(2 etc.) is cleared and a subroutine is initialized. Then, in step S12, keying is performed. In the key switch, whether or not each key of the key switch 5 and the numeric keypad 6 is operated is checked, and if there is an operated key, necessary processing corresponding to the switch is performed. For example, a process for repelling a prank call is performed.

Next, in step S14, the reception flag is turned off (cleared). The reception flag is turned on when a ringer tone signal is received from the other party.
Next, in step S16, the line voltage level of the NCU 72 is monitored to determine whether or not a ringer tone has been detected. When the ringer tone is detected, it means that a call is received from the other party. In this case, the reception flag is turned on in step S18, and then the process proceeds to step S20. On the other hand, if the ringer tone is not detected, the process jumps to step S18 and proceeds to step S20.

In step S20, the line voltage level of the NCU 72 is monitored to determine whether a call is in progress. If not, whether the video on / off switch 11 has been pressed. It is determined whether (turned on). If not pressed, step S
Return to 12 and repeat the same loop. If the video on / off switch 11 is pressed, step S24
Then, the procedure goes to step S3 to initialize the LCD display screen of the liquid crystal display unit 4. On the other hand, when a call is in progress, the process branches to step S26 to determine whether or not the reception flag is turned on, and when it is off, it means that the handset is lifted by itself, and step S24
Proceed to. If the reception flag is on, step S28
Move to.

If the process proceeds to step S24, the LCD screen of the liquid crystal display unit 4 is initialized and then the following step S24 is performed.
At 30, the moving process of the video RAM is performed. What is move processing?
The image compression / expansion circuit 51 reads the image stored in the video memory 54 in FIG. 2, for example, the captured image of the camera unit 3 or the video image input from the video terminal 53a of the ADC 53, and writes it in the video memory 55 as it is. is there. Next, a key scan is performed in step S32, and it is determined in step S34 whether the video on / off switch 11 has been pressed (turned on). If the button is not pressed and a call is in progress (step S36), the process returns to step S30 and the same loop is repeated.

On the other hand, if the video on / off switch 11 is pressed in step S34, the process branches to step S38 to determine whether or not a call is in progress. If no call is in progress, the process proceeds to step S40 to erase the LCD screen of the liquid crystal display unit 4, and proceeds to step S12 to return to the first key scan loop. If the result of determination in step S38 indicates that a call is in progress, the video on / off switch 11 is activated during the call.
Since is pressed, the process proceeds to step S42 of FIG. 7 to perform communication negotiation with the other party. In the negotiation, the communication environment is set to enable mutual communication with the other party.

Next, in step S44, the screen is initialized, and in step S46, the image compression / expansion circuit 51 is instructed to perform image compression / expansion processing. In addition,
In FIG. 7, the image compression / expansion / contraction processing is simply image compression / expansion processing, and so on. In addition, this step S4
At 6, the process of temporarily storing the image sent from the other party is performed. The stored partner image is used as an effective repelling method by transmitting it as a special image to the partner of the prank call.

Then, in step S48, the voice compression / expansion circuit 61 is instructed to perform compression / expansion processing for voice. Further, in this step S48, when a specific key is pressed, instead of processing the own voice from the handset 8, the voice stored in advance in the special voice memory circuit 202 together with the special image is played to the other party of the prank call. (For example, "Don't play fun!", "I'll call the police") is read, and it is instructed to perform the process of reproducing and transmitting. The process here is a process of compressing, combining with an image, and transmitting. As the voice, for example, in the above example, it is possible to select any one of “don't play fun!” And “call the police”, and a plurality of voices can also be played sequentially. It should be noted that if the special voice memory circuit 202 is stored in the form of voice data that has been compressed from the beginning, it is not necessary to compress it.

Then, in step S50, the communication process is controlled. After performing the key scan in step S52, it is determined in step S54 whether or not a call is in progress.
If in a call, the process returns to step S46 and repeats the same loop. If not in a call, the process proceeds to step S40 in FIG. 6 to erase the LCD screen of the liquid crystal display unit 4, and then step S1.
Go to 2 to return to the first key scan loop.

