## Background
BACKGROUND
1. Field of the Disclosure
The disclosure relates to the field of smart mobile apparatus, and in particular, to a method for quick photographing based on a mobile apparatus, a device for quick photographing based on a mobile apparatus, and a mobile apparatus.
2. Discussion of the Background Art
Presently, photographing is one of the core functions of a mobile apparatus. Generally, a user utilizes the mobile apparatus to photograph with the followings steps: activating a camera application in the case where the mobile apparatus is in a normal operating state, focusing on a scene, and clicking to photograph.
In some situations such as image capturing, the user may need to photograph a current scene quickly; accordingly, the user needs to utilize the mobile apparatus to perform a quick photographing. In a conventional method for quick photographing, a certain physical button on the mobile apparatus is set as a shortcut key for photographing; the shortcut key is pressed to activate the camera application, in the case where the mobile apparatus is in a non-black-screen state; and then the user manually performs a photographing. Alternatively, in the case where the mobile apparatus is in the non-black-screen state, a certain physical button such as a volume button is set as the shortcut key for photographing; the camera application is activated after the shortcut key is long-pressed for a certain time; and then the user manually performs a photographing.
It can be seen that in the conventional technology, at least two processes of activating the camera application and pressing the photographing button are required when using the mobile apparatus to perform a quick photographing, and an extra process of focusing needs to be performed by the user. A fleeting scene or a scene required to be captured may not be captured because the photographing has too many processes and takes too much time. Therefore, in the conventional technology, the processes for quick photographing are cumbersome and the quick photographing can not be well achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, technical schemes in embodiments of the present disclosure are described clearly and completely in conjunction with drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part of rather than all of the embodiments of the present disclosure. Any other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative effort shall fall within the scope of protection of the disclosure.
A method for quick photographing based on a mobile apparatus is provided according to an embodiment of the disclosure. As shown in FIG. 1, the embodiment includes steps S101 to S105.
Step S101 is to detect a current state of the mobile apparatus if it is detected that a preset physical button is pressed for a duration longer than a preset threshold.
No matter what state the mobile apparatus is in, a system program in the mobile apparatus continually detects a state of the preset physical button. The preset physical button is any mechanical physical button pre-provided on the mobile apparatus, and the state of the preset physical button is detected continually by the system program in any state. In the case where the preset physical button is in a long-pressed state, a quick photographing program is triggered. Therefore, the state of the preset physical button is used as a condition for determining whether a quick photographing is to be triggered.
The long-pressed state is a state that the preset physical button is pressed for a duration longer than the preset threshold. In the case where the system program detects that the preset physical button is switched from a released state to a pressed state, a duration in which the preset physical button maintains in the pressed state is timed. In the case where the duration in which the preset physical button maintains pressed is longer than the preset threshold, it is considered that the preset physical button is long-pressed by the user and it is determined that the preset physical button is in the long-pressed state, and a quick photographing procedure is triggered. The preset threshold is a time threshold preset by an engineer for determining whether the preset physical button is in the long-pressed state. The length of the preset threshold may be set by the engineer, such as 2 s, 2.5 s, which is not limited herein.
After it is determined that the preset physical button is in the long-pressed state, the system program detects a current state of the mobile apparatus. The current state of the mobile apparatus may include a normal operating state and a standby state. The standby state may include three kinds: a black-screen and non-screen-lock-password state, a black-screen and screen-lock-password state and a non-black-screen and screen-lock-password state.
A black-screen state is a state in which the mobile apparatus turns off screen brightness to save power of the mobile apparatus. A screen-locked state is a state in which a password is set by the user for the mobile apparatus to ensure security of the user and the mobile apparatus enters the normal operating state after the mobile apparatus is unlocked with the inputting of the password. The normal operating state is a state that the mobile apparatus is in a non-black-screen and screen-unlocked state and any function of the mobile apparatus can be used normally.
Step S102 is to control the mobile apparatus to enter the normal operating state in the case where the mobile apparatus is in the standby state.
In the case where the system program detects that the mobile apparatus is in the standby state, the mobile apparatus is controlled to enter the normal operating state. That is to say, no matter what kind of standby state the mobile apparatus is in, the mobile apparatus is set by the system program to enter the normal operating state, i.e., the non-black-screen and screen-unlocked state. A camera function may be used by the user normally only in the case where the mobile apparatus is in the normal operating state.
Step S103 is to activate a camera, control the camera to enter a quick photographing mode, and display a preview picture of a current scene, in the case where the mobile apparatus is in the normal operating state.
Controlling the camera to enter the quick photographing mode specifically includes setting a quick photographing flag of the camera as valid to control the camera to enter the quick photographing mode.
In the case where the system program detects that the mobile apparatus is in the normal operating state, the quick photographing flag of the camera is set to be valid, and information that the quick photographing flag is valid is transmitted to a camera program in the system program, and the camera program in the system program enables the camera to enter the quick photographing mode upon reception of the information that the quick photographing flag of the camera is valid.
After the camera is activated and enters the quick photographing mode, the current scene is captured by the camera via a lens of the mobile apparatus and a preview scene is displayed on a screen of the mobile apparatus. The user may move the mobile apparatus based on needs, so that the preview scene is a required scene of the user.
