Referring to FIG. 2, the controller 100 first checks whether a camera operation button is input in step 201. The camera operation button may be implemented as a shortcut button on the side of the terminal as described above. If the camera operation button is not input, the controller 100 performs a corresponding mode (eg, standby mode) in step 225. If the camera operation button is input, the control unit 100 proceeds to step 203 to drive the camera module.

After driving the camera module, the controller 100 displays a photographing standby screen on the display unit 103 for preview in step 205. The shooting standby screen is a screen for displaying an image captured by the camera 107 as a moving picture.

In the state where the photographing standby screen is displayed, the controller 100 checks whether an image editing key is selected by a user's manipulation. When the image editing key is selected, the controller 100 generates a point spot at a predetermined position (eg, the center) of the photographing standby screen in step 209. The point spot is for selecting an editing area and may be displayed in a point or figure (circle, rectangle) shape. That is, the point spot can be any display for designating an editing area.

In operation 211, the controller 100 sets the editing method for applying to the point spot by performing the editing method setting mode. Through the editing mode setting mode, the size of the region to be edited, the shape of the edit, and the editing effect can be set. Since the editing mode setting mode will be described in detail later with reference to FIG. 4, a detailed description thereof will be omitted.

After setting the editing methods, the controller 100 checks whether a direction button (up / down / left / right button) is input by a user's operation in step 213. If the direction button is not input, the controller 100 proceeds to step 217 and checks whether a shooting button for taking a picture is input. If the direction button is input, the controller 100 proceeds to step 215 and moves the point spot according to the input direction button, and then proceeds to step 217.

Referring to FIG. 3, first, in step 301, the controller 100 determines whether a key manipulation for selecting one of pre-stored images is detected. If the key operation is not detected, the controller 100 proceeds to step 321 to perform a corresponding mode (eg, standby mode). If a key operation for selecting a specific image is detected, the controller 100 proceeds to step 303 and displays the selected image on the screen.

In the state where the image is displayed, the controller 100 determines whether an image editing key is selected by a user's operation in step 305. When the image editing key is selected, the controller 100 generates a point spot at a predetermined position (eg, a center) of the displayed image in step 307. As described above, the point spot is for selecting an editing area and may be displayed in a point or figure (circle, square) shape.

In step 309, the control unit 100 sets an editing method for applying to the point spot by performing an editing method setting mode. Through the editing mode setting mode, the size of the region to be edited, the shape of the edit, and the editing effect can be set. Since the editing mode setting mode will be described in detail later with reference to FIG. 4, a detailed description thereof will be omitted.

After setting the editing methods, the controller 100 checks whether a direction button (up / down / left / right button) is input by a user's operation in step 311. If the direction button is not input, the controller 100 proceeds to step 315 and checks whether a confirmation button for requesting editing is input. If the direction button is input, the controller 100 proceeds to step 313 and moves the point spot according to the input direction button, and then proceeds to step 315.

In operation 315, the controller 100 checks whether a confirmation button for requesting the editing is input. If the confirmation button is not input, the controller 100 returns to step 311 to perform the following steps again. If the confirmation button is input, the controller 100 proceeds to step 317 and edits the displayed image by the editing methods set in step 309 based on the point spot. In operation 319, the controller 100 displays the edited image on the screen. Here, image processing such as editing and displaying an image is performed by the image processor 109 under the control of the controller 100.

FIG. 4 shows a detailed procedure of the editing method setting mode (step 211/309) described with reference to FIGS. 2 and 3. FIG. 4 shows some examples of various editing methods, and it will be apparent that various editing methods currently performed in image editing software for PC installation, in addition to the editing methods proposed herein, may be applied to the present invention.

Referring to FIG. 4, after generating a point spot on the screen, the controller 100 checks whether a menu button is input in step 401. When the menu button is input, the controller 100 pops up a menu window displaying a list of various editing methods in step 403. For example, the menu window may include items such as "1: size setting 2: shape setting 3: effect setting".

In the state where the menu window is displayed, the control unit 100 proceeds to step 405 and checks whether item 1 (size setting) is selected. In this case, when the first item is selected, the controller 100 displays a size list for designating the size of the point spot in step 407. For example, the size list may include items such as "1: 900 pixels 2: 1500 pixels 3: 2000 pixels". That is, the size of the region to be edited is set by designating the number of pixels to be edited around the point spot. In this way, you can specify the size by selecting one of the size lists, and you can specify the size of the editing area by directly entering the number of pixels.

In the state where the size list is displayed, the controller 100 proceeds to step 409 and checks which size is selected from the size list. In this case, when a specific size is selected, the controller 100 proceeds to step 411 and sets the selected size to the size of the edit area and then proceeds to step 413.

On the other hand, if the item 1 is not selected in step 405, the controller 100 checks whether item 2 (shape setting) is selected in step 415. In this case, when the second item is selected, the controller 100 displays a shape list for designating a shape of a point spot (or an editing area). For example, the shape list may include items such as "1: circle 2: ellipse 3: star 4: heart". In the state where the shape list is displayed, the control unit 100 proceeds to step 419 and checks which shape is selected from the shape list. In this case, when a specific shape is selected, the control unit 100 proceeds to step 421 and sets the selected shape to the shape of the editing area and then proceeds to step 413.

On the other hand, if the item 2 is not selected in step 415, the controller 100 proceeds to step 413 and checks whether item 3 (effect setting) is selected. At this time, if the item 3 is not selected, the control unit 100 returns to step 405 again and performs the following steps again. On the other hand, if the item 3 is selected, the controller 100 proceeds to step 425 and displays an effect list for giving various effects to the area designated as the point spot. For example, the effect list includes "1: black and white 2: print effect 3: rotation 4: faded photo effect 5: mosaic 6: light 7: point light 8: dark 9: point dark 10: text signature 11: insert background" It can contain the same items. As can be seen from the above list, various editing is possible based on the point spot. For example, you can mosaic a spot, insert a specific background (e.g. sea, sky, etc.) outside of the spot, lighten it only to highlight it, or darken it, or spot it. You can enter any text you want in the field.

In the state where the effect list is displayed, the control unit 100 proceeds to step 427 and checks which effect is selected from the effect list. In this case, when a specific effect is selected, the controller 100 proceeds to step 429, sets the selected effect as an effect to be applied to the point spot, and proceeds to step 413.

On the other hand, the control unit 100 checks whether the confirmation button is input in step 413. At this time, if the confirmation button is not input, the control unit 100 returns to step 401 and performs the following steps again. On the other hand, when the confirmation button is input, the controller 100 ends the editing method setting mode according to the present invention.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, the present invention allows a user to select a desired portion by moving a point spot, and the size and effect can be set freely, so that various images can be directly displayed on a terminal without a personal computer (PC) operation. There is an advantage to editing in a way.
