Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a method for generating image information according to the present invention is shown, and specifically may include the following steps:
101, when a specified operation event aiming at a physical key is monitored, waking up an operating system in a dormant state;
it should be noted that the physical key may be a key having physical hardware, as opposed to a virtual key, i.e., a physical key.
In the embodiment of the invention, the user can trigger the electronic equipment to automatically generate the image information by performing specified operation on the physical key.
In a preferred example of the embodiment of the present invention, the specified operation event of the physical key may include at least one of a double-click event of a volume key and a long-press event of the volume key.
In this example, the physical key may be a volume key, i.e., a key for adjusting the volume.
If the user clicks a physical key, a key event (KeyEvent) may be triggered, for example, if an UP key of a VOLUME key is triggered, a keymode _ VOLUME _ UP event may be triggered, and if a DOWN key of the VOLUME key is triggered, a keymode _ VOLUME _ DOWN may be triggered.
If the same key event is received twice within a preset time period (such as 500ms), it may indicate that a double-click event of the physical key is triggered; a series of identical key events received within a preset time period (e.g., 500ms) may indicate that a long press event of the physical key has been initiated.
Of course, the physical keys and the designated operation events thereof are only examples, and other physical keys and the designated operation events thereof may be set according to actual situations when the embodiment of the present invention is implemented. In addition, besides the above physical keys and their designated operation events, those skilled in the art may also adopt other physical keys and their designated operation events according to actual needs, and the embodiment of the present invention is not limited to this.
In a preferred embodiment of the present invention, step 101 may comprise the following sub-steps:
substep S11, when a key event for the physical key is monitored, sending the characteristic information that the operating system is in a dormant state to the window manager;
substep S12, when the window manager determines from the characteristic information that the operating system is in a sleep state, starting a thread;
substep S13, a power service is invoked by the thread.
When the native operating system is in a dormant state, triggering the physical key generally does not wake up the operating system.
In the interpenet keybefore disparting method of PhoneWindowManager, the accessory condition (i.e. feature information) of the physical key is obtained, if the media service is not called, the telephone service is not called, and the power service is not called, a thread is started, the power service is called in the run method of the thread, and the screen is lighted.
In a preferred embodiment of the present invention, the sub-step S11 may include the following sub-steps:
step S111, reporting the key event of the physical key to an input process;
substep S112, when the operating system is in a sleep state and the proxy state is not refused to receive the input event, changing the proxy state to receive the input event by the input process;
substep S113, sending the characteristic information of the operating system in the dormant state to the window manager by the input process
In a specific implementation, when a key event of a physical key is monitored, the key event may be reported to an input process.
If the user presses the DOWN key of the VOLUME key, the key event key _ VOLUME _ DOWN of the DOWN key of the VOLUME key may be reported to the Input process.
The input process may determine that the operating system state is in the sleep state under the conditions that the media service (media) is not called (idle), the phone service (phone) is not called (idle), the power service (power) is not called, and the like.
Generally, one recipient is required at the time of broadcasting an event. If the operating system is in a sleep state, the proxy state is generally a decision to receive an input event, which may indicate that no receiver currently receives an input event. If the broadcast event occurs, it is filtered out by the operating system.
In the embodiment of the invention, the agent state is modified to be the event of receiving input at the input layer, which can represent the event that the receiver receives input currently, so that the requirement of the operating system is met and the event cannot be filtered by the operating system.
The Input process sends feature information that the operating system is in a dormant state to an instance of a windows manager (phonewindowmanger).
In a preferred example of the embodiment of the present invention, the thread may be a delayed thread, and in this example, the sub-step S13 may include the following sub-steps:
and a substep S131 of calling a power service after a preset time through the delay thread.
In this example, when the physical key is triggered, a counter (count) may be started to count, a delay thread process may be invoked, the delay thread is started after a preset time (e.g., 1s), and a long-press event of the physical key (e.g., a volume key) may be simulated.
The power service is called in the run method of the delayed thread, illuminating the screen.
Step 102, setting specified information in the operating system;
in practical applications, since different processes cannot directly transfer data, specific information (commonly referred to as a flag bit) can be set in the operating system for transferring data in different application processes.
In the embodiment of the present invention, if it is determined that the behavior is initiated by the physical key to generate image information, the operation system may set the specific information for identification, for example, set the value of the custom field "burst _ capture" to true.
Step 103, starting an image processing module;
in a particular implementation, the image processing module may be started by an Intent mechanism of the operating system.
In a preferred embodiment of the present invention, step 103 may comprise the following sub-steps:
a substep S21 of determining whether the image processing module is in a background mode; if yes, performing the substep S22, otherwise, performing the substep S23;
substep S22, calling onResume function to start the image processing module;
sub-step S23, calls onCreate function and onResume function to start the image processing module.
In practical application, there are 7 life cycles in the operating system, which are:
onCreate,onStart,onRestart,onResume,onPause,onStop,onDestory；
if the image processing module is exited by pressing the Home key last time, switching to the background is called.
For image processing modules, two life cycles, the onCreate function, which can be used to open an exclusive device (image hardware), and the onCreate function, which is mainly used to respond to a WM _ Create message, are actually concerned, and the onCreate function, which can be used to open an exclusive device (image hardware), sends a WM _ Create message to the operating system after a window is created (Create).
