Abstract

PURPOSE:To confirm whether or not an original sentence is correctly converted into character codes in a quick and accurate way, by displaying the images of handwritten characters on the 1st line of a screen and the character codes converted from the 1st line on the 2nd line, respectively. CONSTITUTION:A handwritten sentence supplied from an image input interface circuit 3a is stored to a display controlling circuit 2 containing a buffer memory and a display controller and then displayed on an odd character line of a display 1 in an analogous form of the handwritten characters after image control including a line feed, etc. This displayed sentence is visually confirmed, and a keyboard 5 is operated on the basis of the displayed sentence. Then the character code is fed to be stored in the circuit 2. These character codes are displayed successively on the even character lines of the display 1 with control.

Description

[Detailed Description of the Invention] (Technical Field) The present invention enables handwritten text to be completely human-generated.
The present invention relates to a character display method for a document input/output device that can quickly and accurately convert text into character coded text.

(Background Art) A conventional keyboard display device is shown in Figure 1. In Figure 1, 41 is a display, 2 is a display control circuit, 3 is a simple digitizer terminal, 4 is a computer interface circuit, 5 is a keyboard, and 6 is a cursor The instruction terminal 7 is configured like a printer terminal. Characters input from the keyboard 5 (including alphanumeric characters, kana, hiragana, and kanji) and information from the computer output input to the keyboard display device via the computer interface circuit 4 are sent to a predetermined number designated by the cursor pointing terminal 6. The display character line, the string will be displayed. On the other hand, in the case of online handwritten figures inputted from the simple digitizer terminal 3, the entire surface of the digitizer corresponds to the entire surface of the display, and the figure is drawn while looking at the display screen rather than specifying by character lines or strings.

Therefore, in conventional keyboard display devices, image codes are handled in the range of online handwritten figures, and separately created handwritten text is input as characters using image codes, and then the characters are displayed as characters on the display.
It does not have a function to display in response to strings,
In addition, it has the disadvantage that it does not have a display control function that allows characters based on image codes and characters based on character codes of the same sentence to be displayed on the same display in contrast.

(Problems to be solved by the invention) In order to solve these drawbacks, the purpose of the present invention is to display on the same display a handwritten text that is an original text and a text that has been character-coded manually or a text that has been character-coded using a character recognition device. These are shown in comparison and will be described in detail below.

(Structure and operation of the invention) FIG. 2 shows an embodiment of the invention, in which 1 is a display;
2 is a display control circuit, 2-1 is an odd character line control,
2-2 is an even character line control, 3a is an image input interface circuit, 4 is a computer interface circuit, 5 is a keyboard, 6 is a cursor instruction terminal, and 7 is a printer terminal.

The handwritten text input from the image input interface circuit 3a is stored in a display control circuit 2 consisting of a buffer memory and a display control, and is subjected to image control such as line breaks and displayed in odd-numbered character lines on the display 1 in a similar form to the handwritten text. Ru.

When you visually check the displayed text and enter a character code by pressing keys on the keyboard 5, the character code is stored in the display control circuit 2 consisting of a buffer memory, a character generator, and a display control, and is controlled and displayed on the display. They are displayed sequentially in the 1st even numbered character row.

In this case, the display control circuit 2 decodes commands from the keyboard 5 and controls the characters in the odd-numbered rows and the characters in the even-numbered rows below them. To check whether the handwritten text has been converted to the correct character code, visually compare the corresponding odd-numbered character lines and even-numbered character lines, and if there is a difference, point it out using the cursor instruction terminal 6, The correct character code is corrected by inputting the correct character code from the keyboard 5, and the character code thus created correctly is outputted from the display control circuit 2 to the computer or the like via the computer interface circuit 4.

If a hard copy is required, the display control circuit 2 decodes the command from the keyboard 5 and outputs the contents of the display 1 to the printer 7.

Another operation is that the handwritten text manually entered by the image input interface circuit 3ai is displayed on the odd character rows of the display l as described above, while the same handwritten text is automatically converted into a character code via the character recognition device. may be input from the computer interface circuit 4. These character codes are accumulated in the display control circuit 2 and displayed on even-numbered character lines by the display control. Whether or not the automatically converted character code is complete is determined by the same operations as described above for the operations after verification.

As explained above, the embodiment has an image human interface circuit and a computer interface circuit, and can be connected to a facsimile terminal, facsimile exchange, character recognition device, or computer. Even if handwritten sentences are created or characters are recognized in the middle of the day, there is an advantage that these can be centrally input into this device via a line. In addition, as a method of converting the complete character code text obtained by this device into a six-dimensional character code that can be output to a computer for further various processing, the handwritten image code text displayed on the display is used. The result of typing the keys on the keyboard is converted into a character code and displayed, and the original handwritten image code text is converted into a character code within the range permitted by the recognition rate through a character recognition device. Since it has a means for inputting and displaying it on a display, it has the advantage of being able to use the appropriate method depending on the complexity of the original text. Furthermore, as a display display method, the original handwritten image code text and the text converted to character code are displayed in adjacent character lines on the same display, so visual comparison can confirm that the original text has the correct character code. The advantage is that you can easily, quickly and accurately check whether the conversion has been made. If there is an error, you can point it out using the cursor pointing terminal, enter the +EL character code from the keyboard, and make corrections by looking at the display until the content is the same as the original.

In particular, when using a character recognition device, the current character recognition rate is not 100% due to technical difficulties, and there is an advantage as a complementary function device that requires manual intervention.

(Effect of the invention) For example, in an office, when converting old sentences created by each person in charge into complete character code sentences by hand via a local network at a word processing center or centrally at each workplace, conversion is possible. It can be used as a functional document input/output device. The advantage of always handling text in character code is that compared to image information of handwritten text, it requires less memory capacity for storage, makes editing easier, and improves transmission speed. It is particularly effective in realizing office automation from the aspect of document processing, as it speeds up processing.
