[

Hereinafter, a method of displaying image data according to the present invention will be described with reference to FIG.

2 is a flowchart of a method of displaying image data according to an embodiment of the present invention. As shown, the image data is stored in the storage unit 160 of the mobile communication terminal 100 (S1). The user performs an image display command through the user input unit 130. [ Upon receipt of the image display command, the controller 180 compares the size (i.e., resolution) of the image data stored in the storage unit with the resolution of the display unit (S2). As a result of the comparison, if the image data is equal to or smaller than the resolution of the display unit 151, the image data is displayed on the display unit 151. If the image data is large, only the portion of the image corresponding to the size of the display (first display data) is displayed. Then, the sensing unit 141 senses the movement of the display unit 151. [ The movement of the display unit 151 includes vertical movement and tilt movement (S3, S4). The second display data is displayed by changing the display of the display unit 151 according to the sensing signal from the sensing unit 141 (S5). Then, the controller 180 checks whether the end of the second display data is a part of the end of the entire image data (S6). If one end of the second display data is a part of one end of the entire image data, it is notified to the user through the haptic module 154, the alarm unit 153, and the sound output module 152 (S7). According to the present invention having the above-described configuration, the user can not only view the original image data at the original size but also check the entire image through the motion detection signal.

Hereinafter, the principle of the image data display method according to the present invention will be described. FIG. 3 is a view for explaining the principle of image data display method according to the present invention. FIG. 4 is a view for explaining the principle of the first embodiment of the image data display method according to the present invention, Fig. 8 is a diagram for explaining the principle of the second embodiment of the image data display method according to the present invention.

3, reference numeral 200 denotes original image data, and reference numeral 100 denotes a mobile communication terminal. As shown, the size (resolution) of the original image data 200 is larger than the size (resolution) of the display unit 151. A part of the original image data 200 (also referred to as 'first display data') is displayed on the display 151, and only the resolution of the display unit 151 is displayed. The display unit 151 is disposed on the display unit 151 while the original image data 200 is displayed and the display unit 151 displays the original image data 200 200). Therefore, the original image data can be displayed on the display unit 151 without changing the image quality of the original image data. A method of displaying other original image data 200 portions not displayed on the display unit 151 on the display unit 151 in this state will be described with reference to Figs. 4 and 5. Fig.

4 is a view for explaining the principle of the first embodiment of the image data display method according to the present invention. As shown in FIG. 4, the original image data 200 is larger than the display unit 151 of the mobile communication terminal 100. 4A, when the display unit 151 of the mobile communication terminal 100 is tilted with respect to the original image data 200 by? ₁ , the tilt sensor 142 detects the? ₁ And informs the control unit 180 of this. Then, the control unit 180 controls the display unit 151 to display the second display data 210, which has been changed by the angle, in consideration of? ₁ . At this time, the controller 180 determines whether the end of the second display data 210 displayed on the display unit 151 is the same as a part of the end of the original image data 200. If it is judged to be the same, the user is informed through the sound output module 152, the alarm unit 153 and the haptic module 154 that the portion currently displayed on the display unit 151 is the end portion of the original image data 200 Can be informed. Alternatively, an animation effect (for example, an effect of changing color or marking a line at the end) may be given to the displayed end. On the other hand, when θ ₁ is changed to θ ₂ , the second display data 210 is displayed on the display unit 151 as shown in FIG. 4 (b). In this way, by tilting the display unit 151 with respect to the original data image 200, a desired portion of the entire original image data 200 can be confirmed.

4, the display data of the display unit 151 is changed according to the change of the angle with reference to the vertical axis of the display unit 151, but the present invention is not limited thereto. For example, even when the angle is changed with reference to the horizontal axis, the inclination of the display unit 151 may be sensed in the same manner, and the display of the original data may be changed according to the inclination.

5 is a diagram for explaining the principle of the second embodiment of the image data display method according to the present invention. More specifically, FIG. 5 is a diagram for explaining an image processing method using a vertical movement detecting unit. As shown in the figure, reference numeral 200 denotes original image data, 100 denotes a mobile communication terminal, and 300 denotes a user. When the display unit 151 of the mobile communication terminal 100 approaches the user, the vertical movement sensing unit (which may be composed of a gyro sensor and an acceleration sensor) senses this and the control unit 180 performs zoom- . That is, when the display unit 151 approaches the user, the alpha value becomes smaller, thereby allowing a wider range of the original image data 200 to be seen. On the other hand, when the display unit 151 moves away from the user 300, the value of alpha becomes larger, and thus the original image data 200 displayed on the display unit 151 becomes narrower. As described above, the user can perform the zoom-in and zoom-out processing on the original image data 200 by using the vertical movement detecting unit.

Hereinafter, the UI of the mobile communication terminal to which the image display method according to the present invention is applied will be described. FIG. 6 is an image diagram showing an example in which an image data display method according to the present invention is applied to a mobile communication terminal. Fig. 6 (a) shows a menu screen 300. Fig. The user can display the image file menu screen 400 on the display unit 151 through the user input unit 130 on the menu screen 300 (see (b) of FIG. 6). In the image file menu, a plurality of image files 410, 420, and 430 are displayed. Here, the user selects one image file through the user input unit 130. Then, as shown in FIG. 6 (c), a message screen 500 is displayed on the display unit 151. A message window 510 indicating "Would you like to see it in its original size?" Is displayed on the message screen 500. When the user selects "Yes" as an answer to this question message, the image processing method described in Figs. 1-5 is executed, and only a part of the original image data is displayed on the screen 600 (Fig. ) Is displayed. Thereafter, the motion detection sensor is activated to detect vertical movement or tilt (inclination) of the display unit 151, thereby changing the display of the display unit 151.
