The embodiment of the invention provides a method for starting fingerprint identification, which determines whether to start a fingerprint identification function of an intelligent terminal by detecting whether a face is in front of a screen of the intelligent terminal and according to the pressure change condition acting on the intelligent terminal, whether an approaching object exists or whether a preset operation gesture is met. This embodiment can reduce the emergence probability of maloperation, and in addition, fingerprint identification function need not be in the starting state all the time, has reduced intelligent terminal's consumption.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for initiating fingerprint identification according to another embodiment of the present invention. Fig. 4 differs from fig. 3 mainly in that after the detecting whether a preset trigger signal is received, the method further includes:
and 32, detecting whether the screen of the intelligent terminal faces downwards horizontally.
At this time, step 33 specifically includes, when a human face exists in front of the screen of the intelligent terminal, a preset trigger signal is received, and the screen of the intelligent terminal is not horizontally facing downward, starting a fingerprint recognition function of the intelligent terminal.
It can be understood that the screen orientation of the intelligent terminal can reflect whether the intelligent terminal user has the intention of using the intelligent terminal to a certain extent. For example, when a user sits to use the intelligent terminal, the screen of the intelligent terminal is generally upward, and when the user lies to use the intelligent terminal, the screen of the intelligent terminal is generally downward. Therefore, in the embodiment, whether the fingerprint identification function of the intelligent terminal is started is further judged according to the screen orientation of the intelligent terminal.
In this embodiment, when the screen of the intelligent terminal is facing down horizontally, i.e. the intelligent terminal is turned back on the horizontal plane, the default user does not need to use the intelligent terminal. Therefore, when the screen of the intelligent terminal faces upwards or faces downwards at other angles, the user is considered to have the use intention.
Therefore, in the embodiment, when the screen of the intelligent terminal is not horizontally downward, and a human face is detected in front of the screen of the intelligent terminal, and a preset trigger signal is received, the fingerprint recognition function of the intelligent terminal is started.
Wherein, as shown in fig. 5, detecting whether the screen of the intelligent terminal faces downwards horizontally includes:
321, detecting components of the gravity acceleration in three axial directions of a triaxial gravity sensor of the intelligent terminal in real time through the triaxial gravity sensor;
and 322, judging whether the screen of the intelligent terminal faces downwards or not according to the size and the positive and negative of the component.
In this embodiment, the screen orientation of the intelligent terminal is determined by the three-axis gravity sensor. The following describes an example of the determination process of the screen orientation of the smart terminal.
For example, as shown in fig. 6, the intelligent terminal is a mobile phone, the x-axis direction represents from left to right along the horizontal direction of the screen, if the mobile phone is not square, the shorter side is placed horizontally, and the longer side is placed vertically; the y-axis direction represents that the screen is directed to the top of the screen from the lower left corner of the screen along the vertical direction of the screen; the z-axis direction represents a direction pointing to the sky when the handset is horizontally positioned. In this embodiment, the three-axis gravity sensor is installed at a specific position of the mobile phone, and three axes of the three-axis gravity sensor are respectively overlapped or parallel to the x-axis direction, the y-axis direction, and the z-axis direction, so that the current tilt direction of the mobile phone can be calculated according to components of the gravity acceleration measured by the three-axis gravity sensor in the x-axis direction, the y-axis direction, and the z-axis direction, thereby determining the orientation of the mobile phone screen. For example, when the mobile phone is vertically placed as shown in fig. 6, the three-axis gravity sensor measures that the component of the gravitational acceleration on three coordinate axes of an xyz coordinate system is (0, -g, 0), wherein the component in the x-axis direction is 0, the component in the y-axis direction is-g, the magnitude of the component is the same as that of the gravitational acceleration, the direction of the component is opposite, the value of g takes a corresponding value according to the geographical position of the mobile phone, and the component in the z-axis direction is 0.
The embodiment of the invention provides a method for starting fingerprint identification, which determines whether to start a fingerprint identification function of an intelligent terminal by detecting whether a face is in front of a screen of the intelligent terminal, judging whether an approaching object exists or not according to the pressure change condition acting on the intelligent terminal or whether a preset operation gesture is met, and judging whether the screen of the intelligent terminal is horizontal downwards. This embodiment can reduce the emergence probability of maloperation, and in addition, fingerprint identification function need not be in the starting state all the time, has reduced intelligent terminal's consumption.
Referring to fig. 7, fig. 7 is a schematic structural diagram of an apparatus for initiating fingerprint identification according to an embodiment of the present invention. As shown in fig. 7, the apparatus 40 includes: a first detection module 401 and an activation module 402.
The first detection module 401 is configured to detect whether a human face exists in front of a screen of the intelligent terminal and detect whether a preset trigger signal is received; a starting module 402, configured to start a fingerprint identification function of the intelligent terminal when a human face exists in front of a screen of the intelligent terminal and a preset trigger signal is received.
The first detection module 401 sends a detection result to the starting module 402, and the starting module 402 determines whether to start the fingerprint identification function of the intelligent terminal according to the detection result.
The trigger signal may be triggered when a pressure sensor of the intelligent terminal detects a pressure change, wherein the pressure sensor is located on a side surface of the intelligent terminal.
The trigger signal may be triggered when a proximity sensor of the smart terminal detects that an object approaches, or triggered when an operation image is acquired by a camera of the smart terminal and a preset operation gesture is recognized from the operation image.
