1. Technical Field
The present disclosure relates to communication terminals, and more particularly to a communication terminal for conveniently answering an incoming call.
2. Description of Related Art
Making a phone call is a basic functionality of mobile phones. Generally, mobile phones provide one or more modes for answering incoming calls from others, such as by pressing keys, and by performing function modules. However, most incoming calls can only be answered by actuating a button/key.
Therefore, what is needed is a communication terminal for conveniently answering incoming call.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

The alerting unit 10 is configured for generating an alert signal when the communication terminal 100 has an incoming call. The alert signal can be audio or physical such as a beep or the terminal will vibrate. In the embodiment, the alerting unit 10 is a speaker.
The capturing unit 12 is configured for capturing consecutive images according to the alert signal from the alerting unit 10. The phone receiver unit 13 is configured for listening to voice of the caller when the incoming call is answered. In the embodiment, the capturing unit 12 and the phone receiver unit 13 are positioned on a same side of the communication terminal 100 (shown in
The detecting unit 11 is configured for detecting whether the incoming call is answered manually, such as the user pressing a key. If the detecting unit 11 detects that the incoming call is not being answered manually, the capturing unit 12 captures consecutive images. In other embodiments, the detecting unit 11 can be configured for detecting whether the incoming call was disconnected by the caller or the callee.
The identifying unit 16 is configured for identifying the consecutive captured images of the capturing unit 12 and determining whether the last captured image shows an image of an ear. If the last captured image does not show an image of an ear, the capturing unit 12 continues capturing consecutive images. In other embodiments, the detecting unit 11 is enabled again if it is determined that the last captured image is not showing an image of an ear.
If the last captured image shows an image of an ear, the condition monitoring unit 18 is configured for determining whether the image of the ear in the last captured image is substantially in the centre of the identified image. If the ear image is substantially in the centre of the identified image, this means that the user is holding the phone against his ear and the phone answering unit 14 is configured for answering the incoming call. If the image of the ear in the last captured image is substantially in the centre of the identified image, the capturing unit 12 continues capturing. In other embodiments, if the image of the ear in the last captured image is substantially in the centre of the identified image, the detecting unit 11 is enabled again.
As described above, in other embodiments, the condition monitoring unit 18 can be omitted. If the identifying unit 16 determines that the last captured image shows an image of an ear, the phone answering unit 14 answers the incoming call. The detecting unit 11 also can be omitted. If the alerting unit 10 alerts an incoming call, the capturing unit 12 captures consecutive images. The communication terminal 100 can conveniently answer an incoming call without any manual input.

Beginning in step S300, generating an alert signal when the communication terminal has an incoming call. The alert function is enabled by the alerting unit 10.
In step S301, detecting whether the incoming call is answered. If the incoming call is not answered, step S302 is implemented.
In step S302, capturing consecutive images according to the alert signal. The capturing function is enabled by the capturing unit 12 when the alerting unit 10 generates the alert signal.
In step S304, identifying the captured consecutive images and determining whether the last captured image shows an image of an ear. If the last captured image shows the image of the ear, step S306 is implemented. If the last captured image does not show the image of the ear, step S302 is implemented again. In other embodiments, if the last captured image does not show the image of the ear, step S301 is implemented again.
In step S306, determining whether the image of the ear in the last captured image is substantially in the centre of the identified image. If the image of the ear in the last captured image is substantially in the centre of the identified image, step S310 is implemented. If the image of the ear in the last captured image is not substantially in the centre of the identified image, step S302 is implemented again. In other embodiments, if the image of the ear in the last captured image is not substantially in the centre of the identified image, step S301 is implemented again.
In step S310, answering the incoming call.
In step S312, turning off the capturing function when the incoming call is answered.

The processor 24 is operatively coupled to the camera module 22 and the memory 26. A noncontact ear answering application 28 is stored in the memory 26 and is configured for execution by the processor 24. The noncontact ear-answering application 28 includes the following instructions: first, monitor by the processor 24 in real time whether an incoming call is received from another communication terminal; second, initiate the camera module 22 to capture consecutive images by the processor 24 that the incoming call is being received from the another communication terminal; third, analyze the consecutive captured images by the processor 24 to identify whether the last captured image shows an image of an ear according to a predetermined recognition algorithm; fourth, answer the incoming call by the processor 24 upon an analyzing result that the last captured image shows an image of an ear, so as to allow a communication to be performed between the communication terminal 200 and the another communication terminal; fifth, disable the camera module 22 when the incoming call from the another terminal is determined by the processor 24 being answered by the communication terminal 200.
The communication terminal 200 is similar to the communication 100 as described above.
It is to be understood, however, that even though numerous characteristics and advantages have been described with reference to particular embodiments, the present invention is not limited to the particular embodiments described and exemplified, and the embodiments are capable of considerable variation and modification without departure from the scope and spirit of the appended claims.
