Abstract

A document making method by a composition between image data and text data converts a hand written document or a keyboard input document to an image file, converts the addition, deletion, and correction concept to an image file, applies them to an original image file. Accordingly, the document making method can perform a correction, deletion, and addition about all documents. The document making method includes the steps of: converting a document made by a keyboard to an image file, and storing it; converting a hand written document to an image file by using a scanner or a camera; converting a text data input by a keyboard to an image data; composing a prior file and a new image file, compressing the composed file, and storing it to a record medium.

The present invention relates to a technique for creating a document by synthesizing image data and text data. In particular, the present invention relates to a method of synthesizing image and text data using a pattern and image processing technique and a data file compression method. The present invention relates to a method of creating a document by synthesizing image data and text data suitable for coexistence.

FIG. 1 is an explanatory diagram showing a document creation method that is generally used.

Data contains alphanumeric data and figures. In the existing system, all this data is treated as a single character code. That is, in the case of a picture, it is not possible to modify the data in the picture data by treating it as a kanji character, and if it is necessary to modify it, it is necessary to modify it using separate graphic data, and then call the data again and insert it into an existing document.

This means that textual data recorded as letters and numbers and image data that stores pictures do not coexist and are stored in a separate file, and the same units as existing handwritten documents and newly added data ( Cell).

In other words, whether you are creating a new document or a document that has been created by hand, all of them will be input through the keyboard using an editor such as a word processor and a dedicated program. In particular, existing hand-written documents are not stored in a file such as a disk, so a new form is inputted from the beginning. In this case, the document is stored in a disk file in ASCII code or Korean code.

In the case of English or numeric characters, ASCII codes, Korean characters or special characters, and 2-byte characters are converted into respective codes corresponding to the Korean combined and finalized characters. Especially in this case, even though the data of the picture document is image data, it is stored separately in a separate file or data. Moreover, it is impossible to directly add or modify the picture document.

As described above, in the conventional document creation method, the document can be edited and stored only in text data units. Therefore, if an existing document is stored as a handwritten document instead of a text file created using a computer, the existing document is stored. There is a problem that requires a lot of manpower and expense, because all must be input again to the same device, and because the picture and text can not be recorded in the same file, it must be managed in duplicate, it was impossible to modify in the same document.

Therefore, an object of the present invention is to add a new content to the document stored by hand through an input device such as a computer, to preserve the existing document as it is to create an image file and add the data to the text editor after the image The present invention provides a document creation method by synthesizing image data and text data which can be converted to a file to be synthesized.

The document creation method by synthesizing the image data and the text data of the present invention for achieving the above object comprises a first step of converting a newly created file through the keyboard into an image file and then compressing and storing the file in a recording medium; A second step of converting existing handwritten text into an image file using a scanner or a camera; A third step of converting text data input through the keyboard into image data to modify, delete, or add existing file contents; In order to correct an existing file converted into image data by the second process, all pixels within the existing file range are zeroed to omit or delete the existing file converted to image data and the converted new image file. And a fourth step of synthesizing and compressing the existing file and the converted new image file in order to add and end-combine or add them, and then storing them on a recording medium. When described in detail with reference to the accompanying 4 to 9 as follows.

For newly created documents, text data input through the keyboard is converted into image data, compressed, and stored in the recording medium.

Existing hand-written documents are converted into an image document using a scanner or read using a camera and then converted into an image document using an image processor as shown in FIG.

When deleting or modifying an existing file or adding new content to an existing file, the code of a character input through the keyboard changes to an image value in the same way as a scanner reads pixel data stored in video RAM. . That is, as shown in FIG. 6, values in the form of character units such as 8x8 or 16x16 are rearranged line by line from the top.

In this way, the converted file can be modified, deleted, or added with new contents. For example, if you add text or pictures to a specific location on an existing file, you can add existing image data and oasis from the desired location. As shown in FIG. 7, 0 is substituted for a part synthesized with image data of an existing image, and OA calculation is performed by inserting newly added data (eg, 1084,… 5050) at the position where the existing file ends. By doing so, the existing image data is not erased, but the data are superimposed on the data and the same effect as that recorded in the original document can be obtained.

However, since the amount of data in the image form is much larger than the amount of data in the text form, the image data is compressed to reduce the amount of files. In this case, the compression method used is run-lengh coding (Fig. 8). ), Huffman coding, arithmetic compression, LZ compression method, etc., and the document creation process is completed by storing the compressed file in a recording medium such as a hard disk, floppy disk, or optical file.

The process of deleting, adding, or modifying the existing file described above will be described in more detail with reference to FIG.

The user can determine the input position on the screen by using a keyboard or mouse and select or add a deletion mode while reading the compressed and stored image data and expanding it to the data before compression. You can select a mode or a correction mode.

When the erase mode is selected, the erase contents within the range determined on the screen are stored in the temporary memory, and all the contents within the range are deleted by AND combining all the pixels within the range with zero.

When the correction mode is selected, the video RAM data corresponding to the input content is temporarily stored in the buffer and the box window is output by the required sentence length from the position.

If conversion of Chinese characters is required by inputting characters from the first position of the box window, the characters are converted to Chinese characters, and the character data in the input box window is read in pixel units in the raster direction and stored in the buffer. The image is coded in pixels, nibbles, or bytes, and the input box window is removed.

Thereafter, the existing pixel data stored in the buffer and the pixel data input and stored from the first position of the box window are synthesized by an anion logic and re-memorized in a memory, compressed using a compression algorithm, and then stored in the memory.

When the additional mode is selected, the contents in the additional range selected on the screen are stored in the temporary memory as in the deletion mode, and all contents in the range are deleted by AND-combining all the pixels in the range with the correction mode. After the box window is output, the desired contents are added to the existing file, and afterwards, they are restored to the storage device through the compression process.

As described in detail above, the present invention converts a hand-written document or a document input through a keyboard into a mode image file and preserves it, and adds, deletes, and modifies the content to an image file, thereby converting the original image file. By applying it, any document can be modified, deleted or added.