If the image processing module does not run in the background, the image processing module needs to be started up in the moment to normally call two life cycles of an onCreate function and an onResume function.
If the image processing module is started last time and then returns by pressing the Home key, the image processing module is actually in the background, and at this time, the image processing module is started and the onResume function needs to be called.
Step 104, reading the specified information to enter a specified mode of the image processing module;
by applying the embodiment of the invention, a designated mode for generating the image information can be preset, and the designated mode can specify information such as a flow and parameters for generating the image information.
If the operating system has the designated information, the user can be judged to perform the designated operation on the physical key, the electronic equipment is triggered to automatically generate the image information, and the preset designated mode is continuously executed to generate the image information.
If the operating system does not have the designated information, the electronic equipment can be triggered to automatically generate the image information without continuously executing the preset designated mode by judging that the user does not perform the designated operation on the physical key.
For example, when the value of the custom field "burst _ capture" is true, it may be determined that the user has triggered the electronic device to automatically generate image information by performing a specified operation on a physical key.
In a preferred embodiment of the present invention, step 104 may comprise the following sub-steps:
and a substep S31 of reading the designation information to enter a designation mode of the image processing module when the onResume function is called to start the image processing module.
Because the starting processes of the image processing module in the background are different, the conflict of the life cycle exists. Therefore, in order to be compatible with the two cases, in the embodiment of the present invention, the specified information in the operating system may be read uniformly when the onResume function is called, for example, the judgment is performed by using the value of the custom field "burst _ capture" of the operating system.
According to the embodiment of the invention, when the onResume function is called to start the image processing module, the specified information is read to perform the preset specified module, so that the conflict of starting the image processing module to the generation period under different conditions is avoided, and the practicability is improved.
And 105, driving image processing hardware by the image processing module to generate image information in the specified mode.
In practical applications, the image processing hardware may be disposed in the electronic device, controlled by the image processing module, and may be used to generate image information for a specific object.
After the image processing module is started, the image processing module can drive corresponding hardware equipment (namely image processing hardware) to generate image information.
Specifically, an optical image generated by a SCENE (SCENE) through a LENS (LENS) of image hardware is projected onto the surface of an image Sensor (Sensor), then converted into an electric signal, converted into a digital image signal after A/D (analog-to-digital conversion), and compressed and converted into a specific image file format for storage in a digital signal processing chip (DSP) or a coding library.
In a preferred embodiment of the present invention, step 104 may comprise the following sub-steps:
a substep S41 of starting a generated image mode of the image processing module;
generally, the image processing module may include a plurality of application modes, for example, an image generation mode (image information may be generated), a video recording mode (video information may be generated), a panoramic image generation mode (panoramic image information may be generated), and the image generation mode is selected by the embodiment of the present invention to generate the image information.
In a preferred embodiment of the present invention, the sub-step S41 may include the following sub-steps:
substep S411, when the image processing module is in a background mode, switching the image processing module to an image generation mode;
if the image processing module is in the image recording generation mode or the panoramic image generation mode before the Home key is pressed, the operation of switching back to the image processing module is started again, and the operation is generally automatically restored to the previous operation according to the design of an operating system, namely, the operation is returned to the image recording generation mode or the panoramic image generation mode.
Therefore, for such a situation, the embodiment of the present invention may automatically switch back to the image generation mode after determining that the image processing module is in the background mode, and if the image processing module is not in the background mode, the image generation mode may be opened after the image processing module is started, thereby improving the practicability.
It should be noted that the image processing module may be in the image generation mode before entering the background mode, and the image generation mode may also be switched according to the embodiment of the present invention, which is not limited in this embodiment of the present invention.
And a substep S412 of entering an image generation mode when the image processing module is not in the background mode.
If the image processing module is not in the background module, the image processing module can be started and then directly enter an image generating mode.
According to the embodiment of the invention, after the image processing module is judged to be in the background mode, the image generation mode can be automatically switched back, and if the image processing module is not in the background mode, the image generation mode can be opened after the image processing module is started, so that the practicability is improved.
A substep S42 of starting the image processing hardware in a power-on standby state by the image processing module;
image processing hardware typically has three states, idle, standby, and running. The idle is in a power-down state and is in a complete non-working state, the standby state is in a power-on standby state, and running is in a complete working state.
The starting of the image processing hardware needs to call the data of the frame layer, then call the data of the HAL (hardware abstraction layer) layer, then call the driver drive, and finally start the hardware.
Additional time is consumed because the hardware device needs to initialize many registers when it is first powered up.
By applying the embodiment of the invention, the image processing hardware can be always in a standby power-on state from the beginning of initialization.
In a specific implementation, the image processing hardware can be started by bringing in an action event in the event through a StartActivity method provided by an operating system. The action event may be an event for starting image processing hardware.
In the embodiment of the invention, the image processing hardware in the power-on standby state is directly started, so that the initialization work of a plurality of registers is saved, the time for starting the image processing hardware is reduced, and the speed for starting the image processing hardware is improved.
A substep S43, sending an image generation request to drive the image processing hardware to generate one or more frames of image information after the image processing hardware is started;
