The embodiments disclosed in this document can be implemented in the mobile terminal 100 described with reference to FIG.

Hereinafter, the control method of the mobile terminal 100 according to the first embodiment of the present invention and the operation of the mobile terminal 100 performing the same will be described in detail with reference to the necessary drawings.

FIG. 2 is a flowchart illustrating a control method of the mobile terminal 100 according to the first embodiment of the present invention, and shows a control method of the mobile terminal 100 related to a phone book. 3 is a diagram for explaining the control method of FIG.

Referring to FIG. 2, the control unit 180 receives a request to enter a phonebook screen from a user through the user input unit 130 (S101).

For example, the controller 180 can receive an entry request for a phone book as an icon corresponding to the phonebook execution function is touched.

In addition, for example, when the home key or the back key included in the user input unit 120 is pressed while another application is running in the foreground, Lt; RTI ID = 0.0 &

When the entry to the phone book is requested, the controller 180 determines whether the phone book is first entered into the phone book (S102). That is, it is confirmed whether or not the phonebook screen is created, and if the phonebook screen is not generated before, it is determined that the phonebook screen is the first entry. On the other hand, when the phone book screen enters the state in which the phonebook screen is created or the display is in the inactive state, it is judged as re-entry.

When entering the phone book screen for the first time, the controller 180 allocates various resources for creating a phone book screen and performs initialization (S103). Also, the phonebook data necessary for the phonebook screen configuration is read from the memory 160 and loaded into the buffer (S105).

On the other hand, when re-entering the phonebook screen, the controller 180 omits the resource allocation and initialization process (S103) and uses the resources allocated at the time of previous entry as it is.

In addition, it is checked whether an update has occurred in the phone book data (S104), and the updated phone book data is loaded again into the buffer only when it is updated (S105).

In step S105, when the phonebook data is obtained, the controller 180 forms a phonebook screen using the acquired phonebook data, and displays the phonebook screen through the display module 151 (S106).

Thereafter, the control unit 180 stops the execution of the phonebook screen and stores the current state (S108) as the screen is switched to a screen other than the phonebook screen (S107).

In step S108, the controller 180 can move the screen from the phonebook screen to the home screen as the home key included in the user input unit 120 is operated.

In step S107, the control unit 180 may move to the previous screen by operating the back key included in the user input unit 120. [

Referring again to FIG. 2, the control unit 180 repeatedly performs the above-described steps S101 to S108 until a finish request for the phonebook screen is received (S109).

Upon receiving the termination request, the resource allocated for the phonebook screen configuration is released and the phonebook screen is terminated (S110).

Meanwhile, according to the first embodiment of the present invention, until the phonebook screen finishes, the phonebook screen remains in a stop or pause state even though the phonebook screen is not displayed on the screen. That is, it maintains the resources allocated for display of the phonebook screen. If the phonebook screen disappears and is displayed again, it is determined that the phonebook screen is re-entered.

On the other hand, if the entry of the phonebook screen is requested after the phonebook screen is terminated, the controller 180 determines that the phonebook screen is initially entered, and proceeds from step S101 again.

Meanwhile, according to the related art, when the back key included in the user input unit 130 is operated while the phone book screen is displayed, the phone book screen is terminated. That is, the resources allocated to the phonebook screen are released. However, according to the first embodiment of the present invention, even if the back key is operated and the screen is moved to another screen in the state that the phone book screen is displayed, as in the case where the home key is operated, And keeps the execution of the Phonebook screen stopped. This is because, when a phonebook screen is newly created, a lot of delay time is generated as compared with the case of re-entry.

FIG. 3 shows an example in which a control method according to the first embodiment of the present invention is applied to an android-based mobile terminal 100. FIG.

3 (a) shows a flow up to displaying a phonebook screen at the time of initial entry on a phonebook screen, and FIG. 3 (b) shows a flow until a phonebook screen is displayed when the phonebook screen is re- .

Referring to FIG. 3A, when the controller 180 first enters the phonebook screen, the controller 180 calls onCreate () (3a). onCreate () This method is called when the phonebook screen is first created. It handles resource initialization and setting of all initial values of the global state.

