Description

Electronic book for displaying emulation data at screen inputting from outside}

The present invention relates to an e-book, and more particularly, to a method for outputting to an e-book using a printer output image produced by an application program in an office device such as a computer.

In general, office devices such as computers and printers have mostly functions for performing tasks through a certain space, such as creating documents and outputting documents through printing paper. However, as the functions of these office equipments gradually increase, office equipments of recent years become more portable, and office equipments that sufficiently perform the existing functions with easier user operations have emerged. Portable e-books have emerged for this need.

An e-book is a new type of book called the nickname of an electronic book (eBook). It is a book-shaped electronic device that can be carried like a personal digital assistant (PDA). Typically, e-books are about the size of a paperback displayed in a bookstore and weigh about a pound heavier than paper books. In addition, the e-book has a display such as an LCD window so that the user can view the document, the bookshelf is turned over when a predetermined button is pressed. The standard for e-books was published by the Association of Open eBook Forums (OEBF), a common specification for e-book systems, Standard Version 1.0.

The conventional e-book converts input document data converted into a format suitable for the e-book into raw data standardized for each page through a data processing module (not shown) and displayed on the screen. Such an e-book displays document data pre-converted into a format that can be converted into raw data in the e-book. Therefore, a special module capable of converting an e-book into a low data format can be mounted on a document editing apparatus such as a computer connected to the e-book. Accordingly, the document editing apparatus requires not only the corresponding document editing module for document editing but also a corresponding converting module capable of converting the document edited by the document editing module into a format recognizable by an electronic book. This operation is cumbersome when the user uses, and also inconvenient that the user must learn the ability to use the conversion module in order to use the e-book.

In order to solve this inconvenience, the document editing device may be equipped with a specific e-book document editing module recognizable by the e-book. In addition, the user needs to utilize the specific e-book document editing module mounted in the document editing apparatus. Therefore, the inconvenience of having to learn the ability to use the new e-book document editing module. In addition, since different e-book editing modules are provided for each e-book, there is a problem that the compatibility of each e-book is inferior. As such, since the e-book specific conversion module and the document editing module need to be installed in the document editing device to be connected to the e-book, the user is burdened to separately purchase the corresponding module necessary for the use of the e-book. .

On the other hand, in order to receive and display document data using such a conventional e-book, it is cumbersome to mount a module corresponding to the e-book on each document editing device to be connected to the e-book. In addition, the conventional e-book has a problem in that when the document data received by the format conversion is converted into the raw data and displayed on the screen, it is displayed differently from the form of the document data displayed on the screen of the document editing apparatus. Accordingly, the user can check the document displayed on the screen of the e-book to visually recognize the document.

An object of the present invention for solving the above problems is a form of a document in which the corresponding document data edited in the document editing apparatus without a separate e-book specific conversion module and document editing module in the document editing apparatus is displayed on the screen of the document editing apparatus. To provide an electronic book that can be displayed on the screen of the document of the form, such as.

Here, parsing refers to checking whether a given sentence can be legally used as a single sentence according to the grammar structure defined in the e-book. A layout is a well-balanced layout of text, headings, figures, and tables in the emulation data in the appropriate places on the page. In addition, rendering means precise detailing, and in order to display emulation data on the screen, it is a method of giving various three-dimensional impressions to the emulation data. The process of adding realism to the document displayed in the.

Thus, the same number of pages as the document displayed on the screen 12 is displayed on the LCD window 28, so that the same characters can be arranged in the same line and cell on the screen 12 and the LCD window 28. FIG.

3 is a flowchart illustrating a data receiving processing method using an e-book according to the present invention. Referring to the drawings, first, the microcomputer 22 determines whether emulation data input to the interface unit 24 is present (S40). If it is determined in step S40 that the emulation data is input, the microcomputer 22 controls the row data converter 44a of the format converter 44 to convert the emulation data into row data (S42). Here, the display setting unit 44b sets the display including the resolution so as to display the raw data, into which the emulation data is converted, on the LCD window 28 (S44). On the other hand, the display unit 26 displays the display-set raw data on the LCD window 28 according to the set display value.

Thus, the display format of the raw data displayed on the LCD window 28 is the same as the display format of the document data displayed on the screen 12 of the computer 10. That is, the number of pages for character data displayed on the LCD window 28 and the number of pages for characters displayed on the screen 12 are the same. In addition, when the same page is displayed for the same character data on the LCD window 28 and the screen 12, the corresponding characters displayed on the screen 12 and the LCD window 28 are arranged in the same line and cell. For example, if the word 'Hangul' recorded once on the page is displayed on the screen 12 in the 23rd to 27th columns of the 20th line of the 7th page, the word 'Hangul' converted to the low data is displayed on the LCD window. In (28), the seventh row is placed in the twenty-third column from the twenty-third line of the seventh page.

Thus, they are placed on the same page, line, and cell for the same corresponding character.

At this time, the microcomputer 22 determines whether the storage command signal for the low data displayed on the LCD window 28 is input through the user interface 32 by the user (S48). If the storage command signal for the low data is broken in step S48, the microcomputer 22 stores the raw data displayed on the LCD window 28 in the data storage unit 46 of the auxiliary memory device 40 (S50). .

Therefore, it is displayed on the LCD window 28 in the same format as the document data displayed on the screen 12, thereby reducing the time required for the user to check the document.
