CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority under 35 U.S.C. §119 (a) from Korean Patent Application No. 10-2008-130576, filed on Dec. 19, 2008, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. 
       BACKGROUND 
       [0002]    1. Field of the Invention 
         [0003]    The present general inventive concept relates to an input method to control the operation of a mobile apparatus which is held with both hands, and more particularly, to an apparatus which contains a function of photographing an image, such as a camcorder, a camera, and a camera mobile phone. 
         [0004]    2. Description of the Related Art 
         [0005]    Most image photographing apparatuses currently coming into the market may display an object to be photographed on a liquid crystal display (LCD). The image photographing apparatus may also have a user input function using a graphic to improve convenience of user&#39;s manipulation and to provide intuitive input. The user input function using the graphic may display a current state of the apparatus through a display apparatus, and may enable a user to input the user&#39;s intention by manipulating a key or touching a surface of the display apparatus and to manipulate the apparatus according to the user&#39;s intention. 
         [0006]    Such an apparatus which enables the user to input his/her intention by touching the display surface is referred to as a touch screen. The touch screen may be a capacitive touch screen, a resistive touch screen, or an ultrasonic wave touch screen. The capacitive touch screen has opposing glass surfaces coated with a transparent special conductive metal and applies voltage to the corners of a display to generate high frequency. The capacitive touch screen senses a touch point by analyzing a high frequency waveform which is changed when a touch on the display is input. The resistive touch screen has a glass plate or a transparent plate coated with resistive material and a resistance value changes when a touch is input. The resistive touch screen senses a touch point based on the degree of voltage variation. The ultrasonic wave touch screen has a transmitter to emit a sound wave, a reflector to reflect the sound wave, and a receiver to receive the sound wave, all of which are attached to a display surface. The ultrasonic wave touch screen senses a touch point by sensing the advancing path of the sound wave. 
         [0007]    Touch screens may have multi-touch functions of being aware of a plurality of inputs and may be applied to many products. 
         [0008]    However, when a user holds a mobile apparatus with both hands, it is not easy for the user to perform the multi-touch functions with his/her both hands and the user is likely to drop the apparatus.

         [0031]    Adjusting the image-to-be-captured may include at least one of focus-in, focus-out, white balance, exposure control, and LCD control. 
         [0032]    The image-to-be-captured may be adjusted only in a portion of the image corresponding to an area touched by the user. 
         [0033]    The method may further include displaying the adjusted image-to-be-captured on the touch-receptive display. 
         [0034]    The method may further include detecting an input from a user from outside the touch-receptive display. 
         [0035]    The method may further include determining a type of adjustment of the image-to-be-captured based on the user touch on the touch-receptive display and determining a magnitude of adjustment of the image-to-be-captured based on the detected input from the user from outside the touch-receptive display. 
         [0036]    Detecting the input from the user from outside the touch-receptive display may include detecting whether the input from the user is simultaneous with the user touch on the touch-receptive display. 
         [0037]    Detecting the input from the user from outside the touch-receptive display may include detecting whether the input from the user occurs within a predetermined period of time as the user touch on the touch-receptive display. 
         [0038]    The method may further include determining a type of user touch on the touch-receptive display and determining a type of adjustment to the image-to-be-displayed based on the type of user touch on the touch-receptive display.

         [0040]    When it is determined that the user touch is a two-finger simultaneous touch, adjustment of the image-to-be-captured may include zooming into an area defined by the two fingers touching the touch-receptive display. 
         [0041]    When it is determined that the user touch is a two-finger simultaneous touch-and-drag, adjustment of the image-to-be-captured may include zooming into an area defined by the two fingers touching the touch-receptive display by a magnitude defined by a distance at least one of the fingers is dragged across the touch-receptive display. 
         [0042]    Features and/or utilities of the present general inventive concept may also be realized by an image-capture apparatus including a touch-receptive display to display an image-to-be-captured and to receive a user touch, and a controller to adjust the image-to-be-captured based on the user touch. 
         [0043]    The controller may be capable of capturing at least one of a still-frame photograph and a video recording. 
         [0044]    The controller may adjust the image-to-be-captured by at least one of zooming into or zooming out of an area of the image-to-be-captured corresponding to the user touch. 
