Abstract

PURPOSE:To easily add a character pattern to a part of document image data with no addition of an original document, by providing a document memory, a character pattern memory and a rewriting means. CONSTITUTION:When a character pattern like a title, a comment, etc. is added to a part of the document image data, a specific position where the characters are added is designated on a CRT 3. Then the position of a cursor is informed to a position calculation means 14a via a CPU 1 with push of the button of a mouse 4. Thus the positions, etc. are calculated within a document memory 12, a video RAM 13 and informed to a character adding means 14b. The additional characters are designated by a typewriter keyboard 2 and the means 14b reads a character pattern corresponding to the designated character codes out of a character pattern memory 11 every time a single character is designated. Then the read-out pattern is transferred onto the prescribed positions of the memory 12 and the RAM 13 respectively. Thus it is possible to easily add the character pattern with no addition of an original document.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document image processing device that electronically processes one document as image data.

[Prior Art] In a conventional document image processing device, when an image is read by its input unit and stored in an external storage device such as an optical disk,
When displaying scanned image data on the display,
If you want to add a character pattern such as a title or comment to a part of the displayed document image data, follow the steps 1 and 2.
There are two ways.

The first method is to have the worker directly handwrite the character pattern such as the title or comment that they want to add into the original document (the document before it is registered in memory as image data), and then add this added document by hand. This is a method to read optically.

The second method is to first optically input the original document and then store it. Then, input and memorize a predetermined document with characters such as a title or comment that you want to add, extract only the necessary character strings from the image data of this document, and create a 1-inch image of the above text that you have already memorized. Convert it into data.

However, the conventional method of 1.1 leaves additional characters in the original document itself. The problem is that it is inconvenient if you don't want to use it. Furthermore, the second conventional method has a problem in that the entire operation is complicated because the document including the character pattern must be input again.

In addition to this, additional characters can be stored as code data and added to the pattern data when outputting. Sentence: j; It is conceivable to add it to the image data, but this would complicate the configuration and operation of the device, and it would be necessary to store the image data and code data together on the optical disk, resulting in bit errors. There is a problem in that it is difficult to store mixed information on an optical disc with a low rate.

1 shot 11 [j-target] The present invention was made based on the problem of the L-registered example [1], and it adds a character pattern such as a title or a comment to a part of document image data. One object of the present invention is to provide a document image processing bag that does not require any additions to the original document and can easily add a single character pattern.

1 shot 1 jl embodiment] FIG. 2 is a system block diagram showing an embodiment of the present invention.

This embodiment performs the main 118 of the system and R
It has a central processing unit (CPU) 1 having an AM or ROM, a typewriter keyboard 2 for inputting character data or function signals, and a CRT 3 of a rask scan display type. In addition, CR
T3 uses high resolution to display sufficient information.

The system described in - also includes a mouse 4 as a pointing device that is used for specifying the upper part of the display screen,
An image reader 5 for inputting images, an optical storage device 6 that can only be read once but can store a large amount of document image data, and a disk 7 that stores character pattern information stored in character image T-dot format. , and an image printer 8 for printing high-quality documents. These components are connected by an I10 bus 9 of the CPUI.

FIG. 1 is a brochure diagram showing the above embodiment more specifically. Note that the members shown in FIG. 2 and the members of the circuit are the same and are designated by the reference numeral f-1.

In FIG. 1, the main memory of the CPU is divided into three parts: a character pattern memory 11, a document memory 12, and a video RAM 13. In other words, a predetermined number of character patterns are arranged in the character pattern memory 11 in the order of their character codes.When a character code is specified, the first address of the character pattern is stored. For example, addresses 128, 256, i
At address ooa, the characters rQJ, "1", and "A" are stored in a bit pattern, respectively.

The document memory 12 stores document image data, and stores the text and image data read by the image reader 5 or the document image data sent from the optical disc 6. The Bunshi image f-Yu inputted from the image reader 5 and stored on the optical disk 6 always passes through the document memory 12. The contents of the document memory 12 are also stored in a bit pattern in the video RAM! 3 is for storing the display f-event immediately before displaying the image data/event on the CRT 3. Also in the video RAM 13, display contents are stored in a pattern of B, ). For example, video RAM1
Bee with 31 symbols.

If the bit is "1", the C RT corresponding to that bit is
If the bit stored in the video RAM 13 is "0", then black is displayed at the position 3, and white is displayed at the position of the CRT 3 corresponding to that bit. Therefore, if the contents of the video RAM 13 are changed, the contents displayed on the CRT 3 will be changed.

