Abstract

A map information system is provided which includes an electronic pen which reads a dot pattern in a form where map images are shown, to output handwriting information, and a processing unit including an association module which associates the output handwriting information with one of the map images where the handwriting information is written and stores it in a storage unit, a search module which searches for the associated handwriting information and map image using information to specify the map image as a search key, a pattern assignment module which when acquiring print request information including information to specify the map images to be printed, newly assigns a dot pattern, and an output instruction module which issues an output instruction so as to cause an output unit to visually output data including the retrieved associated handwriting information and map image and the newly assigned dot pattern.

Claims

1. A map information system comprising:

an electronic pen which reads a dot pattern recorded as position information in a form where one or more map images are shown, to output a trace of a pen tip as handwriting information;

a processing unit; and

a storage unit, wherein

the processing unit comprises;

an association module which associates the handwriting information output by the electronic pen with one of the map images where the handwriting information is written and stores the associated handwriting information and map image in the storage unit;

a search module which searches the storage unit to retrieve the associated handwriting information and map image using information to specify the map image as a search key;

a pattern assignment module which when acquiring print request information including information to specify one or more map images to be printed, newly assigns a dot pattern to the acquired print request information; and

an output instruction module which issues an output instruction so as to cause an output unit to visually output data including the associated handwriting information and map image retrieved by the search module and the dot pattern assigned by the pattern assignment module.

2. A map information system as claimed in claim 1, wherein

the processing unit further comprises

a data merge module which merges the handwriting information associated with the map image with handwriting information which is written in the map image and newly output by the electronic pen, and outputs the merged handwriting information, and wherein

when the data merge module outputs the handwriting information, the association module associates the handwriting information output by the data merge module with the map image and stores the associated handwriting information and map image in the storage unit.

3. A map information system as claimed in claim 2, wherein

when the print request information includes information to specify a plurality of handwriting information which is requested to be merged, the data merge module merges the plurality of handwriting information which corresponds to the information to specify the plurality of handwriting information.

4. A map information system as claimed in claim 1, wherein

the storage unit holds scale correspondence information which includes scale information for map images and information to indicate positional relationship among map images on different scales, wherein

the processing unit further comprises

a scale adjustment module which when a second map image corresponding to the information to specify the map image included in the print request information is detected in the scale correspondence information, multiplies second handwriting information associated with the second map image by a reproduction scale based on scales of the map image and the second map image for adjustment and performs cutout from or insertion of the multiplied second handwriting information based on the positional relationship to create third handwriting information, and wherein

when the scale adjustment module creates the third handwriting information, the output instruction module issues the output instruction so as to cause the output unit to visually output data including the third handwriting information and the map image.

5. A map information processing method in a map information system comprising:

an electronic pen which reads a dot pattern recorded as position information in a form where one or more map images are shown, to output a trace of a pen tip as handwriting information;

a processing unit; and

a storage unit, the map information processing method comprising;

an association step in which an association module of the processing unit associates the handwriting information output by the electronic pen with one of the map images where the handwriting information is written and stores the associated handwriting information and map image in the storage unit;

a search step in which a search module of the processing unit searches the storage unit to retrieve the associated handwriting information and map image using information to specify the map image as a search key;

a pattern assignment step in which when acquiring print request information including information to specify one or more map images to be printed, a pattern assignment module of the processing unit newly assigns a dot pattern to the acquired print request information; and

an output instruction step in which an output instruction module of the processing unit issues an output instruction so as to cause an output unit to visually output data including the associated handwriting information and map image retrieved by the search module and the dot pattern assigned by the pattern assignment module.

6. A map information processing method as claimed in claim 5, wherein

in the association step, when the associated handwriting information and map image have already been stored in the storage unit, a data merge module of the processing unit merges the handwriting information already stored in the storage unit with handwriting information output by the electronic pen, and outputs the merged handwriting information, and the association module associates the handwriting information output by the data merge module with the map image and stores the associated handwriting information and map image in the storage unit.

7. A map information processing method as claimed in claim 6, wherein

in the search step, when the print request information including information to specify a plurality of handwriting information which is requested to be merged is acquired, the data merge module merges the plurality of handwriting information which corresponds to the information to specify the plurality of handwriting information, and wherein

in the output instruction step, the output instruction module issues an output instruction so as to cause the output unit to visually output data including the map image retrieved by the search module, the handwriting information output by the data merge module, and the dot pattern assigned by the pattern assignment module.

8. A map information processing method as claimed in claim 5, wherein

the storage unit holds scale correspondence information which includes scale information for map images and information to indicate positional relationship among map images on different scales, the map information processing method further comprising

a scale adjustment step in which when a second map image corresponding to the information to specify the map image included in the print request information is detected in the scale correspondence information, a scale adjustment module of the processing unit multiplies second handwriting information associated with the second map image by a reproduction scale based on scales of the map image and the second map image for adjustment and performs cutout from or insertion of the multiplied second handwriting information based on the positional relationship to create third handwriting information, and wherein

in the output instruction step, when the adjustment module creates the third handwriting information, the output instruction module issues the output instruction so as to cause the output unit to visually output data including the third handwriting information and the map image.