On the other hand, if the result of the determination in step S20 is that a call is in progress and the result of the determination in step S26 is that the reception flag is on, a call is received from the other party and the own monitor is displayed on the liquid crystal display unit 4 during the call. It is being displayed. At this time, key scanning is performed in the following step S28, and if the video on / off switch 11 is pressed in step S56, the negotiation of step S42 is performed. If the video on / off switch 11 is not pressed, the process proceeds to step S58 and it is determined whether or not a call is in progress. When the call is in progress, the process returns to step S28 and the same loop is repeated. When the call is not in progress, the call ends. The process proceeds to step S40 and the liquid crystal display unit 4
The LCD screen of is erased, and the process proceeds to step S12 to return to the first key scan loop.

Key Scan Processing FIG. 8 is a flowchart showing a subroutine of the key scan processing (step S52) in the main routine. If this subroutine is entered, step S100
To get the key information. The key information includes information from the keys of the key switch 5 and the ten key 6. Next, in step S102, it is determined whether or not there is a key operation, and if there is no key operation, the process returns to the main routine. In this case, if no key operation is performed, for example, only the image transmitted from the other party is displayed on the LC of the liquid crystal display unit 4.
It is displayed on the D screen.

On the other hand, if there is a key operation, step S10.
Go to step 4 to determine which key was operated. Then, steps S106 and S10 corresponding to the determination result.
8, step S110, step S112, step S
The process proceeds to either 114 or step S116.

For example, P in P (Picture in Picture)
When the key operation corresponding to is performed, it is determined and the process branches to step S108 to perform the P in P display process. In this case, the CPU 41 gives an instruction of P in P display to the image compression / expansion circuit 51, and finally L of the liquid crystal display unit 4 is displayed.
The parent-child screen is displayed on the CD 34. By the way, by default, your own image is the inset screen. After that, step S
In the loop of 100 → step S102 → return, P in
Although the P display is performed, when the key operation corresponding to the parent-child exchange is performed, it is judged and the process branches to step S106, and the CPU 41 issues an instruction of the parent-child exchange display to the image compression / expansion circuit 51, and the liquid crystal display unit. The LCD 34 of No. 4 displays a P in P parent-child screen in which parents and children are newly replaced.

When a key operation corresponding to another process is performed, it is judged and the process branches to any of steps S110 to S116 to perform another process. The other processes are the first repulsion key 15, the second repulsion key 16, the third
This is the case where either the repulsion key 17 or the portrait key 18 is operated. First, when the first repelling key 15 is operated, the process proceeds to step S110, and the special image is read from the special image memory circuit 201 and stored in the video memory 54. Since the face of the scary man is previously stored as image data in the special image memory circuit 201, the image data of the face of the scary man is read out and stored in the video memory 54.

Further, in step S118, a process for adding characters for repelling a prank call is performed. This processing is performed by pressing the character information key 19 (for example, when it is pressed, it is locked and lit). If the character information key 19 is not pressed, the addition of characters can be omitted. By the process of step S118, the character data related to the repulsion of the mischievous call is read from the special character memory circuit 203, and for example, the character data such as "Don't play fun!" Is added. After step S118, the process returns to the main routine. As a result, in the main routine, the image compression / expansion circuit 51 compresses / encodes the image data and the character data stored in the video memory 54. afterwards,
The image with the characters added is sent to the telephone line via the modem 71 and the NCU 72, and is sent to the other party.

Therefore, in addition to the scary man's face, characters such as "don't play fun!" And "I'll call the police" appear on the other party's videophone device, so it is better to stop the prank call. Therefore, the mischievous call in the case of the videophone device can be actively repelled.

A sound for repelling a mischievous call may be added to the transmitted image. This processing is performed by pressing the special voice information key 20 (for example, when pressed, it is locked and lit). If the special voice information key 20 is not pressed, voice addition can be omitted. In the process of adding a voice, the special voice memory circuit 202
From, voice data such as "Don't play fun!", "Call the police", etc. are read, and the image and voice are multiplexed,
It is sent to the telephone line via the modem 71 and the NCU 72, and sent to the other party. Therefore, in this case, not only the image but also the sound is added, so that the prank call can be repelled more effectively.

