Description

  Embodiments described herein relate generally to an information processing apparatus.

  In an information processing apparatus, particularly a portable information processing apparatus such as a mobile communication apparatus with a small display screen, an application is generally assigned the entire display screen of a display unit for display. Therefore, when switching from the operation of one application to the operation of another application, or when the display on the display unit is switched by the operation of the same application, the displayed image transitions gradually and smoothly rather than switching instantaneously. (Hereinafter referred to as a transition) is a display switching that is easy for the user to understand.

  However, when switching images, there is a problem in that the displayed image is disturbed unless the management of the buffer for storing the image and the start of the transition process at the appropriate timing are not performed.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide an information processing apparatus that performs a transition process in which a displayed image is not disturbed.

  In order to achieve the above object, an information processing apparatus according to an embodiment of the present invention includes a buffer management unit and an image transition control unit that gradually changes an image from a first image to a second image, When the second application starts operation while displaying the image written by the first application in the first buffer on the display means, the image transition control means is stored in the first buffer. When the image is written to the copy buffer and the image is written by the second application to the second buffer allocated by the buffer management means, the image transition control means starts from the image stored in the copy buffer. While gradually changing the image to the image stored in the second buffer, the image is written into the first buffer and recorded in the first buffer. The image is characterized by displaying on the display means.

The copy buffer may be a storage area that is distinguished from the image buffer, or may be a part of the image buffer.

  The function of each part of the mobile communication apparatus configured as described above according to the embodiment of the present invention will be described with reference to FIG.

  The mobile communication network communication unit 12 obtains a high frequency signal from the radio signal received by the antenna 12 a from the base station, and transmits this high frequency signal to the mobile communication network control unit 13. Moreover, the high frequency signal transmitted from the mobile communication network control unit 13 is transmitted to the antenna 12a.

  The mobile communication network control unit 13 amplifies, converts and demodulates the high frequency signal from the mobile communication network communication unit 12, and transmits the digital voice signal obtained thereby to the call unit 14 and the control signal to the control unit 11, respectively. To do.

  The call unit 14 converts the digital audio signal transmitted from the mobile communication network control unit 13 into an analog audio signal, amplifies it, and sends it to the speaker 14a. Further, the analog audio signal transmitted from the microphone 14b is amplified, converted into a digital audio signal, and transmitted to the mobile communication network control unit 13.

  The display unit 15 is an organic EL display (Organic Electroluminescence Display) or LCD (Liquid Crystal Display) that is used to display a display prompting the user to operate, a display of contents operated by the user, a display of an operation state of the apparatus, or the like. The image data stored in the image memory (not shown) is displayed. Here, the image data is stored in an image memory by the control unit 11 and each unit of the apparatus, and includes letters, numbers, and icons. Hereinafter, unless necessary, the intervention of the image memory is omitted, and the control unit 11 and each unit of the apparatus are expressed as being displayed on the display unit 15. A part of the image is a soft key for identifying the operation, and the touch of the touch pad 16 to the position corresponding to the image is an input operation for causing a predetermined operation associated with the position. The icons and menu items constituting the menu are also soft keys.

  The touch pad 16 has a size substantially equal to the size of the display screen of the display unit 15, and a finger or a stylus pen (hereinafter referred to as a finger or a stylus pen is referred to as a finger or the like) is touched. Detect missing. Hereinafter, contact of the finger or the like with the touch pad 16 may be simply referred to as contact. The contact includes that the distance is less than a predetermined threshold. Then, when contact is detected, the touch pad 16 notifies the control unit 11 of the position where contact is detected. In this way, the display unit 15 and the touch pad 16 operate as a touch panel. Note that the touch pad 16 detects a contact by any method such as a resistance film method, a capacitance method, a method of detecting reflection of an electromagnetic wave by a finger or the like.

  The key input unit 17 includes a key switch that is pressed by a user of the apparatus. When the key is pressed, the key input unit 17 notifies the control unit 11 of the identifier of the key. The key includes a key for inputting limited instructions such as a power ON / OFF key, a volume adjustment key during a call, a call incoming / outgoing call, and a call end key.