Rewriting-L stage 14 is sentence-I? Some of the image data of
This is used to rewrite image data of a character pattern, and is composed of an a-replacement position calculation means 14a and a character addition means 14b.

The rewrite level calculating means 14a calculates the rewriting level by using the CRT for adding characters.
This is to calculate which position in the document memory 12 and the video RAM 1S the position specified on Z corresponds to.

The character adding means 14b reads the character pattern corresponding to the character input from the typewriter keyboard 2 from the character pattern memory 11, and t) the replacement position calculation means 14.
In document memory 12 and video R calculated by a
This control controls enlarging and then transferring the read character pattern to the position in AM13.

Note that reference numerals 15 and 16 indicate switching means for switching information from peripheral equipment.

As described above, the CPUI handles characters or graphics on a bit-by-bit basis, but it is also capable of processing enlargement, reduction, rotation, and movement of characters or graphics.

Next, the operation of the above embodiment will be explained.

FIG. 3 is a flowchart for the above embodiment.

First, upon request by operating the typewriter keyboard 2,
A document is read from the image reader 5, and the document data is stored as image information in the document memory 12 (
SPY), here rsPJ represents a step, and the same applies hereafter.0 Transfer the image data written into the document memory 12 to the video RAM 13, and display the document on the CRT 3 (SI'2), Document memory 12 The number of pixels in the video R
Since the ratio of the number of pixels in AM13 differs depending on the resolution at the time of reading by image reader 5, document memory 12
When transferring the contents to the video RAM 13, pixels in the memory are thinned out at an appropriate reduction rate using a known method.

Next, select where to add the characters in the document using C
RT] h (SF3), a map and a national flag are shown in the 4th IA, and the map and the national flag are stored as image data in the document memory 12 and the video RAM 13, as shown in FIG. Assume that the position of the character to be added is specified in the area surrounded by the dotted line. In this case, C
Using the mouse 4, specify with a cursor the left I-, part a and the lower right part of the rectangle corresponding to the dotted line position on the screen-L of RT3. In other words, the cursor moves on the display screen of the CRT 3 as the mouse 4 moves.
Move the cursor to the upper left a of the rectangle and press the mouse 4 button, move the cursor to the lower right a of the rectangle, and press the mouse 4 button again.

When you press button 4 on mouse 4, typewriter keyboard 2
An input signal is sent to the CPUI via the CPU. The CPU 1 notifies the rewrite position calculation means 14a of the position of the cursor displayed on the CRT 3 when the button is pressed. The rewriting position calculation means 14a calculates which position in the document memory 12 and video RAM 13 the broken line area shown in FIG. The character addition means L4b is informed of the digit t, height, and width.

And what characters should be added to the typewriter keyboard?
(SF3), each time a character is designated, the character adding means 14b reads the character pattern corresponding to the designated character code from the character pattern memory 11, and adds the character code to the sentence S.
The image is enlarged to a position corresponding to a rectangle in the memory 12 and the video RAM 13 (dotted line area I7 shown in FIG. 4) and then transferred. That is, in the document memory 12 and in the video RAM 13.
Write the characters added inside as an image.

The operation of SF3 is repeated until the character pattern is filled within the rectangle.

FIG. 5 shows an example in which characters are displayed in the broken line area of FIG. 4.

Next, make! A new document with one character added to the name is saved as is in the optical disk device 6 (SF3). in this case,
The new document may be printed out using the image printer 8.

Above, SP1~5? By repeating this process, you can easily add characters to the document read by the image reader 5.
By repeating steps P3 and P4, characters can be added to multiple locations within the document.

Instead of the mouse 4 as a pointing device, you may use a light pen or keys on a typewriter keyboard 3. In addition to alphanumeric characters, katakana, and hiragana, you may also use kanji as additional characters. So S. When using kanji as additional characters, a kanji conversion means for converting roman characters or katakame into kanji may be incorporated in the input 1 from the Thai keyboard 2.

In addition, in Example J-1, an optical disk that can be recorded only once was used in the human scale disk device.
Of course, a rewritable magneto-optical disk may also be used.

[Effects of the Invention] The present invention does not require any additions to the original document when adding a character pattern such as a title or comment to a part of one document image data, and the character pattern can be easily added. 8 to have the effect of being able to