         [0045]    The touch-receptive display may display the adjusted image-to-be-captured. 
         [0046]    The image-capture apparatus may further include an input device outside the touch-receptive display to receive an input from a user. 
         [0047]    The controller may determine a type of adjustment of the image-to-be-captured based on the user touch on the touch-receptive display, and the controller may determine a magnitude of adjustment of the image-to-be-captured based on the an input from the user from the input device outside the touch-receptive display. 
         [0048]    The controller may determine a magnitude of adjustment of the image-to-be-captured based on the input from the input device outside the touch-receptive display only when the controller determines that the input from the input device is simultaneous with the user touch on the touch-receptive display. 
         [0049]    The controller may determine a magnitude of adjustment of the image-to-be-captured based on the input from the input device outside the touch-receptive display only when the controller determines that the input from the input device occurs within a predetermined period of time as the user touch on the touch-receptive display. 
         [0050]    The controller may determine a type of user touch on the touch-receptive display and may determine a type of adjustment to the image-to-be-displayed based on the type of user touch on the touch-receptive display. 
         [0051]    The type of user touch may be one of a short-duration touch, a long-duration touch, a touch-and-drag, a two-finger simultaneous touch, a two-finger simultaneous touch and drag, and a plurality of short-duration touches in succession.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0070]    Reference will now be made in detail to embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below to explain the present general inventive concept by referring to the figures. 
         [0071]    According to an embodiment of the present general inventive concept shown in  FIG. 1A , a photographic device  100 , or an image-capture apparatus, may include a touch screen  110   a  and a zoom key  140 . The touch screen  110   a  may display an image-to-be photographed or captured. If a user  130  touches a desired portion  135  on a touch screen  110   a,  a guide  120  indicating a range to be zoomed-in is displayed around the touched portion  135 . The guide  120  indicates a range of a still image or a motion image to be photographed, so that the user can photograph a desired range of the still image or the motion image by manipulating a zoom key  140 . 
         [0072]    The zoom key  140  may include a zoom-out portion “W” and a zoom-in portion “T,” and a user may change the dimensions of the guide  120  by manipulating the zoom key  140 . As illustrated in  FIG. 1B , once a user  130  has selected an area to be zoomed-in using the guide  120 , the touch screen  110   d  may display the new image to be photographed or captured according to the user controls. In  FIGS. 1A and 1B , reference numerals  110   a  and  110   d  both refer to a same touch screen (i.e.  110 ) displaying different images. 
         [0073]    Although the guide of  FIG. 1  is of a rectangular shape, this is merely an example. The guide may be displayed in the shape of circle or oval or any other shape. In  FIG. 2 , a guide  210  of a concentric circle shape is illustrated. The guide  120 ,  210  may be adjusted according to an aspect ratio of a still image or a motion image to be displayed, an aspect ratio of a still image or a motion image to be photographed, and an aspect ratio of a touch screen, and its shape may be changed. 
         [0074]    To perform a zooming-in operation according to the displayed guide  120 ,  210 , the user manipulates the zoom key  140  and obtains a zoomed-in image with a desired size. If the manipulation of the zoom-key  140  occurs, the photographing apparatus zooms-in on the touched portion  135  within a selected range using the digital zoom. 
         [0075]    If the photographing apparatus employs a lens capable of adjusting an angle, it may perform the zooming-in operation by adjusting the angle of the lens using the optical zoom. If the photographing apparatus is mounted on a mount which is capable of moving vertically and horizontally, the photographing apparatus may perform the zooming-in operation by moving the mount vertically and horizontally and using the zoom-in function of the lens. 
         [0076]      FIGS. 3A-3D  illustrate results of a still image or a motion image which are displayed according to the guided range if the user performs the zooming-in operation as shown in  FIGS. 1A and 1B . In  FIGS. 3A-3D , as an image is progressively zoomed-in, the range of the image becomes narrower. In other words,  FIG. 3A  illustrates the touch screen  110   a  displaying an image-to-be-captured before zooming.  FIGS. 3B and 3C  illustrate the touch screen  110   b,    110   c  after a user  130  has caused the image-capture device  100  to zoom-in on the selected portion  135  of the image.  FIG. 3D  illustrates the display on the touch screen  110   d  upon completion of the zoom-in process. 
