DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An image display pager according to an embodiment of the present invention will be described with reference to the drawings. Image display pagers are used as mobile communication devices such as mobile phones and pagers, receive paging data wirelessly transmitted from a sender via a base station, and display image information based on the paging data on the surface of the pager case. The information is displayed on a display such as a liquid crystal provided in an exposed manner.

As shown in FIG. 1, the image display pager 10 receives a paging data D transmitted wirelessly, a decoder 12 for decoding the received paging data D, and a paging data D. An image memory 13 such as a VRAM for storing image data for one screen obtained by decoding, and a display unit 14 for reading image data from the image memory 13 and displaying the image data on a display 14a
A ringing control unit 15 for generating a ring tone from the speaker 16 when the received paging data is addressed to the own device, a central processing unit (CPU) 17 for controlling the operation of each of the functional units 11 to 15, ,have. The display 14a has, for example, 80 pixels × 16 pixels as shown in FIG.
It is a liquid crystal display panel composed of a large number of pixels g such as 0 pixels, and can display arbitrary image information such as a map by displaying each bit of binarized image data for each pixel.

As shown in FIG. 4, the paging data D is a data part D1 for storing image data and character data.
And a header portion, and the header portion includes identification information (I) for identifying the pager 10 as a transmission destination.
D) A column indicating the relationship between D2, data type information D3 indicating the type of data stored in the data section D1, and partial image data when partial image data is stored in the data section D1 as described later. Information D4 is included.

Here, the image data stored in the data section D1 is not limited to the case where the image data is for one screen of image information.
The image data may be partial image data obtained by dividing image data for a screen into a plurality of pieces, and is arbitrarily set according to the size of paging data D that can be transmitted or received at one time and the size of image data to be transmitted. Therefore, even when the size of the paging data D that can be transmitted or received is limited, the pager 10 can generally receive large image data by sequentially transmitting and receiving the partial image data.

The receiving unit 11 determines whether the paging data D is addressed to the own device from the identification information D2 of the received paging data D, and transmits only the paging data D addressed to the own device to the decoder unit 12. . Decoder section 12
As shown in FIG. 3, has a type determination unit 18, a number / character correspondence control unit 19, and a number / character reference memory 20, and decodes the paging data D sent from the reception unit 11.

The decoder unit 12 decodes the paging data D and sends a signal to the sound control unit 15 to generate a ringtone indicating that the paging data D has been received by the speaker 1.
Start from 6. Note that an oscillating unit may be provided together with or instead of the sound control unit 15 to notify the recipient of the reception of the paging data D by the vibration of the pager 10.

The type determining unit 18 determines the data type information D for the paging data D sent from the receiving unit 11.
3 to determine the type of data stored in the data part D1. If the data stored in the data section D1 is image data, the type determination section 18 extracts the image data from the data section D1 and sends it to the image memory 13, while if the data stored in the data section D1 is character data, The data is extracted from the data section D1 and sent to the number / character correspondence control section 19.

Here, when the partial image data is stored in the data part D1, the type determining part 18 converts each partial image data of the paging data D received sequentially into the column information D4.
To the image memory 13 based on the
To reproduce the image data for one screen. The image data is binary data corresponding to the original image information, for example, "1" is turned on the pixel and "0" is turned off the pixel.
As shown in (1), binary image data for one screen is stored in the image memory 13 in a state where the original image information is reproduced. Therefore, each piece of image data constituting the original image information must be stored in a corresponding column position in the image memory 13, and column information D4 is added to the paging data D to indicate this column position.

The number / character correspondence control section 19 converts the character data sent from the type determination section 18 into image data representing the corresponding number or character by referring to a reference table stored in the number / character reference memory 20. The image data is converted and stored in the image memory 13. The character data is, for example, 8-bit code data, and numbers and characters are assigned to the respective code data.

Correspondingly, the numeral / character reference memory 2
0 stores a reference table such as that shown in FIG.
"0" is a number "2", "00010000" is a character "
A, "00100001" describes image data in a predetermined font of numbers and characters in association with character data, such as the English character "A". Table 20
, Image data representing the corresponding numbers and characters is obtained from the character data based on the
3 is stored. For example, if the character data is "0000"
If it is 0010 ", the image data representing the number" 2 "is retrieved from the reference table 20 and stored in the image memory 13 as shown in FIG.

