In a network electronic mail by a personal computer, it is possible to attach image data to character data and send it. However, application software for expanding the image on the personal computer on the terminal side that receives the image data is required. Separately required.

[0005]

From the above point of view, transmitting an image by some kind of communication system is simpler than an information communication device which requires a complicated operation such as making full use of special application software. It is difficult to realize with a portable device having a transmission function, such as a paging receiver also having a transmission function, and it cannot be easily used.

[0006] By the way, when an image is transmitted, a copy of the image can be distributed indefinitely at present unless the transmitting person is aware of it, which may cause a problem in terms of copyright and the like.

As one means for solving this problem,
Although it is possible to attach a seal such as information indicating the sender to the image to be distributed, the seal attached to the image is especially important for images with a small pixel configuration of the original image and low precision. However, the resolution is also low, and it is undeniable that it will be slightly inferior to the image of the original seal as the target of browsing.

The present invention has been made in view of the above situation, and an object of the present invention is to enable the transmission of image data using an existing communication network, while prohibiting copying of data to be transmitted. When

Here, the corresponding file name is “info xx” and the image management address is “0”.
I remember 02 '.

The RAM 10 has a user information memory area UD, a telephone directory data memory area TD, as shown in FIG.
It has an individual calling message memory area PMD, an information providing service data memory area IMD, an image data management memory area IMM, and an image data storage area IMGD.

The user information memory area UD stores the name of the user who owns this paging receiver and the calling number in association with each other as shown in FIG. 4, for example.

As shown in FIG. 5, the telephone directory data memory area TD has a registration number, a name, a telephone (call) number, an address, and a paging type flag F2 indicating whether or not the paging type is possible with an image. A plurality of sets are stored as a set.

Information providing service data memory area IM
As shown in FIG. 6, D stores a message number, an incoming call address, the contents of information to be displayed as a headline, a corresponding image management address, and an incoming call date and time as a set to sequentially receive incoming calls.

In the image data management memory area IMM, as shown in FIG. 7, the image management address and the capacity of the image, the copy prohibition flag F3 indicating whether or not the image prohibits copying, and the image is copied. The copy flag F4 indicating whether or not it is a file, the file name of the image, and the bitmap image obtained by simplifying the image data of the binary monochrome image are stored in association with each other.

The image data storage area IMGD stores the original image data which is not simplified in association with the file name of the image.

As shown in FIG. 8, the ROM 11 has a program ROM memory area 111, a character generator (CG) memory area 112, a JIS8 code conversion table 113, and an 8-bit / dot pattern conversion table 1.
14, a shift JIS area table 115, and a free word table 116.

The program ROM memory area 111 is
It mainly stores an operation program of the CPU 4, a display control program, and other various programs.

Character generator memory area 11
2 stores the dot pattern data of full-width characters displayed with 12 dots in the horizontal direction and 13 dots in the vertical direction.

The JIS8 code conversion table 113 is a table for converting bit data sequentially read in 8-bit units from a bit data string received by the IP paging service into a corresponding character as shown in FIG. Yes, the conversion designation information is the upper 4 bits (0 to F)
And the lower 4 bits (0 to F) are arranged in a matrix to store conversion designation information of characters to be generated by the character generator 112. Here, for example, if the bit data is "41", the character "A" is designated for conversion, and if the bit data is "B1", the character "A" is designated for conversion.

This JIS8 code conversion table 113
Is originally 16 (upper 4 bits) x 16 (lower 4 bits)
= 256 characters can be specified, but IP
In the paging system, "8
Regarding the 64 conversion designation areas of "0" to "9F" and "E0" to "FF", JIS X 0208 (Kanji code table)
Is not used to instruct conversion to so-called "shift JIS" code in which 2-byte data of the above is replaced with data designating the same, and "00" to "2F", "7"
34 conversion designation areas of "F" and "A0" are undefined. Therefore, the IP paging system does not use these 98 areas.

