Description
Technical Field
The present invention relates to an electronic device and an operating method thereof, and more particularly, to an electronic device capable of reviewing a history image after lock screen photographing and an operating method thereof.
Background
With the development of electronic devices, various functions, such as photographing, video recording, communication, and the like, have been integrated on the electronic devices. In order to ensure the privacy and security of information in an electronic device, the screen of the electronic device may be locked in an encrypted manner, usually when the electronic device is not used for a long time or according to the active requirements of a user.
When the screen is in the encryption locked state, if it is desired to use a function in the electronic apparatus, it is first necessary to unlock the locked screen, which is inconvenient for the user. Especially when the user needs to utilize some functions in the apparatus (such as taking a picture) in a more urgent state, the unlocking operation makes it possible for the user to miss the subject that wants to be taken.
In this regard, some electronic devices have been designed to use some of the functions of the device in a screen-encrypted locked state. For example, a shortcut icon indicating a camera may be displayed on a screen of the electronic device when the screen is in a cryptographically locked state, and a user may directly select the icon to photograph using a camera built in the electronic device without unlocking the screen. In this case, the shot photos are typically stored in a default image storage application (such as an album) in the device, and when the shooting is completed, the user can invoke the image storage application to review the shot photos.
However, when the user reviews the shot pictures with the screen in the encryption locked state, the functions of the image storage application are usually not fully invoked for security reasons, and the user can only view one or more pictures shot this time after locking the screen, but cannot view previously shot pictures or stored images. If the user wants to view or use the images shot or stored before together, the user needs to go back to the screen locking interface, unlock the screen and enter the image storage application for viewing. For the user, not only the operation is too cumbersome, but also more importantly, even if the user enters the image storage application after unlocking, the user cannot directly locate the position of the image to be viewed, and the user still needs to search for the desired image from the beginning, so that the viewing rhythm of the user is interrupted, and the efficiency is low.

Hereinafter, an electronic device capable of reviewing a history image after lock screen photographing and an operation method thereof according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 4.
Fig. 1 is a block diagram illustrating an electronic device 100 according to an embodiment of the present disclosure.
According to the embodiment of the present invention, the electronic device 100 may be a portable electronic device such as a mobile phone, a tablet computer, a personal digital assistant, and the like, but is not limited thereto. Furthermore, for ease of explanation, the electronic device 100 using a touch screen display will be described below as an example, however it should be understood that the present invention is not limited thereto, and the aspects of the present invention are applicable to any electronic device having a camera function.
Referring to fig. 1, an electronic device 100 according to an embodiment of the present disclosure includes a camera unit 101 and a control unit 102.
As shown in fig. 1, the camera unit 101 may capture an image and store the captured image in the electronic device while the screen is in a locked state.
In particular, according to an exemplary embodiment of the present invention, after the electronic device 100 enters the lock screen state, a user may be provided with a shortcut to use some functions in the electronic device 100 under the lock screen interface. For example, an icon indicating a camera (as shown in fig. 4 b) is provided on the lockable screen interface, so that the user can select the icon directly to implement the camera function in the locked screen state without unlocking the screen into the main screen to select and use the camera function. In this case, the camera function may be invoked by selecting (e.g., touching) a camera icon on the lock screen interface. The photographed image may be stored in an image storage application such as an album preset in the electronic device.
Further, in an embodiment of the present invention, if the user desires to review the photographed image in the lock screen state, an image viewing request may be made to the electronic apparatus 100, and the control unit 102 may control the display of the electronic apparatus 100 to display the stored image according to the image viewing request of the user.
Specifically, after image capture is completed in the lock screen state, the user may issue an image viewing request by selecting (e.g., touching) an icon or other indication of an image storage application displayed in association with the camera function. When the control unit 102 receives the image viewing request, the control unit 102 may call the image storage application and display the stored image.
In the embodiment of the present invention, the screen locking state of the screen may be an encrypted screen locking state in which an encrypted information such as a password, a pattern, or a fingerprint is required to unlock, or may be a general screen locking state in which the screen is only disabled without decryption of such encrypted information. The image storage application invoked in the above-described general lock screen state generally has its full function, whereas in the encryption lock screen state, the invoked image storage application can use only a partial function of the application, for example, only an image currently captured in the encryption lock state can be viewed, for security reasons.