Thereafter, the control unit 180 calls onResume () (3b) and starts by calling a DB query in onResume (). When the phonebook data is obtained through the DB query, the phonebook screen is drawn (3c) to the display area using the obtained phonebook data. onResume () is called when the phonebook screen is displayed on the screen and immediately before the interaction, and is called when the phonebook screen is located in the foreground. The DB query is a process of loading information necessary for the configuration of the phonebook screen from the memory 160.

On the other hand, referring to FIG. 3B, the controller 180 calls onRestart () instead of onCreate () when re-entering the phonebook screen, and when the update occurs in the phonebook data, Invoke the DB query. onRestart () is a method called when the phonebook screen is inactive and re-entered into the phonebook screen.

Then, the control unit 180 sequentially executes the onResume () 3e and the phonebook screen drawing 3f to display the phonebook screen on the display area.

On the other hand, as shown in FIG. 3, when onCreate () onRestart () is called on re-entry to the phonebook screen, delays occurring in the process of reallocating and initializing resources can be resolved.

Also, by changing the point at which the DB query is called to the onRestart () method instead of the conventional onResume () method, the start point of the DB query can be advanced, and the DB query can be selectively performed only when the update of the phone book data occurs , The time delay due to the DB query can be largely eliminated.

Therefore, according to the first embodiment of the present invention described above, there is an effect that the delay time until displaying the phonebook screen on the screen of the mobile terminal 100 is minimized.

Hereinafter, the control method of the mobile terminal 100 according to the second embodiment of the present invention and the operation of the mobile terminal 100 performing the same will be described in detail with reference to the necessary drawings.

4 is a flowchart illustrating a control method of the mobile terminal 100 according to the second embodiment of the present invention. The control method of the mobile terminal 100 for entering a camera user interface (UI) will be. 5 and 6 are diagrams for explaining the control method of FIG.

Referring to FIG. 5, the controller 180 receives a camera UI entry request (S301). Accordingly, the control unit 180 displays a preparation screen indicating that the preview image is being prepared instead of the preview image of the camera UI through the display module 151 (S302).

Thereafter, the control unit 180 controls the sensor of the camera 121 to acquire an external image (S303), and when the sensor of the camera 121 is activated to acquire an external image, A preview image of the external image is displayed on the screen of the mobile terminal 100 instead of the preparation screen (S304).

In addition, the controller 180 configures some components of the camera UI (S305), and displays the camera UI on the screen of the mobile terminal 100 (S306).

According to the second embodiment of the present invention, the controller 180 separately configures a thread for performing the steps S303 and S304 and a thread for performing the steps S305 and S306, and performs two threads in parallel The delay time can be reduced as compared with the case where the steps S303 to S306 are sequentially performed in one thread.

Referring again to FIG. 4, the components constituting the step S305 are elements displayed on the screen when the user first enters the camera UI, and are distinguished from the components displayed on the screen only when the user's control input is generated.

According to the second embodiment of the present invention, only the elements that are directly displayed on the screen at the time of initial entry into the camera UI are preferentially configured and displayed on the screen through steps S305 and S306, The components that are not displayed on the screen or activated only when the display is activated, but the components necessary for the control of the camera 121 proceed to the configuration after displaying the camera UI on the screen (S307). That is, only the elements that are displayed to the users in the camera UI are preferentially configured and displayed on the screen, and the remaining elements are configured after being displayed on the camera UI screen. Accordingly, as compared with displaying the camera UI on the screen after all the components of the camera UI are configured, the delay time until entering the camera UI is reduced.

FIG. 5 illustrates an example of entering the camera UI in the mobile terminal 100 according to the second embodiment of the present invention.

Referring to FIG. 5, as shown in FIG. 5 (a), the controller 180 displays an icon 5a corresponding to the camera UI execution function on the home screen by the user, . ≪ / RTI >

Accordingly, the control unit 180 reads the pre-stored image from the memory 160 as the initial screen of the camera UI, and displays the initial screen on the screen of the mobile terminal 100 as shown in FIG. 5 (b) .

The initial screen is displayed on the screen until the sensor of the camera 121 is activated and the external image is acquired. When the sensor of the camera 121 is activated, the controller 180, as shown in FIG. 5C, Instead of the initial screen, a preview image acquired through the camera 121 is displayed on the screen.

