Embodiment 1

[0039] figure 1 It is a flow chart of an embodiment of a method for improving lip recognition rate provided by the present invention.

[0040] Such as figure 1 As shown, the method for improving the lip recognition rate provided by this embodiment is applied to a mobile terminal, and is used to recognize the user's lip movement when the user communicates with other communication terminals through the mobile terminal. Of course, the mobile The terminal is provided with a display screen. The method for improving the lip language recognition rate specifically includes the following steps:

[0041] S101: Obtain the light intensity of the current ambient light.

[0042] When the mobile terminal recognizes the user's lip movement, the light sensor is activated to detect the light intensity of the current ambient light.

[0043] S102: When the light intensity is lower than a preset light intensity threshold, increase the brightness of the display screen.

[0044] After obtaining...

Embodiment 2

[0055] figure 2 It is a flow chart of another embodiment of the method for improving the lip recognition rate provided by the present invention.

[0056] like figure 2 As shown, the method for improving the lip recognition rate provided by this embodiment is applied to the mobile terminal, specifically, the lip recognition rate is improved when the mobile terminal communicates with other communication terminals, and the specific steps are:

[0057] S201: Determine whether the current condition satisfies a preset start condition.

[0058] When the user communicates with other communication terminals through the mobile terminal, it is judged whether the current condition satisfies the preset activation condition, and the next step is executed when the activation condition is met, otherwise, the judgment is continued.

[0059] In view of the powerful functions of current mobile terminals, the above-mentioned call can be a call with another mobile terminal, or communicate with...

Embodiment 3

[0078] image 3 It is a flow chart of another embodiment of the method for improving the lip recognition rate provided by the present invention.

[0079] like image 3 As shown, the method for improving the lip recognition rate provided by this embodiment is applied to the mobile terminal, specifically, the lip recognition rate is improved when the mobile terminal communicates with other communication terminals, and the specific steps are:

[0080] S301: Determine whether the current condition satisfies a preset start condition.

[0081] When the user communicates with other communication terminals through the mobile terminal, it is judged whether the current condition satisfies the preset activation condition, and the next step is executed when the activation condition is met, otherwise, the judgment is continued.

[0082] In view of the powerful functions of current mobile terminals, the above-mentioned call can be a call with another mobile terminal, or communicate with o...

Abstract

The embodiment of the invention provides a method for enhancing the lip language recognition rate and a mobile terminal. The method is applied to the mobile terminal. The method concretely comprises the steps that light intensity of current ambient light is acquired; then the light intensity is compared with a preset light intensity threshold, and brightness of a display screen is enhanced when the light intensity is less than the light intensity threshold so as to increase lighting for the lips; the lip image of a user is acquired through the front camera of the mobile terminal; and finally the acquired lip image is recognized so that information matched with the lip image is obtained. According to the method, lighting for the lips can be increased when the light intensity of the current ambient light is less than the light intensity threshold, i.e. the ambient light is insufficient so that the lip image acquired by the mobile terminal is enabled to be clearer, and the problem of the low lip language recognition rate under the condition of insufficient ambient light can be solved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for improving the recognition rate of lip language and a mobile terminal. Background technique [0002] During an actual call with a mobile terminal such as a mobile phone or a tablet computer with a call function, sometimes it is difficult for a second communication terminal communicating with the second communication terminal to hear the call content clearly due to local noise or other reasons. This situation may be that the sound received locally is too noisy, so that part or all of the voice sent locally is submerged in the noise, and the user of the second communication terminal cannot hear clearly; it may also be that the local user is inconvenient to speak loudly, resulting in The voice input by the user is too low, resulting in poor call quality of the second communication terminal, thereby affecting the call experience of the user. [0003] At pres...