Therefore, in the IP paging system, "20" to "7E", "A1" in the JIS8 code conversion table 113 excluding the above area are excluded.
Only 158 conversion designated areas of "DF" are valid.

In this paging receiver, however, 128 conversion designation areas "20" to "6E" and "B1" to "DF" in the 158 conversion designation areas are used as image data in the image pattern. Shall be used by assigning to.

The shift JIS area table 115 is "80" to "9F" in the table described in FIG.
It is assumed to be a table having 64 conversion designation areas of "E0" to "FF".

8-bit / dot pattern conversion table 1
Reference numeral 14 is for converting 8-bit data as image data into 7-dot dot pattern data as shown in FIG. 10, and the above-mentioned “80” to “9F” and “E” are used.
A dot pattern of 7 dots of each dot "1""0" is generated corresponding to 64 conversion designation area bit data of "0" to "FF".

That is, the white dot portion shown as a 7-dot pattern indicates "0" (OFF) in bit data, and the black dot portion indicates "1" (ON) in bit data.

For example, the JIS8 code is "20" (00
100000) is specified, it is converted into a 7-dot dot pattern of 7 bits (0000000) and used as part of the image data displayed by the display driver 6.

The free word table 116 is a conversion table for creating a free word message by combining two digits of dial data "1" to "0" as shown in FIG. 11, and for example, dial data "23". It is assumed that the hiragana "ku" can be displayed by transmitting.

The transmission data memory 12 sequentially inputs and stores data to be transmitted.

When the message is received by the individual calling service, the notification driver 13 drives the LED 14 to blink according to the preset notification contents, and the speaker 15
To make a sound.

The transmission buffer 16 is a DTMF (Dual Ton) based on the transmission data created by the CPU 4.
e Multi Frequency: dial tone)
Data (numerical data, etc.) that can be converted into a signal is sequentially buffer-stored and sent to the D / A converter 27.
The conversion unit 17 converts the data into an analog tone signal (DTMF signal), which is amplified by the amplifier 18 and then output to the speaker 19 so that the preset DTMF is a combination of two audio frequency signals. The signal is output continuously.

The connector 20 is for taking in image data attached to the message at the time of transmitting the message. For example, when the connector 20 is connected to a personal computer prepared by a service provider, the image data is taken in for a fee or free of charge. The image data storage area IMGD can be stored and set.

The infrared transmitter / receiver 21 is, for example, IrD.
A (Infrared Data Associate)
Infrared communication is performed with other electronic devices according to the rule n), and an image is captured in the same manner as the connector 20.

Next, the operation of the above embodiment will be described.

FIGS. 12 to 14 show the operation processing contents in the message transmission mode for creating and transmitting a message. Initially, the menu screen is displayed (step S01), and one of the items in the menu is displayed. It is detected that the new creation of the message which is the item is selected and operated (step S02), and if the reading of the already created message is selected and operated (step S5).
By repeatedly executing the process 1), these detections are waited.

When it is determined in step S02 that the selection operation for creating a new message is detected, the process of actually inputting the new message is sequentially executed (step S03), and the message is input. It waits for the detection of the operation for ending (step S04).

When it is determined in step S51 that the selection operation for reading the already created message is detected, the transmission message is selected and read from the individual calling message memory area PMD of the RAM 10, While sequentially performing the editing process as needed (step S52), the process waits until an operation for ending the process is detected (step S53).

If it is determined in step S04 that the operation for ending the message input is detected, or if it is determined in step S53 that the operation for ending the processing for the message is detected, then the message Whether or not an image is attached corresponding to the address data for the information providing service, that is, in the stored contents of the ID-ROM 9 in FIG. 2, the frame number '87 in which the corresponding image flag F1 is set to "1" It is determined whether or not the transmission is based on the address data corresponding to'or frame number '103' (step S05).

If it is determined that an image is attached, a guide message prompting the user to select whether to attach image data to the created message is displayed on the display unit 7 (step S06). ), It is determined whether or not an instruction input to attach an image has been made (step S0).
7).

