The input information storage unit 12 stores a speech recognition result or a mesh number serving as a center of enlargement or reduction and an enlargement / reduction ratio (%) inputted from a keyboard. The conversion control table 13 stores the numbers assigned to the respective meshes and the coordinates (X, Y) of the respective center positions. The information in the conversion control table 13 may be fixedly set in advance, or may be dynamically set when the number of screen divisions is determined. The mesh number is not limited to a numeral, but may be a code or a name as long as each mesh can be distinguished.

FIG. 4 is an enlarged view of a screen in the case of mesh division.
FIG. 5 shows an example of screen enlargement using mesh division. Hereinafter, a case where a map is displayed will be described with reference to the flowchart shown in FIG. The same processing can be performed for other images such as design drawings. Note that FIG. 4 omits processing other than enlargement / reduction related to image processing. Actually, processing corresponding to various commands other than enlargement / reduction is also performed.

First, an image of a map of a designated portion in the map database 31 is displayed on the screen of the display device 4 (step S10). Next, it is determined whether display of a mesh is necessary (step S11). Whether the display of the mesh is necessary is set by the mesh display / non-display switching unit 141 by a mesh display / non-display switching command. The display may be switched to the mesh display state when a command for instructing enlargement / reduction is input instead of the mesh display / non-display switching command.

When the display of the mesh is necessary, the mesh with the auxiliary number is superimposed on the currently displayed map and displayed (step S12). FIG. 5A shows an example of a display screen 41 on which a mesh with an auxiliary number is displayed. In this example, each mesh is numbered from 1 to 16, but may be a code such as A, B, or C. The number of divisions is 1
The number is not limited to six and is optional.

Next, a mesh number, which is the center of enlargement / reduction, is input from an input device other than a pointing device such as a voice input microphone or a keyboard (step S13). In addition, the enlargement / reduction ratio is input by voice or a keyboard (step S14). If the enlargement / reduction ratio is previously determined to be, for example, 200% for enlargement and 50% for reduction, it is only necessary to first input whether to enlarge or reduce, and step S14 is performed.
Can be omitted.

In steps S13 and S14, when the guidance for voice input is displayed on the screen divided into meshes, the following procedure is performed, for example. The same applies to input from the keyboard.

The speech recognition result is stored in the input information storage unit 12.

(3) Next, the guidance output unit 114 outputs a message such as "Please input the enlargement / reduction ratio".
A message prompting the user to input the enlargement / reduction ratio is displayed on the screen.

(4) The voice input unit 111 detects the voice input of the enlargement / reduction rate uttered by the user, and if there is a voice input, performs voice recognition by the voice recognition unit 112 and controls the voice recognition result. Notify section 113. The control unit 113
The speech recognition result is stored in the input information storage unit 12.

When the mesh number and the enlargement / reduction ratio are input, the enlargement / reduction control unit 143 refers to the conversion control table 13 and performs the enlargement / reduction from the input mesh number.
The image data part to be reduced is determined (step S15).
The center position of the image data portion to be enlarged / reduced is determined by searching the conversion control table 13 by the mesh number, and the range is determined from the input of the enlargement / reduction ratio.

Next, the enlargement / reduction unit 153 accesses the map database 31 if necessary according to an instruction from the enlargement / reduction control unit 143, and converts the image at the specified enlargement / reduction ratio centering on the mesh. The result is enlarged / reduced and the result is written into the video memory 16 (step S16). Thereby, the enlarged / reduced image is displayed on the display device 4. For example, when the image data is in the bitmap format, the enlargement / reduction of the image is performed by changing the dot size, and when the image data is the vector data, the entire vector size is changed. Since various methods of these enlargement / reduction processes have been conventionally known, a detailed description thereof will be omitted.

FIG. 5B shows an example of the display screen 42 displayed in an enlarged manner. In this example, on the display screen 41 of FIG. 5A, there is an instruction for enlargement by voice input of the mesh number “11”, and the map of the portion centered on the mesh number “11” is shown in FIG. It is enlarged and displayed like the display screen 42. On this display screen 42, similarly, meshes with auxiliary numbers are displayed, and the screen can be continuously enlarged and reduced.

