An initial program for loading a simple program and data related to transmitted / received information such as e-mail are stored. The CPU 10 sets the operating environment of the mobile phone 1 by executing the above-described initial program when the mobile phone 1 is turned on. The storage unit 70 stores data and programs for realizing various functions related to the operation of the mobile phone 1.

  As shown in FIG. 3A, the main menu setting table 701 is a table that stores data related to icon images assigned to the various functions displayed on the display unit 20, and for the icon images for the various functions. “Display position” on the display unit 20, “Icon image address” indicating the storage location of the icon image data to be displayed, “Function name” indicating the name of the corresponding function, and “Function description” which is a brief description of the function Stores the “display count” for storing the number of times the explanation display based on the display unit 20 is displayed. The “display count” may be configured to store the number of times superimposed display based on a “function name” in a function display process described later.

  The display time setting table 702 selects the icon images displayed on the display unit 20 according to an instruction from the input unit 30 and displays the function description or the number of times that the function name is superimposed and displayed. Is a table for storing “time until the name is displayed” which is time information until the icon name is superimposed and displayed.

  The RAM 80 is a storage area for temporarily storing various programs executed by the CPU 10 and data related to the execution of these programs.

  Next, display processing related to function display at the time of standby screen display performed by the CPU 10 of the mobile phone 1 will be described with reference to the flowcharts shown in FIGS. FIG. 4 is a flowchart showing the function display process, and FIG. 5 is a flowchart showing the timer start process in the function display process.

  First, in a standby state in which a wallpaper image or the like is displayed on the display unit 20 to receive an operation instruction from the user, the CPU 10 makes a determination based on detection of a key operation in the input unit 30 (step S11), particularly key operation. If there is no key (step S11: N), the process is terminated as it is (maintaining the standby state), so that the standby state is maintained until a key operation is performed.

  When a key operation input is detected in step S11 (step S11: Y), a timer start process for starting a timer for measuring the time from the key operation input is started (step S12), and the main menu setting table 701 is started. Based on the above, a transition is made to a state in which various functions are displayed as icons on the display screen of the display unit 20 and a main menu that can be selectively activated is displayed (step S13).

  As shown in FIG. 6A, the display screen of the display unit 20 displaying the main menu in step S13 has a radio wave reception state, a remaining battery level, a connection state of optional devices such as a memory card, and a clock at the top of the screen. And the like, a main menu display area G12 at the center of the screen, a menu switch 301, a determination switch 304, and a submenu display area G13 for displaying functions when the display switch 302 is pressed.

  The main menu display area G12 is an area in which icon images assigned for various functions are displayed based on the main menu setting table 701, and a name for displaying the name of the icon image selected based on the “function name”. Display area G121, explanation display area G122 displaying a brief explanation of the function assigned to the selected icon image based on “function description”, and various function lists based on “display position” / “icon image address” Is formed from an icon display area G123. The selection icon G124 indicates that the icon is an icon selected from a list of icon images displayed in enlarged display. The selection icon G124 is selected as the center icon in the state where the main menu display is started from the standby state by the detection of the key operation, that is, the state immediately after the transition to step S13.

  After step S13, whether or not the cursor switch 303 is pressed, that is, an icon selection instruction performed by the user while referring to the selection icon G124 is detected (step S14), and the instruction is not particularly operated (step S14). : N) waits until the timer started in step S12 expires (a preset time is reached) (step S19).

  When the pressing operation of the cursor switch 303 is detected (step S14: Y), the timer count is reset and the timer is restarted by the timer start process similar to step S12 (step S15) and selected. The selected icon G124 is moved to the icon in the direction designated by the cursor switch 303 with respect to the icon, and the “function name” and “function description” for the newly selected icon are read from the main menu setting table 701. (Step S16), the display in the name display area G121 and the explanation display area G122 is replaced with that relating to the newly selected icon (Step S17), and the display relating to the newly selected selection icon G124 is replaced. Menu display It migrated to state (step S18), and is waiting until the pressing operation of the time-up or following a cursor switch 303 is performed (step S19).

  Next, when it is determined that the time is up, that is, when the pressing operation of the cursor switch 303 is not detected within a predetermined time (step S19: Y), the timer count is reset and the timer is restarted (step S20). All “function names” of the main menu icon displayed in the icon display area G123 are read from the main menu setting table 701 (step S21), and the display of the name display area G121 and the explanation display area G122 is selected. The function name corresponding to the icon image other than the selected icon image in the icon display area G123 is displayed as it is with respect to the icon as it is, and is superimposed and displayed in a semi-transparent state (step S22).

