[0030] Specific embodiments of the present invention will be further described in detail below.
[0031] At present, mobile terminals basically have a recording function, and the recording process is realized by pressing buttons to start, pause, continue, and end operations. In the standby state of the mobile terminal, the screen of the mobile terminal is turned off, and in the standby state, most of the functional modules of the mobile terminal are turned off, only retaining those functions for the mobile terminal to answer calls and receive short messages during the standby process and for the mobile terminal to quickly enter the normal state from the standby state. Some modules required by the power-on state are working normally. Although the background recording can be realized, there is still no feasible way to operate the recording process running in the background in the standby state. To operate the recording process in the standby state, the only way to interrupt the standby state is to press the key In normal working state, the screen of the mobile terminal will be lit up in normal working state, so the black screen operation process of background recording cannot be realized.
[0032] The technical problems to be solved include: how to ensure that the recording and recording control can be carried out normally in the standby state; and in the standby state, how to pause and continue the recording by inputting the control signal of the recording process without pressing the button.
[0033] The present invention utilizes the black screen recording function realized by the mobile terminal. The mobile terminal includes a screen, a recording module, a storage module and a non-button sensing module that can act without the user's buttons, such as Figure 1 Shown include the following steps:
[0034] a. Black screen recording startup steps: start the mobile terminal to enter the black screen recording state, the screen is turned off, but the recording module and non-button sensing module work normally, and the recording module starts recording;
[0035] b. black screen recording control step: by changing the external environment where the mobile terminal is located, triggering the non-button sensing module to realize the control of pausing the recording and continuing the recording during the recording process;
[0036] c. Black screen recording end steps: turn off the black screen recording function, and save the recording file to the storage module.
[0037] At present, there are devices or devices on mobile terminals that allow users to perform simple operations on mobile terminals without pressing keys, such as non-button sensing modules such as gravity sensing devices, light sensing devices, acoustic sensing devices, and direction sensing devices (such as gyroscopes). After the invention starts the black screen recording function, on the one hand, the mobile terminal enters the black screen recording state, turns off the screen and other modules that are not necessary for black screen recording, and on the other hand calls the operating system API (API: Application Programming Interface application program programming interface) that prohibits CPU sleep The interface is different from the usual standby state, so that the CPU can still work normally after entering the black screen recording state, ensuring the normal operation of non-button sensing modules such as gravity sensing devices, light sensing devices, and recording modules, and maintaining the control of gravity, sound and light, etc. Real-time sensing of external environmental factors. In the normal standby state, the functions of the above-mentioned CPU and non-key sensing modules are all turned off.
[0038] In the black-screen recording control step, when external environmental factors change, these non-button sensing modules detect these changes, and can output sensing signals to control recording pause or continuation.
[0039]Specifically, when the non-button sensing module includes at least one of a gravity sensing module, a light sensing module, an acoustic sensing module, and a direction sensing module; the b. recording control step changes the gravity, light, sound, and direction of the mobile terminal Wait for the external environment to trigger the non-button sensing module to realize the control of pausing recording and continuing recording during the recording process. The external environmental factors of the changed mobile terminal are the same as the external environmental factors detected by the non-key sensing module. The button sensing module is a gravity sensing module, which changes the relationship between the placement state of the mobile terminal and the direction of gravity, such as flipping or tilting the mobile terminal, allowing the gravity sensing module to output signals to control the pause and continuation of the black screen recording process. When the mobile terminal has multiple non-key sensing modules, these non-key sensing modules can also be pre-set and selected, and only one sensing signal output by the non-key sensing module can be selected to control the pause and continuation of the black screen recording process, avoiding multiple A sensing factor, such as when the sound and light environment of the mobile terminal changes at the same time, misoperation occurs.
[0040] When the user wants to end the recording of the black screen, there is no need for hidden operation at this time, and the mobile terminal can be directly used by pressing the button, and the screen can be lighted up to directly operate to end the recording process of the black screen.
[0041] The present invention also provides a black screen recording mobile terminal, the black screen recording mobile terminal includes a black screen recording control module 1, a non-button sensing module 5, a black screen recording non-essential module 4, a recording module 2 and a storage module 3, such as Figure II shown, where:
[0042] Black screen recording control module: connected to the recording module, non-button sensing module, black screen recording optional module, and storage module, the black screen recording control module is turned on, the mobile terminal enters the black screen recording state, and the black screen recording control module closes the black screen recording optional module, Maintain the normal working status of the non-button sensing module, recording module and storage module;
[0043] Non-button control module: connected to the black screen recording control module, senses external environmental parameters, and outputs sensing signals to the black screen recording control module;
[0044] Non-essential module for black screen recording: including the screen, connected to the black screen recording control module, when entering the black screen recording state, the module is closed;
[0045] Recording module: it is also connected with the storage module to realize the recording of the external environment and store the recording in the storage module;
[0046] Storage module: store recording files.
