[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication terminal device such as a mobile phone, a simple mobile phone (PHS), and a personal digital assistant (PDA), and more particularly to a mobile communication terminal device capable of efficiently storing and displaying image data such as map data.
[0002]
[Prior art]
A mobile communication terminal device such as a cellular phone has a small display screen size and a small data storage capacity, so in the case of image data, it often does not fit on one screen and is displayed in a switched manner. The display image must be closed once and another file must be selected again, and cannot be displayed successively one after another.
[0003]
In the case of map data, if you want to see the map after scrolling a map that is larger than the screen size to the end of the screen, you must import new map data again. Such a cumbersome operation is required.
[0004]
When looking only at the technology for scrolling and displaying map data beyond the category of mobile communication terminal devices, for example, the technology disclosed in the following publication is conventionally known.
[0005]

[0006]
(2) Japanese Patent Laid-Open No. 4-364579 A neighboring position management file that is pre-corresponding to graphic (map) data is prepared separately from graphic data, and the neighboring position map appears on the display unit by designating with the mouse. Browse the management file and display the specified figure.
[0007]
[Problems to be solved by the invention]
However, such a conventional technique is suitable for a personal computer or a CAD system having a large screen size and a sufficiently large data storage capacity, but a mobile phone having a small display screen size and a small data storage capacity. It is not suitable for the portable communication terminal device. In addition, there is no degree of freedom, such as the entire map (a set of unit graphics) displayed in combination is limited to a square.
[0008]
The present invention displays image data of a size that does not fit on a single screen in consideration of the limitations that a mobile communication terminal device such as a mobile phone has a small screen size and a small data storage capacity. In this case, continuous display can be performed with a simple scrolling operation without a troublesome operation such as having to re-import the image data over and over again. Further, the entire form of the image data to be displayed in combination is not specified, and can be freely changed in any of the upper, lower, left and right directions.
[0009]
[Means for Solving the Problems]
That is, the present invention stores the received image data as an image file in a portable communication terminal device that can store the image data received by the transmission / reception unit as an image file in the storage unit, read it, and display it on the display unit. When the image data of the image file is displayed on the display unit, the attribute information adding means for adding the link information indicating the image file of the image data to be linked to the image file as attribute information when the image data of the image file is displayed on the display unit. A display control unit that reads the image file to be connected from the storage unit with reference to the connection information added to the image file, and allows the image data of both image files to be scroll-displayed on the display unit by a scroll operation; It is characterized by that.

When one image file is displayed, another image file can be continuously displayed on the display unit without reselecting the image file one by one. Further, regarding the map data, if the user wants to see the map next to the display map but the adjacent map is not saved, the distribution request for the adjacent map can be automatically made and displayed on the display unit.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0017]
FIG. 1 is a block diagram showing a configuration example of a mobile phone to which the present invention is applied. This cellular phone includes an antenna 1 for receiving and transmitting wirelessly, a transmission / reception unit 2 for demodulating or modulating data received or transmitted from the antenna 1, and a GPS antenna 3 for catching radio waves transmitted from GPS satellites. A GPS unit 4 that calculates latitude / longitude information of the current position from GPS data received from the GPS antenna 3, a keyboard 5, a control unit 6 that performs processing and control of various operations of the mobile phone, a map / image For example, a storage unit 7 for storing data, a temporary storage unit 8 for temporarily storing data, and a display unit 9 for displaying data being received and a data file stored in the storage unit 7.
[0018]
The keyboard 5 has scroll operation keys used for scrolling the display screen on the display unit 9 in the vertical and horizontal directions, in addition to necessary function keys such as a numeric keypad and a key for performing registration registration of data. ing. Particularly used in this example are a link registration key for link registration of data, a key for determining the link direction, and a scroll operation key for scrolling in the vertical and horizontal directions. These may be provided separately, or two or more functions may be shared by one key.