However, when the electronic apparatus is in the encryption locked state, the user may also wish to view the image stored before this shooting after having viewed the currently shot image. In this case, when the user continues to request viewing of one or more history images that have been stored before the screen was in the locked state, it is necessary to further call up all the functions of the image storage application. Therefore, according to an embodiment of the present invention in an example, when a user requests to view one or more history images that have been stored before the screen is in the locked state, the control unit 102 may determine whether the electronic apparatus is in the encryption locked state. If the electronic apparatus 100 is not in the encryption locked state, the control unit 102 may directly display the history image requested to be viewed since the function of the image storage application has been fully invoked. If the electronic device 100 is in the encryption locked state, the control unit 102 may provide an unlocking interface to the user and control the display to display a history image that the user requests to view after receiving an unlocking input via the unlocking interface.
For example only, if the electronic device is in the encryption locked state, the control unit 102 may control the display to display a password input interface for instructing the user to input a password on the screen in a case where the electronic device 100 uses a password unlocking scheme. In the case where the electronic device 100 uses the pattern unlocking scheme, the control unit 102 may control the display to display a pattern input interface (e.g., a squared figure unlocking interface) for instructing the user to input a pattern on the screen. In the case where the electronic device 100 uses the fingerprint unlocking scheme, the control unit 102 may activate the fingerprint sensor such that the user may input a fingerprint using the activated fingerprint sensor, at which time, the control unit 102 may also control the display to display a fingerprint input prompt on the screen for indicating the user to input the fingerprint or to display a fingerprint input prompt for indicating the location of the user to input the fingerprint. However, it should be understood that the above manner of providing the unlocking interface is merely an example, and the present invention is not limited thereto, and a corresponding unlocking interface may be provided according to a screen locking manner of the electronic device 100.
Further, in the embodiment of the present invention, the history images stored in the image storage application include not only images captured by the camera unit 101 before the screen is locked but also images obtained and saved by screen-capturing the screen display of the electronic apparatus 100, images obtained and saved by other applications such as wechat, microblog, mail, and the like. These historical images may be stored in the image storage application in a default order (e.g., chronological order) or in a user-set rule (e.g., classification), etc.
With continued reference to fig. 1, according to an embodiment of the present invention, after receiving an unlocking input of the user via the unlocking interface, the control unit 102 may also verify the unlocking input of the user (e.g., whether the password is correct, whether the pattern matches a preset unlocking pattern, whether the fingerprint matches a pre-stored fingerprint, etc.). When the unlock input is correct, the control unit 102 may call the entire function of an image storage application (e.g., an album), locate, based on an image viewing request of the user, a history image that the user requests to view among one or more history images already stored in the image storage application, and control the display to display the history image that the user requests to view based on the result of the location. It should be understood that since the image storage application typically arranges the images according to a default order or rules set by the user, when the user requests to view the history images stored before the lock screen, the control unit 102 can know such arrangement information to realize the positioning of the history images based on the information.
Thus, the image storage application can be directly accessed and positioned to the historical image which is expected to be viewed by the user after the screen lock is released, so that the user can realize seamless image browsing.
Fig. 2 is a flowchart illustrating a method of capturing an image in a screen-locked state and viewing the captured image according to an embodiment of the present disclosure.
Referring to fig. 2, in step 201, an image may be captured using the camera unit 101 of the electronic device 100 with the screen in a locked state.
In step 202, the image captured by the camera unit 101 may be stored in the electronic device 100, for example, in an image storage application (such as an album) in the electronic device 100.
Then, when receiving an image viewing request of the user, the control unit 102 may control the display of the electronic device 100 to display the stored image on the screen according to the image viewing request of the user in step 203.
Hereinafter, a method of reviewing a history image in an electronic device according to an embodiment of the present invention will be described in detail with reference to fig. 3 and 4a to 4 f.