  The application processing unit 18 includes various applications that start and end operations under the control of the control unit 11 (as described later, this control is a function of the application management function 11a). Examples of applications included in the application processing unit 18 are a standby processing unit, a call processing unit, an address book processing unit, an e-mail transmission / reception unit, and an e-mail browsing unit (all not shown). All of these applications are displayed on the display unit 15. Hereinafter, an application included in the application processing unit 18 is simply referred to as an application.

  The control of the control unit 11 that causes the application to operate and terminates the operation is mainly caused by the touch on the touch pad 16, for example, touching an icon indicating the application, to one or more menu items. By contact. In addition, it may be caused by a signal received by the mobile communication network control unit 13.

  The standby processing unit starts operation when the apparatus is turned on, and displays a standby image on the display unit 15. The standby image includes soft keys indicating applications other than the standby processing unit. When contact with the soft key is detected, the standby processing unit operates an application corresponding to the soft key via the control unit 11. Since the standby processing unit exists until the power of the apparatus is turned off, an application always operates in the apparatus.

  The call processing unit has a call function caused by a call operation, and when a predetermined contact is made, causes the display unit 15 to display a prompt for inputting a telephone number. Then, a telephone number is input according to the display. Alternatively, one telephone number is selected by a predetermined contact from the telephone numbers included in the address book data. Then, the mobile communication network control unit 13 is caused to make a call to the telephone number by a predetermined contact. When a call related to the call operation is connected, the call unit 14 is caused to perform a call operation.

  Further, the call processing unit has a call function due to the incoming signal, and the display unit 15 is notified of the reception of the incoming signal due to the incoming call signal received by the mobile communication network control unit 13, and the incoming call operation. The display prompting is displayed. When an incoming call operation is performed by a predetermined contact, a call related to the incoming signal is connected, and the call unit 14 is caused to perform a call operation.

  The address book processing unit adds the address book data to the address book file stored in the storage unit 19 according to the touch on the soft key, and corrects or deletes the address book data included in the address book file. These operations are performed interactively via the address book data displayed on the display unit 15. The address book data is information associated with a name, a telephone number, an e-mail address, and the like. When a predetermined contact is made with the displayed telephone number, the address book processing unit causes the call processing unit to make a call to the telephone number. Further, when a predetermined contact is made to the displayed e-mail address, the address book processing unit causes the e-mail transmitting / receiving unit to transmit an e-mail to the e-mail address.

  The e-mail transmission / reception unit has an e-mail transmission function and an e-mail reception function. First, as an e-mail transmission function, an e-mail transmission image is displayed on the display unit 15, and an e-mail address is input by predetermined contact, or One electronic mail address is selected by a predetermined contact from the electronic mail addresses included in the address book data. Then, the electronic mail input by the predetermined contact is stored in the storage unit 19 as a transmission mail together with the electronic mail address. The transmitted mail is transmitted to a mail server device (not shown) via the mobile communication network control unit 13.

  Further, the e-mail transmission / reception unit displays an e-mail incoming notification image on the display unit 15 based on the e-mail incoming signal received by the mobile communication network control unit 13 as an e-mail receiving function. The e-mail transmitted from is received via the mobile communication network control unit 13 and the e-mail is stored in the storage unit 19. The electronic mail browsing unit causes the display unit 15 to display the transmitted mail and the received mail stored in the storage unit 19 in accordance with predetermined contact.

  The application management function 11a operates the application and ends the operation. In addition, the history of operation start and end is stored. When the display on the display unit 15 is switched, the image transition function 11b makes a transition from an image displayed on the display unit 15 before switching to an image displayed on the display unit 15 after switching, that is, gradually. The image is changed and displayed on the display unit 15.

  The drawing management function 11c causes the display unit 15 to display the image by storing the image in the image buffer assigned to the image buffer management function 11d upon display by the application or the control unit 11.

  The image buffer management function 11d manages the allocation of image buffers, and makes the image transition function 11b perform a transition especially when notification of switching of images to be displayed is given. When a transition is performed, a plurality of image buffers are assigned to each function. Further, the image stored in the image buffer is displayed on the display unit 15 by copying it to the image memory.

