Abstract

PURPOSE:To easily superpose a character, etc., on an image by providing a contour extracting means. CONSTITUTION:A rewriting control device 5 is constituted of a microprocessor, and has a function for rewriting the contents of a video RAM 6 and a function for converting a character code to a character dot pattern. A contour data is extracted by the rewriting control device 5. A character data from a keyboard 8 is stored in a document memory 2 through an I/O interface 11 and a bus, and a printer 9 is a dot printer of an impact type, and outputs a dot pattern data which is sent through an image bus and the I/O interface 11. Even when extracting a contour, (a)-(e) denote one dot in an image data, and a' denotes one dot in the contour data of a position corresponding to a point (a) in the image data. As for a transfer, when (a)-(e) are all '1', a' becomes '0', and in case of other time, (a) is transferred to a' as it is.

Description

DETAILED DESCRIPTION OF THE INVENTION [(Already required)] A document processing device that reduces the density of black by extracting the outline of image data and facilitates composition with sentence 9.

[Industrial application field]

The present invention relates to a document processing device having a function of extracting contour data from image data and a function of synthesizing the extracted contour data and document data.

[Prior art and problems]

In recent years, word processors and the like have been provided with the ability to insert image data from an image scanner or the like into a portion of a document. However, when output devices such as dot printers, which are often used in word processors, output dense black data, the ink ribbon gets tired and blurring occurs, making it impossible to obtain clear output. It has this characteristic. Furthermore, even if characters are superimposed on densely black areas of image data, they become unreadable. To solve these problems, it is necessary to reduce the black density of the image data without destroying its original form.

[Purpose of the invention]

The present invention is based on the above-mentioned idea, and by providing the document processing bag 1 with an outline extraction means, it is possible to obtain data that satisfies the above-mentioned needs, and to convert an image such as a photograph into a line drawing. It is an object of the present invention to provide a document processing device that can easily realize an expression method such as combining a document with a document.

[Means to achieve the purpose]

Therefore, the document processing device of the present invention includes means for inputting document data, means for inputting image data, means for extracting contour data from the inputted image data, and a means for inputting the extracted contour data and the inputted image data. The present invention is characterized in that it includes at least means for synthesizing document data, means for displaying the synthesized data, and means for outputting the synthesized data.

FIG. 4 is a diagram showing input of image data. Image data input from the image scanner IO is stored in the video RAM 6 via the I10 interface 11 and the image bus.

FIG. 5 is a diagram illustrating extraction of contour data.

The image data read from the video RAM 6 is sent to the rewriting control device 5, which extracts contour data, and the resulting contour data is stored in the video RAM 6 again.

FIG. 6 is a diagram illustrating the composition and display of contour data and document data. The document data is converted into dot matrix format document data by the rewriting control device 5,
It is written into the video RAM 6. Outline extraction of the image data in the video RAM 6 is performed by the rewrite control device 5, the sentence 2 data in the dot matrix format and the outline data are combined, and the combined data is written into the video RAM 6. The composite data in video RAM6 is CRT
displayed on the display 7.

The composite data extracted from the video RAM 6 is sent to the printer 9 via the image controller 10 interface 11, and is output by the printer 9.

Next, the operation when using the document processing apparatus shown in FIG. 1 will be explained. The document processing device shown in FIG. 1 inputs commands from the keyboard 8 (command string input using character keys or
It is operated by entering each command mode by pressing a key (pressing a key) and performing a series of operations corresponding to that command. The command mode includes modes such as sentence S input, image input, image composition, and document output. The operation of each command will be briefly described below.

Document Input> A document input command causes the document processing device to enter document input mode. In the document input mode, character strings input from the keyboard 8 are displayed on the display 7 and stored in the document memory 2. You can also delete, cursor,
By pressing a special key such as the key, you can delete previously input characters or specify the input position.

Image input> By inputting an image input command, the document processing device enters the image input mode. In the image input mode, parameters necessary for reading, such as the size of the input image, can be set similarly to command input. Further, image data is read from the image scanner 10 according to the parameters set by the read start command.

Image compositing> By inputting the image compositing command, the document processing device enters the image compositing mode. The image composition mode is operated by the following four types of subcommands.

(al　Composition range specification (bl　Composite image specification (C) Contour extraction (d) Synthesis execution Each subcommand will be described below.

tal Synthesis range specification By inputting the synthesis range specification subcommand, the input document is displayed on the display 7.

Use the cursor and the execution key to indicate the diagonal line of the rectangle that indicates the range in which the images will be combined. (Specify one point by moving the cursor and pressing the execution key. This is done at both end points of the diagonal line) to specify the synthesis range.

(bl Composite image specification Composite image specification By inputting the subcommand, the input image data is displayed on the display 7. By pressing the cursor key and the execution key,
Points to the lower left corner of the rectangle that represents the image area. (Specify one point by moving the cursor and pressing the execution key.) This specifies the rectangle of the image to be synthesized. (The size is indicated by the synthesis range specification.) fcl Contour extraction By inputting the contour extraction subcommand, the contours of the image data to be synthesized are extracted before synthesis. (163VI extraction is not performed if this command is not input.) (d) Synthesis execution By inputting the composition execution subcommand, the image and sentence S are synthesized according to the conditions set by the above three types of subcommands. .

Document Output> The document processing device enters document output mode by inputting a document output command. In the document output mode, parameters necessary for output such as the size of the output document can be set in the same way as command input. Further, the text is output by the printer 9 in a format according to the parameters set by the output start command.
