Abstract

PURPOSE:To put freely the complicated graphics like illustrations, photos, etc. into a document produced with input of character codes, by registering the image data read through an image reading part in the form of a dot pattern. CONSTITUTION:A reading command is produced from a display input part 14 after both originals A and B are set to an image reading part 11. The part 11 reads the originals A and B and quantizes them to produce the image data containing image pattern. This image data is delivered to a data processing part 12. The part 12 stores the image data on the original A into a memory part 13. Then the part 12 discriminates three enclosing frames 201-203 added to the original B by a pattern matching method for the image data on the original A stored in the part 13 and the image data on the original B received from a part 11. These recognized frames 201-203 are registered in the image data register areas in the part 13.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an image processing method used in the field of information processing systems, and particularly to an image processing method suitable for processing documents containing graphics. be.

2. Description of the Related Art In word processors, which are currently becoming popular as part of office automation, documents are created by sequentially inputting character codes by pressing predetermined keys.

In addition to such a document creation function, word processors equipped with a graphic creation function are also becoming popular.

When trying to insert a figure into a document using such a word processor, the document mode is first switched to figure mode, and the drawing command that specifies the type of figure to be drawn, such as a straight line, dotted line, rectangle, or circle, and the cursor are used to draw the figure on the screen. Drawing is performed by specifying the position.

Problems to be Solved by the Invention When attempting to draw with the above conventional word processor,
Since it requires complicated operations such as switching to figure mode, inputting drawing commands, and moving the cursor, there is also the problem of slow drawing speed.

There are devices that add image processing functions to word processors that allow you to insert or delete figures in a document, but these editing processes are performed using a combination of a display device such as a CRT display and a light pen. This also has the problem of taking time and effort to process.

Another problem is that conventional word processors cannot create manuscripts with illustrations or photographs because they can only draw relatively simple figures such as combinations of straight lines, rectangles, and circles.

Means for Solving the Problems of the Structure of the Invention The image processing method of the present invention that solves the problems of the above-mentioned prior art includes: (1) reading a first document in which figures that may include characters and symbols are displayed; , the first by quantizing and dot pattern.
(II) read a second document with an indication specifying the range of image data to be registered in the first document, quantize it, and create a second image data in a dot pattern; Create image data (
III) Identify the range of image data to be registered by comparing these first and second image data, add an identification code to the identified range of image data and register it in the storage unit, (rV) identify the identification code. By specifying, the corresponding registered image data is successively retrieved from the storage unit and inserted into the specified location in the document being created by pressing a key, thereby allowing the image data of the dot pattern display to be inserted at any time in any location in the document. , is configured to easily and quickly create documents containing figures.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

Embodiment FIG. 1 is a functional block diagram showing the configuration of an image processor to which an image processing method according to an embodiment of the present invention is applied.

This image processor includes an image reading section 11, a data processing section 12, a storage section 13, a display/input section 4, and an image printer 15.

The image reading section 11 is equipped with a -dimensional sensor or a two-dimensional sensor, and scans the image on the document placed on the document table to create dot pattern image information by quantizing the image. Pass it to I2.

FIGS. 2A and 2B are examples of documents read by the image reading section 11 when registering image data.

The document (A) displays a document or a figure including a picture or photograph, but these are not shown because they may be arbitrary.

Manuscript (B) has exactly the same documents and figures as manuscript (A),
A frame 2 drawn with a writing instrument such as a pencil or ballpoint pen to indicate the designated registration location of image data in the manuscript (A)
01.202 and 203 are added.

First, after the original (A) in FIG. 2 is set on the image reading section 11, a reading command is issued from the display input section 14. The image reading section 11 reads the original (A) and quantizes it to create image data based on the dot pattern, and passes it to the data processing section 12 . The data processing unit 12 stores the image data of the received document (A) in the storage unit 13.

Next, after the original (B) in FIG. 2 is set in the image reading section 11, a registration command is issued from the display input section 14. The image reading section 11 reads the document (B) and quantizes it to create image data based on the dot pattern, and passes it to the data processing section 12 .

The data processing unit 12 processes the original document previously stored in the storage unit 13 (
The image data of A) and the image data of the document (B) received from the image reading unit 11 are added to the document (B) using a pattern matching method in which an exclusive OR is performed for each dot at the same screen position. The three enclosed frames 201 to 203 are identified.

The data processing unit 12 extracts the image data based on the dot patterns included in the three identified enclosure frames 210 to 203, assigns a registration number and an identification code indicating that it is a dot pattern to each image data, and stores the image data in the storage unit 13. Register in the image data registration area within.

This registration process is extremely easily performed by firmware processing.

Each registered image data is assigned a corresponding registration number (FPO5) as illustrated in FIG.
), CFPO6), etc. as well as the CRT of the display/input section 14.
It is output on the screen or to the image printer 15 for confirmation.

FIG. 4 is a conceptual diagram illustrating a screen displayed on the CRT of the display/input section 14 when creating a document containing graphics after registering image data.

In FIG. 4, a box 401 indicates a document editing area.

On the left side of this box, the registration number (FPO7) of the image data to be inserted into the document created by inputting the character code by pressing the key is input from the keyboard.Subsequently, the upper left corner of the insertion position of the image data is , is specified by the cursor position (+), and then the execution key is pressed.

The data processing unit 12, which has received this registered image data insertion command, reads out the image data corresponding to the registration number (FPO7) from the image data registration area in the storage unit 13, and specifies it by the cursor position in a well-known screen memory (not shown). Insert this image data at the insertion position specified.

The data processing unit 12 adds, as part of the display control information, an appropriate display to the effect that image data to be displayed as a do-no-do pattern exists in the insertion area of this image data, instead of a character code entered by a key. do. The image data inserted into the screen memory is directly converted to CR without going through a well-known code/pattern converter (not shown).
, T and displayed.

A document is created using the character code input from the keyboard in the blank space on the screen excluding the place where image data is inserted. The character code is stored as code information in the screen memory, converted into a dot pattern in the code/pattern conversion memory, and then output to the CRT for display.

By mixing the insertion of such registered image data with the input of character codes from the keyboard, a document containing figures is created. The created document is printed out by the image printer 15 or stored in the storage unit 13.

Above, we have shown an example of a configuration in which the registration target part of the image data in the manuscript is specified using a surrounding frame. However, for the registration target area such as a rectangle, you can add a cross mark to two diagonal points, or register a polygon. The area can also be specified by other appropriate methods, such as by marking only the vertex positions.

In addition, although the configuration in which the keyboard is used as an input device is illustrated,
The input device may also be a combination of a CRT and a light pen. .

Effects of the Invention As explained in detail above, the image processing method of the present invention is configured to register the image data read by the image reading section as a dot pattern, so input processing of figures etc. becomes easy and quick. Another advantage is that complex figures such as illustrations and photographs can be freely inserted into documents created by inputting character codes.

In addition, the image processing method of the present invention is configured to automatically identify the registration range by pattern matching between the original document and the document with the registration range specification added, making the graphic input operation extremely simple. The effect is also produced.
