Description of FIG. 4 - Proximity Touch

The proximity sensor 141 described with reference to Fig. 1 will be described in more detail with reference to Fig.

4 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

As shown in FIG. 4, when a pointer such as a user's finger, a pen, or the like approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen senses the proximity sensor and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to the distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

In FIG. 4, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is positioned on the touch screen by a distance d ₁ or more and less than distance d _2, the pointer is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is positioned apart from the touch screen by a distance d ₃ or more, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity depth and proximity position of the pointer, and perform various operation control according to the various input signals.

5 is a conceptual diagram for explaining a control method for a touch operation in a form in which a pair of display units 155 and 156 are overlapped.

The terminal shown in this figure is a folder type terminal connected to a main body so that a folder portion is foldable. The first display unit 155 mounted on the folder unit may be of a light transmitting type or a transparent type such as TOLED or the second display unit 156 mounted on the main body may be a form that does not transmit light like an LCD. The first and second display units 155 and 156 may be configured as a touch screen capable of touch input, respectively.

For example, when a touch (contact touch or proximity-touch) to the first display unit (for example, TOLED) 155 is detected, the control unit 180 displays the type of touch And at least one image of the image list displayed on the TOLED 155 according to the touch time may be selected or run.

Hereinafter, with respect to the manner in which the information displayed on the second display unit (e.g., LCD) 156 is controlled upon touching the TOLED 155 exposed to the outside in an overlapped form, Long touch and drag (drag).

In the overlapped state (the mobile terminal is in a closed state), the TOLED 155 is arranged to overlap the lower side of the LCD 156. In this state, if a touch such as a long touch (for example, a touch that lasts for 2 seconds to 3 seconds) is detected in a manner different from the touch for controlling the image displayed on the TOLED 155 in advance, ) Causes at least one image of the image list displayed on the LCD 156 to be selected in accordance with the sensed touch input. The result according to the execution of the selected image is displayed on the TOLED 155.

The long touch may also be used to selectively move a desired one of the entities displayed on the LCD 156 to the TOLED 155 (without performing any action thereto). That is, when a user selects one area of the TOLED 155 corresponding to a specific entity of the LCD 156 In the case of a long touch, the control unit 180 moves the corresponding object to the TOLED 155 to be displayed. The entity displayed on the TOLED 155 may also be displayed on the LCD 156 by a predetermined touch input to the TOLED 155, for example, flicking, swirling, and the like. In this figure, the menu No. 2 displayed on the LCD 156 is displayed on the TOLED 155.

If another input, for example, a drag, is detected in addition to the long touch, the control unit 180 is a function related to the image selected by the long touch. For example, a preview screen for the image is displayed on the TOLED 155, As shown in FIG. In this drawing, a case where a preview (male photograph) is performed on the menu No. 2 (image file) is illustrated.

The control unit 180 displays a selection cursor (or a selection bar) of the LCD 156 in the state that the preview screen is being output, while dragging toward another image is further performed on the TOLED 155 while maintaining the long touch And displays the image selected by the selection cursor on a preview screen (female photograph). Thereafter, when the touch (long touch and drag) ends, the controller 180 displays the first image selected by the long touch.

When the slide (the operation of the proximity touch corresponding to the drag) is detected together with the long proximity touch (the proximity touch continuing for at least 2 seconds to 3 seconds) to the TOLED 155 .

When a touch operation other than those described above is detected, the controller 180 can operate in the same manner as a general touch control method.

The control method for the touch operation in the overlapped form can be applied to a terminal having a single display. In addition, the present invention can be applied to a terminal different from a folder type having a dual display.

Description of Figure 6 -

FIGS. 6A and 6B are views referred to the description of the proximity touch recognition area where the proximity signal is detected and the haptic area where the tactile effect occurs.

6A shows an object such as an icon or a menu item in a circular form for convenience of explanation. The area of the object displayed on the display unit 151 can be divided into a first area A in the center and a second area B surrounding the center area as shown in FIG. 6A. The first region A and the second region B can be configured to generate tactile effects having different intensities or patterns. For example, when the second region B is touched, a first vibration is output, and when the first region A is touched, a second vibration larger than the first vibration is output.