When it is judged that an instruction input to attach an image is made, next, referring to the image data management memory area IMM of the RAM 10 shown in FIG. 7, whether or not a plurality of image data are stored and set, That is, it is determined whether it is necessary to select image data (step S0).
8).

When a plurality of image data are not stored in the image data management memory area IMM and only one image data is stored and set, there is no choice, so that one image data is used. Although the following image data selection processing is omitted, when it is determined that a plurality of image data is stored and set, a bit obtained by simplifying the image data stored and set in the image data management memory area IMM is used. While displaying all of the map images and sequentially displaying them on the display unit 7 while displaying a guide message for prompting the user to select which image to attach on the display unit 7 together with the image data (step S09), an instruction input for selecting an image is input. Wait for detection (step S
The process of 10) is repeatedly executed, and the process proceeds to the next when the detection is made.

That is, when the image data selection is completed,
Then, the copy inhibition flag F3 in the image data management memory area IMM corresponding to the selected image data is set to "1".
Is set (step S1)
1).

Here, "1" is set in the copy prohibition flag F3.
When is set, it is prohibited to copy the image data and attach it to the created message and send it. Therefore, a guide message indicating that the image data cannot be copied is displayed on the display unit 7. After that (step S34), the process returns to step S05 to determine whether or not to attach the image data.

If it is determined in step S11 that "1" is not set in the copy prohibition flag F3, then the copy flag in the image data management memory area IMM corresponding to the selected image data is also selected. It is determined whether or not "1" is set in F4 (step S12).

Here, if "1" is set in the copy flag F4, it is prohibited to copy the image data as it is and attach it to the created message to send. , A character pattern based on the user name of the user information memory area UD shown in FIG. 4 is added to the selected image data, and the image data is decomposed into 7-dot units and converted into JIS8 code. Send data memory 1 with created message
Set to 2 (step S33).

In FIG. 15, when the bitmap image stored in association with the image management address "001" of the image data management memory area IMM is selected as the image data to be attached, the image file name "HYA" is selected.
KKA. BMP ”is an example of the image data itself of vertical 56 × horizontal 90 dots read from the image data storage area IMGD, and here the entire image is divided into blocks of vertical 4 × horizontal 9 and shown by the arrow on the right side of the figure It is assumed that each block is processed in the same order as the raster scan in the television image.

FIG. 16 exemplifies a dot pattern of a block divided into vertical 14 × horizontal 10 dots. Here, the block “PICT2” shown in FIG. 15 is used.
Shows the contents of the dot pattern.

The dot pattern is further divided into 7 dots in the same order as the raster scan in the television image so that the block "PICT2" is <1> to <20> as shown in FIG. The dot pattern of each dot row can be converted into a row of JIS8 code as shown in FIG. 18 by referring to the 8-bit / dot pattern conversion table 114 of the ROM 11 shown in FIG. can do.

Therefore, such a JIS8 code string is sent together with the created message in the transmission data memory 12
Will be set to.

If "1" is not set in the copy flag F4 of the image data selected in step S12, the image data is copied as it is and attached to the created message and transmitted. Since it is permitted to do so, the selected image data is directly decomposed into 7-dot units, converted into JIS8 code, and set in the transmission data memory 12 together with the created message (step S13).

In this way, when the setting of the data to be transmitted in the transmission data memory 12 in step S33 or S13 is completed, a guide message prompting the user to input an instruction for designating the transmission destination is then displayed on the display section 7. In this state (step S14), it is detected that the destination is newly input, or that the telephone number already stored in the telephone directory data memory area TD of the RAM 10 is selected as the destination. Is repeatedly waited for (steps S15 and S28).

When it is determined in step S15 that a new destination is detected, a guide message prompting the user to input data to the telephone directory data memory area TD including at least the individual calling number and paging type is displayed on the display unit 7. Is displayed (step S16), and thereafter, while sequentially accepting the input operation from the key input unit 8 (step S17), the processing of waiting for the completion of the input to be detected (step S18) is repeated.

