DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings.

FIG. 1 shows the structure of an information processing apparatus adopting the present invention.

In FIG. 1, reference numeral 10 is a CPU which comprises a microprocessor and controls the entire apparatus. The later-described control processing procedure of the CPU 10, display fonts, and the like are stored in the ROM 11, and the RAM 12 is used to store the work area of the CPU 10 and various data.

The display circuit 13 is composed of a liquid crystal or a CRT and a memory, and the input tablet 2 of the coordinate input device 20.
Various data such as image characters stored in the memory is displayed at the lower part of 1 to form a handwritten character input / display unit together with the coordinate input device 20.

The coordinate input device 20 comprises a digitizer using a resistance film in this embodiment. The coordinate input device 20 has a transparent input tablet 21 using a resistance film, and coordinates are input by pressing the tablet surface with the input pen 23.

In the handwriting input area in the input tablet 21, as shown in FIG. 3, a character input area 31 for inputting characters and a character modification input area 32 provided near each of the character input areas 31. Is partitioned. Character input area 3
The handwriting character is input and displayed by the input pen 23, or the character is recognized in accordance with the input stroke (coordinate pattern group) and the font of the character is displayed.

FIG. 4 shows the functional blocks of this apparatus. The input unit 41 and the display unit 44 are the coordinate input device 20.
The control unit 43 configured to control the handwritten pattern recognition unit 42 and the display unit 44 is configured by the CPU 10.

FIG. 5 shows an outline of the processing performed by the CPU 10. The illustrated processing procedure is stored in the ROM 11 in advance, or is stored in the RAM from the outside. Here, it is assumed that five character input areas 31 and five character modification input areas 32 are provided as shown in FIG. In the character input area 31 and the character modification input area 32, characters and modification data are sequentially input from the left.

In step S501 of FIG. 5, the counter N for counting the character input area 31 and the character modification input area 32 to be input is reset to 1, and step S5 is performed.
In 02, the input pen 23 is used to input a handwritten character into the character input area 31. At this time, the input handwritten character is stored in a predetermined area in the memory RAM 12.

In step S503, the memory RAM 12
The series of input stroke data stored in the character recognition unit recognizes as a character and converts it into a character code, which is also stored in another area in the memory RAM. Since this recognition processing is publicly known, its explanation is omitted here.

In step S504, the font of the character code obtained as a result of recognition in the RAM 12 is read from the ROM 11 and the character input area 31 of the memory in the display circuit 13 is read.
It is displayed at a position on the display circuit 13 corresponding to the inside.

In step S505, it is determined whether or not an input for designating a character modification has been made in the character modification input area 32.

In the present embodiment, by inputting in the character modification input area 32, the characters displayed in the corresponding character input area 31 are displayed in the character modification input area 32 (or in the character input area 31). Display the decoration. The input in the character modification input area 32 may be a handwriting input. For example, if you want to underline
An underline may be handwritten in the character modification input area 32.

If step S505 is positive,
In step S506, the decoration information is recognized, and in step S507, the corresponding character input area 31 is placed in the character decoration input area 32 (or may be in the character input area 31).
Performs a modified display for the characters displayed in. The recognition of the modification information will be described in detail later.

In steps S508 and S512 to S515, the erasing process is performed according to the finger point input (input of only one point) to the character modification input area 32. When the finger point input is detected once in step S508, step S512
At step S513, the display in the character input area 31 is reversed. When the finger-point input is detected again at step S513, the display in the character input area 31 is erased at step S514. If the second finger input is not detected,
In step S515, the reverse display in the character input area 31 is continued.

In step S509, the value of the counter N becomes 5, and it is determined whether or not all the character input areas 31 or the character modification input areas 32 have been input.
If this step is affirmed, or step S5
If a predetermined end process (coordinate input to the predetermined area (not shown) by the input pen 23) is performed in 10, the process ends. If the process is not completed, the counter N is incremented in step S511 and the process returns to step S502.

6 and 7 show the input and recognition processing of the decoration information. The flow of recognition processing of the modification information is almost the same as that in the case of character recognition. Character modification input area 32
The input is made by handwriting as described above. Here, the underline and the modification by the mark point are illustrated.