  As shown in FIG. 6B, the icon display area G123 in step S22 is displayed on each icon other than the selected icon G124 with the function name corresponding to the icon size corresponding to the icon size. Now it is displayed superimposed. In addition, it is preferable that the superimposed display of the function name is performed with the size of the character that can be identified by the icon image and the degree of semi-transparency so as not to impair the feeling of use of the user who is used to using only the icon image. .

  After step S22, the pressing operation of the cursor switch 303 is detected in the same manner as in step S14 (step S23). When no operation is input (step S23: N), it is determined that the time is up based on the timer started in step S20. The process waits to execute the processes in steps S22 and S23 until the process is completed (step S24), and the process ends. If a pressing operation is detected (step S23: Y), the process returns to the processing from step S15, the timer is reset by timer reset / timer start processing, and the icon corresponding to the operation instruction is selected. A transition is made to the menu display state (the state as shown in FIG. 6A).

  As described above, the mobile phone 1 displays a list of icon images symbolizing various functions on the display unit 20 based on the main menu setting table 701, and the next instruction input is performed from the cursor switch 303 from the list display. When the predetermined time has passed, the name for each icon image stored in the main menu setting table 701 is superimposed on the icon image and displayed in a semi-transparent state. In addition, the mobile phone 1 displays the name of the icon image selected by the cursor switch 303 and the description of the function corresponding to the icon image in the name display area G121 and the description display area G122.

  Therefore, by confirming the display screen of the display unit 20 on which the main menu is displayed, the user intuitively selects various functions of the mobile phone 1 through the icon image by confirming the display in the icon display area G123. Is possible. By confirming the display in the name display area G121 and the explanation display area G122, the details of the function corresponding to the selected icon image can be recognized, and the device can be handled quickly and accurately.

  Furthermore, even when the user cannot intuitively recall various functions from the icon image, the user can select a desired function based on the function name superimposed and displayed on the icon image after a predetermined time has elapsed. Moreover, since the superimposed display on the icon image is performed semi-transparently, it is possible to display the name of the function for an unfamiliar user without interfering with intuitive function recognition by the icon image of a skilled user. .

[Modification]
Next, as a modification, a configuration for setting the timer for the function display process described above based on the “display count” in the main menu setting table 701 will be described with reference to FIGS. 4 and 5. FIG. 5 is a flowchart showing details of the timer start process in the function display process. For simplification, the description of the same configuration is omitted, and only the “display count” count and timer setting of the main menu setting table 701 in the function display process will be described.

  The count of “display count” in the main menu setting table 701 is based on the “function description” in step S13 and step S17 when the display of the function description corresponding to the selected icon image is counted as “display count”. Is displayed in the explanation display area G122, and the “display count” corresponding to the selected icon image is incremented. In addition, when the superimposed display of the function name corresponding to the icon image is counted as “display count”, the “display count” corresponding to the icon image superimposed and displayed in step S22 in FIG.

  Then, in the timer start process in step S12, the CPU 10 reads “display count” of each icon image from the main menu setting table 701 as shown in FIG. 5 (step S121), and averages the read “display count”. Based on the value, the time until the name is displayed is read from the display time setting table 702 (step S122), a timer is set with the read time (step S123), and the timer is started (step S124).

  As described above, the mobile phone 1 is configured to set the function display processing timer based on the “display count” in the main menu setting table 701. It is possible to adjust the time until the name corresponding to the icon image is superimposed and displayed by the degree to which the user confirms the explanation corresponding to the icon image, and to display the function according to the number of times the user uses and the degree of proficiency Can do.

  In addition to the configuration in which one set time is read based on the average value, the set time of the timer in step S122 is read for each icon image, and the time up based on the set time of the timer in step S19 is read. A configuration in which the names are superimposed and displayed according to icon images having different display frequencies by performing the determination individually may be used. In this case, it is possible to perform display according to the proficiency level for each function of the user.

  Note that the description in the present embodiment shows an example of the present invention, and the present invention is not limited to this. The detailed configuration and detailed operation of the mobile phone 1 in the present embodiment can be appropriately changed without departing from the spirit of the present invention. For example, although a mobile phone has been described in the present embodiment, it may be a PDA (Personal Digital Assistant) or other information terminal, and does not limit the present invention.

  Further, the main menu display in the main menu display area G12 of the display unit 20 is arranged with a name display area G121 and an explanation display area G122 at the center of an annular icon display area G123 as shown in FIG. Other layouts may be used, such as arrangement of icon images arranged in a list form (not shown).

  The icon selection instruction by the input unit 30 is not limited to the cursor switch 303 but may be a numeric key, and is not particularly limited. Furthermore, the input unit 30 may be configured to include a dial-shaped instruction input key (not shown) as a suitable operation instruction when the main menu display has the layout shown in FIG.
