Description

How to magnify an ebook image {Method of magnifying image of electronic book}

The present invention relates to a method for enlarging an e-book image, and more particularly, to a method for easily enlarging an e-book image without a preprocessing image.

The speed of informatization using computers and networks is developing rapidly around the world. In particular, as the integration of the controller and memory has become very high, the size of computers is becoming smaller and smaller, and the thickness of the display devices such as LCD and OLED is becoming smaller, and mobile terminals are also remarkably developing.

As a result, in recent years, e-books, which can easily carry large-capacity books through small-sized mobile terminals, have been rapidly spreading instead of paper having high production cost and low portability to capacity. .

However, in order to use an e-book through a display having a small size of 3 inches to 7 inches, a problem of securing readability has emerged. Accordingly, as a software technology for easily expanding an image to a predetermined magnification is developed, an e-book can be easily read through a small display.

However, conventionally, in order to enlarge an image of an e-book, a pre-processed image, that is, image data enlarged at various magnifications is stored in advance, and then a region to be enlarged is selected and the stored enlarged image data is called. .

This method requires preprocessing images for all images of the ebook, and the preprocessing images grow in proportion to the number of pages of the ebook. Therefore, an excessively large capacity of the e-book has caused a decrease in image magnification processing speed and poor readability.

An object of the present invention for solving the above problems is to provide a method for enlarging an e-book image that does not require a pre-processed image.

According to an aspect of the present invention, there is provided a method of enlarging an e-book image according to an aspect of the present invention. Specifying a region, capturing the designated region in a storage means including a buffer memory, and enlarging the region stored by the capture at a predetermined magnification and displaying it on a display.

According to an embodiment of the present invention, the area may be one of areas pre-divided on the image of the specific page.

According to another embodiment of the present invention, the region can be arbitrarily designated using a mouse. The method for designating the region using the mouse point may include recognizing initial coordinates of the mouse point by a mouse click execution signal, and determining final coordinates of the mouse point by the end signal of the mouse click execution. Recognizing may include the step of designating the region calculated by the preset method by the initial position and the final position.

According to the present invention, it is possible to perform image enlargement at a high speed so that sufficient readability can be secured by simple capturing without requiring a large amount of preprocessed images for image enlargement of an e-book. E-book capacity can be significantly reduced. Therefore, the readability of the e-book is greatly increased.

Hereinafter, a method for enlarging an e-book image according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments, and is generally used in the art. Those skilled in the art will be able to implement the present invention in various other forms without departing from the spirit of the present invention.

1 is a flowchart illustrating a method of enlarging an e-book image according to an embodiment of the present invention.

Referring to FIG. 1, in the method of enlarging an e-book image according to the present embodiment, an e-book file is first loaded into an e-book viewer device (S100). The e-book viewer device may use a variety of computing devices such as a general personal computer, PDA, MP3, e-book reader (e-book reader).

The e-book file includes a PDF file, a text file, a word processor file, a PDF file, and the like, depending on the operating system of the e-book viewer device and the type of viewer program. Any modification is possible.

Although not shown, after the user loads the e-book file, the user uses the page flipping means such as a direction key button, a jog wheel, a mouse, and a touch pad input provided in the e-book viewer device. You will read the e-book displayed on.

On the other hand, the magnification of the image is set according to the user's operation (S110). For example, the enlargement ratio may be set using the icon 102 provided in the e-book viewer device or the viewer program. The enlargement ratio can be changed at any time according to the user's preference according to the size of the display provided in the e-book viewer device.

3 and 4 are computer screens for explaining the e-book image enlargement processing method shown in FIG.

1 and 3, after the e-book file is loaded, the image is intended to be enlarged on an image 110 representing a specific page of the e-book loaded in the e-book viewer device using a predetermined input means M1. Specify an area (S120). For example, the image 110 of the particular page is divided into divided regions 112 of the screen. Accordingly, one of the pre-divided regions can be easily designated by, for example, a mouse click using the input means M1.

Next, when the designated area 112 is selected, the area 112, that is, the image 112 corresponding to the area, is automatically stored in a predetermined storage means (not shown) (S130). For example, the storage means is preferably a buffer memory. Alternatively, the image files of the individual areas may be stored on a nonvolatile memory such as a ROM, in which case the stored image file will be called by the area selection of the input means M1.

1 and 4, the area 112 stored by the capture is enlarged at a predetermined magnification and displayed on the display (S140). For example, the designated area 112 is displayed on the corresponding page image 110 in an image 120 enlarged by a specified ratio, for example, 4 times. In this case, it is preferable to make the image 110 of the corresponding page transparent by 20% to 60% so that the enlarged area 120 is relatively highlighted with respect to the image 110 of the corresponding page.

As described above, by selecting the area 120 to be enlarged among the pre-divided sections and immediately expanding it at a specified ratio, it is possible to easily enlarge the e-book without enlarged pre-processed images as in the prior art to improve readability. have.

Referring to FIG. 2, the method of enlarging an e-book image according to the present embodiment includes loading an e-book file (S100), setting an enlargement ratio (S110), capturing an enlarged region (S130), and capturing. The step S140 of displaying the displayed screen at the set magnification is similar to the method of enlarging the e-book image according to the embodiment of the present invention described above. Detailed description thereof will be omitted.

The present embodiment is characterized in that an image representing a particular page of an e-book is not divided into sections, and the user can arbitrarily designate an area to be enlarged using a mouse.

5 and 6 are examples of computer screens for explaining the e-book image enlargement processing method shown in FIG.

2 and 6, first, a means for inputting a position corresponding to a predetermined coordinate value, such as a mouse M2 or a mouse, is used. For example, the initial coordinates of the mouse point are input by the click execution signal of the mouse M2 (S122). The user expands the area by dragging mouse M2 in the clicked state.

Next, the final coordinates of the mouse point are input by the end signal of the mouse M2 click execution (S124). That is, when using a mouse, the mouse position at the time when the dragging ends is a coordinate reference for transmitting the end signal.

Subsequently, the enlarged area 220 is calculated and automatically assigned based on the initial position and final position values (S126). Alternatively, the magnified area 120 may be designated by forming a closed loop by inputting a click signal to a plurality of points using the mouse M2.

Finally, referring to FIG. 6, the enlarged region 220 is enlarged and displayed according to a preset magnification, and at the same time, other portions of the corresponding page 110 in which the region 220 exists are transparent and additional signals, eg For example, the enlarged region 220 may be terminated by clicking a predetermined key, and the image of the original page may be returned to its original state.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art will variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. I can understand that you can.
