BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings, taking a mobile phone as an example.
[0025]
FIG. 1 is a block diagram showing a main configuration of the mobile phone according to the present embodiment.
[0026]
The antenna 1 is connected to the transmission / reception unit 2, receives radio waves from the radio base station, and transmits radio waves to the radio base station. The transmission / reception unit 2 includes a transmission unit and a reception unit, and the transmission unit generates a high-frequency signal transmitted from the antenna 1. The receiving unit amplifies the high-frequency signal received by the antenna 1, converts the frequency, and outputs the result to the RF control unit 3 as a baseband signal.
[0027]
The RF control unit 3 includes a baseband unit and a wireless control unit. The baseband unit demodulates a baseband signal into a voice signal by using a codec unit in the baseband unit. The codec modulates the audio signal to generate a baseband signal. Further, the wireless control unit controls the frequency transmitted and received by the transmitting and receiving unit 2, the transmission and reception timing, and the output of the radio wave to be transmitted.
[0028]
Further, the control unit 4 is mainly configured by a CPU, and based on data stored in the RAM 5 and the ROM 6, each unit of the mobile phone such as the transmission / reception unit 2, the operation unit 7, the display interface 8, and the display unit 9. Control. The operation unit 7 receives input of characters and numbers, and an operation instruction to the mobile phone. The display interface 8 is a driver circuit that receives display data from the control unit 4 and drives the display unit 9. Also, an incoming call lamp (not shown) for notifying an incoming call to the mobile phone is provided.
[0029]
The display unit 9 is driven by the display interface 8 and includes a liquid crystal display panel that displays character information, an operation state of the mobile phone, and the like, and a backlight that illuminates the liquid crystal display panel. The display unit 9 includes a main display unit 9a and a sub display unit 9b. The main display unit 9a displays an operation menu, input items, and an echo back of a key input as character information transmitted by communication and information regarding an operation. The sub display unit 9b exclusively displays the state of the mobile phone (radio wave intensity, remaining battery level, time, etc.) or information related to the operation of the mobile phone, and functions currently assigned to function keys (function keys). And is provided in a partial display area of the main display 9a, which is smaller than the main display 9a. Note that the sub display unit 9b may be configured as a display panel different from the main display unit 9a. Further, if the main display unit 9a and the sub display unit 9b are provided at positions that can be visually recognized from the same direction, such as on substantially the same plane, the main display unit 9a and the sub display unit 9b may be on different surfaces ( For example, it is easier for the user to recognize the display of the incoming call during the operation than that provided at a position that cannot be visually recognized from the same direction such as the front and the back.
[0030]
Further, the mobile phone has a transmitting section (not shown) for converting an acoustic signal into an electric signal, and a receiving section (not shown) for converting an electric signal into an acoustic signal.
[0031]
FIG. 2 is a flowchart showing an operation at the time of waiting for an incoming call in the mobile phone according to the embodiment of the present invention.
[0032]
In the control unit, a main program that operates the mobile phone operates. In this main program, whether a key switch of the operation unit is operated is periodically scanned and monitored (S101). When it is detected that the setting switch has been operated ("YES" in S101), the mode shifts to a setting mode for executing additional functions such as function setting, memory dial registration, mail creation, ringtone setting, and display. A function screen for setting these additional functions (for example, a menu screen, a ring tone setting screen, a mail creation / browsing screen, and a telephone directory setting screen shown in FIG. 3A) is displayed on the section (S102). The setting mode indicates a mode in which the user is performing an operation for setting an additional function, and is a part of the function mode. Therefore, the function modes include a camera mode for capturing images from a camera (not shown), a browsing mode for stored images, a game mode, a calculator mode, and the like, in addition to the above-described setting modes.
[0033]
Then, when an incoming call to the mobile phone is detected during the setting mode (S103), caller information such as a caller number is extracted from the call signal transmitted from the base station. Then, the caller number is stored in the RAM 5, and the caller number relating to the incoming call is searched from the memory dial. If a telephone number corresponding to the memory dial is stored, the corresponding name together with the caller number is stored in the RAM 5. It is stored (S104).
[0034]
If the incoming call is an incoming mail, the sender mail address (or sender telephone number) and mail data (mail body) are stored in the RAM 5, and the sender mail address (or sender telephone number) relating to the incoming call is stored. Is retrieved from the memory dial, and if a sender mail address (or a sender telephone number) that matches the memory dial is stored, the corresponding name is stored in the RAM 5 together with the mail data (S104).
[0035]
Then, the incoming lamp flashes to notify the user of the incoming call, and the CPU determines whether the setting mode is continued (S105). The case where the setting mode is continued means that the application in the setting mode is running. In this case, the determination in step S105 is whether the application is terminated while receiving the incoming call and searching for the memory dial. It is for determining whether or not. If it is determined that the setting mode is continued ("Yes" in S105), the display position of information (incoming information) such as the caller's telephone number relating to the incoming call is determined by a method described later (S106). .
[0036]
As a display position of the incoming call information, there is a method of selecting a pictogram portion of the display screen. That is, as will be described later with reference to FIG. 3, a pictogram is provided at the top of the display screen to display the operating state (battery level, electric field strength, etc.) of the mobile phone in the form of a pictogram. The display position is determined so that the incoming call information is displayed on the screen. In addition, in order to emphasize the fact that there is an incoming call, it is possible to display an incoming call in the pictogram portion and also to use a part of the function screen to display a large character.
[0037]
There is also a method of selecting a position that does not hinder an operation (especially, data input) in a setting mode that is currently being executed as a display position of the incoming call information. That is, the cursor position during the input operation is determined, and the display position is determined so that the incoming call information is displayed in a portion far from the cursor position. This is because if displayed at a position close to the cursor position, the input operation is hindered. In addition to the cursor position during the input operation, the item to be input in the future (that is, the direction in which the cursor moves afterward) is determined, and the display position is displayed so that the incoming call information is displayed at a position different from the direction in which the cursor moves. Can also be determined. In this case, if the display is performed in the direction in which the cursor moves, the display is prevented from obstructing the input operation or the like as the input proceeds.
[0038]
When the display position of the incoming call information is determined, a display area is provided at this display position, and the caller number and the corresponding name stored in the RAM 5 in step S104 (in the case of mail reception, the sender mail address, the corresponding name, the mail Is displayed on the display unit 9.
[0039]
Then, it is detected whether or not the call key has been operated (S108). When the operation of the call key has been detected ("Yes" in S108), a call channel is set with the base station, and a transition is made to a call state. (S109).
[0040]
On the other hand, if the operation of the call key is not detected ("No" in S108), the setting mode is continued while the incoming call notification state displaying the caller number is maintained (S113).
[0041]
If it is determined in step S105 that the setting mode is to be released, a normal incoming call display for displaying the incoming call information on the entire display screen is performed (S111). Then, the process proceeds to a detection process (S114) for determining whether or not the call key has been operated.
[0042]