Step S104 is to detect a state of the preset physical button.
In the quick photographing mode, the photographing mode of the camera is different from a normal photographing mode. The system program may not detect a state of a photographing button of the camera, but detects the state of the preset physical button. In the case where it is detected that the preset physical button is released, the current scene is photographed.
Step S105 is to photograph the current scene in the case where the preset physical button is in a released state.
When the user considers that the preview scene displayed currently on the mobile apparatus is the required scene, the user may release the preset physical button. After the quick photographing mode is entered, the system program may detect the state of the preset physical button continually. In the case where the system program detects that the preset physical button is switched from the long-pressed state to a released state, the photographing is initiated, the current scene is photographed and stored into an album.
In the method for quick photographing based on the mobile apparatus provided in the disclosure, the long-pressed state of the preset physical button is set as a triggering condition for the quick photographing, the current state of the mobile apparatus is detected and processes are respectively performed based on different states of the mobile apparatus, and then the camera is activated to enter the photographing state; therefore, the method is applicable to the mobile apparatus in any state to perform quick photographing. Moreover, after the camera is activated, the current scene is photographed if it is detected that the preset physical button is released, while the user does not need to manually click the photographing button again for photography. Therefore, the user merely needs to long-press the preset physical button and release the preset physical button when necessary, to implement the quick photographing. Only one operation is required in the whole procedure, which is simple and quick, thereby achieving the quick photographing effectively.
A method for quick photographing based on a mobile apparatus is provided according to another embodiment of the disclosure. The processes in the embodiment are substantially same as those in the embodiment as shown in FIG. 1. The step S102 in the embodiment as shown in FIG. 1 may be preferably implemented by the following steps S201 to S205 as shown in FIG. 2.
In step S201, it is determined whether the mobile apparatus is in a black-screen state; step S202 is performed in the case where the mobile apparatus is in the black-screen state; or step S203 is performed in the case where the mobile apparatus is in a non-black-screen state.
In step S202, the mobile apparatus is controlled to enter the non-black-screen state in the case where the mobile apparatus is in the black-screen state.
In the case where the mobile apparatus is in the black-screen state, the screen of the mobile apparatus is lighted up to control the mobile apparatus to be in the non-black-screen state.
In step S203, it is determined whether a screen lock password is set for the mobile apparatus, in the case where the mobile apparatus is in the non-black-screen state; step S204 is performed in the case where a screen lock password is set; or step S205 is performed in the case where no screen lock password is set.
In step S204, an unlocking process is skipped and the mobile apparatus is controlled to enter the normal operating state, in the case where the screen lock password is set for the mobile apparatus.
In the case where the screen lock password is set for the mobile apparatus, the camera is activated until the unlocking is performed by the user in ordinary circumstances in view of security. To implement a quick photographing, in the method, the unlocking process is skipped and the normal operating state is entered directly.
In step S205, the mobile apparatus is controlled to enter the normal operating state, in the case where no screen lock password is set for the mobile apparatus.
No matter what kind of standby state the mobile apparatus is in, the mobile apparatus is controlled to enter the normal operating state, i.e., the non-black-screen and screen-unlocked state.
The above embodiment may further include a process of recording an original state of the mobile apparatus. Since the original state of the mobile apparatus may include, for example, the black-screen state, the non-black-screen state, a screen-locked state and a screen-unlocked state, the process may be practically performed after each operation with which the original state is determined. For example, it may be recorded that the original state of the mobile apparatus is the black-screen state, in the case where it is determined that the mobile apparatus is in the black-screen state in the step S202 of the embodiment.
Based on the above embodiment and in conjunction with the process of recording the original state of the mobile apparatus, a specific implementation of the step S102 may include steps S301 to S306 as shown in FIG. 3.
In step S301, it is determined whether the mobile apparatus is in the black-screen state; step S302 is performed in the case where the mobile apparatus is in the black-screen state; or S303 is performed in the case where the mobile apparatus is in the non-black-screen state.
In step S302, it is recorded that the original state of the mobile apparatus is the black-screen state, the mobile apparatus is controlled to enter the non-black-screen state, and step S304 is performed.
It is recorded that the original state of the mobile apparatus is the black-screen state, in the case where it is determined that the mobile apparatus is in the black-screen state. Specifically, it is recorded that the original state of the mobile apparatus is the black-screen state by setting a black-screen flag as valid.
In step S303, it is recorded that the original state of the mobile apparatus is the non-black-screen state, and step S304 is performed.
It is recorded that the original state of the mobile apparatus is the non-black-screen state, in the case where it is determined that the mobile apparatus is in the non-black-screen state. Specifically, it is recorded that the original state of the mobile apparatus is the non-black-screen state by setting the black-screen flag as invalid.
In step S304, it is determined whether a screen lock password is set for the mobile apparatus.
In step S305, it is recorded that the original state of the mobile apparatus is the screen-locked state, the unlocking process is skipped, and the mobile apparatus is controlled to enter the normal operating state.