Fig. 3 is a flowchart illustrating a method of reviewing a history image after image capturing is completed in a screen-locked state according to an embodiment of the present disclosure, and fig. 4a to 4f are screen displays illustrating a method of reviewing a history image after image capturing is completed in a screen-locked state according to an embodiment of the present disclosure.
For convenience of explanation, it is assumed that before the electronic device 100 is in the screen-locked state, the image 1, the image 2, and the image 3 are stored in an image storage application (e.g., an album) of the electronic device 100 (as illustrated in fig. 4 a), and after the screen is locked, the user may call the camera unit 101 to capture the image 4 through a shortcut icon provided on the locked screen (as illustrated in fig. 4 b) in the screen-locked state, and may review the captured image 4 after the capturing (as illustrated in fig. 4 c).
Further, in the embodiment of the present invention, the history images (for example, image 1, image 2, and image 3) stored in the image storage application include not only images captured by the camera unit 101 before the screen lock but also images obtained and saved by screen-capturing the screen display of the electronic apparatus 100, images obtained and saved by other applications such as wechat, microblog, mail, and the like. These historical images may be stored in the image storage application in a default order (e.g., chronological order) or in a user-set rule (e.g., classification), etc.
Referring back to fig. 3, after completing image capturing and reviewing one or more currently captured images with the screen in the locked state, if the user continues to request viewing of one or more history images (i.e., image 1, image 2, or image 3) that have been stored before the screen was in the locked state, it may be determined whether the electronic device 100 is in the encryption locked state in step 301.
If the electronic device 100 is not in the encryption locked state (301 — NO), the history image requested to be viewed among the image 1, the image 2, and the image 3 may be displayed on the screen at step 305.
If the electronic device 100 is in the cryptographically locked state (301-yes), the control unit 102 of the electronic device 100 may provide an unlocking interface to the user (as shown in fig. 4 d) in step 302. For example only, in a case where the electronic device 100 uses a password unlocking scheme, the control unit 102 may control the display to display a password input interface for instructing the user to input a password on the screen. In the case where the electronic device 100 uses the pattern unlocking scheme, the control unit 102 may control the display to display a pattern input interface (e.g., a squared figure unlocking interface) for instructing the user to input a pattern on the screen. In the case where the electronic device 100 uses the fingerprint unlocking scheme, the control unit 102 may activate the fingerprint sensor so that the user may input a fingerprint using the activated fingerprint sensor, at which time, the control unit 102 may further control the display to display a fingerprint input prompt indicating that the user inputs a fingerprint or to display a fingerprint input prompt indicating that the user inputs a location of the fingerprint on the screen (as shown in fig. 4 e). However, it should be understood that the above manner of providing the unlocking interface is merely an example, and the present invention is not limited thereto, and the corresponding unlocking interface may be provided according to a specific screen locking manner of the electronic device 100.
At step 303, an unlock input by a user may be received via the provided unlock interface. At this time, the user's unlocking input may also be verified (e.g., whether the password is correct, whether the pattern matches a preset unlocking pattern, whether the fingerprint matches a pre-stored fingerprint, etc.).
When the unlock input is correct, all functions of an image storage application (e.g., an album) may be called and, based on an image viewing request of the user, a history image that the user requests to view is located among one or more history images already stored in the image storage application, and the display is controlled to display the history image that the user requests to view (e.g., image 3, as shown in fig. 4 f) based on the location result, in step 304. It should be understood that since the album is generally arranged according to a default or user-set rule, when the user requests to view the history images stored before the lock screen, the control unit 101 can know such arrangement information to realize the positioning of the history images based on the information.
By applying the scheme of the application, when the history image is required to be reviewed after screen locking shooting is performed, the user can directly enter the album and jump to the position of the history image required to be viewed after the screen is unlocked through the unlocking interface, and therefore the user can feel seamless viewing experience.
The exemplary embodiments of the present invention can also be embodied as computer readable codes on a computer readable recording medium. The computer readable recording medium is any data storage device that can store data which can be thereafter read by a computer system. Examples of the computer-readable recording medium include: read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and carrier waves (such as data transmission through the internet via a wired or wireless transmission path). The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for accomplishing the present invention can be easily construed by programmers of ordinary skill in the art to which the present invention pertains within the scope of the present invention.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