When the second repelling key 16 is operated, the process proceeds to step S112, the other party image sent through the telephone line is temporarily stored in the other party image memory circuit 205, and the one-screen data is sent to the other party. It is read from the image memory circuit 205 and stored in the video memory 54. Next, in step S118, similarly, a process of adding a character for repelling a prank call is performed. That is, the character data related to repelling a mischievous phone call is read from the special character memory circuit 203, and for example, "Don't play fun!" And "Call the police."
Is added to the image data of the partner image. After step S118, the process returns to the main routine. As a result, in the main routine, the image compression / expansion circuit 51 compresses / encodes the image data and the character data stored in the video memory 54. After that, the image with the added characters is sent to the telephone line via the modem 71 and the NCU 72, and is sent to the other party.

Therefore, in addition to one's own face, characters such as "Don't play fun!" And "I'll call the police" appear on the other party's videophone device that has played a trick, so it is better to stop the prank call. It becomes a judgment, and the mischievous telephone in the case of the videophone device can be actively repelled.

When the third repelling key 17 is operated, the process proceeds to step S114, and the process of deforming the self-image taken by the camera section 3 is performed. This processing is performed by the zoom processing circuit 204. As the zoom processing in this case, for example, the vertical and horizontal enlargement ratios of the self-image are changed, and the enlargement ratio is changed at a partial portion so that the image appears as a distorted mirror. Make it an image. The zoomed image is temporarily stored in the video memory 54. Next, in step S118, similarly, a process for adding characters for repelling a mischievous call is performed, and then the process returns to the main routine. As a result, the self-image transformed in the main routine and the characters for repelling the prank call are transmitted to the other party via the telephone line.

Therefore, on the other party's videophone device with the prank, characters such as "Don't play!" And "Call the police" are displayed in addition to this image that looks like a mirror distorted by zooming. Since it appears, it is decided that the prank call should be stopped, and the prank call in the case of the videophone device can be actively repelled. The self-image deformation process is not limited to the zoom magnification of the screen, and the eyes and the whiskers may be combined by, for example, an inversion, a partially corrected screen, or a montage method. In addition, a part of the other face may be combined appropriately, or other suitable processing may be performed. Specifically, for example, a process of uniformly increasing or reducing the enlargement ratio of a part (or all) of a screen having a linear or non-linear contour is performed, and for example, the head part is enlarged and the chin You may create the self-image which the part reduced. Further, mosaic screen processing may be performed to create a self-image that surprises the other party.

When the portrait key 18 is operated, the process proceeds to step S116, a self portrait is created, and the created portrait (including a plurality of portraits) is stored in the portrait memory circuit 20.
Store in 6. Then, at the stage of communicating with the other party, the portrait to be selected is read from the portrait memory circuit 206 and temporarily stored in the bio memory 54. The portrait creation process will be described in detail later in a subroutine. Next, in step S118, similarly, a process for adding characters for repelling a mischievous call is performed, and then the process returns to the main routine. As a result, in the main routine, the portrait image of itself and the characters for repelling the prank call are transmitted to the other party via the telephone line.

Therefore, in addition to the portrait image of the person on the other party's videophone device having the trick done, characters such as "Don't play fun!" And "Call the police" appear, so it is better to stop the prank call. It becomes a judgment, and the mischievous telephone in the case of the videophone device can be actively repelled. In addition, since it is only a portrait of oneself, there is an advantage that one's true face cannot be known to the other party.

When the second repelling key 16, the third repelling key 17 or the portrait key 18 is operated,
A sound for repelling a prank call may be added to each transmitted image. In the process of adding a voice, voice data such as “don't play fun!” And “call the police” is read from the special voice memory circuit 202, the image and the voice are multiplexed, and the data is transmitted via the modem 71 and the NCU 72. It is sent to the telephone line and sent to the other party. Therefore, in these cases as well, not only the image but also the sound is added, so that the prank call can be repelled more effectively.

