In addition, the present invention provides a method of displaying image information on the screen of the portable mobile device, the step of generating the magnification window according to the call on the magnification function and the input screen coordinates and the movement of the input coordinates in the magnification window And moving the screen.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a portable mobile device having a designated location expanding function and a method for expanding the same. Referring to FIG. 1, a portable mobile device having a designated position expanding function includes a display unit 110, a memory 120, an external connection unit 130, a pointing input device 140, an enlargement function calling unit 150, and an enlarged designated position. The control part 100 including the module 105 is provided.

The display unit 110 is connected to the control unit 100 and displays an enlarged window in which the user enlarges around the coordinates input by the pointing input device 140 according to a signal applied from the control unit 100. do. In addition, as the coordinates on the screen input from the pointing input device 140 are moved, the screen in the magnification window is displayed while being moved. On the other hand, the display unit 110 may be divided into a display controller and a display device, and since the two are generally configured to have different operating speeds, the display interface 110 controls the difference in data representation format, electrical characteristics, and operation timing through an output interface. The device generally uses a liquid crystal display (LCD).

The memory 120 is connected to the control unit 100 and is a place for storing various information (eg, an address, an appointment, a memo and an e-mail message, etc. input by a PDA user).

The external connection unit 130 is connected to the control unit 100 and performs a function of exchanging information by connecting to a general telephone line, a cellular phone, or a PC.

The pointing input device 140 is a device connected to the controller 100 to be described later and inputs coordinates on a screen, and is a word encompassing input means for instructing an execution command intended by a user of the portable mobile device ( Various keys, fixed icons, character recognition panels, touch pens, etc.).

The magnification function call unit 150 is connected to the control unit 100 to be described later, and calls the magnification function to generate the magnification window according to the coordinates on the screen input from the pointing input device 140. To turn off zooming.

The controller 100 generates the enlargement window in a predetermined area by detecting on-screen coordinates input from the pointing input device 140 and whether the enlargement function call unit 150 calls the enlargement function, and the pointing input The screen is controlled to move the screen in the magnification window according to the movement of the coordinate input from the device 140. In addition, the controller 100 outputs a signal to the display unit 110 to visually display the screen coordinates first input by the pointing input device 140 on the screen in the enlarged window. This represents an incorrect selection correction function that prevents a user's possibility of wrong selection. For example, as shown in FIG. 3 to be described later, the portion M302 corresponding to the initially designated and input screen coordinate G302 may be displayed by a colored bold pointer P306. In addition, as shown in FIG. 4 to be described later, by detecting whether a coordinate value of an initially designated position is changed, an on-screen coordinate input of the screen in the enlarged window M300 (M400 of FIG. 4B) from the pointing input device 140. A signal is output to the display unit 110 to display while moving in the direction opposite to the movement direction of the. This provides the user with a magnifier to easily read large amounts of text on the enlarged screen within the magnification window.

That is, the control unit 100 which controls a predetermined designated position enlargement function receives a signal for a predetermined input state, and displays a portion M302 corresponding to the initially input screen coordinate G302 in the enlarged window (eg, 3, M300 of FIG. 3 and M400 of FIG. 4B, and a screen inputted from the pointing input device 140 to the screen in the enlarged window (eg, M300 of FIG. 3 and M400 of FIG. 4B). It controls to move in the direction opposite to the moving direction of the image coordinate. Meanwhile, the controller 100 controls the enlargement window to be generated when the same coordinate is continuously input at the same position for a predetermined time.

The designated position expansion module 105 is a module for selecting a range to expand around the coordinates of the position (for example, G302) designated by the pointing input device 140, and is included in the controller 100.

2 is a flowchart illustrating a method for expanding a designated position according to the present invention. First, a user starts a designated position enlarged function through the enlarged function call unit 150 (S200). In this case, the expansion function call unit 150 may be selectively used among hardware input devices such as a button or voice recognition, and may be alternatively used or simultaneously used in software.

The zoom function call signal is sent to the controller 100, and the controller 100 determines whether the same coordinates are continuously input from the pointing input device 140 at the same position for a predetermined time (S210). . In this case, if the coordinates of the same position are continuously input until a predetermined time interval elapses, the designated position enlargement module 105 in the controller 100 may enlarge the designated position enlargement window in a certain size and shape, and text. And which area around the GUI (Graphic User Interface) is to be enlarged, and at which position on the display the enlargement window is to be displayed. In this case, a predetermined time interval is preset in the controller 100 and may be set in advance by the user. In addition, the size and shape of the enlargement window are also preset in the designated position enlargement module 105 and may be preset by the user.

