A power supply unit 190 for supplying power to the portable terminal 100 is mounted on the terminal body. The power supply unit 190 may be built in the terminal body or may be detachable from the outside of the terminal body.

The rear case 102 may further include a touch pad 135 for sensing a touch. The touch pad 135 may also be of a light transmission type like the display unit 151. [ In this case, if the display unit 151 is configured to output time information on both sides, the time information can be recognized through the touch pad 135 as well. The information output on both sides may be all controlled by the touch pad 135. [ Alternatively, a display may be additionally mounted on the touch pad 135, and a touch screen may be disposed on the rear case 102 as well.

The touch pad 135 operates in correlation with the display portion 151 of the front case 101. The touch pad 135 may be disposed parallel to the rear of the display unit 151. The touch pad 135 may have a size equal to or smaller than that of the display unit 151.

Hereinafter, a related operation of the display unit 151 and the touch pad 135 will be described with reference to FIGS. 3A and 3B.

3A and 3B are front views of a portable terminal for explaining an operation state of the portable terminal according to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

At least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement for inputting such information, thereby being implemented as a keypad. Such a keypad may be called a so-called " soft key ".

FIG. 3A shows a touch input to a soft key through a front surface of a terminal body.

The display unit 151 may operate as an entire area or may be divided into a plurality of areas and operated. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. The output window 151a and the input window 151b are areas allocated for outputting or inputting information, respectively. In the input window 151b, a soft key 151c in which a number for inputting a telephone number or the like is displayed is output. When the soft key 151c is touched, a number corresponding to the touched soft key is displayed on the output window 151a. When the first operation unit 131 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

FIG. 3B shows the input of a touch applied to the soft key through the rear surface of the terminal body. FIG. 3A shows a case where the terminal body is vertically arranged, and FIG. 3B shows a case where the terminal body is arranged horizontally. The display unit 151 may be configured to convert the output screen according to the arrangement direction of the terminal body.

3B shows that the text input mode is activated in the portable terminal. The display unit 151 displays an output window 151a 'and an input window 151b'. In the input window 151b ', a plurality of soft keys 151c' displayed with at least one of letters, symbols, and numbers may be arranged. The soft keys 151c 'may be arranged in the form of a QWERTY key.

When the soft keys 151c 'are touched through the touch pad 135 (see FIG. 2B), characters, numbers, symbols corresponding to the touched soft keys are displayed on the output window 151a'. As described above, the touch input through the touch pad 135 is advantageous in that the soft key 151c 'can not be blocked by the finger when the touch is input, compared with the touch input through the display unit 151. [ In the case where the display unit 151 and the touch pad 135 are formed to be transparent, the fingers located on the rear side of the terminal body can be visually confirmed, thereby enabling a more accurate touch input.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This will be useful for editing the image displayed on the display unit 151. [

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be activation or deactivation of the display unit 151 or the touch pad 135, for example.

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 (a contact touch or a proximity-touch) to the first display unit or the TOLED 155 is detected, the control unit 180 determines whether the touch At least one of the images displayed in the TOLED 155 may be selected or run.

Hereinafter, with respect to the manner in which the information displayed on the other display unit or the LCD 156 is controlled when touching the TOLED 155 exposed to the outside in an overlapped form, a touch, a long touch, a long touch and drag ), And so on.

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 according to 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.

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.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The mobile terminal of the present embodiment uses a method of combining a drawing pattern created in accordance with a user's pointing operation with moving image data to be converted into moving image data to be transmitted through a video call, in a form of moving image data. In the case of this embodiment, there is an advantage that the drawing pattern according to the present invention can be output without having a separate additional module, as long as the other terminal supports the video call.

FIG. 7 illustrates a mobile terminal for video communication capable of transmitting a drawing pattern according to an embodiment of the present invention.

The illustrated mobile terminal includes a touch screen 159 as a pointing receiving device for receiving a user's pointing operation; A pattern generating unit 184 for generating a drawing pattern from a pointing operation input from the touch screen 159; A camera module (121) for generating pixel dim values corresponding to intensity and / or amount of light incident on each pixel; A moving image combining unit (185) for generating moving image data from the pixel light sensitivities, and attaching the drawing pattern generated by the pattern generating unit to the moving image; And a mobile communication module 112 for transmitting the moving image generated by the moving image combining unit 185 through a wireless communication channel.

According to the implementation, the pattern generator 184 and the moving image combiner 185 may be internal HW and / or SW modules of the controller 180 of FIG.

Here, the moving image combining unit 185 may include a frame buffer 187 for collecting the pixel gray values and generating frame data corresponding to a still image in a screen unit; An image combining unit (186) for combining the frame data and the drawing pattern; And a moving image converting unit 188 for converting the combined image data in the image combining unit 186 into moving image data.

Although the illustrated mobile terminal has the touch screen 159 as a pointing receiving device, it may be replaced with various user operating devices such as a trackball or a navigation key. The pointing reception device is specifically for performing an operation of obtaining two-dimensional coordinate values for a point pointed by the user in the screen of the mobile terminal.

The pattern generator 184 receives information on the pointing operation from the touch screen, and performs a function of estimating a pattern intended by the user.

For example, if the touch screen 159 outputs coordinate values for a point where pointing is performed in a relatively short period for human detection, the pattern generating unit 184 generates coordinates You can collect the values to generate the pattern. At this time, the pattern generation unit 184 may store a coordinate value or the like collected as the pattern in a memory or the like.

