The present disclosure relates to the technical field of mobile terminals, and more particularly, to a mobile terminal and a method for the mobile terminal to automatically answer an incoming call.
BACKGROUND OF THE DISCLOSURE
With rapid development of smart terminals, mobile terminals such as mobile phones and tablet computers become more and more powerful in terms of functions and the display screens thereof become increasingly larger. This makes it more and more difficult to operate a mobile terminal with a single hand, and most of the mobile terminals need to be operated with both hands. Especially when there is an incoming call for a large-screen mobile terminal, it is not easy to press a button or slide the screen with a single hand to answer the incoming call, and instead, usually this must be done with both hands. If the user happens to be in a busy state (e.g., one hand becomes dirty, an article is being held in one hand, or the user is driving a vehicle) at this moment, it will be very inconvenient to manually answer the incoming call and, also, there is a risk that the mobile terminal might be dropped inadvertently to become damaged.

DETAILED DESCRIPTION OF THE DISCLOSURE
To make the technical problems to be solved, the technical solutions and the benefits of the present disclosure clearer and more apparent, the present disclosure will be further detailed hereinbelow with reference to the attached drawings and embodiments thereof. It shall be understood that, the specific embodiments described herein are only used to explain but not to limit the present disclosure.
Referring to FIG. 1, there is shown a schematic flowchart of a first embodiment of a method for automatically answering an incoming call according to the present disclosure. As shown in FIG. 1, the method may comprises the following blocks:
Block 101: detecting if an auricle image is acquired at the screen side of the mobile terminal when there is an incoming call for the mobile terminal;
Block 102: if the auricle image is acquired, then comparing the auricle image with image templates in a pre-stored auricle standard library to determine whether there is a matching image template;
Block 103: if it is determined that there is a matching image template, then controlling the mobile terminal to answer the incoming call.
The mobile terminal may be selected from but is not limited to a mobile phone, a tablet computer, a palmtop or the like device that can be conveniently carried about.
It has been proved by the present inventor through a large number of scientific experiments that the auricles (or ears) have the uniqueness, and even for the twins, the auricles thereof are just similar but not identical to each other. And as time goes on, the auricle is not prone to deformation due to influences of the age and facial expressions or the like. Accordingly, the auricle can be used as a biological feature to identify users just like the fingerprint and the pupil, and nowadays mobile terminals are all equipped with an image capturing device such as a camera, so it is easy to capture the auricle image.
Referring to FIG. 2, there is shown a schematic flowchart of detecting if an auricle image is acquired at the screen side of the mobile terminal when there is an incoming call for the mobile terminal in FIG. 1. As shown in FIG. 2 and in combination with FIG. 1, the block 101 may comprises:
Block 201: monitoring if there is any incoming call for the mobile terminal;
Block 202: detecting if action information of a user satisfies a preset triggering condition when there is an incoming call for the mobile terminal;
Block 203: if the preset triggering condition is satisfied, then controlling the mobile terminal to acquire an image at the screen side and determining whether the image acquired is an auricle image.
In one embodiment, the preset triggering condition in the block 202 may be optionally an object that is approaching. In a specific embodiment for example, if an incoming call for the mobile terminal is monitored, a capacitive touch screen or a distance sensor may be further used to detect if there is any object approaching in block 202; and if there is an object approaching, the capacitive touch screen or a camera is used to acquire an image of the object at the screen side and determine whether the image of the object is an auricle image in the block 203.
In one embodiment, the capacitive touch screen of the mobile terminal can achieve determination of whether there is any body approaching according to the electrical signal of the human body so as to determine the images of different body parts such as the face, the auricle or other parts.
Further, the preset triggering condition in the block 202 may be optionally to press or touch a button or icon for activating the auricle identification by the user, and optionally, the specific action information of the user may be, for example, pressing the capacitive touch screen continuously, performing a specific gesture action, labeling a special pattern on the capacitive touch screen, or language information from user, but it is not limited thereto.
The method further comprises the following blocks before the block 102 or the block 101: acquiring image templates and storing the image templates to the auricle standard library.
It can be understood that, the auricle image of the user may be acquired by using the capacitive touch screen or the camera of the mobile terminal, or the auricle image may be subjected to feature extraction for use as the image template and may be stored into the auricle standard library. In the present disclosure, the auricle image may be a colored or monochromatic image obtained by using the camera to take a photo of the auricle and may also be a capacitance distribution map obtained by using the capacitive touch screen to detect the capacitance of the auricle.
Referring further to Table 1, Table 1 is a table illustrating associations between image templates and users in the auricle standard library. As shown in Table 1, the auricles of different users may be associated with the different users and may be stored into the auricle standard library.

