Embodiment 1

[0039] This embodiment provides an automatic keyboard unlocking device, which can be set in a mobile phone. figure 1 A structural block diagram of the device capable of automatically unlocking the keyboard is shown. The device may include: a state detection unit 100 , a camera 120 , a face detection unit 140 and an unlocking unit 160 .

[0040] Wherein, the state detection unit 100 is used to detect the pressure received on two or more predetermined positions on the surface of the mobile phone, and identify the mobile phone according to the pressure received on the two or more predetermined positions. Whether it is in a held state, when it is recognized that the mobile phone is in a held state, a trigger signal is generated and sent to the camera 120 . Usually, when the mobile phone user uses the mobile phone, the mobile phone will be held in the hand, and at this time, pressure will be generated on at least part of the surrounding side walls of the mobile phone. For example...

Embodiment 2

[0049] Embodiment 2 further provides an automatic keyboard unlocking device, which has a state detection unit different from that in Embodiment 1.

[0050] The state detection unit in Embodiment 1 is used to detect the pressure received on two or more predetermined positions on the surface of the mobile phone, and identify the pressure according to the detected pressure on the two or more predetermined positions Whether the mobile phone is in the hand-held state, and trigger the camera of the mobile phone when it is recognized that the mobile phone is in the hand-held state. The state detection unit in this embodiment 2 is used to detect the acceleration and the corresponding speed of the mobile phone, and when the detected speed is within a predetermined speed range, it will identify that the mobile phone is in a state of being held, thereby triggering the movement of the mobile phone. phone camera.

[0051] Figure 4 Shown is the structural block diagram of the keyboard au...

Embodiment 3

[0056] This embodiment further provides an automatic keyboard unlocking device.

[0057] When using the keyboard automatic unlocking device of embodiment 1 and embodiment 2, there may be such problems: when the mobile phone is placed in positions such as pockets and handbags, two or more predetermined positions of the mobile phone (such as The left and right sides or the upper and lower sides) may be under pressure at the same time. If the state detection unit detects pressure on these positions at the same time, it will generate a trigger signal and transmit it to the camera. At this point the camera starts and captures images. Although the face detection unit will not think that the user will use the mobile phone after the face detection is carried out on the image collected, so the unlocking control signal will not be sent to the unlocking unit to unlock the keyboard, but if two or more of the mobile phone If a predetermined position is constantly or frequently under press...

Abstract

The invention provides a method and device for automatically unlocking a mobile terminal keyboard, aiming to automatically unlock a keyboard when a mobile terminal is to be used. The device comprises a state detection unit, a camera, a face detection unit and an unlocking unit, wherein the state detection unit detects the stressed state or moving state of the mobile terminal, whether the mobile terminal is in a hand-held state is identified according to the stressed state or the moving state, and a trigger signal is generated when the mobile terminal is in the hand-held state; the camera is used for receiving the trigger signal and collecting images according to the trigger signal; the face detection unit is used for detecting a face according to the images collected by the camera, and an unlocking control signal is generated when the collected images comprise a face image of the preset ratio size; and the unlocking unit is used for receiving the unlocking control signal and carrying out automatical unlocking on the locked keyboard according to the unlocking control signal. According to the invention, the keyboard can be automatically unlocked by identifying the hand-held state of the mobile terminal.

Description

technical field [0001] The present invention relates to a technology for unlocking a keyboard in a mobile terminal, more specifically, to a method and a device for automatically unlocking a keyboard of a mobile terminal, and a mobile terminal including the device. Background technique [0002] At present, almost all mobile terminals (such as mobile phones) have functions of automatically locking the keyboard and manually locking the keyboard. Usually, if the user does not press any keys within a given period of time, the system will automatically lock the keyboard to prevent the user from misoperation; Manual locking of the keypad. Once the keyboard of the mobile terminal is in the locked state, the keyboard of the mobile terminal can enter into a normal working state only after the keyboard is manually unlocked through a specific key, thereby effectively preventing misoperation of the keys by the user. [0003] However, in the prior art, after the keyboard is locked, the ...