As described above, when the initial screen image is displayed before the camera UI is prepared, the user recognizes that the mobile terminal 100 is performing something and the psychological time delay until the user's camera UI is displayed on the screen is reduced It is effective.

FIG. 6 illustrates an example in which a control method according to a second embodiment of the present invention is applied to an android-based mobile terminal 100. FIG.

Referring to FIG. 6, according to the second embodiment of the present invention, when the camera UI entry request is made, the controller 180 first configures the camera loading activity (CamLoading activity) 6a before the camera activity configuration .

The screen may be displayed through the display module 151 after onResume () is performed due to the characteristics of the Android.

Conventionally, since a camera UI screen is configured using only one camera activity (cameraApp), there are many operations to be performed for camera UI configuration in onCreate () before onResume (), so that camera UI entry is requested and initial screen switching occurs There was a considerable time delay before.

Accordingly, in the second embodiment of the present invention, the control unit 180 separates the camera loading activity and shares these operations, and after calling onResume () in association with the camera loading activity, By controlling the screen 6b to be displayed, the time delay until the initial screen is displayed is minimized.

After the initial screen is displayed, the control unit 180 starts the camera activity configuration and calls onCreate () (6c) accordingly.

Conventionally, when the camera UI entry is requested, not only the initial settings related to the UI drawing in the onResume () called for the camera activity configuration but also the settings related to the sensor control of the camera 121 are performed by one thread Significant time delay has occurred.

Accordingly, in the second embodiment of the present invention, the initial settings performed in onResume () are divided into a plurality of threads to process the threads in parallel.

Referring to FIG. 5, the control unit 180 performs onCreate () when the camera activity configuration starts, and calls onResume () (6d). It also starts a preview thread 6g associated with camera control.

When the onResume () is completed, the controller 180 displays a preparation screen 6e indicating that the preview image is being prepared on the screen and executes the UI drawing thread 6f. The UI drawing thread 6f constitutes the first graphic elements displayed on the screen when the camera UI screen is initially displayed and performs operations for displaying the graphic elements on the screen.

For example, in the UI drawing thread, a quick function list in which quick execution functions are associated with the camera UI, a main panel constituting a camera UI screen, an indicator displayed on the camera UI screen, ) Are displayed, the graphic elements to be displayed on the screen are configured first.

On the other hand, when a thread related to camera control is started, the control unit 180 activates the sensor of the camera 121 and performs operations 6h and 6i for acquiring an external image therethrough, And generates a preview image of an external image obtained through the image processing unit 121.

On the other hand, the control unit 180 configures the camera UI screen 6j including the graphic elements and the preview image obtained through the threads, and displays the camera UI screen 6j on the screen of the mobile terminal 100. [ When the camera UI screen is displayed, it is determined that the user has entered the camera UI.

The preview image and graphic elements included in the camera UI screen can be displayed sequentially or simultaneously on the screen according to the completion time of each thread. When the preview image is displayed on the screen, the ready screen that was previously displayed is removed from the screen.

On the other hand, conventionally, components that are not displayed on the screen in association with the camera UI before the camera UI screen is displayed, or are displayed only when a user's input occurs are also configured in advance. However, in the second embodiment of the present invention, elements displayed after being displayed on the camera UI screen are displayed only when the user input thread is not displayed on the screen through a user setting thread 6k .

For example, components included in the camera UI in relation to focus, submenu, sound, zoom, storage, brightness, etc. may be displayed on the camera UI screen You can then do this using a separate thread.

According to the second embodiment of the present invention, when the entry of the camera UI is requested, the preparatory screen indicating that the camera UI is preparing is displayed first, thereby making the user feel as if the delay time is psychologically reduced.

In addition, since the operation of controlling the camera sensor and the operations of configuring the screen are performed in parallel, the time delay until the actual camera UI screen is displayed is minimized.

Hereinafter, the control method of the mobile terminal 100 according to the third embodiment of the present invention and the operation of the mobile terminal 100 performing the same will be described in detail with reference to the necessary drawings.

FIG. 7 is a flowchart illustrating a method of controlling the mobile terminal 100 according to the third embodiment of the present invention, and shows a control method of the mobile terminal 100 related to a gallery.

