Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handwriting table recognition apparatus capable of recognizing a freehand written table structure and drawing it on a display.

[0002]

2. Description of the Related Art Conventionally, when creating an arbitrary table format, a desired table format has been created by combining arbitrary ruled lines on a display while operating a keyboard in a personal computer system. For example, as shown in FIG. 4, a personal computer 101 is used, a keyboard 102 and table creation software 103 are used, and an arbitrary ruled line is drawn on the screen of the display 104 to create a table. The drawing direction of the ruled line is the keyboard 1
The cursor 106 is moved by designating with the direction designation key 105 of 02, and the tables are sequentially created.

[0003]

However, in the above-described conventional table creating method, a personal computer system is used, and the operator creates a table by combining ruled line data by manual operation, so that a complicated table format is created. In that case, there was a problem that it was inefficient and took a lot of time.

The present invention solves such a conventional problem, and an object of the present invention is to provide a handwriting table recognition apparatus capable of efficiently creating a complicated table format.

[0005]

In order to achieve the above object, the present invention provides an image for reading handwritten table data in which the line spacing and digit spacing required for each cell of a table constituted by ruled lines are described by numbers. The reader, the table recognition means for recognizing the cell structure of the table in the handwritten table data, the character recognition means for recognizing the numbers in the handwritten table data, and the table structure according to the recognized table cell structure and numbers. It is provided with a table creating / editing means for creating, and an operating section and a display section for creating the table structure while displaying it on the screen.

[0006]

According to the present invention, when the image reader reads the table data created by the operator by the above configuration,
The table recognition means and the character recognition means analyze the table structure and the ruled line intervals represented by numbers, and the table creation / editing means displays the table structure on the screen of the display unit. Can be created easily.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an embodiment of the present invention. In FIG. 1, reference numeral 1 is handwritten table data created by an operator with a pencil or a ruler, 2 is an image reader for reading the handwritten table data 1, 3 is an external interface for connecting the image reader 2, 4 Is a CPU for controlling the entire apparatus, and 5 is an image reader 2
An image memory for storing the image data read by, 6 is a system program, 7 is table recognition software,
8 is character recognition software, 9 is table creation / editing software, 10 is a keyboard, 11 is a keyboard control unit, 12 is a display unit such as a CRT, 13 is a display unit control unit, and 14 is a system bus that connects the CPU 4 and each unit. .

Next, the operation of the above embodiment will be described with reference to the flow chart shown in FIG. 2 and the schematic diagram shown in FIG. First, handwriting table data 1 with a pencil, ruler, etc.
Is created (step 21). This handwriting table data is
The cells are formed by ruled lines such as vertical and horizontal lines, and numbers indicating the line spacing and the digit spacing are entered in each cell. Next, the handwriting table data 1 is read by the image reader 2 (step 22), and the read image data is stored in the image memory 5 via the external interface 3 (step 23). Next, the cell structure in the image data read using the table recognition software 7 is analyzed (step 24), and then the numbers in the cells are analyzed using the character recognition software 8 (step 25), and the table creation / editing software is used. 9 is used to create a table structure according to the numbers in each cell (step 26), and is drawn on the screen of the display unit 12 (step 2).
7). Next, it is compared whether or not the table displayed on the screen is the same as the original image (step 28), and if there is a correction, the direction designation key 15 of the keyboard 10 is used to move the cursor 16 on the display unit 12 The table structure is moved to correct the table structure (step 29). If there is no correction, the table structure is registered in the image memory 5 and the process ends (step 30).

As described above, according to the above embodiment, the handwriting table data 1 written with a pencil and a ruler is read by the image reader 2 and the table recognition software 7 and the character recognition software 8 are used from the image data. Since the table structure and the intervals between the ruled lines are calculated and the table is created while being displayed on the screen of the display unit 12 by the table creation / editing software 9, even a complicated table can be easily created in a short time.

[0010]

As described above, according to the present invention, an image reader for reading handwritten table data in which the line spacing and digit spacing required for each cell of a table constituted by ruled lines are described by numbers, and handwriting Table recognition means for recognizing the cell structure of the table in the table data, character recognition means for recognizing the numbers in the handwritten table data, and a table for creating the table structure according to the recognized table cell structure and numbers. Creating and editing means,
Since a table structure is provided with an operation unit and a display unit for displaying it on the screen, it is possible to easily create a complicated table in a short time.
