Abstract

PURPOSE:To enable reduction of memory capacity necessary for recording document by recording document classifying it into character code information vector information of graphic and picture information. CONSTITUTION:When whole document is changed into dot pattern and inputted to a picture memory 52, monitoring is made by a display 53. After confirmation of desired document making, information necessary for document reproduction is recorded in an optical disk device 54 through a keyboard 56. In this case, code stored in a code memory 55 is recorded for sentence and graphic, and dot pattern of the part of a picture memory 52 is recorded for picture together with address information that indicates respective display position. Accordingly, when the device 54 is read out, a controlling device 51 generates character pattern from character code, and generates dot pattern that indicates a graphic from vector information, and they are stored in designated address position. By adopting such a recording method, memory capacity can be decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document file device that converts the information of a document containing a mixture of characters, figures, and images into a digital signal. In the figure showing an example, (1) shows the entire document comprehensively, (2) is a text, (3) is a figure, (41 is an image, (21) is a character, and (31) is a line segment. Symbols and simple figures whose dot patterns have a predetermined code are considered to be included in the character (2J).Since there is no regularity in the image (4), it can be interpreted as an electrical signal. When converting to a video signal, for example, a television camera scans it to obtain a video signal representing the image.For example, if the television camera has 8 scanning lines in 1 ntn, the image (4
1 of 1 1 mm The square part of the corner is 8 x horizontally and vertically
It is decomposed into 8=64 pixels and the information of each pixel is represented. The simplest way to express the information of each pixel is 1
The information of a pixel is represented by a 1-bit I= symbol, and whether the logic of that bit is "1" or "0" is expressed as "
It is fine if it corresponds to "white" or "black". Since the generation and storage of image information (1) above is well known, a general explanation thereof will be omitted, or conventional document file devices may store the entire document (1) as one image and file. , for example, scan this with a television camera, convert the output video signal into a binary signal, and convert it to 211G.
A document file is created by recording a signal at a predetermined address in synchronization with the above-mentioned scanning.Therefore, in conventional devices, the number of bits that must be stored in the document file for one document is large. was there. Figure 2 is a diagram showing the character frame (22) in which one character (21) is written, but the character frame (22) is
If it is a square of mm, then the square of l mtn is 64
In the example above, one character (2
To memorize 1) 5 x 5 x 64 = 1.60
This would require a 0-bit storage element. On the other hand, even when character codes represent a large number of kanji, each character is represented by a code of about 16 bits, and when stored as character codes, the amount of data is much smaller than when stored as character patterns as image information. Figure 3 shows the line segment (31), (32) is its starting point, (33) is its end point, and C-34) is the line segment (3). )
The actual dimensions of a frame with a diagonal of k 20 mm x
15 tnm, to store line segment (31) as a dot pattern, 20 x 15 x 64 = 19
, a 200-bit memory element is required. However, the information on the Ja spasm (32) and the end point (33) are each given as approximately 32 bits of information, and by calculating from these information, the line segment ( 31) It would be easy to generate the dot pattern, so it would be better to store the vector information in a figure with some regularity and then generate the dot pattern from there. Storage capacity can be significantly reduced.

This invention was made in view of the above-mentioned facts, and in the entire document (1), sentences (21) are stored as character codes, figures (3; are stored as vector information, and images (4) are stored as vector information. Create a document file by storing the overlap as dot information, convert the character code read from this document file into a character pattern, generate a graphic dot pattern from the vector information, and create a dot pattern of the image read from the document file. In addition, the entire dot pattern is edited and displayed on a display device via an image memory.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 4 is a block diagram showing a simple embodiment of this invention. ￥