  Here, the details of the transition image management table stored in the storage unit 19 will be described with reference to an example shown in FIG. This transition image management table is used by the image transition function 11b, and the drawing destination buffer 19a, the pre-transition image buffer 19b, and the post-transition image buffer 19c are associated with each other. The drawing destination buffer 19a is an image buffer that stores an image transitioned by the image transition function 11b. The pre-transition image buffer 19b is a buffer in which an image before switching when the image transition function 11b performs transition is stored. The post-transition image buffer 19c indicates a buffer in which an image after switching when the image transition function 11b performs transition is stored.

  FIG. 2A is a transition image management table when the image transition function 11b is not operating, and no information is stored. FIG. 2B shows the transition from the image stored in the “copy buffer” indicated by the pre-transition image buffer 19b to the image stored in the “image buffer 2” indicated by the post-transition image buffer 19c. The image created by the transition process is stored in the “image buffer 1” indicated by the drawing destination buffer 19a.

  Next, details of the buffer management table stored in the storage unit 19 will be described with reference to an example shown in FIG. This buffer management table is used by the image buffer management function 11d to appropriately allocate image buffers, and an image buffer 19d, a drawing request source 19e, a reference source 19f, and a display 19g are associated with each other.

  The image buffer 19 d is information for identifying an image buffer stored in the storage unit 19. In this embodiment, two image buffers, “image buffer 1” and “image buffer 2”, are provided. Therefore, the buffer management table includes two sets of information, that is, information that the image buffer 19d is “image buffer 1” and information that the image buffer 19d is “image buffer 2”.

  The drawing request source 19e has a function of storing an image in an image buffer identified by the image buffer 19d. The reference source 19f indicates a function of referring to an image stored in the image buffer identified by the image buffer 19d. The display 19g is “1” when the image stored in the image buffer identified by the image buffer 19d is copied to the image memory by the image buffer management function 11d, and as a result, the image is displayed by the display unit 15. When not displayed, the information is “0”. When displayed, the image stored in the image buffer is referred to by the image buffer management function 11d, but the image buffer management function 11d is not stored in the reference source 19f.

  FIG. 3A is an example of a buffer management table when the image transition function 11b is not operating. The “drawing management function” (drawing management function 11c) is associated with the image buffer 19d which is “image buffer 1”. Since the drawing request source 19e stores “1” in the display 19g, the image is stored in the “image buffer 1” by the drawing management function 11c, and the stored information is displayed on the display unit. 15 is displayed. Note that the image stored by the drawing management function 11c is an image displayed by the operation of the application.

  FIG. 3B is an example of a buffer management table when the image transition function 11b is operating, and corresponds to the transition image management table shown in FIG. That is, the “image transition function” (meaning the image transition function 11b) is stored in the drawing request source 19e and “1” is stored in the display 19g in association with the image buffer 19d which is “image buffer 1”. Thus, the image is stored in the “image buffer 1” by the image transition function 11b, and the stored information is displayed on the display unit 15.

  Further, since the “drawing management function” is stored in the drawing request source 19e and the “image transition function” is stored in the reference source 19f in association with the image buffer 19d which is the “image buffer 2,” the drawing management function 11c The image is stored in the “image buffer 2”, which indicates that the image is referenced by the image transition function 11b. As described above, the image stored by the drawing management function 11c is an image displayed by the operation of the application.

  The operation of the transition in the mobile communication device according to the embodiment of the present invention configured as described above will be described.

  First, an outline of the flow of image data when the application 1 is operating and the operation of the application 2 is not started, that is, the transition process is not performed will be described with reference to the data flow diagram shown in FIG. . At this time, since the image transition function 11b is not operating, the transition image management table shown in FIG. 2A is stored. The image output by the application 1 passes through the drawing management function 11c (A1), is stored in the image buffer 1 (A2), and is displayed on the display unit 15 (A3). In the data flow diagram, broken lines with arrows indicate the flow of data.

  The right to use the image buffer 1 and the image buffer 2 is controlled by the image buffer management function 11d. In the data flow diagram, a solid line without an arrow indicates the right to control or use the buffer. However, since the influence on the data flow is not necessarily large, the illustration and description are omitted as appropriate. This data flow corresponds to the buffer management table shown in FIG. 3A, and the image stored in the image buffer 1 indicated by the image buffer 19d by the drawing management function 11c indicated by the drawing request source 19e is displayed on the display unit 15. Is displayed by the display 19g.

