Abstract

PURPOSE:To simplify a picture processing system by allotting a proper code that has no overlap with a character code or other control code to each word of a picture memory storing picture information and processing picture for each word as well as the character code. CONSTITUTION:Both character and control codes are supplied successively to a character code memory 13 from an input part 10. At the same time, the designated coordinates of a picture synthetic area are fed to a coordinate table 14. The picture information is fed to a picture memory 15 from an input part 11. The contents of the memory 13 are copied to a code memory 17. The picture code of each word of the memory 15 corresponding to the picture synthetic area designated by the table 14 is read out of a conversion table 16 by a synthetic circuit 18 and written to the picture synthetic area of the memory 17. A code bit conversion part 19 reads the memory 17. The information on character and picture are read out of a character font memory 12 and the memory 15 and developed to a bit image memory 19 and then displayed to a CRT21. This simplifies both method and the device for the picture processing.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an image processing method in a wort processor or the like.

Structure of a conventional example and its problems FIG. 1 is a schematic block diagram for explaining an image processing method in a conventional word processor.

In this figure, 1 is a code input section consisting of a keyboard for inputting character codes, control codes, etc.;
is an image input section consisting of a skip for inputting images. 3 is a character font memory that stores character font data.

4 is a character code memory for storing the character code string of the document. 5 is an image coordinate table; 6 is an image memory for storing image information; and 7 is a code/bit conversion unit that develops one page of document image in the bit image memory 8. 9 is a CRT display unit.

Next, the operation when creating a document including images will be explained. The character codes are sequentially input into the character code memory 4 from the code input section 1, a document consisting only of characters is created in the character code input section 4, and the image information (human image) to be combined with the document is input from the image input section 2. Input to image memory 6. Coordinate information specifying an image compositing area on the document is input from the size code input unit 1 into the coordinate table 6. The code/bit conversion unit 7 reads a character code from the character code memory 4, reads character font data (bit image) corresponding to the character code from the character font memory 3, and writes it into the bit image memory 8. It's a size.
The image information read from the image memory 6 is written into an image compositing area on the visual image memory 8 specified by the coordinate information stored in the coordinate table 5. A bit image of one page of Japanese text, which is obtained by combining the images in this manner, is developed on the bit image memory 8 and displayed on the CRT display units 1 and 9.

As is clear from the explanations in J and l below, conventionally characters are handled in units of words, whereas images are handled in units of bits, and editing of images combined with documents is done in the image memory 6. Must be processed by bit manipulation. The problem with such a method is that it complicates the word processor program and hardware such as the code/bit converter 7, making the word processor more expensive.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and an object thereof is to provide an image processing method that can inexpensively realize a word processor or the like having an image processing function.

Structure of the Invention - The present invention assigns a unique image code that does not overlap with character codes or other control codes to each word of an image memory for storing image information, and processes the image using this image code. By doing this on a word-by-word basis in the same way as on characters, the purpose stated above is achieved.

Description of examples Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a schematic block diagram illustrating a word processor according to one embodiment of the present invention. In this figure, 1Q is a code input section consisting of a guitar board or the like for inputting character codes and control codes. Reference numeral 11 denotes an image input section consisting of a scanner or the like for inputting image information. 12 is a character font memory that stores character font data, 13 is a character code memory that stores the character code string of the document, and 14 is a coordinate table that stores coordinate information that specifies the image synthesis area of the document. be. 16 is an image memory that stores image information. This image memory 15 is a memory that can be accessed in units of words, and a unique image code is assigned to each word. 16 is a conversion table in which image codes of the image memory 16 are registered. Reference numeral 17 is a code memory for storing code data of one page of document, and reference numeral 18 is a synthesis circuit for synthesizing image data consisting of image codes on the code memory. A bit image memory is used to store a bit image of one page of a document, and 20 is a code/bit conversion unit that converts a character code or image code into a bit image. 21 is a CRT display unit.

Next, the operation will be explained. The character codes of the document are sequentially input into the character code memory 13 from the code input unit 10, and the coordinate information specifying the image synthesis area of the large document is stored in the coordinate table 1.
4 is input. Image information is input from the image input section 11 to the image memory 15. The stored contents of the character code memory 13 are copied to the code memory 17. Coordinate table 1
The image code of each word of the image memory 15 corresponding to the image synthesis area specified by the coordinate information set to 4 is read from the conversion table 16 by the synthesis grain 18,
The data are sequentially written into the image synthesis area of the code memory 17.

In this way, the code data of the document obtained by combining the images is obtained in the code memory 17.

The code/bit conversion unit 20 sequentially reads the code data in the code memory 17, converts the character code into corresponding character font data by accessing the character font memory 12, and develops it on the bit image memory 19. If the code is an image code, the code/bit converter 20 reads image information (bit image) from the word of the image memory 15 corresponding to the image code, and develops it on the bit image memory 19. That is, the code/bit conversion unit 20 treats the image memory 15 in the same way as the character font memory 12, and converts the image code into image information. Therefore, the code/bit converter 20 can have a simple configuration similar to that used when handling only characters. The bit image of the document developed in the bit image memory 19 is displayed by the CRT display unit 21.

Fortunately, image codes can be handled in the same way as character codes, so mixed editing of documents and images can be easily performed on the code memory 17 by word-by-word processing, which simplifies word processor programs. .

Although there is a central processing unit that executes the above-mentioned mixed editing, creation and editing of text on the character code memory 13, etc., in the processing of the progera l, it is not shown in FIG.

Effects of the Invention As described above, according to the present invention, since images can be processed word by word in the same way as characters, programs and hardware related to image processing can be simplified compared to the conventional ones, and various The effect of realizing a word processor with an image processing function at a low cost can be achieved.

Note that the present invention can be applied not only to word processors but also to information processing devices that handle images in general.