Message Recording / Recording Processing FIG. 9 is a flow chart showing a message recording / recording processing routine. First, in step S120, it is determined whether or not the recording / recording button is turned on. The record / record button corresponds to the image capture switch 13, and this switch is used to instruct the message memory circuit 26 to store the image displayed on the liquid crystal display unit 4 as image data. Therefore, if the recording / recording button is not turned on in step S120, the process branches to NO in step S12.
Run normal mode with 2.

On the other hand, if the recording / recording button is turned on, the process proceeds to step S124 to determine whether or not it is online. If you are online, it will be judged that the call is established and you can not record / record your message,
The process branches to step S126 to execute online processing. Therefore, at this time, the process returns to the previous job (for example, call processing).

If it is not online in step S124, it means that a call is not in progress, and therefore the processing from step S128 is executed. In step S128, image compression is prepared. Also, in step S130, preparation for audio compression is performed. Then, in step S132, a start pilot signal (for example, a beeping sound or a voice signal "begin recording a message") is generated,
In step S134, the recording / recording process of oneself is started.
That is, the message may be spoken in front of the camera unit 3.

In the image recording / recording process, first, in the case of image processing, the trigger signal from the CPU 41 causes the image data of the camera section 3 (own screen) for one screen to be stored in the video memory 5.
Taken in 3. This data is the image compression / expansion circuit 5
It is compressed by 1 and temporarily stored in the buffer memory 52. The compressed image data is C
The message memory 26 is read out sequentially by the PU 41.
Written in. In this way, one screen of image data is stored in the message memory 26. This screen is used as an image in which the person's face is shown and responded to the other party. As the response screen, a plurality of images may be prepared instead of one screen, and the images may be switched appropriately.

On the other hand, in the case of voice processing, when the operator speaks into the microphone, the voice compression / expansion circuit 61 performs compression processing via the NCU 72 and the ADC 63, and temporarily stores it in the buffer memory 62. Then, the compressed voice data is sequentially read by the CPU 41 and written in the message memory 26. In this way, the voice data is stored in the message memory 26 and recorded. This voice is used as a response message for the other party. As a response message,
A plurality of messages may be prepared instead of one recording message, and the messages may be switched appropriately.

Next, in step S136, it is determined whether or not the recording / recording process is completed. If not completed, the process proceeds to step S138 and it is determined whether or not a timeout occurs.
This is to limit the length of the response message. If it has not timed out in step S138, the process returns to step S136, and if it has timed out, the process proceeds to step S140.

Also, when the recording / recording process is completed in step S136, the process proceeds to step S140. In step S140, an end pilot signal (for example, a beeping sound or a voice signal saying "the message ends") is generated and recorded / operated by the operator.
Notify that the recording is finished. Then, step S1
At 42, a recording / recording end process is performed. In this way
The process of recording / recording your message is performed.

In the above example, both the image and the voice are coded and recorded in the message memory 26, and the advantage such as the reduction of the memory capacity is obtained. However, the present invention is not limited to this. For example, the voice message is a voice signal. Record as it is,
The image may be recorded as an encoded signal.

Incoming Call Processing FIGS. 10 to 12 are flow charts showing an incoming call processing routine in the videophone device 1. First, in step S200, it is determined whether a ringer tone has been detected.
If the ringer tone is not detected, the process stands by in step S200. When a ringer tone is detected, step S20
At 2, it is determined whether the operator is off-hook. The operator off-hook is a state in which the operator off-hooks the handset (lifts the handset). When the operator lifts the handset, the process branches to step S204 to perform normal processing. Therefore, normal conversational communication with the other party is performed using the handset.

On the other hand, when the operator does not pick up the handset and remains off-hook, for example, when the operator is absent, the process proceeds to step S206 to determine whether or not the ringer tone is detected five times. If the ringer tone is not detected five times, the process returns to step S202, and if it is detected five times,
In step S208, it is determined whether or not the answering machine mode is set. When the answering machine mode setting switch 14 is pressed, the answering machine mode is set.

If not in the answering machine mode, step S202.
Return to. Therefore, at this time, the loop of step S202, step S206, and step S208 is repeated, and even if the ringer tone reaches five times or more, the operator does not pick up the handset, and there is no response from the called side.

