BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of editing a document and the like, and more particularly, to a method and apparatus for applying an image, a document, and the like displayed on a touch screen using a touch screen.

A touch screen refers to a device capable of receiving a signal by applying a fine current or pressure on a display. Therefore, it is very important to recognize the sensitivity of a touch screen when a signal is applied to the touch screen through a finger or the like. Recently, a capacitive touch screen having excellent response to an input signal has been developed, and various functions that can be performed through a touch screen in electronic devices are being developed. The touch screen is also used in most mobile devices in recent years in that it does not require a separate input device. As such, since the use of mobile devices has become commonplace, many of programs that have been performed through past computers are implemented through mobile devices. Therefore, it is important to design a user interface that allows a user to easily interact with various electronic devices It became a task.

Conventional user interfaces on touchscreen devices do not provide a simple and intuitive way to edit documents containing text, graphics, and the like. For example, in editing according to the related art, when setting format such as bold, italic, underline size of text in a document, etc., the text is first selected and changed through a format change menu. Since this conventional editing method takes longer than necessary and is inefficient, it has been required to develop a method and apparatus for document editing that reduces the perceived burden on the user and generates a more efficient man-machine interface.

1 is a block diagram of a document format modification algorithm processing module using a touch screen device according to an embodiment of the present invention.

Referring to FIG. 1, a document format modification algorithm processing module 1000 using a touch screen device according to an exemplary embodiment of the present invention may include a touch screen display unit 1100 and a processing unit 1200.

As shown in FIG. 1, the touch screen display unit 1100 may include a display panel unit 1110 for displaying an image and a touch screen panel unit 1120 for receiving a control signal. Accordingly, the touch screen display unit 1100 can receive not only a document or an image but also a signal for content control. The display panel unit 1110 and the touch screen panel unit 1120 can be implemented in one module according to the implementation method.

On the other hand, the processing unit 1200 may include a memory 1210 as needed. The memory may reside separately outside the processing unit 1200 according to various embodiments of the invention, and may not exist in yet another embodiment.

Hereinafter, the operation procedure in the document format change algorithm processing module for document format change will be described in detail.

FIG. 2 is a flowchart illustrating a document format changing algorithm in which a document format is changed according to an embodiment of the present invention.

First, when the user operates the touch screen to change the format, the form change information corresponding to the touch screen operation is received through the touch screen display unit 1100 (S100). In receiving form change information through the touch screen display unit 1100, various methods described below may be used, such as dragging a touch screen. In this specification, the document includes not only document programs such as Microsoft Office and Hancom Office but also all files that can be edited such as image files or video files. The available formats can include various formats such as a combination of one or more basic forms in combination with a default form provided in the text editor by default, or a definition form arbitrarily defined in advance by user's designation.

Upon receiving the format change information, the processing unit 1200 selects a format to be applied to the document based on the format change information received from the touch screen display unit 1100 (S110). If the changed formatting is the same as the format used by the user, the formatting is not changed. However, if the format change information is a combination of a user-specified format, or some format is different due to definition formatting, You can apply a new style only to parts.

When the format is changed according to the format change information, the user selects an area to which a new format is to be applied in the document, and receives application area information to which a new format is applied through the touch screen display unit 1100 (S120). In selecting a region to which a new format will be applied, a plurality of regions can be designated, and regions can be specified in various forms as will be described later.

The processing unit 1200 applies the selected document format to the designated area according to the received application area information (S130). As described above, the designated area may include various objects such as text, paragraph, picture, and table.

A step S200 of receiving form change information through the touch screen display unit 1100, a step S210 of selecting a form to be applied to the document in the processing unit 1200 according to the received form change information, (S220) of receiving the application area information to which the selected document format is applied through step 1100 and a step S230 of applying the document format selected in the processing unit 1200 according to the received application area information are the same as those of FIG. 2 (S100, S110, S120, S130).

After applying the document format (S230), it is checked whether there is an operation of canceling the format change from the user (S240). Examples of the operation for canceling the format change at this time include an operation of drawing an "X" character or a "/" character, an operation of sweeping down or sweeping the touch screen display unit with two fingers, And the like may be used. As an example of an operation opposite to the operation of applying the format, when tapping is performed at the beginning and end of the area, an operation of tapping in reverse order, an operation of dragging to the right, an operation of dragging to the left, And drawing a closed area in a counterclockwise direction when a closed area is drawn in a clockwise direction. In addition, a cancel button may be selectively used instead of the cancel operation as described above. This cancellation operation is not limited to the above embodiment, and various modifications may be made without departing from the scope of the present invention.