  FIG. 5 shows a flowchart of the transition control operation performed by the application management function 11a in accordance with the operation of a new application. The application management function 11a starts a control operation when the running application 1 starts the application 2 (step S101), and performs a process of accepting the startup of the application 2 (step S102).

  The activation reception process will be described with reference to the data flow diagram shown in FIG. The application 1 requests the application management function 11a to start the application 2 (B1). In the data flow diagram, a solid line with an arrow indicates a control flow. The application management function 11a causes the image transition function 11b to prepare for the transition (B2). That is, the image transition function 11b requests the image buffer management function 11d to draw the image buffer 1, which is an image buffer used with the right to use the drawing management function 11c due to the operation of the application 1. Requesting that the original 19e be the image transition function 11b (B3).

  As a result, the image transition function 11b obtains the right to store in the image buffer 1 instead of the drawing management function 11c (B4). In response to giving this right, the image buffer management function 11d stores the drawing request source 19e whose image buffer 19d in the buffer management table is “image buffer 1” as the image transition function 11b.

  Further, the image transition function 11b uses the copy buffer (B5), and copies the image stored in the image buffer 1 to the copy buffer (B6). Here, the image stored in the image buffer 1 by copying is left as it is, and can be used for the subsequent transition processing. However, the present invention is not limited to this, and if there is no need to store an image in the image buffer 1 due to the type of transition, the function of image processing hardware, or the like, there is no need to copy. Further, the image buffer 1 may be regarded as a copy buffer and the copy buffer may be regarded as the image buffer 1.

  Furthermore, the image transition function 11b stores “image buffer 1” in the drawing destination buffer 19a of the transition image management table and “copy buffer” in the pre-transition image buffer 19b. The image displayed on the display unit 15 is the image continuously stored in the image buffer 1 (B7). FIG. 7 shows a transition image management table and a buffer management table when the activation acceptance process is completed.

  This activation acceptance process is performed prior to activation of the application 2, and is not performed after completion of the activation. Therefore, even if the startup process of the application 2 takes a long time, when the startup is completed and the creation of the image to be displayed on the display unit 15 by the application 2 is completed, the transition process is started immediately, and an unnecessary waiting time is Is not required.

  Next, the application management function 11a performs a transition preparation process (step S103). This transition preparation process will be described with reference to the data flow diagram shown in FIG. Upon reception of the notification of the end of the process related to the activation reception described above from the image transition function 11b (C1), the application management function 11a activates the application 2 (C2). In response to the activation, the application 2 notifies the application management function 11a of the activation completion, and the application management function 11a notifies the application 1 of the completion (C3). Subsequently, the application 2 requests the drawing management function 11c to display on the display unit 15 (C4), and the drawing management function 11c newly requests an image buffer from the image buffer management function 11d (C5).

  In response to this request, the image buffer management function 11d assigns the image buffer 2 to the drawing management function 11c (C6), and the image stored in the image buffer 2 is referred to by the image transition function 11b for the transition processing. (C7) is stored in the buffer management table. As a result, the buffer management table shown in FIG. 3B is stored.

  Furthermore, the image buffer management function 11d notifies the image transition function 11b that the image stored in the image buffer 2 is the image after the transition (C8). In response to this notification, the image transition function 11b stores the transition image management table shown in FIG. 2B in which the post-transition image buffer 19c is “image buffer 2”. The image displayed on the display unit 15 is the image continuously stored in the image buffer 1 (C9).

  Next, the application management function 11a performs a transition process (step S104). The transition process will be described with reference to the data flow diagram shown in FIG. The application 2 transmits the image displayed on the display unit 15 to the drawing management function 11c. After transmitting all the images displayed on the display unit 15, the application 2 requests the drawing management function 11c to display the image (D1). The drawing management function 11c stores the image in the image buffer 2 (D2), and further requests the image buffer management function 11d to display the image (D3).

  The image buffer management function 11d requests a transition process from the image transition function 11b (D4), and the image transition function 11b performs image buffering from the image stored in the copy buffer according to the transition image management table shown in FIG. Transition processing to the image stored in 2 is performed and stored in the image buffer 1 (D5), and the image stored in the image buffer 1 is displayed on the display unit 15 (D6).

