Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The mobile terminal 100 according to the embodiment of the present invention having at least one of the configurations described above can take a subject through the camera 121 provided in the mobile terminal 100. [ The display unit 151 of the mobile terminal 100 may display the first graphic object corresponding to the first focus area on the preview screen acquired through the camera 121. [ Here, the first focus area may be an area automatically set according to the auto focusing function of the camera 121. Further, the first graphic object may be an image representing a focus area corresponding to the auto focusing function, for example, a focusing box image.

The user input unit 123 of the mobile terminal 100 can select a plurality of subjects on the output preview screen based on the touch input on the preview screen output to the display unit 151. [ When a plurality of subjects are selected in the preview screen, the control unit 180 of the mobile terminal 180 sets a region corresponding to the selected plurality of subjects as a second focus region in response to a predetermined input signal being sensed . Here, the second focus area may be a region in which a plurality of subjects selected through the user input unit 123 are output. At this time, when the selected subject moves or moves, the controller 180 can automatically track the selected subject and change the second focus area.

In addition, when the second focus region is set, the controller 180 may apply a depth sense visually distinguishable from the first focus region to the set second focus region. Here, the depth sense may be visually distinguished by displaying the thickness of the boundary line of the subject corresponding to the second focus area differently, or by differently displaying the shape, color, size, blurring process of the boundary area, .

In addition, the controller 180 may generate an out-focusing image for the preview screen based on at least one of the first and second focus areas. That is, the controller 180 may generate an out-focusing image only on the basis of the first focus area corresponding to the auto focusing function (hereinafter, referred to as a 'first image'), An out-focusing image may be generated based on a second focus area corresponding to a subject (hereinafter referred to as a 'second image'). Here, out-focusing refers to a technique in which, when a specific scene is photographed by a camera, the background is photographed except the focused area to make a specific subject appear more clearly. The out-focusing image indicates an image to which the out-focusing is applied to the image to be shot / photographed.

As described above, when the focus of the image is set based on a plurality of subjects selected by the user on the preview screen, a plurality of subjects selected according to the intention of the user can be photographed more clearly

2 is a flowchart illustrating a method of generating an out-focusing image based on a plurality of focus areas selected by a user on a preview screen according to an exemplary embodiment of the present invention. 3 is a conceptual diagram for explaining the flow chart of Fig.

2, when the mobile terminal 100 according to the embodiment of the present invention enters the photographing mode, the preview screen obtained through the camera 121 is displayed on the display unit 151, The first graphic object corresponding to the first focus area is displayed (S210).

Here, the first focus area is an area automatically set according to the auto focusing function of the camera 121, and the first graphic object corresponds to the image indicating the position of the first focus area. 3 (a), when the mobile terminal 100 enters the photographing mode, the focusing box 315 is placed in one area of the preview screen 301, for example, the central area 310, Can be output. At this time, the user can change the first focus area by moving the outputting focus box 415 through the touch-and-drag input.

When the preview screen is thus output, the mobile terminal 100 can select a plurality of objects included in the preview screen based on the touch input to the preview screen (S220).

Here, the plurality of subjects included in the preview screen include a plurality of subjects, for example, a human face, an object, a specific background, and regions included in the preview screen, and pinch- Or a pinch-out touch input so as to include a subject included in the enlarged / reduced displayed image, or one area of the subject.

The touch input to the preview screen is a touch input of a preset method. For example, the touch input may be a touch or a long touch input for tapping a region in which a subject to be selected is output from the preview screen for a predetermined number of times, It can be a touch and drag input that draws a line.

For example, referring to FIG. 3B, when a user performs a long touch input on specific objects 320 and 330 on the preview screen output to the display unit 151, the corresponding objects 320 and 330 Are selected so that a predetermined function can be applied. Then, the mobile terminal 100 recognizes and tracks the subjects 320 and 330 and outputs an indication corresponding to the selection, for example, a shading effect. In addition, although not shown, a predetermined graphic object indicating the focus area may be displayed in the selected subjects 320 and 330. [ The graphic object at this time may be the same as or different from the graphic image corresponding to the above-described auto focusing function.