As a result of the operation of the designated position expansion module 105, the controller 100 controls the display unit 110 to generate an enlarged window displaying text or GUI screen according to the input screen coordinates (S220). In this case, as described above in the description of FIG. 1, the controller 100 detects the coordinates of the position on the screen first input by the pointing input device 140, and displays a portion corresponding to the coordinates in the enlarged window. It serves to transmit a signal to the display unit 110 to be displayed visually. Thus, there is an advantage that the size of the screen is small, thereby preventing the possibility of incorrect selection (correction correction function).

Meanwhile, while the magnification window is generated and the text or the GUI is displayed on the magnification window, the controller 100 detects whether a movement of the coordinates input by the pointing input device 140 occurs (S230). ). At this time, if it is determined that there is a movement of the coordinates, the controller 100 calculates a change value of the coordinates input by the pointing input device 140 and causes the display unit 110 to calculate the text or the GUI in the enlarged window. It is controlled to move according to the change value (S240). Therefore, according to the above function, the user can read and discriminate desired text or GUI while moving within the enlarged window on a small screen, and can accurately input.

After that, the control unit 100 detects whether there is a screen coordinate being input again (S250), and if there is no screen coordinate being input any more, the designated position expanding function is terminated (S260). If there are coordinates being input again, the process starts again from S210.

3A, 3B, and 3C illustrate a first embodiment using a designated position enlargement function, and the enlargement window M300 to visually recognize the on-screen coordinates G302 first input by the pointing input device 140. It has been shown that the misselection correcting function for displaying the portion M302 corresponding to the on-screen coordinates G302 first inputted within by the thick pointer P306 is used.

FIG. 3A illustrates a situation where a user attempts to press the end button G304 of the GUI portion G300 at the top of the screen on the small screen of the portable mobile device, but inadvertently presses the help button G302. At this time, when the designated position enlargement function is called and operated, as shown in FIG. 3B, when a predetermined time has elapsed while the user keeps pressing the help button G302 which is the first input coordinate on the touch screen, the enlargement window is displayed. M300 is generated in a predetermined area, and a thick pointer P306 appears in a portion M302 corresponding to the help button G302, which is an on-screen coordinate currently being input in the enlarged window M300, and is currently being input. The location of the coordinates can be easily recognized.

In the next step, FIG. 3C, since the user tried to press the end button G304 but the help button G302 was pressed, the coordinates on the screen are displayed by the pointing input device 140 while the on-screen coordinates are being input for a predetermined time. When moving to the right side, the screen in the enlarged window M300 moves to the left side, and a thick pointer P306 is positioned at the end button M304. At this time, the position of the thick pointer P306 is fixed, and only the picture in the enlarged window M300 is moved. In this way, when the user can enter the desired end button G304, the user has been continuously inputting the coordinates on the screen, and simply releases from the end button G304 that is being touched. The effect of pressing (G304) is generated.

4A and 4B illustrate a second embodiment using a designated position enlargement function, which moves a screen in the enlarged window M400 in a direction opposite to a moving direction of coordinates on the screen input from the pointing input device 140. Demonstrates using the Magnifier.

4A illustrates a step in which the user selects the first portion of the character string T400 to be viewed through the enlargement window on the screen. If the user continues to input the selected portion on the screen for a predetermined time or more, the front portion of the selected character string T400 is displayed in the enlarged window M400 of FIG. 4B.

As shown in FIG. 4B, when the pointing input device 140 that inputs coordinates while touching the first portion of the selected text T400 for a predetermined time or more moves to the right, the enlarged text shown in the enlarged window M400 is Will move to the left. In FIG. 4B, the arrow 402 facing right is a moving direction of coordinates on the screen input by the pointing input device 140, and the arrow 404 facing left is a moving direction of an enlarged character string.

Meanwhile, the magnification window M400 may be generated in a predetermined area set by the user on the screen, and at the moment when the position is overlapped with the character string part T400 corresponding to the coordinate on the screen input by the user. You can also set it to move down.

As a result, the user can enlarge and view a desired character string or GUI in an enlarged window displayed in a predetermined area on the screen, thereby reducing the possibility of misselection and moving while viewing the desired character string or GUI while being enlarged.

According to the present invention made as described above, the user can enlarge and read the desired character string by moving the screen in the enlarged window in the direction opposite to the moving direction of the coordinates on the screen input by the pointing input device, Since the part corresponding to the screen coordinates first input by the pointing input device can be visually recognized in the magnification window, it is possible to prevent erroneous selection.

Thus, the user can smoothly execute a command operated by a touch of the screen, enhance convenience, and increase the accuracy of selecting a designated position, and can implement a separate high resolution even in a small screen size.