If it is determined in step S11 that mesh display is not required, it is determined whether an instruction to display no mesh has been issued (step S17). If there is an instruction to hide the mesh, the display of the mesh on the screen is deleted (step S18), and the process returns to step S11 (or step S10). If there is an instruction to end the display (step S19), the process ends.

[Second embodiment (in the case of landmark)] First, as a second embodiment, a landmark is set on a screen, and the landmark information is input.
An example of inputting designation of a center position for enlargement / reduction will be described. FIG. 3B shows an example of information stored in the input information storage unit 12 and the conversion control table 13 in the second embodiment. The input information storage unit 12 stores a landmark name and an enlargement / reduction ratio (%) at the center of enlargement or reduction inputted from the voice recognition result or the keyboard.
Is stored. The conversion control table 13 also stores landmark names as feature points registered in advance in the map of the map database 31 and coordinates (X,
Y) is stored.

In this example, landmark names such as “Tokyo Tower”, “National Diet Building”,... Are used as information for identifying landmarks, but symbols such as A, B, C,. It may be something like a number.

FIG. 6 shows an enlarged view of a landmark.
FIG. 7 shows an example of screen enlargement using landmarks. Hereinafter, a case where a map is displayed will be described with reference to a flowchart shown in FIG. The same processing can be performed for other images such as design drawings.

First, an image of a map of a designated portion in the map database 31 is displayed on the screen of the display device 4 (step S20). Next, landmark information (landmark name or landmark figure and landmark name, etc.)
It is determined whether or not display is necessary (step S21).
Whether the display of the landmark information is necessary is set by the landmark information display / non-display switching unit 142 by a landmark information display / non-display switching command.
When a command for instructing enlargement / reduction is entered instead of a landmark information display / non-display switching command,
The state may be switched to the landmark information display state.

When the landmark information needs to be displayed, the landmark name and the landmark figure are superimposed on the currently displayed map (step S22). If a landmark name or landmark figure is included in the already displayed map, only those not displayed are displayed.

FIG. 7A shows an example of a map display screen on which landmark information is displayed. On the display screen 43, three landmarks having landmark names of A, B, and C are displayed.

Next, the landmark name of the landmark to be the center of enlargement / reduction is input from an input device other than a pointing device such as a voice input microphone or a keyboard (step S23). In addition, the enlargement / reduction ratio is input by voice input or a keyboard (step S).
24). If the enlargement / reduction rate is determined in advance to be, for example, 200% or 50%, the processing in step S24 can be omitted. Step S2
3. In S24, guidance for voice input can be displayed in the same manner as described in the example of mesh division.

When a landmark name and an enlargement / reduction ratio are input, the enlargement / reduction control unit 143 refers to the conversion control table 13 and determines an image data portion to be enlarged / reduced from the input landmark name. (Step S2
5). The center position of the image data portion to be enlarged / reduced is determined by searching the conversion control table 13 by the landmark name, and the range to be enlarged / reduced is determined from the input of the enlargement / reduction ratio.

Next, the enlargement / reduction unit 153 accesses the map database 31 if necessary according to an instruction from the enlargement / reduction control unit 143, and performs image processing at the designated enlargement / reduction ratio centering on landmarks. Is enlarged / reduced, and the result is written into the video memory 16 (step S26). Thereby, the enlarged / reduced image is displayed on the display device 4.

FIG. 7B shows an example of the display screen 44 displayed in an enlarged manner. In this example, on the display screen 43 of FIG. 7A, there is an instruction for enlargement by voice input of the landmark name “A”, and a map centering on the landmark name “A” is shown in FIG. Is enlarged and displayed like the display screen 44 of FIG. Also on the display screen 44, landmarks (A, D, E) with landmark names are displayed in the same manner, and the screen can be continuously enlarged and reduced.

If it is determined in step S21 that the display of the landmark information is not necessary, it is determined whether or not an instruction to hide the landmark information has been issued (step S2).
7). If an instruction to hide the landmark information has been issued, the display such as the landmark name on the screen is deleted as necessary (step S28), and the process returns to step S21 (or step S20). If there is an instruction to end the display (step S29), the process ends.