In the case where the proximity touch recognition area and the haptic area are simultaneously set in the area where the object is displayed, the haptic area where the tactile effect is generated and the proximity touch area where the proximity signal is detected Can be set differently. That is, the haptic area may be set narrower than the proximity touch recognition area, or the haptic area may be set wider than the proximity touch recognition area. For example, in (a) of FIG. 6A, the area including the first area A and the second area B may be a proximity touch recognition area, and the first area A may be set as a haptic area.

(N > 4) as shown in Fig. 6 (a), as shown in Fig. 6 (b) It is also possible to divide into two areas. Each divided region can be configured to generate a tactile effect with different intensities or patterns. Even when the area in which one object is displayed is divided into three or more areas, the haptic area and the proximity touch recognition area can be set differently according to the use environment.

The size of the proximity touch recognition area may be changed depending on the proximity depth to the display unit 151. [ That is, as shown in (a) of FIG. 6, the corresponding proximity touch recognition area may be gradually reduced to 'C', 'B', and 'A' according to the proximity depth to the display unit 151, Or the contiguous touch recognition area corresponding to the proximity depth to the display unit 151 may be gradually increased. In this case as well, the haptic area can be set to a constant size regardless of the proximity depth to the display unit 151, such as the 'H' area shown in FIG. 6B (b).

 In the case of dividing the area in which the object is displayed for the setting of the haptic area or the proximity touch recognition area, in addition to the concentric segmentation as shown in Fig. 6A, segmentation in the horizontal direction or vertical direction, radial segmentation, And various methods such as partitioning can be used.

Referring to FIG. 8, the projector 801 of the mobile terminal projects blue light to the projection area 803, and the camera 802 captures an image of the projection area and stores the image in the memory.

At this time, the light projection angle of the projector 801 of the mobile terminal and the photographing angle of the camera 802 are in the same direction, so that the image of the projection area in which the light projected by the projector 801 is projected can be easily photographed by the camera . ≪ / RTI >

In step S703, the mobile terminal determines whether the user selects a background video.

9, the video selection interface

9 is a diagram illustrating an embodiment in which a user selects a background moving picture in a mobile terminal according to the present invention.

Referring to FIG. 9, the mobile terminal outputs a predetermined user interface 901 so that the user can select whether to synthesize the background video, and when the user selects to synthesize the background video, And outputs a user interface 902 having a user interface.

The user can select one of a plurality of background moving images (e.g., desert, forest, space, city background, etc.) and synthesize the selected image with the photographed image. For example, the user selects a desert background and selects it to be composited on the photographed image.

The background video may be a video to be synthesized with a video shot by a user, and the mobile terminal may store various background videos in a memory, and then provide a background video selected by the user to the shot video.

In this case, the moving picture is a moving picture stored in the mobile terminal, and may be a moving picture selected and input by the user.

In addition, the moving image may be downloaded from a predetermined server in the wireless communication unit 110, or may be a moving image photographed by a user in advance in the mobile terminal.

If it is determined in step S703 that the user has selected the background moving image, in step S704, the mobile terminal reads a photographing part excluding the background part photographed in the specific color among the images, And corrects the color of the photographed portion excluding.

If blue light is projected from the projector, the mobile terminal reads only the photographed portion after excluding the background portion photographed in blue in the image, and corrects the blue color in the photographed portion. This is to restore the photographed image by removing the influence of the blue color of the projector on the actual image.

Next, in step S705, the mobile terminal replaces the background part photographed in the specific color among the photographed images with a background video selected by the user, thereby generating a composite video.

Next, in step S706, the mobile terminal outputs the generated composite moving image to the display screen of the mobile terminal.

For example, if the user selects 'desert background', the mobile terminal may synthesize the captured portion of the images captured by the camera with the 'desert background' video to generate a composite video and output it.

Accordingly, the present invention can be applied to various applications of a background of a video image photographed by a user by projecting light of a specific color from the projector of the mobile terminal, photographing the projection area by the camera, and replacing the background part of the projection area with the background video It is possible to make it possible to make it possible.

For example, if the user wishes to set the background of the video shot by the mobile terminal to 'desert', the 'desert' background part is synthesized with the capturing part and output, So that it can be made easily.