When it is determined in step S18 that the end of input has been detected, the content of the flag F2 indicating whether or not image data can be received corresponding to the paging type is stored in the telephone directory data memory area TD. The setting is input at the corresponding position (step S19).

If it is determined in step S28 that the telephone number already stored in the telephone directory data memory area TD is selected as the destination, it is registered in the telephone directory data memory area TD. In the state where a list of the names that are displayed is displayed on the display unit 7 (step S2
9), waiting for detection that any one of them is selected as the destination (step S3)
0).

Then, when it is determined that the selection and detection of the transmission destination are made, the paging type flag F2 is determined by the contents of the telephone directory data memory area TD of the selected transmission destination.
The column of is referred to (step S31).

Then, it is judged whether the content of the paging type flag F2 set in the above step S19 or the content of the paging type flag F2 referred to in the above step S31 is "1" or "0" (step). S
20).

If the content of the paging type flag F2 is "0", it means that the image cannot be transmitted because the message with the image data attached cannot be transmitted to the destination. After the guide message is displayed on the display unit 7 (step S32), the process returns to step S14 to specify the destination again.

When it is determined in step S20 that the content of the paging type flag F2 is "1", the image data can be attached to the message and transmitted to the destination. In addition to the set message and image data, the individual call number of the destination is set in the transmission data memory 12 (step S21).

Thereafter, with the speaker 19 in contact with the transmitter of the nearest telephone, while waiting for an instruction to actually execute transmission (step S22), it is determined whether or not the instruction is detected (step S22). The process of step S23) is repeated.

Then, when it is judged that it has been detected, the individual calling number of the transmission destination set in the transmission data memory 12 is first converted into a DTMF signal having a digital value and transferred to the transmission buffer 16, and the D / A is transmitted. The individual calling number of the destination by the DTMF signal is transmitted from the speaker 19 via the conversion unit 17 and the amplifier 18 (step S24).

Subsequently, while waiting for an instruction to execute the transmission again (step S25), it is judged whether or not the instruction is detected (step S26), which is repeated.

When it is determined that the message data has been detected, the message data set in the transmission data memory 12 and the image data attached to the message data are converted into digital value DT.
Convert to MF signal and transfer to MF buffer 16
The speaker 19 sends the message data and the image data by the DTMF signal through the A / A converter 17 and the amplifier 18 (step S27), and the processing in the message transmission mode of FIGS. 12 to 14 is completed.

FIG. 19 shows an example of the data structure of the message part in the message field output from the speaker 19 at this time. Here, it is assumed that two frames are transmitted according to the capacity of the attached image data. .

That is, in the message field of the first frame shown in FIG. 19A, an image identification code indicating that image data is attached and the image property data thereof are arranged in addition to the message data, and after that, A division code (1) indicating that a part of the actual image data and the divided image data is present also in the other frames that follow is arranged.

The above-mentioned image property data has an image file name and information for prohibiting copying, and is included in the first frame here.
It may be included in other frames after the second frame.

In the message field of the second frame shown in FIG. 19 (2), the actual image data remaining after the image identification code indicating that the image data is attached, and the following other frames are also displayed. If there is divided image data, a division code (2) is provided, or an end code is provided when the transmission of image data is completed in this second message field.

The size and capacity of the image data attached to the message data and transmitted by the paging receiver are variable as illustrated in the configuration of the image data management memory area IMM in FIG. Except for the information providing service, even the smallest one shall be divided into two frame message fields for transmission as shown in FIG. 19 above, and the larger one should increase the numerical value of the above division code as many times as necessary. Shall be divided into frames and transmitted.