other users










Optionally, a super-user may be further provided in this method, who may perform operations such as making additions, editions, amendments, deletions on the image templates or associated users in the auricle standard library through authentication.
Referring to Table 2, Table 2 is an exemplary table illustrating authentication of the super-user. As shown in Table 2, the super-user may choose to use the password authentication mode or other biological authentication modes.

For acquiring the password of the



super-user or other preset passwords for

Other biological feature
For acquiring a feature like a fingerprint,

super-user for verification









It can be understood that, if the super-user is authenticated by using a password or other biological features, then when the password acquired matches the password of the super-user or some other preset password or when the biological feature acquired matches the fingerprint, face, voice, or pupil of the super-user, it is considered that the super-user passes the verification. Then the mobile terminal determines that the current user is the super-user who can perform operations such as making additions, editions, amendments, deletion on the image templates or associated users thereof.
Optionally, when the mobile terminal activates the automatic answering function for the first time, i.e., when the block 101 or the block 203 is executed for the first time, this method provides operations of setting the number of automatically answered users, setting the auricle image templates and setting the authentication modes of the super-user. It can be understood that, the super-user will perform operations such as amendment through authentication later.
Optionally, the method may further comprise following blocks after the block 103:
Block 104: if it is determined that there is no matching image template, then displaying a prompt message of whether adopting other verification modes for answering;
Block 105: if what is acquired is an instruction, then further acquiring other verification modes and determining whether they satisfy a preset verification condition; and
Block 106: if the preset verification condition is satisfied, then controlling the mobile terminal to answer the incoming call.
If it is determined that there is no matching image template in the block 104, usually the mobile terminal is taken up and hold near the auricle and, therefore, the text prompt message may not be noticed in time. In this case, a sound or vibration may be used to prompt the user. That is, the block 104 may comprise: if it is determined that there is no matching image template, a message of whether adopting other verification modes to answer the incoming call will be displayed after prompting the user through a sound or vibration.
In the block 105, said other verification modes may optionally be password verification or other biological feature verification modes, which are same as the authentication modes of the super-user in Table 2. That is, optionally, the password is acquired and it is determined whether the password matches (or is the same as) the password of the pre-user or other preset password, or a feature such as a fingerprint, a face, a voice, or a pupil is acquired and it is determined whether the feature matches (or is the same as) the biological feature of the super-user. If it is determined that there is a matching password or feature, then the mobile terminal is controlled to answer the incoming call in the block 106.
Referring to FIG. 3, FIG. 3 is a schematic flowchart of a second embodiment of the method for automatically answering an incoming call according to the present disclosure. As shown in FIG. 3, the method may comprise:
Block 301: detecting if an auricle image is acquired at the screen side of the mobile terminal when there is an incoming call for the mobile terminal;
Block 302: if the auricle image is acquired, comparing the auricle image with the image templates in a pre-stored auricle standard library to determine whether there is a matching image template;
Block 303: if it is determined that there is a matching image template, then further determining whether a time at which the auricle image is acquired is within a preset usable time period; and
Block 304: if it is determined that the time at which the auricle image is acquired is within the preset usable time period, then controlling the mobile terminal to answer the incoming call.
In one embodiment, the block 301 and block 302 are the same as the block 101 and block 102 in the aforesaid first embodiment, so they will not be further described herein.
In one embodiment, the usable time period is associated with the image templates and preset in the auricle standard library or the module storing the auricle standard library.
The super-user according to the aforesaid first embodiment may further set the image template and the corresponding usable time period for different users through authentication so as to manage the time of answering the call for the different users.
Further, the super-user may sort a plurality of users into groups and set the usable time period of automatically answering an incoming call for each of the different groups. Referring to Table 3, Table 3 is an exemplary table illustrating associations between groups and usable time periods in the auricle standard library.