Subsequently, when a predetermined input signal is detected while a plurality of subjects are selected, the mobile terminal 100 sets a region corresponding to the selected plurality of subjects as a second focus region. Then, in step S230, a depth sensation visually distinguishable from the first focus area is applied to the set second focus area.

Here, the preset input signal means that the setting of the "focus area" is selected in the context menu including the functions applicable to the subjects in response to the selection of the plurality of subjects. For example, as shown in FIG. 3 (c), in response to the selection of the subjects 320 and 330 in FIG. 3 (b), one area of the display unit 151, And a menu window 350 is displayed in the lower right area. When the user selects the 'Select All' item 353 or the '2 Focus' item 352 in the corresponding menu window 350 through the touch input, the subjects 320 and 330 are set as the focus areas. When the 'Select All' item 353 is selected, the area 310 'that is automatically set in focus according to the auto focusing function is displayed so that the first depth sense is felt, and the subjects 320' , 330 "can be displayed so that the second depth feeling is felt.

Here, as described above, the thickness of the boundary line of the subject corresponding to the focus area is displayed differently, or the blur processing of the subject shape, color, size, and boundary area is displayed differently, As shown in FIG.

Here, the first and second depth senses are different from each other, and if there is no other setting, the second depth sensation corresponding to the focus area set by the user selection will be displayed to be deeper.

When the first and second focus areas are set as described above, the mobile terminal 100 proceeds to step S240 of generating an out-focused image for the preview screen based on the first and second focus areas. Here, the generated out-focusing image includes both the still image and the moving image.

In addition, when generating the out-of-focus image, the controller 180 may control the sharpness of the selected plurality of subjects to be higher than the sharpness of the first focus area corresponding to the auto-focusing function.

For example, as shown in (d) of FIG. 3, the color of the background area excluding the subjects 320 "and 330" selected through the touch input and the subject area 310 " By sharpening the sharpness, resolution, and the like, it is possible to obtain the image 301 'to which the out-focusing effect corresponding to the user's intention is applied.

3 (d), a menu window for applying the out-focusing on the preview screen of FIG. 3 (c) may be output to one area of the display unit 151. [ Alternatively, when a photographing signal is applied on the preview screen of FIG. 3 (c), it is possible to automatically generate an image to which the out-focusing effect is applied.

The controller 180 may output a second graphic object along a boundary line of a plurality of subjects so that a depth sense visually distinct from the first focus area appears in a plurality of selected subject areas. Here, the second graphic object may be an image that is visually emphasized rather than a graphic image formed on a boundary line of the first focus area or the first focus area. For example, the second graphic object may be an image in which a shadow effect or a thick boundary line processing effect is applied to each boundary line of a plurality of selected objects.

In addition, the control unit 180 may display an image out-focused in a semitransparent form on the preview screen in an overlapped form. In this case, the control unit 180 may be configured to determine whether to generate an out-focusing image at the time of shooting based on user input.

In addition, in the embodiment of the present invention, it is preferable that the out-focusing image is generated as a single photographed image. However, if it is necessary to perform out-focusing on the original image corresponding to the plurality of focus areas and the out- Images may be respectively generated.

In the foregoing, a method of generating an out-focusing image based on a subject corresponding to the auto focusing function and a plurality of subjects selected by the user has been described. Hereinafter, a method of displaying an out-focusing image generated based on a plurality of focus areas will be described.

In this regard, FIG. 4 is a conceptual diagram for explaining a method of displaying a photographed image according to various focus areas selected by a user, according to an embodiment of the present invention.

First, when generating the out-focusing image, the mobile terminal 100 according to an exemplary embodiment of the present invention includes a first image to which an out-focusing effect is applied based on a first focus region, And a second image to which the out-focusing effect is applied as a reference. In addition, the controller 180 may generate a third image to which the out-focusing effect is applied based on only the second focus region.

Also, the control unit 180 may output at least one of the plurality of images to the display unit 151 or convert the previously output image to another image based on the input control command.

To this end, the memory 170 of the mobile terminal 100 stores a first image photographed based on at least the first focus region and a second image photographed based on the first and second focus regions.

