Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication terminal device having at least one of a transmission function and a reception function, such as a mobile phone device and a portable information terminal device.
[0002]
[Prior art]
Conventionally, there are communication terminal devices such as a FAX phone and a TV phone that transmit a still image or a moving image, such as a mobile phone with a fax function disclosed in Japanese Utility Model Publication No. 6-62664.
[0003]
[Problems to be solved by the invention]
However, since such a conventional apparatus transmits image data itself, the amount of transmission data becomes large, and it is difficult to transmit in real time on current analog and digital lines. Specifically, even for image data of about VGA (640 × 480 dots, about 300,000 pixels), the amount of data is enormous in full color. Even if the number of simultaneous colors is reduced to 256 colors, one screen becomes data of 300 kbytes, and even if it is transmitted at a speed of 32 kbps, it takes nearly 10 seconds. Thus, since transmission in real time is impossible, communication could not be performed smoothly.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a communication terminal device that can more smoothly perform communication by document or voice.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the communication terminal device of the present invention, the first means for transmitting the code assigned to the image data as image selection data to the communication partner, and the communication partner transmits as the image selection data. A second means for reading out and displaying the image data to which the assigned code is stored from a storage means storing a plurality of types of image data, and a sensor, the sensor being a vibration sensor, an acceleration sensor, or an angular velocity. One of the sensors that detects whether the speaker is in a moving state or a stationary state at the time of a call , and the code that is transmitted as the image selection data depends on the detection result of the sensor. The image data represents a character indicating that the speaker is moving or stationary according to the assigned code. By that.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a mobile phone device according to a first embodiment of the present invention. The microphone 1 converts the input sound into an electrical signal. The electrical signal obtained by the microphone 1 is subjected to predetermined signal processing by the communication processing unit 2, modulated by the communication unit 3, and transmitted from the antenna 4. The signal received by the antenna 4 is demodulated by the communication unit 3, subjected to predetermined signal processing by the communication processing unit 2, converted to sound by the speaker 5, and output.
[0009]
The user can input a command to the device from the key input unit 6. The control unit 7-1 controls each unit so that the operation of the entire apparatus is in accordance with a command input from the key input unit 6. The liquid crystal display unit 8 performs a predetermined display under the control of the control unit 7-1.
[0010]
The storage unit 9 includes a rabbit basic pattern 1-0 as shown in FIG. 2, a cat basic pattern 2-0, a raccoon basic pattern 3-0, and a rabbit pleasure pattern 1 as shown in FIG. -1, a sadness pattern 1-2, a questionable pattern 1-3, an anger pattern 1-4, and the like. Different codes are assigned to these display characters. Note that the storage character 9 may be composed of an EEPROM or a RAM so that the display character to be stored can be rewritten.
[0011]
Then, under the control of the control unit 7-1, during a call, a preselected display character is read from the storage unit 9 and displayed on the liquid crystal display unit 8 as its own character, and assigned to the preselected display character. The transmitted code is transmitted as display character selection data.
[0012]
Further, the communication processing unit 2 extracts the code transmitted from the received signal as display character selection data from the received signal, and gives the code to the control unit 7-1. The control unit 7-1 The display character to which the code given from the communication processing unit 2 is assigned is read from the storage unit 9 and displayed on the liquid crystal display unit 8 as a partner character.
[0013]
The user can select the character type (rabbit, cat, raccoon dog, etc.) and character pattern (joy, sadness, doubt, anger, etc.) by performing predetermined key operations on the key input unit 6. It is like that.
[0014]
Next, FIG. 4 shows a block diagram of a mobile phone device according to the second embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the part same as the block diagram of the said 1st Embodiment, and description is abbreviate | omitted. The voice amplitude intensity measurement unit 10 measures the voice amplitude intensity input to the microphone 1 and gives the measurement result to the control unit 7-2. The speaker specifying unit 11 specifies a speaker from the voice pattern input to the microphone 1 and gives data indicating the specified speaker to the control unit 7-2.
[0015]
Then, under the control of the control unit 7-2, if the measurement result of the input voice amplitude strength in the voice amplitude strength measuring unit 10 exceeds the threshold during a call, a code transmitted as display character selection data is displayed for the speaker. The code assigned to the preselected pattern of the character corresponding to is switched to the code assigned to the basic pattern after a certain time.
[0016]
In addition, the control unit 7-2 reads a display character assigned a code to be transmitted as display character selection data to the communication partner from the storage unit 9 and displays it on the liquid crystal display unit 8 as its own character. At the same time, a display character assigned with a code given from the communication processing unit 2 (a code transmitted as display character selection data from the communication partner) is read from the storage unit 9 and is displayed on the liquid crystal display unit 8 as a partner character. Control to be displayed.
[0017]
Therefore, when the call amplitude intensity measurement result at the audio amplitude intensity measurement unit 10 exceeds the threshold during a call, the character displayed as the opponent character on the liquid crystal display unit 8 of the conversational device corresponds to the speaker. The character switches to a preselected pattern and returns to the basic pattern after a certain time.
[0018]
Note that the threshold value relating to the input voice amplitude intensity may be settable by the user. Further, the display character is controlled to switch to a preselected pattern only when the voice of a specific speaker is input, and the display is switched depending on whether or not the voice of the specific speaker is input. You may do it. Further, the display character selection data may not be transmitted, and for example, the character to be displayed may be switched independently on the reception side based on the amplitude intensity of the received voice.