[0019]
For example, as shown in FIG. 2, when one multi-function key 10 is used to perform file registration registration, determination of up / down / left / right connection directions, and up / down / left / right scrolling of the display unit 9, When the center portion is pressed, the link registration switch is turned on to enter the file link registration mode, and when the center portion is pressed again, the link registration switch is turned off to cancel the link registration mode. When the upper part of the key 10 is pressed in the released state, the up scroll switch is turned on and the display on the display unit 9 is scrolled up. When the lower part is pressed, the down scroll switch is turned on and the display on the display unit 9 is displayed. When scrolling down and pressing the left part, the left scroll switch is turned on and the display on the display unit 9 is scrolled to the left. When the right part is pressed, the switch for right scrolling is turned on and the display on the display unit 9 is Scrolled. On the other hand, in the connection registration mode, when the upper scroll switch is turned on by pressing the upper part of the key 10, the file connection direction is turned up, and when the lower scroll switch is turned on by pressing the lower part, the file connection direction is turned down, When the left scroll switch is turned on by pressing, the file connection direction is determined to be left, and when the right part is pressed and the right scroll switch is turned on, the file connection direction is determined to be right. In this way, the number of keys on the keyboard 5 can be reduced and the operation is easy to understand.
[0020]
When image data such as map data is received by the transmission / reception unit 2 and the connection registration operation is performed on the keyboard 5 as described above, the control unit 6 adds attribute information to the head of the received image data. Save in the storage unit 7. FIG. 3 shows an example of the data format at that time, (A) is the received data, and (B) is the saved data. Saved data is obtained by adding attribute information that is unique information of the received data to the beginning of the received data. The attribute information includes a management number that is a serial number of the data file and a concatenation indicating a file that is concatenated with the data file. Contains information.
[0021]
FIG. 4 is a communication system diagram showing an example of use of the mobile phone according to the present invention. The GPS unit 4 built in the cellular phone 401 intermittently receives a signal from the GPS satellite 408. The mobile phone 401 is wirelessly connected to the mobile phone network 402, and the built-in transmission / reception unit 2 and the fixed phone terminal 405 connected to another mobile phone terminal 403 or PSTN (public telephone network) 404 are connected to the voice. Communication can be performed, and data communication can be performed with the server 407 connected to the Internet network 406. At that time, the map data of the current location can be requested to the server 407 by using the latitude / longitude information received by the GPS unit 4. Of course, other image data can be requested from the server 407.
[0022]
Next, an example of the operation of the mobile phone will be described.
FIG. 5 is a flowchart for explaining a reception sequence in which the mobile phone receives data from the server.
[0023]
First, a reception sequence for requesting a map around the current position from the server 407 and receiving processing will be described. When requesting map data of the current location (YES in step S101), first, latitude / longitude information sent from the GPS satellite 408 is received and received by the GPS unit 4 (S102). Upon receiving this, the control unit 6 sends the latitude / longitude information to the transmission / reception unit 2 for modulation processing, and requests distribution of map data to the server 407 via the mobile phone network 402 and the Internet network 406 of FIG. S103). When the map data accompanying the map distribution request is received from the server 407 (S104), it is temporarily stored in the temporary storage unit 8 after being demodulated by the transmission / reception unit 2 (S105). Then, the temporarily stored map data is displayed on the display unit 9 (S106).
[0024]
When image data other than the map data accompanying the map distribution request (NO in S101) is received from the server 407 (S104), similarly, after demodulating by the transmission / reception unit 2, it is temporarily stored in the temporary storage unit 8 (S105). Then, the temporarily stored image data is displayed on the display unit 9 (S106).
[0025]
Next, when the link registration switch is turned on on the keyboard 5, the process proceeds to link registration processing (link registration mode). First, it is confirmed whether or not there is a free area for storing the map / image data in the storage unit 7 (S107). If there is, the linked registration mode is set (YES in S108) and the map / image data is stored. After confirming that the file exists (YES in S109), the map / image data is linked to the existing image file. An image of the connection is shown in FIG.