In response to the execution of the image viewing function, in a state in which the first image is output to at least one area of the display unit 151, the controller 180 controls the display unit 151 such that the touch input is continuously And in response, switch the first image to the second image or output the first and second images together.

For example, referring to FIG. 4, in a state where the out-focusing image 401 generated based on the first focus area is outputted to the display unit 151 as shown in FIG. 4 (a) When a predetermined touch input, for example, a short-touch, is applied to the photographic image 401, the out-focusing image 402 generated based on the second focus area is displayed as shown in FIG. 4B. When a short-touch is applied to the displayed out-focusing image 402, the out-focusing image 403 generated based on the first and second focus areas is output as shown in FIG. 4C, If there is no image, the process returns to FIG. 4 (a) and the out-focusing image 401 generated based on the first focus area is output again. At this time, although not shown, information indicating a focus object corresponding to the out-focusing image outputted may be displayed in one area of the display unit 151. [

Also, although not shown, the first image and the second image may be displayed in the first area and the second area of the display unit 151, respectively. Also, in this case, the controller 180 can easily control the image editing using any one of the two images.

FIG. 5 is a conceptual diagram for explaining a method of adjusting a degree of blur of a background region based on a focus region selected by a user according to an embodiment of the present invention. That is, in the embodiment of the present invention, by adjusting the degree of blurring of the background area of the selected focus area, it is possible to obtain an image to which the out-focusing effect is applied differently.

To this end, when a preview screen is displayed on the display unit 151 of the mobile terminal 100, an indicator icon related to execution of the out-focusing function may be output to one area of the preview screen.

Here, the indicator icon is normally hidden, but may be implemented to appear in one area of the display unit 151 when a touch is applied to the preview screen. 5 (a), the long bar-shaped control bar 550 including the moving device 555 may be mounted on the display unit 151, And output to the lower region of FIG.

Then, the controller 180 may adjust the sharpness of the background areas of the first and second focus areas based on the touch input applied to the output indicator icon.

Specifically, the controller 180 increases the difference between the sharpness of the first and second focus areas and the sharpness of the background area in response to the touch input applied to the output indicator icon being dragged in the first direction . Accordingly, it is possible to obtain an image in which the out-focusing effect is increased.

For example, in FIG. 5A, the user moves the moving element 555 of the control bar 550 displayed on the display unit 151 in the right direction to display an out-focusing effect on the displayed preview screen 501 Can be further increased. Accordingly, an image 502 in which the background area becomes more blurred as shown in FIG. 5 (b) is displayed.

In addition, in response to the touch input applied to the output indicator icon being dragged in the second direction, the controller 180 may reduce the difference between the sharpness of the first and second focus areas and the sharpness of the background area . Accordingly, an image with reduced out-focusing effect can be obtained.

For example, in FIG. 5B, the user moves the moving element 555 of the control bar 550 displayed on the display unit 151 to the left side, The effect can be further reduced. Accordingly, an image 503 in which the background area becomes more distinct as shown in FIG. 5 (c) is displayed.

Meanwhile, although not shown, the controller 180 may move the moving element 555 of the control bar 550 to display a corresponding value of the out-focusing effect as text or image.

6 is a conceptual diagram for explaining a method of selecting and canceling a focus area on a preview screen based on a touch input according to an embodiment of the present invention. That is, an embodiment for easily setting and canceling a focus area for a plurality of subjects will be described.

The mobile terminal 100 controls the display unit 151 to output a preview image for photographing when it is detected that the user enters the photographing mode. In this way, in a state in which the preview screen for photographing preparation is output, the control mode corresponding to the execution of the function for setting a plurality of subjects as the focus area can be entered.

In this case, the user input unit 123 can select the subject in response to the first touch input being applied to the subject included in the output preview screen. In response to the second touch input being applied to the subject after the first touch input, the selection of the subject can be canceled. At this time, the first touch input and the second touch input may be the same touch input. That is, the second touch input may be one in which the first touch input is continuously performed.

The control unit 180 may display different graphic images of the subject corresponding to the selection and cancellation.

For example, in the preview screen 601 shown in FIG. 6 (a), when a user selects a specific subject 620 through a touch input, the graphic image of the selected subject, as shown in FIG. 6 (b) For example a dark image 620 ", and information indicating that it has been selected, e.g., a 'select' message 625, is displayed over the selected object.

