A microphone 78 is connected to the voice processing unit 7 so as to function as a transmitter when a telephone function is selected.
[0092]
Subsequently, an operation example of the mobile phone 401 as an embodiment according to the present invention will be described. FIGS. 13 and 14 are flowcharts showing processing examples (Nos. 1 and 2) in the mobile phone 401.
[0093]
In this example, the mobile phone 401 has a shape that is long in the vertical direction, and the liquid crystal display monitor 122 is also vertically long. The upper key K1, the left key K2, the lower key K3, and the right key K4 are arranged below the liquid crystal display monitor 122 as shown in FIG. 10, and basically, the left and right thumbs indicate the up, down, left, and right directions. The Further, it is assumed that the item selected by the up key K1, the left key K2, the down key K3, and the right key K4 is operated using the enter key 30A or 32A and the cancel key 30B or 32B.
[0094]
Of course, a case where the enter key 30A or 32A and the cancel key 30B or 32B are properly used according to the portrait display mode and landscape display mode will be described as an example. In the additional function mode, a game application process performed in the landscape display mode and a comic display process performed in the portrait display mode are prepared.
[0095]
Based on this assumption, the user presses the enter key 30A of the mobile phone 401 to turn on the power in step B1 of the flowchart of FIG. When the power is turned on, an initial screen is displayed on the liquid crystal display monitor 122 in step B2. The initial screen is configured on the premise of one-hand operation, and a one-hand operation application can be executed as it is. If the game application is supplied from the outside, this is displayed on the menu screen.
[0096]
Thereafter, the user selects a communication processing mode or an additional function mode in step B3 on this initial screen. If the additional function mode is selected here, the user proceeds to step B4 and selects either “comic” or “game”. The comic or game is selected by operating the mode setting switch 2 so that a portrait / landscape display setting signal S0 is output to the microcomputer 90 of the data processing unit 35 through the system bus 79. Here, when the user selects “comic”, the microcomputer 90 is set to the portrait display mode. The user holds the casing 1 with one hand, for example, the left hand.
[0097]
The microcomputer 90 generates an a contact selection signal S1 based on the portrait / landscape display setting signal S0, and this signal S1 is output to the key input switching circuit 9 through the system bus 79 and the interface 86. In the key input switching circuit 9, six switches SW1 to SW6 connect the contact point a to the neutral point N all at once based on the contact point selection signal S1. Thus, the direction related to the upper left lower right can be instructed as it is by the upper key K1, the left key K2, the lower key K3 and the right key K4.
[0098]
In step B5, the microcomputer 90 performs electronic comic image processing based on the portrait display mode. For example, the microcomputer 90 reads and processes the electronic comic information stored in the flash memory 33 and processes the game data D03 read from the memory card 203. The liquid crystal display monitor 122 is controlled to be displayed through the LCDC 88 based on the data processing, and an electronic comic video is displayed based on the video information D21.
[0099]
At this time, the user uses the up key K1, the left key K2, the down key K3, or the right key K4 to instruct the comic image displayed on the liquid crystal display monitor 122 to page forward. Thereafter, the microcomputer 90 checks whether either the enter key 30A or the cancel key 30B is pressed. If the cancel key 30B is pressed, the process returns to step B5. If the determination key 30A is pressed, the process proceeds to step B6, and the microcomputer 90 displays the information on the liquid crystal display monitor 122 by the operation information D3 based on the up key K1, the left key K2, the down key K3 or the right key K4 and the determination key 30A. Execute control.
[0100]
Thereafter, in step B6, it is checked whether or not the comic display process is finished. If the comic display process is not terminated, the process returns to step B5 and the display process is continued. When the comic display process is finished, the process proceeds to step B15. Therefore, the user can operate the cellular phone 401 with only the left hand, and can perform all operations such as page turning of comics without using the right hand.