[0047] Specifically, the non-button control module may include a gravity sensing module to monitor the relationship between the placement state of the mobile terminal and the direction of gravity of the earth. When the mobile terminal is held in a vertical state, or when the mobile terminal is turned over when placed flat, the placement surface changes from the back to the front or from the front to the back, the gravity sensing module will detect and output a sensing signal.
[0048] The light sensing module and the sound sensing module distinguish and monitor the light signal and sound signal of the environment where the mobile terminal is located. For example, the mobile terminal is put into an opaque pocket by the user from a bright place, or the user makes a sound under certain conditions within a short distance. signal, will cause these modules to output sensing signals.
[0049] The direction sensing module monitors the placement direction of the mobile terminal. For example, when the mobile terminal is rotated, the direction sensing module will output a sensing signal. The most common direction sensing module integrated on the mobile terminal is a gyroscope.
[0050] Non-key sensing modules include but are not limited to the above-mentioned types, and can also be, for example, power amplifiers, magnetic field sensing devices, temperature sensing devices, and airflow sensing devices that are only sensitive to certain specific frequency bands.
[0051] When the non-key sensing modules of the black-screen recording mobile terminal of the present invention include more than one type, preferably, the black-screen recording control module also includes a selection module, and the selection module is connected to each of the non-key sensing modules, and only selects one of them The sensing signal of a kind of non-button sensing module is input in the black-screen recording control module, and the concrete realization mode of selection function can be to only keep a non-button sensing module when entering the black-screen recording state, and close the function of other non-button modules; It is to shield the sensing signals of other non-key sensing modules and cannot control the black screen recording process. Users can choose the best way to control the black screen recording function according to different places of use. For example, in entertainment places with dramatic changes in sound and light, it is obviously more reliable to use a gravity sensor module.
[0052] Preferably, the mobile terminal capable of black-screen recording also includes a vibration module 6 connected to the black-screen recording control module. When the black-screen recording is paused and resumed after the pause, the black-screen recording control module will make the vibration module vibrate . Remind the user that the operation of black screen recording is successful. The vibration time should not be too long, for example, the duration should not exceed 0.5 second, so as not to be noticed by others.
[0053] When using a mobile phone to record a black screen, if there is a call from the outside world, the existing mobile phone will automatically enter the normal use state from the standby state. After the mobile phone enters the black screen recording process, turn off the signal receiving device of the mobile phone for receiving external wireless communication signals, so that the communication between the mobile phone and the outside world is temporarily closed, that is, the mobile phone has no signal, and external calls cannot be entered to ensure the black screen recording process. continuous and uninterrupted. For the convenience of the user, when the black screen recording function is activated, the user can also choose not to turn off the signal receiving device.
[0054] When the non-button control module in the mobile terminal is a gravity sensing module, in the b. black screen recording control step of the present invention, the black screen recording function is suspended and continued. Flip over to make the bottom and top sides of the original placement exchange with each other. At this time, the recording of the black screen is paused; when it is necessary to continue, flip and exchange the bottom and top surfaces of the placement again, and the recording of the black screen continues, that is, the gravity sensor module detects the direction of placement of the mobile terminal and the direction of gravity If the included angle changes by 180 degrees, it is considered that the black screen recording process needs to be paused or continued, and an induction signal is sent to the black screen recording control module to control the black screen recording process to pause or continue. The method is simple, reliable, easy to control, reduces the operation difficulty of the user, and is not easy to attract the attention of others.
[0055] Preferably, the method for realizing black-screen recording on the mobile terminal described in the present invention, in c. in the end step, the mode of saving the recording file is to encrypt and save. The storage module of the present invention includes an encryption device and a storage device, the encryption device is connected between the signal input end of the storage module and the storage device, and the input recording information is encrypted and stored in the storage device, in view of the special aspect of the present invention In the use environment, the encrypted storage of recording files is the preferred storage method for most users.
[0056] The black screen recording control module in the black screen recording mobile terminal of the present invention can be a separate hardware control module, such as an integrated circuit chip with a separate design and wiring; All terminals have a central processing unit (CPU), memory and storage devices. Users store the pre-written software program in the mobile terminal, start the program when using it, and call the above hardware resources of the mobile terminal to form a pair The black-screen recording control module that controls the black-screen recording process, so the method for realizing black-screen recording on the mobile terminal according to the present invention can be realized not only in the black-screen recording mobile terminal of the present invention, but also in other devices with a central processing unit, The function of black screen recording can also be realized by inputting pre-written software on the mobile terminal of the internal memory and storage device, and mobile terminals with the above-mentioned configurations are very popular at present. The inventor has realized the black screen recording function by using several common mobile terminals on the market and inputting computer software programs. The inventor uses computer languages such as Objective-C, JAVA, C# to write programs and input them into the mobile terminal to realize the black screen recording function. Among them, JAVA is aimed at mobile terminals using the Android operating system, C# is aimed at mobile terminals using the Windows Phone operating system, Objective-C is aimed at mobile terminals using the IOS operating system; Android, Windows Phone, and IOS are all aimed at mobile terminals. The mobile terminal operating system developed by the terminal environment.