Referring to FIG. 7, the controller 180 receives a gallery entry request from the user through the user input unit 130 (S301).

For example, the controller 180 may receive an entry request for the gallery as the icon corresponding to the gallery execution function is touched.

When receiving the request to enter the gallery, the controller 180 determines whether the coordinate information for constructing the gallery screen is already stored in the cache (S302).

If there is no cache file including the coordinate information constituting the gallery screen, the controller 180 calculates various coordinate information for constructing the gallery screen (S303), and then stores the coordinate information calculated for reuse in the cache (S304).

In addition, the controller 180 forms a gallery screen based on the coordinate information calculated in step S303, and displays the gallery screen on the screen of the mobile terminal 100 through the display module 151 (step S305).

In step S302, if there is a cache file including coordinate information, the controller 180 determines whether the corresponding cache file is valid (S306). If the cache is valid, coordinate information is obtained from the cache (S307), and a gallery screen is constructed based on the coordinate information and displayed on the screen.

On the other hand, if the cache is not valid, the coordinate information constituting the gallery screen is recalculated to construct a gallery screen.

In step S306, the controller 180 may check the size of the cache file or determine the validity of the cache file in which the coordinate information is stored using the MD5 hash.

Generally, it takes a lot of time to calculate the coordinate information of the screen configuration in the process of constructing the gallery screen. Therefore, as described above, when the coordinate information is calculated only once at the time of first entry, and the calculated coordinate information is generated as a cache and reused, the time delay until entering the gallery can be significantly reduced.

Meanwhile, according to the third embodiment of the present invention, in step S306, the control unit 180 may store images and moving images loaded from the memory 160 in a cache to form a gallery screen. In this case, when re-entering the gallery, the process of loading an image or a moving image from the memory 160 to form a gallery screen is omitted, thereby eliminating the time delay in the image loading process.

Hereinafter, the control method of the mobile terminal 100 according to the fourth embodiment of the present invention and the operation of the mobile terminal 100 performing the same will be described in detail with reference to the necessary drawings.

FIG. 8 is a flowchart illustrating a control method of the mobile terminal 100 according to the fourth embodiment of the present invention, and shows a control method of the mobile terminal 100 related to a music list. 9 and 10 are diagrams for explaining the control method of FIG.

Referring to FIG. 8, the control unit 180 receives a music list entry request through the user input unit 110 (S401).

Accordingly, the control unit 180 reads an initial screen image stored in the memory 160 and displays it on the screen in association with the music list before configuring the music list (S402). Here, the initial screen is a screen for displaying to the user that the music list structure is configured before acquiring information from the memory 160. [

Thereafter, the control unit 180 reads information on only a predetermined number of music files stored in the memory 160, and generates a first list using the information (S403). Further, the generated first list is displayed on the screen (S404).

Thereafter, the controller 180 acquires information on remaining music files not included in the first list, and generates a second list including the entire music files based on the information (S405).

Then, the first list displayed on the screen is switched to the second list including the entire music files and displayed (S406).

FIG. 9 shows an example of entering a music file list in the mobile terminal 100 according to the fourth embodiment of the present invention.

Referring to FIG. 9, the controller 180 receives a music UI entry request as the music icon 9a located on the home screen is touched, as shown in FIG. 9 (a).

9B, the control unit 180 reads the initial screen image 9b previously stored in the memory 160 and displays it on the screen before configuring the music list (step < RTI ID = 0.0 > . The initial screen image 9b is generated in advance and stored in the memory 160. [

When the initial screen is displayed, the controller 180 reads the information of the music files from the memory 160 in order to generate a list. Also, the music file list 9c is created based on the read information, and the music file list 9c generated as shown in (c) of FIG. 9 is displayed on the screen.

FIG. 10 shows an example in which a control method according to the fourth embodiment of the present invention is applied to an android-based mobile terminal 100. FIG.

Referring to FIG. 10, when the user enters the music list, the controller 180 calls onCreate, onResume (), or the like to initialize the music list (10a).

Then, the control unit 180 reads the initial screen 10b previously stored in the memory 160 and displays it on the screen before acquiring the information of the music to be included in the music list through the DB query.