[0026]
In FIG. 6, for convenience, an image currently displayed on the display unit 9 is referred to as a file A. Normally, when the display image is scrolled up, down, left, and right, the scrolling is completed when it reaches the end of the image (when all the images are displayed on the display unit 9, the scroll operation is not performed). Therefore, when the image file B is connected and registered in the image file A as shown in FIG. 6, when scrolling up to the upper end of the file A, the file B corresponding to the upper end of the file A is read from the storage unit 7, It is displayed on the display unit 9. Similarly, when the file B is displayed and scrolled to the right end of the file B, the file C corresponding to the right end of the file B is read from the storage unit 7 and displayed. In the same manner, when the end of the display file is reached and the scroll operation is further performed, if there is a file registered for connection there, the file is displayed on the display unit 9.
[0027]
Now, link file registration is performed on the received map data (YES in S109). In the state where the map data to be registered is displayed, it is determined which side of the upper, lower, left and right side the file is connected (S110). For example, by turning on a right scrolling switch corresponding to “right side determination”, the connection side is determined to the right side. Next, a file to be connected is selected and determined from the image files stored in the storage unit 7 (S111). When another file is connected and registered on the other side other than the right side of the map image (YES in S112), the same registration operation is repeated (S110 to S112). When the link registration is completed (NO in S112), attribute information is added to the top of the map data (S113).
[0028]
As shown in FIG. 3, the attribute information includes a management number, which is a serial number unique to the file, and link information registered and linked as described above. As the management number, 1 (binary data: 0001), 2 (binary data: 0010), 3 (binary data: 0011), 4 (binary data: 0100). As the connection information, there are four-side connection information including upper-end connection information, right-end connection information, lower-end connection information, and left-end connection information, each of which contains a management number of the registered file. In addition, 0 (binary data: 0000) is entered when there is no link registration. The data string is added to the top of the map data in the order of management number, upper end link information, right end link information, lower end link information, and left end link information. In the example of FIG. 3B, the management number 0011 file is connected to the right side and the management number 0001 file is connected to the lower side of the management number 0011 file.
[0029]
After the attribute information is added, the map data to which the attribute information is added is stored as one file in the storage unit 7 (S114). At this time, the attribute information of each existing file in the newly connected storage unit 7 is also changed and overwritten.
[0030]
If the received map / image data is not connected to a file (NO in S108), and if there is no saved map / image file in the storage unit 7 even if file connection is desired (YES in S108, S109). NO), the attribute information of “0” is added to the received map / image data for the management number and the top / bottom / left / right end link information (S113) and stored in the storage unit 7 (S114).
[0031]
Next, the display sequence of the linked and registered files will be described using the flowchart of FIG.
[0032]
When an image file stored in the storage unit 7 is selected (S201), the selected image data is displayed on the display unit 9 (S202). Thereafter, when the scroll operation is performed and the image is further scrolled (S203 / S205 / S207 / S209), the control unit 6 reads the corresponding connection information in the connection information portion of the image file (S204 / S206 / S208 / S210). For example, when the file of FIG. 3B is displayed, when scrolling down and further scrolling down at the lower end of the image (NO in S203, YES in S205), the control unit 6 displays the lower end connection information of this file. Read (S206). Since the bottom link information is “0001” (NO in S211), the file having the management number “0001” is searched from the files stored in the storage unit 7 (S213). Then, the currently displayed file is closed, and a new file whose management number is “0001” is displayed on the display unit 9 (S202). The subsequent operation is the same.
[0033]
Also, in the above example, when the first display screen is not scrolled down but scrolled up (YES in S203, S204), since the read connection information is “0000” (YES in S211), this is the connection registration. This indicates that there is no file that has been read, and that effect is displayed on the display unit 9 (S212), and the display returns to the original display screen.
[0034]
When the display is to be ended (YES in S214), the file being displayed is closed (S215) and the process is ended.
[0035]
Next, another embodiment of the present invention will be described. In this example, steps S301 to S305 as shown in FIG. 8 are further added after step S212 in the flowchart shown in FIG. 7, and if the map data file corresponding to the link information does not exist in the storage unit 7, a new The map data distribution request can be made.