6 (b), when the user touches the selected object 620 "again, the selection is canceled and the graphic image of the selected object as shown in FIG. 6 (c) And is changed back to the bright image 620. Information indicating that the selection is canceled, for example, a 'cancel' message 625 ', is displayed on the selected object.

In the above, embodiments in which the same focus is applied to a plurality of subjects selected by the user have been described. However, even when a plurality of subjects are selected, a user may want to output a more distinct image to a specific subject and output a clearer resolution than the one that is sharp to another subject. In this case, the user can acquire an image that more clearly reflects the intention of the user.

7 is a conceptual diagram for explaining a method of adjusting the sharpness of a subject corresponding to a selected focus area using a thumbnail image according to an embodiment of the present invention.

First, a preview screen is displayed on the display unit 151, and when a plurality of objects are selected from the preview screen through the user input unit 123, the controller 180 of the mobile terminal 100 according to the embodiment of the present invention A thumbnail image corresponding to the selected plurality of subjects can be displayed in one area of the preview screen.

Here, the thumbnail image corresponding to the selected subject does not necessarily have to be the same as the shape of the subject, and an image having the same color as the color appearing on the selected subject is sufficient.

For example, as shown in FIG. 7A, when a plurality of subjects 720 and 730 are selected on the preview screen 701 through a touch input, one area of the display unit 151, for example, Thumbnail images 771 and 772 corresponding to the selected object are displayed in the right region 770. [ At this time, the display order of the thumbnail images 771 and 772 corresponds to the selection order of the corresponding subjects 720 and 730. That is, in the preview screen 701 of FIG. 7A, it can be seen that the second subject 720 is selected after the first subject 730 is selected.

In this manner, when a thumbnail corresponding to the selected subject is displayed, the control unit 180 can output the selection indication to the corresponding subject in response to the selection of the thumbnail image. For example, if a touch is applied to the first thumbnail image 771 in (b) of FIG. 7, a region corresponding to the first thumbnail image 771, or a region in which the subject 730 corresponding to the first thumbnail image 771 is displayed, Effect is output.

In addition, the controller 180 may adjust the sharpness of the corresponding object based on the number of times of the touch input applied to the selected thumbnail image. Specifically, when the touch input applied to the selected thumbnail image increases to a reference value, the controller 180 increases the sharpness of the corresponding object and decreases the sharpness of the corresponding object when the touch input is applied to exceed the reference value .

For example, referring to FIGS. 7B and 7C, when the user performs a touch input on the first thumbnail image 771 below the reference value (for example, three times to five times), the first thumbnail The image 771 is changed to a darker image 771 ", and the sharpness of the subject 730 corresponding to the changed first thumbnail image 771 " is increased. At this time, the degree of change of the sharpness of the first thumbnail image 771 " and the corresponding subject 730 is determined in proportion to the number of times of touch input. Also, although not shown, the first thumbnail image 771 or 771 " A predetermined animation effect may be displayed every time a touch is applied, for example, a smiling or crying facial expression change in the case of a human face image.

On the other hand, when the user performs a touch input in the second thumbnail image 772 exceeding the reference value, the second thumbnail image 772 is changed to a brighter image 772 ", and the changed second thumbnail image 772 Quot;) of the subject 720 is also reduced. At this time, the reduction of the sharpness will mostly be a decrease in resolution, but the present invention is not limited to this case, but the boundary line of the subject may be represented by a dotted line or a translucent effect may be applied.

The above-described mobile terminal and the mobile terminal equipped with the cover are not limited in configuration and method of the above-described embodiments, but the embodiments can be applied to all or a part of each embodiment May be selectively combined.

According to the mobile terminal and the control method thereof, the focus of the image is set on the basis of a plurality of subjects selected by the user on the preview screen, so that a plurality of subjects Can be more clearly photographed. In addition, since the sharpness of a plurality of subjects selected by a user can be adjusted differently using a thumbnail image, it is possible to acquire an image more clearly matching various user's needs.

Furthermore, the present invention can be embodied as computer-readable code on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