An image display method using the image display pager having the above configuration will be described with reference to a flowchart shown in FIG. First, when the receiving unit 11 receives the paging data D (step S1), it determines from the identification information D2 whether or not the paging data D is addressed to the own device. Send it to the decoder unit 12.

The data coder unit 12 checks the data type information D3 of the paging data D by the type determination unit 18 (step S2). If it is determined that image data is stored in the data unit D1, the type determination unit 18 Is the data part D1
Then, the image data is taken out and stored in the image memory 13 (step S3). Note that the type determination unit 18 determines the level information D4
Also, it is checked whether or not the partial image data is stored in the data portion D1, and in the case of the partial image data, the partial image data is extracted from each of the received paging data D, and these partial image data are stored in the image memory based on the column information D4. 13
And the image data for one screen before division is reproduced in the image memory 13.

On the other hand, when it is determined that character data is stored in the data portion D1, the type determining portion 18 extracts the character data from the data portion D1 and outputs
It is transferred to the character correspondence control unit 19. The numeral / character correspondence control unit 19 converts the character data into corresponding numeral or character image data with reference to the table 20 of the numeral / character reference memory (step S4), and stores this image data in the image memory 13. (Step S3). Therefore, rather than transmitting and receiving image data by including it in paging data D, rather than transmitting and receiving character data by including it in paging data D and obtaining image data from the character data using reference table 20 on pager 10 side, The amount of data to be transmitted / received is small, and quick transmission / reception processing is performed.

When one screen of image data is stored in the pixel memory 13, the display unit 14 reads out the image data from the image memory 13 and displays image information composed of the image data on the display 14a (step S5). Then, the message from the sender is transmitted to the pager carrier as image information. The reception of such a message is also notified by a ring tone from the speaker 16.

Therefore, according to the above-described pager and image display method, a message from a sender can be obtained by using arbitrary image information (a figure, a diagram, a mark, characters and numbers in an arbitrary typeface, etc.) other than characters and numbers. Is displayed, and various kinds of information can be obtained by the pager 10 as compared with the related art. The display of image information by the pager 10 can be performed, for example, by transmitting the image data from the central office to the pager 10 via a wireless or wired telephone line using an image processing device such as a personal computer or a facsimile. Is easily transmitted.

As another embodiment of the present invention, image data or partial image data may be compressed and stored in the data section D1. In this case, the pager 10 can be transmitted by one transmission of the paging data. A large amount of image data can be sent to the pager 10, or the image information can be quickly transmitted to the pager 10 by reducing the paging data D. In order to cope with this, means for expanding image data according to a preset compression method is provided by a pager 10.
In this case, the image data may be stored in the image memory 13 after being decompressed.

As an example of this compression method, for example, if the image data is “000000000111100001100”
0 ... ”, then“ 0814041203 ...
・ A number indicating "0" or "1" like "
Compression is performed by replacing a sequence of numbers paired with the number of 0s or 1s.
Four 1s are arranged, then four "0s" are arranged, and then "
The original image data is represented by a number in which "0" and "1" are successively successively compressed, for example, two "1" are arranged, then three "0" are arranged, and so on.

As another example of the compression method, the initial value "0" or "1" of the image data is shown, and thereafter, only the continuous number of "1" or "0" which repeats sequentially is described. Compress image data. In the above example, the image data is represented as “0844323.
Eight consecutive "0", then four consecutive "1", then four consecutive "0", then "1"
Are consecutively arranged, then “0” is consecutively arranged three times, and so on. Note that these "0"
Or the number of "1" is transmitted as binary data,
For example, rather than arranging "0" or "1" in 8 bits, "
Clearly smaller data is represented by 1 bit representing 0 "or" 1 "and 3 bits representing 8.

In the above-described embodiment, the partial image data has a size corresponding to one screen of image data of one screen in the image memory 13. However, in accordance with practical requirements, the present invention provides two steps of partial image data. The size can be set as described above, or can be set to an arbitrary size regardless of the level. In this case, the column information D4 is also information corresponding to these.