It is recorded that the original state of the mobile apparatus is the screen-locked state, if it is determined that the screen lock password is set for the mobile apparatus. Specifically, it is recorded that the original state of the mobile apparatus is the screen-locked state by setting a screen lock flag as valid.
In step S306, it is recorded that the original state of the mobile apparatus is the screen-unlocked state, and the mobile apparatus is controlled to enter the normal operating state.
It is recorded that the original state of the mobile apparatus is the screen-unlocked state, if it is determined that no screen lock password is set for the mobile apparatus. Specifically, it is recorded that the original state of the mobile apparatus is the screen-unlocked state by setting the screen lock flag as invalid.
In the embodiment, the original state of the mobile apparatus is recorded before the mobile apparatus performs a quick photographing operation, and the mobile apparatus may be controlled to restore to its original state after the quick photographing operation is completed.
In conjunction with the embodiment as shown in FIG. 3, in another method for quick photographing based on a mobile apparatus provided in the disclosure, after the current scene is photographed, the method further includes a process of controlling the mobile apparatus to restore to the original state of the mobile apparatus. As shown in FIG. 4, the process includes steps S401 to S405.
Step S401 is to determine the original state of the mobile apparatus which is recorded before the photographing.
In step S402, the camera is closed and then the mobile apparatus is controlled to enter the screen-locked state, in the case where the original state of the mobile apparatus is the screen-locked state.
In step S403, the camera is closed and the mobile apparatus enters a main interface or other interfaces, in the case where the original state of the mobile apparatus is the screen-unlocked state.
In step S404, the camera is closed and then the mobile apparatus is controlled to enter the black-screen state, in the case where the original state of the mobile apparatus is the black-screen state.
In step S405, the camera is closed and the mobile apparatus enters the main interface or other interfaces, in the case where the original state of the mobile apparatus is the non-black-screen state.
For ensuring security of the mobile apparatus, the camera program is closed after the quick photographing operation is completed. The state of the mobile apparatus, which is recorded before the photographing, is determined by the system program. If the state of the mobile apparatus recorded before the photographing is the screen-locked state, it indicates that a screen lock password is set by the user, and the mobile apparatus is controlled by the system program to enter the screen-locked state for ensuring security of the mobile apparatus. If the state of the mobile apparatus recorded before the photographing is the screen-unlocked state, the main interface or other interface is entered directly, or the photographed scene is displayed. If the state of the mobile apparatus recorded before the photographing is the black-screen state, the mobile apparatus is controlled to enter the black-screen state after the camera is closed. If the state of the mobile apparatus recorded before the photographing is the non-black-screen state, the main interface or other interface is entered directly.
In conjunction with the embodiment as shown in FIG. 3, in another method for quick photographing based on a mobile apparatus provided in the disclosure, after the current scene is photographed, the method further includes a process of controlling the mobile apparatus to restore to the original state of the mobile apparatus. As shown in FIG. 5, the process includes steps S501 to S506.
In step S501, it is determined whether the screen lock flag is valid.
The original state of the mobile apparatus includes the black-screen state, the non-black-screen state, the screen-locked state and the screen-unlocked state. In practical implementation, it is determined whether the mobile apparatus is in the screen-locked state or the screen-unlocked state by determining whether the screen lock flag is valid or not, and it is determined whether the mobile apparatus is in the black-screen state or the non-black-screen state by determining whether the black-screen flag is valid or not.
In an embodiment of the disclosure, it may be uniformly adopted that a flag set to ‘1’ indicates that the flag is valid and a flag set to ‘0’ indicates that the flag is invalid.
In step S502, the camera is closed and the mobile apparatus is controlled to enter the screen-locked state, in the case where the screen lock flag is valid.
In practical implementation, in the case where the screen lock flag is valid, that is, the screen lock flag is set to ‘1’, the camera is closed and then the mobile apparatus is controlled to enter the screen-locked state.
In step S503, the camera is closed and the mobile apparatus enters the main interface or other interface, in the case where the screen lock flag is invalid.
In practical implementation, in the case where the screen lock flag is invalid, that is, the screen lock flag is set to ‘0’, the camera is closed and then the mobile apparatus enters the main interface or other interface.
In step S504, it is determined whether the black-screen flag is valid.
In step S505, the camera is closed and then the mobile apparatus is controlled to enter the black-screen state, in the case where the black-screen flag is valid.
In practical implementation, in the case where the black-screen flag is valid, that is, the black-screen flag is set to ‘1’, the camera is closed and then the mobile apparatus is controlled to enter the black-screen state.
In step S506, the camera is closed and then the mobile apparatus is controlled to enter the main interface or other interface, in the case where the black-screen flag is invalid.
In practical implementation, in the case where the black-screen flag is invalid, that is, the black-screen flag is set to ‘0’, the camera is closed and then the mobile apparatus enters the main interface or other interface.
The original state of the mobile apparatus is recorded by using the flags in the embodiment, which is simple and practical. After the photographing is completed, the original state of the mobile apparatus is obtained by determined whether the flags are valid or not, and the mobile apparatus is restored to the original state. The flag is a character of one byte, which takes up less memory and is convenient to use. Therefore, the mobile apparatus may be restored to the original state simply and conveniently with the method.