On the other hand, if the answering machine mode is set in step S208, the process advances to step S210 to enter the off-hook state, and then the pre-message is transmitted. Therefore, the off-hook state brings the billing state. The pre-message is, for example, "I am out of the office right now. If you are a TV phone, turn on the video switch. If you are not, please wait as it is." This message is sent to the other party. Next, in step S212, the partner terminal is detected.

This is to detect the type of terminal in order to judge whether the partner terminal is a TV telephone or a normal telephone. Then, step S214
Then, it is determined whether or not the other party is a TV phone. The other party is TV
If it is a telephone call, the process proceeds to step S216 to set the videophone mode. On the other hand, when the other party is an ordinary telephone, the process proceeds to step S218 to set the call mode.

Then, move to FIG. A. When set to the videophone mode In step S220, sound / image reproduction processing is performed. That is, a process of reproducing image data (for example, face image data of the other party) and voice data (for example, response message data from the other party) sent from the other party through a general public line is performed. Specifically, the compressed image data and audio data sent from the other party via the public line are input to the modem 71 via the NCU 72. Then, this data is A /
It is D-converted, demodulated and sequentially transferred to the CPU 41. C
The PU 41 separates these data into image data and audio data, and the compressed image data is sequentially written in the buffer memory 52 and the compressed audio data is written in the buffer memory 62.

When the transmitted image is displayed on the liquid crystal display unit 4, the image compression / expansion circuit 51 then sequentially reads the image compression data written from the buffer memory 52, decompresses it, and writes it in the video memory 55. . afterwards,
The data written in the video memory 55 is D for each screen.
D / A converted by AC56 and sent to DD33, LCD34
To display. However, since it is in the answering machine mode this time, it is not actually displayed on the liquid crystal display unit 4, and the image and voice from the other party are recorded in the message memory 26 in the subsequent step S222.

When listening to the transmitted voice, next,
The voice compression / expansion circuit 61 sequentially reads the written voice compression data from the buffer memory 62, decompresses it, and outputs it to the DAC 64 at a constant rate. Next, the expanded analog audio signal is taken out from the TEL-side input / output terminal 73T via the NCU 72 and output by the speaker. In addition, similarly, this time, since it is the answering machine mode, the transmitted voice is not actually heard, and the subsequent step S22 is performed.
At 2, the voice from the other party is recorded in the message memory 26.

That is, after passing through step S220, the process proceeds to the following step S222, and the recording / recording process is started. As a result, the buffer memory 52
The image compressed data written in the message memory 26
The voice compression data written in the buffer memory 62 is also stored in the message memory 26. Next, in step S224, application processing (details will be described later in a subroutine) is performed. It performs one of several processes depending on the combination of dial tones of the telephone. At this time, when the message reproduction process is selected in the application process, the image and sound recorded in the message memory 26 are reproduced.

Next, in step S226, it is determined whether or not the other party has disconnected the telephone line. If not disconnected, the process returns to step S224, and if disconnected, the process proceeds to step S228 to perform the termination processing. In the termination processing, necessary processing due to disconnection of the line and standby processing for preparing for the next message recording / recording are performed again. In step S228, the incoming call process ends.

B. When the call mode is set In FIG. 12, sound reproduction processing is performed in step S250. That is, a process of reproducing only the voice data (for example, response message data from the other party) sent from the other party via a general public line is performed. In particular,
The compressed voice data sent from the other party via the public line is input to the modem 71 via the NCU 72. Then, this data is
The signals are / D converted, demodulated and sequentially transferred to the CPU 41.
The CPU 41 sequentially writes this audio data in the buffer memory 62.

Then, in step S252, the recording process is started. As a result, the voice compression data written in the buffer memory 62 as described above is stored in the message memory 26. Next, application processing (details will be described later in a subroutine) is performed in step S254.
Next, in step S256, it is determined whether or not the other party has disconnected the telephone line, and if not disconnected, step S25.
Returning to step 4, when disconnecting, the process proceeds to step S258 to perform end processing. In the termination processing, processing required for disconnection of the line and standby processing for preparing for the next message recording are performed again. In step S258, the incoming call process ends.