  The application management function 11a notifies the application 1 of the start of transition processing (D7). The trigger for this notification is, for example, that the application 2 notifies the application management function 11a of the completion of the display image after requesting the drawing management function 11c to display the image at D1. Alternatively, when the D4 transition processing request is made, the image buffer management function 11d notifies the application management function 11a of the transition processing start. Furthermore, the image transition function 11b that has received the request notifies the application management function 11a of the start of the transition process.

  In this process, after all the images displayed on the display unit 15 by the application 2 are stored in the image buffer 2, the transition process by the image transition function 11b is performed. For this reason, the transition process is performed while the image by the application 2 is incomplete, and the display unit 15 is not disturbed.

  FIG. 10 shows an example of a change in display on the display unit 15 due to this transition, and the display changes from FIG. 10 (a) to FIG. 10 (d) over time. That is, FIG. 10A shows a display at the start of the transition process, and an image by the application 1 is displayed on the entire display screen of the display unit 15. FIG. 10B shows a display during the transition process after a short time has elapsed since the start of the transition process. The image by the application 2 is displayed with a narrow width on the right side of the display screen, and the image by the application 1 is displayed in the other parts. ing.

  FIG. 10C shows a display during the transition process after a long time has elapsed since the start of the transition process. The image by the application 2 is displayed on the right side of the display screen with a wide width, and the image by the application 1 is displayed in the other part. ing. FIG. 10D shows a display at the end of the transition process, and an image by the application 2 is displayed on the entire display screen of the display unit 15.

  Returning to the description of the control operation of the transition process of the application management function 11a with reference to the flowchart shown in FIG. Subsequently, the application management function 11a performs a transition end process (step S105), and ends this control operation (step S106). The transition end process in step S105 will be described with reference to the data flow diagram shown in FIG. When the transition process ends, the image transition function 11b deletes the information stored in the transition image management table and updates it as shown in FIG.

  The image transition function 11b further notifies the image buffer management function 11d that the transition process ends and the image stored in the image buffer 2 is displayed on the display unit 15 (E1), and the transition process ends. The application management function 11a is notified (E2). The application management function 11a notifies the application 1 of the end (E3). Here, the image buffer 2 is an image buffer indicated by the post-transition image buffer 19c of the transition image management table during the transition process.

  In accordance with this notification, the image buffer management function 11d updates and stores the buffer management table as shown in FIG. This buffer management table is different from the buffer management table shown in FIG. 3A in that the image buffer 2 is used instead of the image buffer 1, but the image transition function 11b does not operate and the drawing is not performed. It shows that an image by the management function 11c is displayed on the display unit 15. That is, thereafter, the image output by the application 2 passes through the drawing management function 11c (E4), is stored in the image buffer 2 (E5), and is displayed on the display unit 15 (E6).

  In the above description, as preparation for the transition processing in step S104, two-stage processing is performed, that is, processing in step S102 performed before the activation of the application 2 and processing in step S103 performed after the activation. . However, the present invention is not limited to this, and these two-stage processes may be appropriately combined for implementation.

  The transition processing described above is performed due to the application 1 starting the application 2, but the processing performed due to other operations is also the same. For example, the processing is performed due to the switching of the image displayed by the application, and is performed due to the switching of the image by the application 1 in order to restart the operation with the termination of the application 2. It is processing. Here, the application management function 11a has a history of the application operation start and end history stored in the application management function 11a, indicating that the application 1 has been displayed on the display unit 15 before the operation of the application 2 is started. Judgment by referring to.

  The application 1 relates to the activation of the application 2, from the application management function 11a to (1) completion of activation explained in C3 of FIG. 8, (2) start of transition processing explained in D7 of FIG. 9, and (3) FIG. The notification of the end of the transition process described in E3 is received three times. Which of these notifications is regarded as completion of activation of the application 2 and the operation of the application 2 is changed depends on the application 1.

  In other words, according to this embodiment, the application 1 loses the right to display on the display unit 15 at the stage where the activation of the application 2 is requested. However, for example, the application 1 may continue outputting the sound from the speaker 14a or the second speaker for music output until the notification of the end of the transition process is received. The volume of the output sound may be reduced from the reception of the transition processing start notification, and the sound output may be stopped by the reception of the transition processing end notification. Further, a predetermined sound may be output during the period from the reception of the transition process start notification to the reception of the transition process end notification. According to these operations, in addition to the transition performed on the display of the display unit 15, for example, by synchronizing and controlling output to other output means such as audio output, the device can be easily understood by the user. Can do.