         [0077]      FIGS. 4A-4F  illustrate a menu  420  to control variables to change the properties or characteristics of a touched image. The menu  420  may be displayed, for example, when a long touch is input on a touch screen  410 . 
         [0078]    In  FIG. 4A , a user  430  selects a selection area  435   a  within a portion  410   b  of the touch screen  410  corresponding to a background. In response to the user  430  touch, the menu  420  is displayed, indicating various operations that may be performed on the portion  410   b,  as illustrated in  FIG. 4B . For example, the menu  420  may appear in response to a particular type of touch by the user  430 , such as a long touch, a short touch, or a plurality of touches simultaneously or in succession. 
         [0079]      FIG. 4C  illustrates a user  430  touching an area  435   b  corresponding to the “Focus” operation from the menu  420 . As illustrated in  FIG. 4D , a control bar  440   b  showing the focus level (focus-in and focus-out) is displayed on the upper part and the focus on the touched portion  410   b  is controlled by manipulating the zoom key  440   a  in the same way as when the zooming-in or zooming-out is performed. 
         [0080]    Alternatively, a user  430  may touch an area on the touch screen  410  corresponding to the control bar  440   b  to control the focus of the selected area  410   b.  In other words, a user  430  may adjust characteristics in the selected area  410   b  by adjusting either the control bar  440   b  or the zoom key  440   a.    
         [0081]    The items “White Balance”, “LCD Enhancer”, and “Exposure Value” on the menu are controlled in the same way, and any menu to adjust property values of a still image or a motion image besides the above-described menu can be provided in the same way. 
         [0082]    As illustrated in  FIG. 4E , adjusting the zoom key  440   a  in a first direction toward reference letter “T” causes the selected area  410   b  to lose focus, while the non-selected area  410   a,  in this case corresponding to the foreground, remains in focus. As illustrated in  FIG. 4F , adjusting the zoom key  440   b  in a second direction toward reference letter “W” causes the selected area  410   b  to re-focus. The level of focus may be displayed on the control bar  440   b.    
         [0083]      FIG. 5  is a flowchart illustrating a process of photographing a still image according to an exemplary embodiment of the present general inventive concept. Briefly, it is determined whether or not a touch is input on the touch screen, and, if the touch is input, zooming-in or zooming-out operation is performed according to an external manipulation using the zoom-key. If a photographing key is input, a photographing operation is performed. A detailed description of the method will be provided below. 
         [0084]    As illustrated in  FIG. 5 , in a standby mode (S 510 ), the photographing apparatus determines whether the touch-screen has been touched in operation S 520 . If the user touches the touch screen in operation S 520 -Y and if the user also manipulates the zoom key in the direction of T in operation S 530 -Y, the photographing apparatus performs zooming-in operation with respect to the touched portion such that an idle screen is zoomed-in on the touch screen in operation S 540 . 
         [0085]    On the other hand, if the user touches the touch screen in operation S 520 -Y and also manipulates the zoom key in the direction of W in operations S 530 -N and S 550 -Y, the photographing apparatus performs zooming-out operation with respect to the touched portion such that an idle screen is zoomed-out on the touch screen in operation S 560 . 
         [0086]    It is also possible to display either the zoomed-in state or the zoomed-out state by touching the touch screen. 
         [0087]    After that, if a user manipulates a photographing key to generate a photographing key input in operation S 570 -Y, the idle screen which is currently being displayed on the touch screen is photographed and stored as a still image in operation S 580 . 
         [0088]      FIG. 6  is a flowchart illustrating a process of photographing a motion image according to an exemplary embodiment of the present general inventive concept. Briefly, the presence of a touch is determined when photographing operation is performed by inputting the photographing key, and zooming-in or zooming-out is performed when zoom-in or zoom-out is input through the zoom key, such that an image of a desired range is photographed and the photographing operation is finished through an end key. A more detailed description of the method will be provided below. 
         [0089]    As shown in  FIG. 6 , in a standby mode (S 610 ), if the photographing key is input by the user in operation S 620 -Y, a motion image is photographed in operation S 630 . 
         [0090]    After that, if the user touches the touch screen in operation S 640 -Y and manipulates the zoom-key in the direction of T in operation S 650 -Y, the photographing apparatus performs zooming-in operation with respect to the touched portion such that an idle screen is zoomed in on the touch screen and is photographed as a motion image in operation S 660 . 