[0019]
As described above, in each of the first and second embodiments, if a joy pattern is selected as the display character pattern, for example, the joy pattern character is displayed on the conversation person's device during a call. It is possible to communicate the intention of “welcome” to the interlocutor. Since the display character image itself is not transmitted, but the code assigned to the display character is transmitted, the amount of transmission data does not increase greatly, and real-time transmission is possible. Therefore, voice communication can be performed more smoothly. In addition, since the character of the pattern selected by the user, that is, the character of the pattern displayed on the user's device is also displayed on the user's device, it can be confirmed visually, which is convenient.
[0020]
Next, FIG. 5 shows a block diagram of a mobile phone device according to a third embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the part same as the block diagram of the said 1st Embodiment, and description is abbreviate | omitted. The control unit 7-3 can recognize the speaker state, specifically, the walking cycle of the speaker, based on the output of the sensor 12. As the sensor 12, for example, a vibration sensor, an acceleration sensor, an angular velocity sensor, or the like may be used.
[0021]
Then, under the control of the control unit 7-3, when the speaker is in a moving state during a call, for example, if the rabbit pleasure pattern is selected, the rabbit pleasure shown in FIG. The codes assigned to the state change characters 1-5 and 1-6 corresponding to the pattern are alternately transmitted as display character selection data according to the walking cycle of the speaker.
[0022]
When the speaker is in a stationary state, the character does not shift to the state change character. For example, when the rabbit pleasure pattern is selected, as shown in FIG. Display character selection data is transmitted so that the character 1-0 of the above pattern is always displayed on the liquid crystal display unit 8 of the apparatus of the conversation person.
[0023]
In addition, the control unit 7-3 reads a display character assigned a code to be transmitted as display character selection data to the communication partner from the storage unit 9 and displays it on the liquid crystal display unit 8 as its own character. At the same time, a display character assigned with a code given from the communication processing unit 2 (a code transmitted as display character selection data from the communication partner) is read from the storage unit 9 and is displayed on the liquid crystal display unit 8 as a partner character. Control to be displayed.
[0024]
Therefore, if the speaker is in a moving state during a call, for example, if the rabbit joy pattern is selected, the character displayed as the opponent character on the liquid crystal display unit 8 of the dialog device is shown in FIG. As shown in (a), the state change characters 1-5 and 1-6 corresponding to the joy pattern of the rabbit are alternately switched according to the speaker's walking cycle.
[0025]
As described above, in the third embodiment, the state of the speaker (moving or stationary, or the moving speed if moving) is reflected on the character displayed on the conversational device. Because you can, you will be able to communicate your status to the interlocutor. Since the display character image itself is not transmitted, but the code assigned to the display character is transmitted, the amount of transmission data does not increase greatly, and real-time transmission is possible. Therefore, voice communication can be performed more smoothly.
[0026]
Next, FIG. 7 shows a block diagram of a mobile phone device according to a fourth embodiment of the present invention. A transmission document is input to the microphone 1 by voice operation by the key input unit 6 or by voice. When the transmission document is inputted by voice, the voice recognition unit 13 converts the voice signal output from the microphone 1 into document data and gives it to the control unit 7-4. Then, the control unit 7-4 displays the input transmission document on the liquid crystal display unit 8, and in some cases, outputs the sound from the speaker 5 using the voice synthesis unit 14. As a result, the user can confirm the transmitted document.
[0027]
Then, under the control of the control unit 7-4, when a document is transmitted, a preselected voice pattern (a male voice, a female voice, a low voice, a high voice, Or a code assigned to data indicating whether it is a normal voice or the like) is used as voice pattern selection data, and a code assigned to a preselected display character is used as display character selection data. , Each attached to the header of the transmission document.
[0028]
In addition, when the document is received, a display character corresponding to a code attached as display character selection data to the header of the received data is read from the storage unit 9 in addition to the received document under the control of the control unit 7-4. The received document is displayed on the liquid crystal display unit 8 and, depending on the situation, the received document is reproduced by the voice corresponding to the code attached as the voice pattern selection data to the header of the received data using the voice synthesizer 14. Is output from.
[0029]
If the code assigned to the voice pattern is described in ASCII code, the voice pattern can be displayed as a document. When there is no data in the header, the received document is output with a standard voice selected in advance.
[0030]
In addition, the user switches whether to output the input document (transmission document) and the reception document by voice from the speaker 5 by performing a predetermined key operation with the key input unit 6. Can be done. Further, the user can select any kind of sound pattern by performing a predetermined key operation with the key input unit 6.
[0031]
As described above, in the fourth embodiment, on the receiving side, in addition to displaying the received document, the character selected on the transmitting side is displayed, and the received document is the voice selected on the transmitting side. It is easier to identify the sender. Since the display character image itself is not transmitted, but the code assigned to the display character is transmitted, the amount of transmission data does not increase greatly, and real-time transmission is possible. Therefore, it becomes possible to more smoothly communicate in documents by three or more parties.
[0032]
【The invention's effect】
As described above, according to the communication terminal device of the present invention, display characters (images) that change according to the situation can be added to communication by document or voice without significantly increasing the amount of transmission data. Therefore, real-time transmission is possible, and communication can be performed smoothly at almost the same level as communication performed with facial expressions and gestures.