[0036]
FIG. 9 shows an example of the data format in this case, where (A) is received data, (B) is saved data, and (C) is map request transmission data. In the received data of (A), latitude / longitude information and scale information are added as map attribute information at the head of the map data, and the map attribute information is added from the server 407 and transmitted. The saved data (B) is obtained by adding attribute information, which is unique information of the data, to the top of the received data including the map data and the map attribute information. The attribute information includes a management number that is a serial number of the data file. A number and concatenation information indicating a file concatenated with the data file are included. The map request transmission data (C) is transmitted with the request information indicating the requested direction added after the map attribute information.
[0037]
In step S113 shown in FIG. 5, data identification information is newly added as attribute information to be added to the stored data. This identification information identifies whether the received data is map data or other image data. For example, if the identification information is “1”, it is map data, and if it is “0”, the other image data.
[0038]
Now, assume that a file having the configuration of FIG. 9B is opened and map data is displayed on the display unit 9. In this case, all the connection information is “0000” (no connection file).
[0039]
In step S212 of FIG. 8 (same as S212 of FIG. 3), the display unit 9 displays that there is no linked file, and then the identification information is determined (S301). If the identification information is “1” (YES in S301), that is, if the current display image is map data, the map attribute information is read (S302), and transmission data is generated by adding the requested direction information to this map attribute information. (S303). The requested direction information is information indicating the upward (north), downward (south), left (west), and right (east) directions with respect to the current display image. For example, the binary number “00” is an upper binary number. “01” represents the lower binary number “11” represents the right, and the binary number “10” represents the left. In step S212, if “no linked file” is indicated by turning on the up scroll switch on the keyboard 5, the requested direction information in this case is “00”. If the identification information is “0” in step S301, the current display image is not map data, and the process returns to the original.
[0040]
After the transmission data is generated (S303), the data is modulated by the transmission / reception unit 2 and transmitted from the antenna 1 to the server to make a map distribution request (S304).
[0041]
On the server 407 side, transmission data is determined and distributed based on the map attribute information and the requested direction information. In this example, map data with the same scale and center latitude and longitude information of one screen “north” is distributed.
[0042]
After the map distribution request (S304), the process proceeds to a reception sequence, and distribution map data is received (S305).
[0043]
By doing the above, when the map is displayed and scrolled and reaches the end of the map, even if there is no continuous map, it is possible to automatically make a map data distribution request and display the continuous map It becomes.
[0044]
Although the embodiment applied to the mobile phone has been described above, it is apparent that the present invention can be applied to other mobile communication terminal devices such as a simple mobile phone (PHS) and a personal digital assistant (PDA).
[0045]
【The invention's effect】
The first effect of the present invention is that while one image file is displayed, the image is moved up, down, left and right one after another without having to go through the troublesome procedure of closing the file once and reselecting and displaying another file. It is possible to display different files one after another simply by scrolling in the direction. In addition, the entire form of the image data displayed in combination is not specified, and can be freely changed in any of the upper, lower, left and right directions.
This is because each image file has “attribute information” indicating the file to be displayed next when scrolling to each edge of the image.
[0046]
The second effect is that only related image data can be selected and continuously displayed by image scrolling, and related images can be grouped as one series.
The reason is that the file itself has “attribute information” for concatenation, so that no matter how many classification sequences are added, the processing procedure does not change, and there is no need for complicated management.
[0047]
The third effect is that the file type is not selected regardless of whether the file to be linked is map data, other image data, an enlarged view, or a reduced view.
This is because the connection state is managed only by the default attribute information added to the top of the display data, and therefore does not depend on the display data itself.
[0048]
The fourth effect is that the time-series display of images is easy.
The reason for this is that the linked display of images is assigned to the up / down / left / right scroll keys, and the data is managed, so it is easy to register different images for each series, vertical / horizontal series. The operation is also simple.
[0049]
A fifth effect is that if there is no linked file in the map data, it is possible to automatically receive and display the following map data from the server.
The reason is that when the server distributes the map, the map attribute information is also distributed, so the map attribute information and the requested direction information are returned to the server to receive and display the desired map data. Because it can.
