4 is a flowchart illustrating a method of controlling a mobile terminal according to a first embodiment of the present invention. Referring to FIG. 4, when an image file to be displayed is selected by entering a menu for displaying an image such as an album menu according to a user command, the controller 180 displays the image corresponding to the selected image file on a display unit (Step S200).

When an image is displayed on the display unit 151 and a touch signal is input through the area where the image is displayed (S205), the controller 180 displays an image edit menu for editing the image displayed on the display unit 151 (S215). The image editing menu can be displayed on the upper or lower border area, the left / right border area, or the like of the image displayed on the display unit 151. [ The control unit 180 continuously displays the image on the display unit 151 until the end of image display is selected (S210, S200).

If an edit function is selected by the touch input or the like in the image edit menu (S220), the control unit 180 checks whether an adjacent signal is detected from the proximity sensor 141 (S205). Examples of editing functions selected from the image editing menu include drawing functions such as line drawing and drawing of a figure, coloring functions such as paint barrel, spray (airbrush) and brush, eraser, eyedropper, magnifier, text input and formatting Etc., and an area selection function.

When a proximity signal is detected by the user's finger or the like on the display unit 151 after a certain editing function is selected in the image editing menu, the control unit 180 displays the selected editing function in accordance with the proximity indicated by the detected proximity signal. So that the detailed setting function is selected (S230). In addition, the control unit 180 controls the selected editing function to be performed according to the movement of the proximity position indicated by the proximity signal (S235).

Here, the detailed setting function means detailed setting items that can be selected from the selected editing function. For example, when line drawing is selected, the detail setting may be the width of the line or the shape of the line. Thus, the width of the line is selected according to the proximity indicated by the proximity signal, and a line may be drawn over the image as the proximity position moves.

When the brush function is selected by the editing function, the size of the brush is selected according to the proximity indicated by the proximity signal, and the brush of the selected size is moved according to the movement of the proximity position to be painted on the image. When the eraser function is selected by the editing function, the size of the eraser is adjusted according to the proximity indicated by the proximity signal, and the eraser with the selected size is moved according to the movement of the proximity position, thereby erasing the image. When the image selection function is selected by the editing function, the size of the image selection area is changed according to the proximity indicated by the proximity signal, and the image selection area is moved according to the movement of the proximity position. If so, the image area can be selected.

When the editing function is selected and the color to be used is selected (S235), the controller 180 causes the selected color to be used for image editing (S240). Otherwise, a default color or a previously set color is used for image editing (S245).

The process of performing the selected image editing function according to the proximity signal is repeatedly performed until the end of the selected editing function is selected (S250). If the end of the selected editing function is selected, the control unit 180 controls to return to the step S215 (S250, S215) to select another editing function or the like, and returns to the step S200 if the editing of the image is selected (S255, S200). The selected editing function is performed and the edited image can be stored in the memory 160 according to the user's selection.

In this way, when the image editing menu is displayed, a finger or the like can be brought close to the screen, a detailed setting function can be selected by the selected editing function, and a desired editing function can be performed by moving a finger or the like. Further, when the image edit menu is displayed and an area other than the area where the image edit menu is displayed is touched, the image edit menu disappears. The image editing menu disappears even if the proximity signal is not detected for a predetermined time.

In addition, the selection of the detailed setting function and the execution of the editing function may be performed simultaneously or sequentially. For example, when the user's finger moves on the image, the line may be drawn while the width of the line changes as the user's finger approaches the image. When the user's finger is close to the area with no image displayed, a menu for selecting the detail setting function is displayed to select the detail setting function first. If the user's finger is close to the image, Can be configured to be performed.

In order to perform a complex operation, a touch signal and a proximity signal may be appropriately mixed. For example, when the line drawing is selected, a line is drawn on the image according to the movement of the proximity position with the touched portion on the image as the starting point, and the line can be configured to be the end point when touched again.

In addition, an indicator icon indicating the proximity signal detection and proximity degree may be displayed on the display unit. In addition, the proximity signal may be detected or approximated by various methods such as a specific key or a blinking light signal of a lamp. In addition, an icon indicating the editing position may be displayed on the image.

 5 is a flowchart illustrating a method of controlling a mobile terminal according to a second embodiment of the present invention. In the present embodiment, a screen effect is given to the image displayed on the display unit in accordance with the proximity signal detected by the proximity sensor.

Referring to FIG. 5, when an adjacent signal is detected, an effect to be given to a screen is selected (S300). Examples of selected screen effects include noise, Render, Brush Strokes, Video, Sharpen, Sketch, Stylize, Art Effect, Artistic, Distort, Texture, Pixelate, Blur, and other effects. It is also possible to provide a separate menu for selecting a screen effect.

Next, when an image file to be displayed is selected in a menu for displaying an image according to a user command or the like, the controller 180 causes the display unit 151 configured with a touch screen to display an image corresponding to the selected image file (S305) .

The control unit 180 checks whether an adjacent signal is detected from the proximity sensor 141 in a state where an image is displayed on the display unit 151 (S310). As a result of the inspection, when a proximity signal is detected by the user's finger or the like in proximity to the display unit 151 or the proximity sensor 141 installed in the vicinity thereof, the control unit 180 displays the selected screen effect on the image (S315).

If the storage is selected for the image to which the screen effect is applied (S320), the control unit 180 causes the memory 160 to store the image having the screen effect (S325). At this time, a message indicating that the image having the screen effect is stored can be displayed (S330). The image to which the screen effect is given can be stored in the setting area of the memory 160 as a file name given by the control unit 180. [ Depending on the usage environment, a menu for selecting a storage location or file name can be displayed when an image is stored.

This process is repeatedly performed until the end of image display is selected (S335). In addition, although a case where one screen effect is given in the above process has been described, it is also possible to provide two or more screen effects according to the setting items.

On the other hand, when the proximity signal is detected, the screen effect given to the image will be described in more detail as follows. First, the noise effect is to add or control noise in the image. This includes adding noise to add color noise or black and white noise to the entire selection or image, despeckle to remove noise in the image, blurring colors that are not matched to surrounding colors as noise, (Dust & Scratches), which blur the number of pixels, and an intermediate value (Median) for calculating an average value by grouping pixels as many as the number of input pixels and uniformly applying the average value.

3D Transform (3D Transform) is to make a planar image including a hexahedron, a sphere, and a cylinder three-dimensional.