Further, in step S05, no image is attached corresponding to the address data for the information providing service of the message, and the corresponding image flag F1 is set to "1" in the stored contents of the ID-ROM 9 in FIG. When it is determined that the transmission is not based on the address data corresponding to the frame number '87' or the frame number '103' in which "is set," or it is determined that the instruction input to attach the image was not made in step S07. In this case, it is assumed that the image data attached to the message is not transmitted, and only the newly input or selected message is set in the transmission data memory 12 (step S35), and then the destination is displayed on the display unit 7. Send with the guide message that prompts you to enter the designated instruction displayed (step S36) Is newly waited for, or it is repeatedly waited for detection of selecting a telephone number already stored in the telephone directory data memory area TD of the RAM 10 as a destination (steps S37 and S42). ).

When it is determined in step S37 that a new destination has been input, a guide message prompting the user to input data to the telephone directory data memory area TD including at least the individual call number and paging type is displayed on the display unit 7. Is displayed (step S38), and thereafter, while sequentially accepting the input operation from the key input unit 8 (step S39), the process of waiting for the completion of the input to be detected (step S40) is repeated.

When it is determined in step S40 that the end of input has been detected, the contents of the flag F2 indicating whether or not image data can be received corresponding to the paging type are stored in the telephone directory data memory area TD. The setting is input to the corresponding position (step S41).

If it is determined in step S42 that the telephone number already stored in the telephone directory data memory area TD is selected as the destination, it is registered in the telephone directory data memory area TD. In the state where a list of the names that are displayed is displayed on the display unit 7 (step S4
3), waiting for detection that any one of them is selected as a destination (step S4)
4).

Therefore, after the paging type flag F2 is set in the step S41 or after it is determined that the selection of the transmission destination is detected in the step S44, the individual call of the transmission destination is added to the previously set message. The number is set in the transmission data memory 12, and the speaker 19 is in contact with the transmitter of the nearest telephone while waiting for an instruction to actually perform transmission (step S4).
5) Then, it is judged whether or not the instruction is detected (step S46), and the processing is repeated.

Then, when it is judged that it has been detected, the individual calling number of the transmission destination set in the transmission data memory 12 is first converted into a digital value DTMF signal and transferred to the transmission buffer 16, and the D / A is transmitted. The individual calling number of the destination by the DTMF signal is transmitted from the speaker 19 via the conversion unit 17 and the amplifier 18 (step S47).

Subsequently, while waiting for the instruction to execute the transmission again (step S48), it is judged whether or not the instruction is detected (step S49), which is repeated.

When it is determined that the message is detected, the message data set in the transmission data memory 12 is converted into a digital value DTMF signal and transferred to the transmission buffer 16, and the D / A converter 17 and the amplifier The message data by the DTMF signal is transmitted from the speaker 19 via 18 (step S50).
The process in the message transmission mode of FIG. 14 is terminated.

Next, the processing contents when an incoming call is detected by a paging receiver similar to the paging receiver whose circuit configuration is shown in FIG. 1 will be described with reference to FIG.

The figure shows the contents of processing executed when a frame registered in the ID-ROM 9 of the device itself and an incoming call matching the address data and vector data are detected. The minute is taken into the reception data processing circuit 5 (step S60), and it is first determined whether or not the image identification code is set in the message field (step S61).

If it is determined that the image identification code is not set and the image data is not attached to the message field in which the incoming call is detected, then it is determined whether or not there is message data (step S65).

If it is determined that there is message data, the notification driver 13 performs notification of an incoming call using the notification driver 13 and the speaker 15 upon detection of an incoming call, and at the same time the received message data is displayed on the display unit 7. Then, it is displayed and output (step S66), and the processing upon arrival of an incoming call is completed.

If it is determined in step S65 that there is no message data, only the notification driver 13 and the speaker 15 perform the incoming call notification by the notification driver 13 as it is (step S65). In step S72, the processing upon arrival of the call is completed.

If it is determined in step S61 that the image identification code is set in the message field of the received frame, the content of the division code attached to the end of the message field is (1 ), (2) transition or end code in place of split code, or whether a code similar to split code and end code is set (step S62).

