FIG. 3 is a flowchart showing display control processing executed in the mobile phone 1 when a plurality of programs are started in parallel. In the following description, a case where a movie playback program and a Web browser program are executed in parallel will be described as an example. As a premise of the description, it is assumed that when the movie playback mode is selected from the menu, the display control process shown in FIG. 3 is started.

  In the display control process shown in FIG. 3, a movie playback program is started in the control unit 8, and movie data (moving image data and sound data) to be played back is read from the program memory 13 and stored in the user memory 12. Then, the movie screen is displayed in full screen on the main display unit 190 by the display control of the control unit 8, and the movie is displayed on the movie screen based on the read movie data. In addition, sound output based on the sound data is performed from the speakers 161 and 162 with the display of the movie (step S1). Here, full screen display means that the display screen is not displayed in a reduced size but is displayed using the entire specified display area.

  At this time, the user memory 12 has a memory configuration as shown in FIG. That is, a cache memory area where movie data is stored in the user memory 12 and a heap memory area used by the movie playback program are formed.

FIG. 5A shows an example of a movie screen.
As shown in FIG. 5A, the display area of the main display unit 190 is divided into an area r1 for displaying a power supply state, a radio wave state, and the like and an area r2 for displaying based on each program. The movie screen d1 is displayed on the full screen using the entire area r2. On the movie screen d1, a URL d12 for accessing a website providing detailed information about the movie is displayed together with the movie d11.

  In addition, a menu icon k1 for performing a menu display operation, a stop icon k2 for performing a movie playback stop operation, and a jump icon k3 for instructing an operation to display the web screen of the URLd12 website are displayed. . These icons k1 to k3 are assigned to the shortcut key 177, the off-hook key 174, and the mode key 176, respectively. When the keys 177, 174, and 176 are operated, the control unit 8 receives the operation signal. It is recognized that the icons k1 to k3 have been operated.

  Note that while the Jump icon k3 is continuously operated, the Web screen downloaded from the Web site is continuously displayed. Therefore, the operator continues to press the mode key 176 on the movie screen d1 when accessing the Web site of the URL d12.

  In the cellular phone 1, based on the operation signal of the mode key 176, it is determined whether or not the Jump icon k3 has been operated in the control unit 8 (step S2), and if it is determined that it has been operated (step S2; Y). A Web browser program is started. At this time, as shown in FIG. 4B, a cache memory area for Web screen data and a heap memory area used by the Web browser are formed in an empty area of the user memory 12, and data of the movie playback program and the Web browser program are formed. The area will coexist.

  Then, the data of URLd12 processed by the movie playback program is processed as a URL to be accessed by the Web browser program. Specifically, the URL d12 data stored in the user memory d12 by the control unit 8 is stored in the web browser heap memory area. By executing the Web browser program, the control unit 8 reads the URL d12 data stored in the Web browser heap memory area, and the wireless unit 3 and the wireless processing unit 4 control access to the URL d12 Web site. . When Web screen data is acquired from the accessed Web site, the data is stored in the Web screen cache memory area of the user memory 12 (step S3).

  Next, a web screen is formed in the main display unit 190 by display control of the control unit 8 based on the web screen data stored in the user memory 12, and is superimposed on the movie screen d1 as shown in FIG. 5B. Then, the full screen is displayed (step S4). In FIG. 5 (b), the movie screen d1 and the Web screen d2 are not completely superimposed, and a part of the movie screen d1 on the back side is exposed. Since all the screens d1 and d2 are displayed on the full screen, they are completely superimposed.

  Further, a status icon d31 is displayed on the Web screen d2 by display control of the control unit 8. The status icon d31 is an index display indicating the current program start status. In the example shown in FIG. 5B, the Web screen d2 is displayed, but the movie playback program is also started, and the current movie playback is being performed. The status icon d31 indicates that it has been stopped.

  The operator continues to press the Jump key k3, that is, the mode key 176, while browsing the Web screen d2. When the user wants to return from the Web screen d2 to the original movie screen d1, the pressing operation of the mode key 176 is released.

  In the cellular phone 1, the controller 8 always monitors the pressed state of the mode key 176 based on the operation signal of the mode key 176 input from the key input unit 5, and the operation release of the mode key 176, that is, the Jump key When the operation release of k3 is detected (step S5; Y), the movie screen d1 that is hidden on the back of the web screen d2 as shown in FIG. The screen is switched to the front and displayed, and movie playback is resumed by executing the movie playback program (step S6). Further, a status icon d32 indicating that the Web browser program is being activated is displayed on the movie screen d1.

  In addition, since the Stop key k2, the Jump key k3, and the like are displayed on the movie screen d1, the operator operates the Jump key k3 when viewing the Web screen d2 again, and ends the movie playback. The stop key k2 is operated.

  In the mobile phone 1, when the operation of each key k1 to k3 is determined in the control unit 8 and it is determined that the Jump key k3 is operated (step S7; N), the process proceeds to step S4, and the movie screen d1 is displayed. The Web screen d2 that has not been displayed on the back side is switched and displayed on the forefront, and the control unit 8 shifts to processing by the Web browser program. On the other hand, when the Stop key k2 is operated (step S7; Y), the movie playback is finished and the movie screen d1 is not displayed, and this process is finished.

  As described above, according to the present embodiment, when the Jump key k3 is operated during the start of the movie playback program, the Web browser program for browsing the Web site of the URL d12 on the displayed movie screen d1 is started. Then, the Web screen d2 is superimposed on the movie screen d1 and displayed on the full screen. That is, function switching and display switching can be performed immediately following the operation of the operator. Therefore, the operator can immediately view a display based on another program while starting a certain program without ending the running program, and the operability is very good.

  In general, a mobile phone often has a small display screen area due to downsizing. Therefore, it is possible to make the display easier to view by performing full screen display and switching the screen than dividing the same display area and displaying a plurality of display screens simultaneously.

  In addition, since the display switching to the Web screen by the Web browser program is performed only while the operation of the Jump key is continued, the switching operation between the movie screen and the Web screen becomes easy.

  Further, since the status icons d31 and d32 are displayed to indicate which program based display screen is hidden on the back by the superimposition display, the operator can select which program by referring to the status icons d31 and d32. Can be easily grasped.

In addition, the said embodiment is a suitable example to which this invention is applied, Comprising: It is not limited to this.
For example, a case has been described in which a URL displayed during execution of a movie playback program is processed by a Web browser program and a Web site accessible by this URL is browsed. However, other programs can be applied. For example, the present invention can be applied to various situations, for example, when a map image is acquired and displayed from a URL included in the text of a received mail while the mail program is activated.

  In the above embodiment, the screen is switched by continuing the operation of the Jump key k3. However, switching to the Web screen d2 by one operation of the Jump key k3, switching to the movie screen d1 by the second operation, etc. Screen switching may be performed according to the number of operations. In this case, since it is not necessary to continue the operation of the Jump key k3, for example, after switching the screen from the movie screen d1 to the mail creation screen, the operator can freely perform other operations such as performing an input operation of the mail text. It is possible and convenient.
