DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 is a block diagram showing an embodiment of the present invention, FIG. 3 is a flowchart of the embodiment, and FIG. 4 is an explanatory view of the embodiment. The same reference numerals denote the same objects throughout the drawings.

The digitizer 3a and the display (for example, a liquid crystal display, hereinafter referred to as LCD) 4a shown in FIG.
2 corresponding to the input screen 3 and the display screen 4, respectively, and the input detection unit 6 and the recognition unit 21a in FIG. 2 are the first recognition means 21 in FIG.
(Also the second recognition means of claim 2 and claim 3)
(Corresponding to the third recognition means).

In the block diagram of FIG. 2, the pen input device includes a CPU 1, a ROM 2, a digitizer 3a, an LCD 4a,
Input pen 5a, input detector 6, image data file 7
a, the RAM 8, the recognition unit 21a, and the correction unit 22 are shown.

The CPU 1 controls each unit according to the management program of the ROM 2 and the like. The ROM 2 is an area for storing a management program 20 for controlling the LCD 4a, the input detection unit 6, the image data file 7a, and the RAM 8 based on the input to the digitizer 3a by the input pen 5a, and the recognition unit 21a.
And an area for storing the correction unit 22.

The input detection unit 6 is data which means a specified range specification operation by the input pen 5a on the digitizer 3a and a drawing operation such as a specific symbol including a character, that is, XY for specifying a range of a gesture. Input data such as coordinate values and symbols are detected.

Here, the standardized range designation operation is, for example, an operation of drawing a circle, a rectangle, or the like in a desired size, and the specific symbol or the like is a character or the like defined corresponding to each figure, and is arbitrary. For example, if the graph 1 is drawn, "pie graph" is drawn, and if the graph 2 is drawn, "bar graph" is specified. Therefore, if a circle of a certain size is drawn around the graph 1 and then tapped inside the circle, the display instruction of the "pie graph" of the size of the circle is input at that position.

The RAM 8 reads the image data corresponding to the symbol to be displayed from the search unit 80 and the image data file 7a, expands it in the display buffer 81, and then L
It has an area for storing a program to be displayed on the CD 4a, a symbol file 82, and a display symbol position file 83. The symbol file 82 stores the symbols set corresponding to specific symbols and the like, and the display symbol position file 83 stores the display positions (coordinates of the display center) of the symbols displayed on the LCD 4a.

The recognition unit 21a is composed of a gesture file 23 and a recognition program 24. The gesture file 23 stores characteristics of various gestures, and the recognition program 24 refers to the gesture file 23 from data such as coordinate values and symbols detected by the input detection unit 6 to display a new symbol, It is a program that recognizes what the gesture is, including changing the size of the display symbol.

The search unit 80 searches the symbol file 81 for a symbol corresponding to data such as a symbol based on the gesture recognized by the recognition unit 21a, and also corresponds to the coordinate value of the range designation of the displayed symbol. It is a program that searches for symbols.

The correction section 22 (corresponding to the first correction means of claim 2 and the second correction means of claim 3) is provided for the symbol corresponding to the data such as the symbol retrieved by the retrieval section 80. This program corrects (enlarges or reduces) the size of dot image data to the size of the symbol corresponding to the coordinate value of the specified range. As the size of the image data is enlarged or reduced, and the dot interval of the image data changes depending on the enlargement / reduction ratio, the dots are interpolated or thinned to the dot interval required for display.

The image data file 7a is the input pen 5a.
Thus, the dot image data corresponding to the symbol represented by the gesture input by operation is stored in advance on the digitizer 3a.

Having such a structure and function, the operation will be described below with reference to the flowchart of FIG. 3 and the explanatory view of FIG. First, as a gesture input, the input pen 5a is used to make a gesture on the digitizer 3a and tap it. (When a new figure is displayed, draw a symbol corresponding to the symbol you want to display and draw a circle to enclose it, as shown in Fig. 4 (a). Also change the size of the already displayed figure. When doing, enclose the center of the figure with a circle of the desired size, as shown in Fig. 4 (c). Then, the input detection unit 6 makes a gesture input, that is, symbol data (when changing the size of the figure). Does not have symbol data.) And the maximum value of X-Y coordinate data of circle /
Find the minimum value.

The detected gesture is based on the maximum value / minimum value of the symbol data and the coordinate data, and the recognition unit 21a.
At, the gesture file 23 is referenced to recognize what data is drawn from the input trajectory.

If there is symbol data in the data (that is,
In the case of newly displaying a graphic), the symbol data is sent to the retrieval unit 80 of the RAM 8 and the symbol data is analyzed to retrieve the corresponding symbol from the symbol file 82.

If there is no symbol data (that is, when the size of the figure being displayed is changed), the display center obtained from the maximum value / minimum value of the XY coordinate data of the circle detected by the input detection unit 6 From the position, the symbol closest to the center position stored in the display symbol position file 83 is searched.

When the target symbol is searched in the above or, the dot image data corresponding to the symbol is read from the image data file 7a. Alternatively, if the target symbol is not found as a result of the search, the size change operation is invalidated.

Next, the correction unit 22 corrects the size of the dot image data of the symbol so that it fits within the display range from the display position / display range obtained from the maximum / minimum values of the XY coordinate data of the circle.

After the corrected dot image data is developed in the display buffer 82, a symbol (in this case, a "pie chart" figure) is displayed on the LCD 4a. When the data is expanded in the display buffer 82 by changing the size, since the data before the size change of the symbol exists at the display position, the data is deleted before the expansion. The center position of the displayed figure is filed in the display symbol position file 83. FIG. 4B shows a case where a new graphic is displayed, and FIG. 4D shows a case where the size of the graphic already displayed is enlarged.

In this way, the image data file 7a of the desired symbol can be read and displayed by gesturing the digitizer 3a with the input pen 5a, and the displayed graphic can be changed to the desired size. Therefore, the operation is significantly simplified.

Although the gesture for newly displaying a graphic in the above example is the case of the enclosing operation of the symbol data and the circle corresponding to the symbol, the enclosing may be a quadrangle.
Of course, a method of gesturing the size of the symbol data with a desired size may be used.

[0035]

As described above, according to the present invention, in claim 1, the drawing operation including the figure and the character is performed by the input pen on the input screen, and the symbol corresponding to the drawing operation is stored in the storage means. Since the image data to be read can be read and the symbol can be displayed at a desired position, it is not necessary to perform selection designation and display position designation from the menu of symbols as in the conventional method, and the operation is extremely simple.

According to a second aspect of the present invention, the size of the image data corresponding to the symbol representing the drawing operation read out from the storage means is corrected to the size of the area occupied by the operated drawing operation so that the desired position can be obtained. Since the symbol can be displayed in the size, the operation of displaying the symbol becomes extremely easy.

According to the present invention, when the size of the symbol displayed on the display screen is changed, only the enclosing operation is performed as a drawing operation, and the size of the displayed symbol is adjusted to the size of the enclosing operation area at the same position. Since it is possible to revise the display, you can redo the display operation by deleting the displayed symbol, specifying the display position and size by the enclosing operation, and then specifying the desired symbol, as in the conventional method. No effort is required, and the size change operation is extremely easy. There is an effect.