If it is determined in step S62 that the division code attached to the end of the message field is (1), that frame is the frame located at the beginning of the series of image data, and the image identification code is followed. Since a part of the first image data is arranged and the image property data may be arranged, a new image management address is set in the image data management memory area IMM, and the image property is set. If the data is arranged, the copy prohibition flag F3, the copy flag F4, the file name, etc. are stored based on the property data (step S63), and then the corresponding file name is also set in the image data storage area IMGD. The image data is set and stored (step S64).

Thereafter, the process proceeds to step S65, and it is determined whether or not there is message data together with image data in the message field. If it is determined that there is message data, the process proceeds to step S66 to detect the incoming call. The notification driver 13 and the speaker 15 are used to perform the incoming call notification, and at the same time, the received message data is displayed and output on the display unit 7, and when it is determined that there is no message data, the above is directly performed. In step S72, the notification driver 13 performs only notification of an incoming call by using the notification driver 13 and the speaker 15 upon detection of an incoming call.

Further, it is determined whether or not there is message data in step S62 (step S65).

If it is determined that there is message data, the notification driver 13 performs notification of an incoming call using the notification driver 13 and the speaker 15 upon detection of an incoming call, and at the same time the received message data is displayed on the display unit 7. Then, it is displayed and output (step S66), and the processing upon arrival of an incoming call is completed.

If it is determined in step S62 that the end of the message field is a division code or end code after (2), that frame is the second or subsequent frame of the series of image data. Since a part of the image data is arranged following the image identification code and the image property data may be arranged, the image property is set to the image management address set in the image data management memory area IMM. If the data is arranged, the copy prohibition flag F3, the copy flag F4, the file name, etc. are stored based on the property data (step S67), and then the corresponding file name set in the image data storage area IMGD. Image data is added and stored (step S6
8) Then, it is determined whether or not a division code or an end code is set at the end of the message field (step S69).

If it is determined that the division code or the end code is set, this processing is ended and the process proceeds to the next incoming call. However, if a code other than the division code or the end code is set. If it is determined, or if it is determined in step S62 that none of the division code (1) or division code (2) or the end code or the end code is placed at the end of the message field, the message in the received frame Whether or not the field is based on a specific information providing service is determined based on a specific identification code attached (step S70), and only when it is determined to be the specific information providing service, the file name and ID-RO
Writing is performed to additionally set a new image management address in M9 (step S71), and the processing upon reception of an incoming call is completed.

21 and 22 exemplify the display state of message data to which image data is attached as described above. As shown in FIG. 21, in the state in which the content of the message data received on the display unit 7 in the process of step S66 is displayed “There is a bargain for tomorrow”, other data is displayed at the bottom of the display unit 7. For example, the symbol a
Display with.

In response to this display, by operating, for example, the downward cursor key of the key input unit 8, the image data attached to the message data is displayed and output on the display unit 7 as shown in FIG. Let In this case, the sender name b shown as “Takeshi Ogawa” in the figure indicates that this image data is copied by the sender.

In the above embodiment, the copying is restricted in two steps: when the copying of the image data is completely prohibited, and when the information indicating the sender is inserted in the image and the transmission itself is permitted. Therefore, it is possible to realize the setting of the limitation regarding copying for each image data as needed.

Further, the configuration shown in FIG. 23 may be replaced with the configuration shown in FIG. 10 instead of the configuration shown in FIG. In this case, a new attachment information data memory area AD is provided, and although copying is not prohibited, if some kind of image information indicating that it was copied in the image needs to be attached, the image information to be attached Can be stored in the attached information data memory area AD.

FIG. 23 exemplifies the storage contents in the attached information data memory area AD. Instead of the notation of the sender's name indicating that the image is a copy in the image shown in FIG. Alternatively, a plurality of images representing the seal of the user and images representing the electronic mail address may be prepared as symbols, and may be appropriately selected and attached.

In addition, the present invention can be variously modified and implemented within the scope of the invention.
