A telephone enabling a user to search a telephone directory using a simple and trouble-free operation. The telephone has a storage unit for storing names to be called and corresponding telephone numbers, and an operating unit including a plurality of numeric keys that are each assigned different characters. The telephone also includes a control unit. When a key press of at least the predetermined time is received by the operating unit, the control unit searches the storage unit for names that include a character assigned to the pressed numeric key, and displays the found names on a display unit. The user can switch the telephone to telephone directory mode and perform a keyword search simply by pressing a numeric key for at least the predetermined time.

Telephone for searching memory content using a simple user operation

A communication terminal apparatus that displays, on a display unit, character data included in e-mail messages, wherein the controlling unit () detects, among pieces of character data, pieces of data for delimiters such as spaces. When the controlling unit () has detected that delimiters of a same kind are arranged in a sequence longer than a predetermined upper limit, the controlling unit () instructs the main display unit (') that the excessive pieces of data for the delimiters beyond the upper limit should not be displayed. The main display unit (&#x2032;) does not display such pieces of data that are specified in the instruction.

Communication terminal apparatus and method for displaying characters on communication terminal apparatus

A communications terminal having an image shooting function allows a user to transmit a shot image as an e-mail attachment more easily and conveniently than in a conventional manner. Before being placed into an image shooting mode, the communications terminal first receives an e-mail address specified by the user as a destination of an image to be shot. Then, at a push of a shutter button in the image shooting mode, the communications terminal shoots an image to generate image data, automatically attaches the image data to an e-mail message, and transmits the e-mail message to the e-mail address specified by the user before the image shooting.

Communications terminal having image shooting function and program for the communications terminal

A communication terminal stores items which compose a hierarchical menu. The communication terminal displays items of one hierarchy on a display, and then displays lower level items, which correspond to an item which has been selected from among the displayed items by a user operation, without a display instruction operation by the user.

Communication terminal and display method

The folding communication terminal of the present invention is composed of a display device which is visible to the user when the folding communication terminal is in a folded state, and which is capable of multicolor display. The user knows by glancing at the illumination color, without reading characters displayed on the display device and without straining their eyes, whether a caller's telephone number is notified or not. Furthermore, the display is illuminated in a color which is specified and registered in advance in correspondence with the caller's telephone number. The user is thus able to know at a glance who a call is from. Furthermore, the display device is illuminated in a color distinguishing between whether there is notification information which is yet to be displayed or not. The user can judge whether it is necessary to check notification information with a glance at the illumination color.

Folding communication terminal and display control method therefor

A telephone that includes: a storage unit; a transmission/reception unitfor, when an incoming call is received, acquiring a caller's phone number corresponding to the incoming call; a counting unitfor measuring a time period between a start of a reception of the incoming call and a disconnection of the incoming call; and a one-ring-call judgment unitfor, if the measured time period is shorter than a predetermined time period, instructing a general control unitto store the acquired phone number into the storage unitas a target for a connection rejection so that if an incoming call is received from a caller having the stored phone number thereafter, a connection thereto is rejected.

Telephone for retrieving memory content through simple operation

A folding mobile communication device has a storage unit for storing at least one piece of call-destination information, each piece of call-destination information specifying a possible destination of a telephone call; a first display unit for displaying one piece of call-destination information in a position on a main body of the communication device that is exposed when the main body is in a folded state; and a call initiation unit for initiating, following the main body being put into an unfolded state, a telephone call to the destination specified by the piece of call-destination information being displayed.

A folding-type communication terminal includes a first display unit which is positioned so as to be visible when a main body of the communication terminal is in a folded state; a second display unit which is positioned so as to be concealed when the main body is in the folded state; a storage unit for storing at least one set of a piece of first information and a piece of second information, the piece of first information (i) having been generated based on information received accompanying incoming-communication, the incoming-communication being at least one of an unanswered incoming-call and incoming-mail, the incoming-mail being one of electronic mail and a character message and (ii) showing existence of the received information, and the second information showing details of the received information; a detection unit for detecting that the main body has been put into an unfolded state; a first display control unit for having the piece of first information displayed on the first display unit; and second display control unit for having the piece of second information displayed on the second display unit, when the detection unit detects that the main body has been put into the unfolded state while the piece of first information is being displayed on the first display unit, wherein the piece of second information belongs to a same set as the piece of first information.

Folding communication terminal having two displays

A baseband signal generator according to the present invention performs differential encoding and mapping processings for a digital baseband signal and limits bandwidths of the obtained symbol mapping data of an I phase and a Q phase by digital filters. Each digital filter includes a circuit for accumulating symbol mapping data corresponding to a plurality of symbol sections, a plurality of ROMs provided corresponding to the plurality of symbol sections for storing symbol data corresponding to a predetermined filter waveform, and an adder for adding symbol data output from there ROMs. The adder outputs a digital baseband signal whose bandwidth is limited, which signal is converted into an analog baseband signal by a D/A converter and supplied to an analog modulation unit.

Baseband signal generator for digital modulator

A digital DQPSK modulator according to the present: invention limits respective bands of symbol mapping data of I phase and Q phase obtained by applying differential encoding and mapping processings to a digital baseband signal, and multiplies the obtained data by the carrier signals by means of the digital filter. Such limiting of the bands and multiplication by the carrier signals are carried out by the digital filter in a time-divisionally multiplexed manner. The digital filter includes a circuit, for accumulating symbol mapping data for each of the I phase and the Q phase corresponding to a plurality of symbol sections, a plurality of ROMs corresponding to the plurality of symbol sections for storing a multiplication result of symbol data corresponding to a predetermined filter waveform and the carrier signal, and an adder for adding data output from these ROMs. The adder outputs a digital modulated signal which is, in turn, converted into an analog modulated signal by a D/A converter.