That is, single line, double line, broken line, wavy line,
When modifying a mark point, a white circle mark point, or the like, each pattern is input by handwriting with the input pen 23, as shown from the top on the left side of FIG. This makes CP
The U10 recognizes the input decoration pattern, and performs an orderly decoration display in the character decoration input area 32 using a corresponding font as shown on the right side of FIG.

FIG. 7 shows a procedure for recognizing the decoration information by the CPU 10 (processing of step S506 of FIG. 5).
First, in step S701, a series of strokes is input by the input pen 23. This input is step S
In any one of 702, S703, and S704, the operation is performed until no input for a certain time or more, or a predetermined ending operation or an input to the outside of the area is confirmed, and the stroke input during that time becomes the modification information.

In step S705, the number of strokes and starting point coordinates are determined, and in step S706 the input stroke data is converted into a plurality of vector data along a predetermined direction.

In step S707, the strokes are grouped in advance according to the number of strokes and matching with the modification information stored in the ROM 11 is performed. In step S708, the best matching pattern is selected and the final modification pattern is recognized. This result is stored as attribute information for the corresponding character in the memory RAM 12.

By such a procedure, the handwriting input of single line, double line, broken line, wavy line, mark point, white circle mark point, etc. in the character modification input area 32 enables modification. According to the above-described embodiment, the modification information may be entered by handwriting, and since it is not necessary to perform the mode-dependent input as in the conventional case, the operation is easy,
Moreover, learning is extremely easy.

Further, since the character input area 31 and the character modification input area 32 are partitioned, it is possible to easily identify the character / modification information input in the respective input areas, and the CPU 1
The recognition process by 0 can be performed very easily.

In the above embodiment, the five character input areas 3
An example of inputting a character and modification information of the character for each of the character modification input area 1 and the character modification input area 32 has been shown. However, character input and modification information input should be performed in an appropriate number at a time. Good.

FIG. 8 and FIG. 9 show the procedure in this case in detail. FIG. 8 shows the same control procedure as in FIG. 5, and the same steps as those in FIG. 5 are designated by the same step numbers, and detailed description thereof will be omitted. The difference from FIG. 5 is the positions of step S510, step S509, and step S511.
That is, in step S 505, it is determined whether the input of the input pen 23 is to the character modification input area 32 or the character input area 31, and thus the step S 5
06, S503, S504, S507 and S508, character and modification information recognition and output processing, or other character input processing is selected. That is, when the modification information is input, the character information and the modification information input so far are recognized and output. In the recognition of the modification information in step S506, a plurality of modification information input areas 3
It is assumed that the recognition of 2 is performed by the procedure of FIG.

By such control, for example, after inputting a character in one or all of the character input areas 31, it is possible to input the decoration information in the necessary (one or more) character decoration input areas 32. Becomes The example of FIG. 9 is 91, 9
Characters and modification information are input in the order of 2 ... 95, 96, 97. That is, the character string "Akatokuro" (91-9
After inputting 5) "Aka" (96) and "Kuro"
An underline and a double sideline are drawn in the part (97).

In the above embodiments, an example in which the modification is performed on the display is shown, but it goes without saying that the modification may also specify the modification at the time of print output. Further, needless to say, the present invention can be applied not only to characters but also to modifications such as graphics.

Further, both the character information and the modification information are
It is also possible to input at arbitrary timings and to recognize each when the input for one area is completed.

The above-described modification information such as underlines and side dots is merely an example, and it goes without saying that the present invention can be implemented when other modification information is input. Further, the character input area 31 and the character modified input area 32 may be distinguished from each other as the input area, and the characters or the modified display may not always be displayed in the same frame.
For example, it is conceivable that a character on the character input area 31 is shaded by inputting a shade or the like in the character modification input area 32.

A mouse or the like may be used as the coordinate input means, and the coordinate input means does not necessarily have to be stacked on the display means.

[0040]

As is apparent from the above, according to the present invention, the coordinate input means and the data input area in which the coordinate input is possible are provided on the coordinate input means, and the data input into the data input area is provided. In an information processing device for displaying data in the data input area based on a pattern, the data input area is divided into a first input area and a second input area, and based on a data pattern input in the first input area. In addition to displaying the data, the modification display for the data pattern displayed in the first input area is performed based on the data pattern input in the second input area. It is possible to provide an excellent information processing device that allows extremely easy input.