  Next, transition processing (hereinafter referred to as recursive transition processing) performed during the transition processing will be described with reference to the data flow diagram shown in FIG. This is because, for example, when the above-described application 1 activates the application 2 and the transition process is performed, for example, an application included in the application processing unit 18 due to an interrupt generated when an incoming signal, particularly a call incoming signal is received, For example, it is a process performed when the call processing unit starts operation. Since the reception of the incoming signal is performed regardless of the intention or operation of the user of the apparatus, the user may not correctly recognize the reception. According to this recursive transition process, the user can easily recognize correctly. This recursive transition process is similar to the above-described transition process. Therefore, the description of common parts is omitted, or only a simple description is given.

  First, the activation acceptance process of the application 3 will be described. This process is similar to the activation acceptance process described with reference to the data flow diagram shown in FIG. Therefore, a description of similar operations is omitted, or only the main points are given. During the transition process, for example, when the image by the application 1 and the image by the application 2 shown in FIG. 10B are displayed on the display unit 15, an interrupt for starting the application 3 having a high priority is provided. When it occurs (F1), the application management function 11a temporarily stops the application 2 (F2), and makes the image transition function 11b prepare for the transition (F3). The image transition function 11b stops the transition process being processed, and copies the image stored in the image buffer 1 to the copy buffer (F4). The image displayed on the display unit 15 is the image continuously stored in the image buffer 1 (F5). The transition image management table and the buffer management table at this time are as shown in FIG. Subsequently, the transition preparation process described with reference to the data flow diagram shown in FIG. 8 is performed, the application 3 is activated (F6), the buffer management table shown in FIG. 3B, and FIG. The transition image management table shown is stored.

  Here, the application management function 11a can determine that the transition process is in progress from the start of the transition process described in D7 of FIG. 9 to the end of the transition process described in E3 of FIG. . The determination can also be made by storing “image transition function” in the reference source 19 f of the buffer management table.

  Next, a recursive transition process when the application 3 is activated will be described with reference to the data flow diagram shown in FIG. The application 3 transmits an image to be displayed on the display unit 15 to the drawing management function 11c, and after transmitting all the images to be displayed on the display unit 15, requests the drawing management function 11c to display the image (G1). The subsequent processing is the same as the transition processing described with reference to FIG.

  FIG. 15 shows an example of a change in display on the display unit 15 due to this recursive transition process, and the display changes from FIG. 15 (a) to FIG. 15 (d) over time. That is, FIG. 15A shows a display at the start of this recursive transition process, and this display is shown during the transition process from the image by the application 1 to the image by the application 2 shown in FIG. It is a display. FIG. 15B shows a display during the recursive transition process after a short time has elapsed since the start of the recursive transition process. A small image by the application 3 is displayed at the center of the display screen, and the other transitions include the above-described transition. The image being processed is displayed.

  FIG. 15C shows a display during the recursive transition process after a long time has elapsed since the start of the recursive transition process. The image by the application 3 is slightly larger in the center of the display screen, The image being transitioned is displayed. FIG. 15D shows a display at the end of the recursive transition process, and an image by the application 3 is displayed on the entire display screen of the display unit 15. According to such a change in display shown in FIG. 15, the user can easily know that the application 3 has been started by interruption during the transition from the image by the application 1 to the image by the application 2.

(Modification of recursive transition processing)
The recursive transition process described above is a process using the image buffer 1 and the image buffer 2, and is a recursive process and does not require more image buffers. However, the present invention is not limited to this, and processing using the image buffer 3 may be used. When the image buffer 3 is used, the image buffer management function 11d assigns the image buffer 3 to an image buffer request from the drawing management function 11c caused by a request from the application 3. Then, the image transition function 11b performs a transition process from the image stored in the copy buffer to the image stored in the image buffer 3.

  According to the processing using the image buffer 3, the image created by the application 2 when the application 3 is started is continuously stored in the image buffer 2 during the recursive transition processing. Therefore, for example, when the application 3 is terminated, the transition process when the application 1 starts the application 2 can be restarted from the image stored in the copy buffer and the image stored in the image buffer 2. it can.