The pattern being generated by the pattern generator 184 may be a display of a mobile terminal that is generating a pattern (in the case of the illustrated mobile terminal, a flat display such as an LCD located under the touch screen, Quot;). According to the implementation, the pattern may be displayed together with other images such as the frame data made up of the pixels obtained from the camera module.

It is also preferable to implement such that the pattern being generated is reset in accordance with the reset instruction of the user, such as pressing of a specific reset key. When the pattern being generated is reset, the pattern generated until then is deleted, and a new pattern is generated according to the pointing operation applied after the reset.

Alternatively, when the user does not receive any other operation from the user other than the pointing operation for generating the pattern, the pattern generator 184 may sequentially delete the portion corresponding to the coordinate values with a predetermined delay time of the pattern . This operation of the pattern generation unit 184 has the same result as that of generating a drawing pattern composed of coordinate values obtained by pointing operation within a predetermined time interval within each predetermined time from each point of time at which a drawing pattern is determined .

According to the implementation, the pattern generation unit 184 may be a software module executed in the control unit of the mobile terminal, an internal hardware module constituting the control unit, or a separate interface device for the touch screen.

The camera module 121 includes a photosensitive sensor such as a CCD sensor or a CMOS sensor. The camera module 121 includes a plurality of pixel arrays that can form a single screen. The camera module 121 is proportional to the intensity and / Can generate an electrical signal.

The frame buffer 187 may be included in the unit hardware (for example, an image sensor chip) constituting the camera module 121 or may be a separate memory or buffer device existing inside or outside the control unit of the mobile terminal, . ≪ / RTI > The frame buffer 187 may temporarily store pixel data constituting a frame at a specific time point.

The image combining unit 186 may combine the two image data in a form in which the pattern input from the pattern generating unit 184 is superimposed on the image corresponding to the frame data input from the frame buffer 187 . Since the above process is a relatively simple signal process, the image combining unit 186 can be easily implemented as a software module or an internal hardware module executed in a control unit of the mobile terminal or other components.

The moving picture converting unit 188 receives data of temporally continuous still images and converts the data into moving picture data. For the moving image generation function of the moving image conversion unit 188, a moving image compression algorithm proposed in the past such as MPEG4 or H.264 can be applied.

The mobile communication module 112 is for forming a wireless communication channel for video communication, and can be applied to a general mobile communication terminal for video communication.

FIG. 8 shows a process of generating moving picture data including a drawing pattern generated by a user using a pointing reception device and transmitting the generated moving picture data to a correspondent terminal.

The above processes can be performed in the control unit of the mobile terminal, and the illustrated method includes: S110 capturing an image; Generating (S120) frame data from pixel light sensitivities obtained by photographing; Detecting a pointing operation (S130); Generating a drawing pattern from the sensed pointing operation (S140); Combining the frame data and the drawing pattern (S150); A step (S160) of generating moving picture data from the combined data; And transmitting the moving picture data to a counterpart terminal through a wireless communication channel (S170).

Steps S110 and S120 may be performed using a camera module and a buffer memory built in the mobile terminal.

Steps S130 and S140 may be performed using a pointing receiving device such as a touch screen built in the mobile terminal.

As shown in the figure, it is preferable that the set of steps S110 and S120, and the set of steps S130 and S140 are simultaneously performed in a human recognizable temporal range. Actually, the computing device performing steps S110 to S140 may sequentially perform the two sets using a plurality of time-division intervals divided into a range not recognizable by a person.

According to the implementation, in steps S130 and S140, it is possible to generate a drawing pattern made up of coordinate values obtained by a pointing operation in a time interval within a predetermined time at each time point for determining a drawing pattern.

According to the implementation, in step S140, when the user's reset operation is sensed, the generated drawing pattern can be deleted.

The user's drawing operation is a process of creating a linear pattern consisting of collection of successive points on two-dimensional coordinates. Thus, the drawing pattern may consist of one or more linear shapes, and areas other than the linear shapes may be in a state where no data is designated. In this case, the step S150 may be performed to obtain a frame image in which the line patterns forming the drawing pattern are superimposed on the frame data.

In step S160, contiguous frame data is compressed into moving picture data using a moving picture compression algorithm such as MPEG4 or H.264.

That is, the semicircle pattern drawn up to that time is outputted to the screen 501 at the first time point of the transmitting terminal and the screen 506 at the first time point of the receiving terminal, The pattern 507 of the second time of the receiving terminal outputs a pattern in which the drawing pattern of the first time point is further added by the user from the first time point to the second time point.

This is because for each video data periodically transmitted from the transmitting-side terminal to the receiving-side terminal for the video call, the drawing pattern created up to that time is included.

After the reset button 520 is pressed for the drawing pattern, as shown in the screens 503 and 508 at the third time point, the drawing pattern is deleted on the display screen of the transmitting mobile terminal and the receiving mobile terminal do.

Thereafter, when the subsequent semicircular line is drawn, the semicircle portion which was originally drawn by the elapsed time is deleted, and the S-shaped pattern remains in the screens 603 and 608 at the third time point shown.

As shown in the figure, a pattern is drawn on the inner video image 810 of the transmitting terminal, and the corresponding drawing pattern is outputted to the remote video image 860 of the receiving terminal. In this case, the user of the transmitting-side terminal draws the pattern in a state in which the pattern drawn by the transmitting-side terminal can be seen in the counterpart terminal, so that it is more convenient.