When the initial screen is displayed, the controller 180 acquires music file information of a predetermined number through the first DB query 10c, and constructs an initial music file list based on the acquired music file information (10d). Also, the configured initial music file list is displayed instead of the initial screen (10e).

If the initial list is configured, the controller 180 executes the second DB query 10f again to acquire the remaining music file information to be included in the music file list, and construct a music file list to be displayed on the screen based on the remaining music file information 10g). When the final music file list is constructed, the final music file list is displayed on the screen instead of the initial list (10h).

Generally, in order to create a music list, a process of sorting music files according to a predetermined priority is required. If there are many music files included in the list, it takes a considerable amount of time in the sorting process, which increases the time delay until the list is displayed on the screen.

Accordingly, in the second embodiment of the present invention, if the number of music files to be included in the list exceeds a preset number, a list including only the predetermined number of music files is first displayed on the screen to provide a psychological time delay And displays the list generated by sorting the entire music file again while the initial list is displayed, finally on the screen.

Hereinafter, the control method of the mobile terminal 100 according to the fifth embodiment of the present invention and the operation of the mobile terminal 100 performing the same will be described in detail with reference to necessary drawings.

11 is a flowchart illustrating a control method of the mobile terminal 100 according to the fifth embodiment of the present invention, and shows a control method of the mobile terminal 100 related to the message list display. 12 and 13 are diagrams for explaining the control method shown in FIG.

Referring to FIG. 11, the controller 180 receives a message list entry request from the user through the user input unit 130 (S501).

For example, the control unit 180 can receive a message list entry request as the icon corresponding to the execution function of the message application is touched.

Upon receipt of the message list entry request, the controller 180 reads the initial screen associated with the message list from the memory 160 and displays the initial screen through the display module 151 (S502) before generating the message list.

Here, the initial screen is a screen for displaying to the user that the message list is configured before acquiring the message list configuration from the memory 160.

After displaying the initial screen, the controller 180 acquires information necessary for constructing the message list from the memory 160 (S503). In addition, the message list is constructed using the acquired information (S504), and the configured message list is displayed on the screen of the mobile terminal 100 instead of the initial screen (S505).

FIG. 12 shows an example of displaying a message in the mobile terminal 100 according to the fifth embodiment of the present invention.

Referring to FIG. 12, the controller 180 receives a message UI entry request as the message icon 9a located on the home screen is touched, as shown in FIG. 12 (a).

The control unit 180 reads the initial screen image 12b previously stored in the memory 160 and displays it on the screen before constructing the message list as shown in Figure 12 (b) . The initial screen image 12b is generated in advance and stored in the memory 160. [

When the initial screen is displayed, the control unit 180 reads the information for generating the message list from the memory 160. In addition, a message file list 12c is generated based on the read information, and a message file list 12c generated as shown in (c) of FIG. 12 is displayed on the screen.

FIG. 13 shows an example in which the control method according to the fifth embodiment of the present invention is applied to an android-based mobile terminal 100. FIG.

Referring to FIG. 13, when an entry into a message list is requested, the controller 180 performs initialization 13a by calling onCreate (), onStart (), onResume (), or the like.

Then, instead of constructing the list, the controller 180 constructs an initial screen 13b indicating that the user is entering the message list, and displays the initial screen 13b on the screen. After the initial screen is displayed, onPostResume () 13c is called and the DB query is executed in onPostResume () to acquire information for constructing the message list.

Then, a message list is constructed using the information obtained through the DB query (13d), and the configured message list is displayed on the screen of the mobile terminal 100 instead of the initial screen (13f).

According to the related art, the controller 180 performs a DB query in the onStart () method to acquire all information necessary for constructing a message list, and then displays an initial screen. After configuring the initial screen, the controller 180 constructs a message list using the information obtained through the DB query, and finally displays the message list on the screen.

As described above, conventionally, after the necessary information is acquired through the DB query, an initial screen is displayed, and a considerable time delay occurs until the initial screen is displayed. Also, as the initial screen display is delayed, the psychological time delay experienced by the user until the message application is executed also increases.

However, in the fifth embodiment of the present invention, as described above, the initial screen is displayed before obtaining the information necessary for the message configuration, thereby minimizing the time delay until the initial screen is displayed, To be reduced.