Application Processing FIG. 13 is a flowchart showing a subroutine of application processing. In the application processing, it is first determined in step S300 whether a DTMF tone signal has been detected. The DTMF tone signal is output, for example, when the other operator presses a push button on the telephone to perform a predetermined function operation. For example, [#]
This is a case where the button and the [1] button are pressed to perform recording / playback of a recording (that is, playback of a message). D
If no TMF tone signal is detected, step S30
Proceed to 2 to execute the next processing.

On the other hand, when the DTMF tone signal is detected,
Proceed to the processing step corresponding to the combination of the plurality of DTMF tone signals. For example, if the combination of DTMF tone signals is such that a message is reproduced, the process proceeds to step S304 and message reproduction processing is performed. Also,
If the combination of DTMF tone signals is such that the message is updated, the process proceeds to step S306 to perform the message update process. The processing by combining the DTMF tone signals is not limited to the example of FIG. 13, and other processing may be used.
After the corresponding processing, the process returns to step S330 and the same loop is repeated.

Portrait Drawing Processing FIG. 14 is a flowchart showing a subroutine of portrait drawing processing. The portrait creation process is performed when communication is not being performed via a videophone. In the portrait creation process, first, in step S400, a basic pattern for creating a portrait is displayed on the screen. There are various basic patterns as shown in FIG. In FIG. 15, for example, the vertical axis is 1. Face contour, 2. Hairstyle, 3. A plurality of parts are prepared corresponding to the basic elements that make up the face, such as the eyes, and a plurality of figures (parts) corresponding to each of the basic elements are prepared on the horizontal axis. For example, 1. The parts showing the lower half of the face corresponding to the contour of the face are [01], [0
2], [03], [04], and so on. The basic pattern is not limited to the one specifically shown in FIG. 15, and many others (eg, nose, ears, eyebrows, etc.)
May be prepared.

Then, a part is selected from the basic patterns displayed in step S402. For example, 1. Regarding the outline of the face, the parts [01], 2. As for the hairstyle, parts [02], 3. For the eyes, select each part such as part [03]. As a result, a caricature is displayed on the screen by each part forming the face.

Next, in step S404, the portrait is corrected. In the correction process, for example, the side of the face is expanded / contracted, the length of the face is expanded / contracted, or the position of each part is shifted. This changes the portrait and can be modified in various ways. Next, in step S406, it is determined whether the correction result is OK, and OK
If not, the process returns to step S402 to repeat the same processing, and if OK, the process proceeds to step S408 to store and register the self-portrait created in the portrait memory circuit 206. In this way, a self-portrait can be created and one or more portraits can be registered. In addition,
The creation of the portrait is not limited to the above example, but may be performed by graphic processing, for example.

The present invention is not limited to the above embodiment, but can be carried out in the following various modified modes. (A) The special image that repels a prank call is not limited to the image data of a scary man's face, but may be, for example, an animation or a portrait. (B) In the above embodiment, the special image is used to repel a prank call, but if an animation or a portrait is adopted as the special image, the present device can be used for playing between children, for example.

(C) The special image for repelling a prank call is stored as data before compression, but it may be stored as an encoded signal, for example. Further, the character information and voice information that are unrelated to the mischievous call repulsion are not limited to the example of being stored as a signal before being encoded, but may be stored as an encoded signal, for example. By doing so, the memory capacity can be reduced.

[0111]

According to the present invention, by operating the specific key, the special image is transmitted to the other party of the mischievous telephone, and if necessary, the character information or the special voice information is transmitted together with the special image. Therefore, a scary man's face etc. appears on the other party's videophone device that set up mischief,
It is decided that it is better to stop the prank call, and the prank call in the case of the videophone device can be actively repelled. Therefore, as a result, a prank call can be effectively prevented. In addition to the special image, the sent partner image can be sent as a special image, the self-image can be transformed and sent to the other party, or a portrait can be sent together with each of these images. By transmitting character information or special voice information, it is possible to actively repel a prank call with various images, and as a result, it is possible to effectively prevent a prank call.
