         [0025]     The picture memory controller  41  receives picture information from the camera module  6  or an external memory, such as an FD memory and an IC memory card, inserted in the memory slot  5  and stores the picture information in the picture memory  7 . The picture information may be downloaded from a server connected to a network (not shown). The picture information from the server is received by the antenna  1  and demodulated at the modem unit  3 . The demodulated picture information is controlled by the controller  4  and stored in the picture memory  7 .  
         [0026]     The key input unit  8  comprises some keys for inputting a character and operation. One or more of the keys can be used for inputting a telephone number for making a call. One or more of the keys can be used for displaying a menu screen.  
         [0027]     Next, operation of the radio communication apparatus  10  having the above configuration will be described.  FIG. 2  is a flowchart showing an exemplary process for customizing a menu.  
         [0028]     At first, when the power of the radio communication apparatus  10  is turned on by pushing a power button (not shown), stand-by screen having the current time, power information, and radio information (RSSI) is displayed on the display  9  (step S 1 ). In this state, if a menu key of the key input unit  8  is pushed, an initial menu is displayed (Step S 2 ).  FIG. 3A  shows this state, where nine icons and guidance information are displayed on the display  9 . The guidance information is assigned to a specific key of the key input unit  8 . Preferably, the specific keys are located close to the corresponding guidance information.  
         [0029]     The specific key may be called soft key.  
         [0030]     An icon  51  of  FIG. 3A  is one of the nine icons and is made of a function name and a symbol image. Other icons are also made of a function name and a symbol image. Cursor  52  of  FIG. 3A  indicates that an icon is selectable and moves among icons under the operation of direction key (not shown) of the key input unit  8 .  
         [0031]      FIG. 3A  further shows two guidance information and each of the two guidance information indicates a function assigned to the specific key of the key input unit  8 . In this example, “My Menu  53 ” and “Options  54 ” are expressed as guidance information. My Menu  53  means customized menu and a customized menu (hereinafter “my menu”) is displayed when the specific key corresponding to My Menu  53  is pushed. Options  53  means edit menu and an edit menu is displayed when the specific key corresponding to Option  53  is pushed.  
         [0032]      FIG. 3B  shows an example of the edit menu. The edit menu has some edit items and, for example, six edit items are displayed on the display  9 .  
         [0033]     When the initial menu shown in  FIG. 3A  is displayed and the specific key corresponding to My Menu  53  is pushed, my menu, which is customized by a user, is displayed on the display  9  (Step S 3 ). The my menu is also has nine icons in this example and each icon, which indicates a specific function, is chosen by a user arbitrarily. Moreover, when the my menu is displayed, “Menu” is displayed as guidance information instead of “My Menu”. The menu displayed on the display  9  indicates that the initial menu will be displayed by pushing the specific key corresponding to the guidance information.  
         [0034]     When My Menu is displayed and the specific key corresponding to Options  54  is pushed (Step S 4 ), the edit menu of  FIG. 3B  is displayed in display  9  (Step S 5 ).  
         [0035]     The edit menu has at least four edit items, “Assign My Menu 31 ”, “Edit Title 32”, “Set Wallpaper  33 ”, and “Set Icon  34 ” as shown in  FIG. 3B .  
         [0036]     When the edit menu is displayed and Assign My Menu  31  is selected by the operation using key input unit  8  (Step S 6 ), function list (not shown) is displayed and user can edit which function is assigned to one icon on My Menu. The user ends editing by pushing a decision key of the key input unit  8  after the completion of the assignment (Step S 10 ).  
         [0037]     When Edit title  32  is selected by the operation using key input unit  8  (Step S 7 ), the user can edit the name of each icon. The user selects the icon, which is the subject for editing, and inputs a new name using the key input unit  8 . The user ends editing the name of the icon by pushing decision key (Step S 10 ).  
         [0038]     When Set Wallpaper  33  is selected by the operation using key input unit  8  (Step S 8 ), the user can select a picture displayed as wallpaper. By selecting the Set Wallpaper  33 , four pictures  55 ,  56 ,  57 , and  58  are displayed on display  9  as shown in  FIG. 3C . The user moves a cursor and sets the cursor on the desired picture to be displayed. If the user selects the desired picture or stops the selection, this process is ended by pushing the decision key (Step S 10 ).  
         [0039]     Besides the pictures stored beforehand in the picture memory  7 , the pictures read from external memory or captured by the camera  6  can be also used as wallpaper.  
         [0040]     If the picture  58  is selected and decision key is pushed, the selected picture is displayed as wallpaper in the display  9 . The selected picture will display not only stand-by screen but also the My Menu as shown in  FIG. 4A .  
         [0041]     In  FIG. 4A , icon  61 , which is one of nine icons, comprises a name of a function and outline. Other icons comprise the same.  
         [0042]     The feature of displaying menu with the wallpaper is that the icons comprise the function name and outline; thus, the entire picture is displayed in the display  9  without losing visibility.  
         [0043]     When Set Icon  34  is selected (Step S 9 ), the user can edit the name and the symbol image of the icon  61  displayed in the display  9 . As several thumbnail formed pictures or a list of the names of pictures are displayed in the display  9 , user can select the desired pictures and change the symbol images of the icons. For example, the symbol image of the icon  61  can be changed to different symbol image by moving cursor  62  on icon  62  and pushing the specific key corresponding to guidance  53  or set key (not shown).  
         [0044]     When the My Menu is displayed and the selection is executed other than the Options  54 , an application is started or the next menu is displayed in display  9  (Step S 11 ).  
         [0045]     Also, icons&#39; display locations can be switched. An example is shown in  FIG. 4B . The operation can be improved by locating the most used icon at where the cursor  62  is displayed.  
         [0046]     As shown in  FIG. 4C , the specific icon can be indicated by a picture even when the menu with the wallpaper is displayed. Also, as shown in  FIG. 4C , the selectable icon can by displayed in bigger size than other icons.  
         [0047]     In the above-mentioned example, the visibility of the wallpaper is kept by composing the icons with the name and the outline. Same effect can be obtained by comprising the icons with geometrical patterns and name as shown in  FIG. 5 .  
         [0048]      FIG. 5  shows an example of the icon comprising the geometrical patterns and a function name. In this example, there are several circles.  FIG. 5A  shows the state when the icon is not selectable and  FIG. 5B  shows the state when the icon is selectable. Thus, the differentiation of selectable icon and non-selectable icon is made by the change of geometrical patterns.  
         [0049]     The geometrical patterns is not limited to circle but can use triangles, squares, and hearts.  
         [0050]     In  FIG. 5 , the geometrical patterns and names are outlined by a dashed line. That is only to make it easy to see the composition of the icon. The dashed line is actually not displayed in the display  9 .  
         [0051]     As explained above, according to the embodiment of the invention, the utility and visibility of wallpaper can be maintained, and at the same time, the effectiveness of operation is improved by making icons transparent or enlarging icons.