[0101]
When the user selects “game” in step B4, the microcomputer 90 is set to the landscape display mode. Here, the user holds the casing 1 with both hands and operates with both hands. The microcomputer 90 generates the b contact selection signal S1 ′ based on the portrait / landscape display setting signal S0, and this signal S1 ′ is output to the key input switching circuit 9 through the system bus 79 and the interface 86. In the key input switching circuit 9, the six switches SW1 to SW6 connect the contact b to the neutral point N all at once based on the b contact selection signal S1 ′.
[0102]
Thereby, the up key K1, the left key K2, the down key K3, and the right key K4 in the portrait display mode can be cyclically shifted, for example, in the clockwise direction, and the direction related to the upper left lower right can be designated.
[0103]
Then, the microcomputer 90 checks whether the process proceeds to step B7 to execute (play) the game. When executing the game, at least the user operates the upper key K1, the left key K2, the lower key K3 and the right key K4 shown in FIG. The enter key 32A and the cancel key 32B are operated with the right hand. This is to deal with a game image that moves quickly.
[0104]
Thereafter, in step B8, the microcomputer 90 displays an image on the liquid crystal display monitor 122 according to the landscape display mode at a display position rotated by 90 ° with respect to the display position in the portrait display mode. In the image rotation processing, when the horizontal scanning direction in the portrait display mode is X, the vertical scanning direction is Y, the horizontal scanning direction in the landscape display mode is X ′, and the vertical scanning direction is Y ′, for example, LCDC88 Thus, the image data is converted by X ′ = − Y and Y ′ = X.
[0105]
In step B9, the user uses the up key K1, the left key K2, the down key K3, or the right key K4 to move the specific image in the vertical and horizontal directions in the image displayed on the liquid crystal display monitor 122. Instruct. Thereafter, the microcomputer 90 checks whether either the enter key 32A or the cancel key 32B is pressed in step B10.
[0106]
If the cancel key 32B is pressed, the process returns to step B9. If the enter key 32A is pressed, the process proceeds to step B11 where the microcomputer 90 displays the information on the liquid crystal display monitor 122 by the operation information D3 based on the up key K1, the left key K2, the down key K3 or the right key K4 and the enter key 32A. Execute control.
[0107]
Thereafter, the user instructs whether to move to Step B12 and end the “game”. If the “game” is not terminated, the process returns to step B9 to continue the data processing. When ending the “game”, the process proceeds to step B13, and the microcomputer 90 returns the landscape display mode to the portrait display mode. This is to execute display control in which the portrait display mode is the home position, and the mode switching process for returning to the user can be omitted. Thereafter, the process proceeds to step B15.
[0108]
When the communication processing mode is selected in step B3 described above, the process proceeds to step B14 to execute communication processing. In this process, when the number “0” to “9” key of the key array unit 8 is pressed with respect to the telephone number of the other party, the communication modem 22 is connected to a wireless base station, the Internet, a telephone line, a satellite line, or the like. Then, a normal telephone function is executed, or game information contents are downloaded using an existing communication infrastructure. A group of data strings received by the communication modem 22 is temporarily stored in the flash memory 33. Thereafter, the process proceeds to step B15.
[0109]
In step B15, it is checked whether or not to end the processing in the mobile phone 401. When these processes are terminated, the power-off information is detected, and the clock function and the like are left, and all the processes are terminated. If these processes are not terminated, the process returns to step B2 to display the initial screen. As a result, when the user ends the “game” and returns to the menu screen again, the mobile phone 401 returns to the one-handed operation state, and these states are repeated thereafter.
[0110]
As described above, according to the cellular phone 401 as an embodiment of the present invention, the up key K1, the left key K2, the down key K3, the right key K4, the enter keys 30A and 32A, and the cancel keys 30B and 32B can be placed vertically or horizontally. Since the left and right positional relationship is not changed, the display direction of the liquid crystal display monitor 122 and the up key K1 are displayed according to the application when an image is displayed according to the portrait display mode or the landscape display mode. By rotating the allocation direction of the left key K2, the down key K3, and the right key K4 by 90 °, either the vertical or horizontal direction can be used.