         [0091]    On the other hand, if the user touches the touch screen in operation S 640 -Y and manipulates the zoom key in the direction of W in operation S 670 -Y, the photographing apparatus performs zooming-out with respect to the touched portion such that an idle screen is zoomed-out on the touch screen and is photographed as a motion image in operation S 680 . 
         [0092]    After that, if the end key is input by the user in operation S 690 -Y, the photographing apparatus finishes photographing the motion image in operation S 695 . 
         [0093]    In  FIGS. 5 and 6 , touching the screen and inputting the zoom-key may occur simultaneously or in sequence according to user&#39;s selection. 
         [0094]    Also, in this embodiment, the touched portion is zoomed-in or zoomed-out by manipulating the zoom key, but this is merely an example. The technical idea of the present general inventive concept can be applied to the case in which a display status is changed according to a key manipulation with respect to a touched portion. 
         [0095]      FIGS. 7 and 8  are flowcharts illustrating a controlling process if a long touch is input on a screen.  FIG. 7  illustrates a controlling process if a long touch is input on a screen while a still image is photographed, and  FIG. 8  illustrate a controlling process if a long touch is input on a screen while a motion image is photographed. 
         [0096]    If a short touch is input and the zoom key is input, the zooming-in or zooming-out is performed according to the manipulation direction of the zoom key as shown in  FIGS. 5 and 6 . However, if a long touch is input, the photographing apparatus identifies which area is touched (object area or background area) and displays a control menu regarding the selected area so that the user can select a control variable to change. A detailed description of the method will be provided below. 
         [0097]    The controlling process if a long touch is input on a screen while a still image is photographed will be described in detail with reference to  FIG. 7 . 
         [0098]    As shown in  FIG. 7 , in a standby mode (S 710 ), if the user inputs a long touch on the touch screen in operation S 720 -Y, the photographing apparatus automatically selects the touched area as a target area to be processed in operation S 730 . 
         [0099]    More specifically, in operation S 730 , it is determined whether the touched area indicates an object or a background and the touched area is automatically selected as a target area. Specifically, 1) if the touched area indicates an object, an area including the object is selected as a target area to be processed, and 2) if the touched area indicates a background, an area including the background is selected as a target area to be processed. Referring to  FIGS. 4A-4F , the background  410   b  is touched by the user  430  and the area including the background  410   b  is selected as a target area to be processed. 
         [0100]    Next, the photographing apparatus displays a pop-up menu on the display of the touch screen in operation S 740 . The pop-up menu contains a list of menu items which are used to input a command to change a setting value regarding the selected area. 
         [0101]    If one of the menu items contained in the pop-up menu is selected in operation S 750 -Y, the photographing apparatus displays a controller to adjust the setting value (menu item value) regarding the selected menu item on the display of the touch screen in operation S 760 . 
         [0102]    The menu item is selected from the pop-up menu by user&#39;s touch on it in operation S 750 . Also, the user may adjust the menu item value using the controller displayed in operation S 760 . 
         [0103]    If the menu item “Focus” is selected in operation S 750 , a control bar which is a controller indicating the focus level is displayed. Therefore, the user can photograph an image while adjusting the focus value using the zoom-key, which was described with reference to  FIGS. 4A-4F . 
         [0104]    If adjusting the menu item value is finished in operation S 770 -Y, the photographing apparatus sets the selected target area according to the adjusted menu item value in operation S 780 . 
         [0105]    Next, if the photographing key is input by the user in operation S 790 -Y, an idle screen displayed on the touch screen at that time is photographed and is stored as a still image in operation S 795 . 
         [0106]    Hereinafter, a controlling process if a long touch is input on the screen while a motion image is photographed will be described with reference to  FIG. 8 . 
         [0107]    As shown in  FIG. 8 , in a standby mode (S 805 ), if the user inputs the photographing key in operation S 810 -Y, a motion image is photographed in operation S 815 . 
         [0108]    After that, if a long touch on the touch screen is input by the user in operation S 820 -Y, the photographing apparatus automatically selects the touched area as a target area to be processed in operation S 825 . Operation S 825  is similar to operation S 730  of  FIG. 7  and thus detailed description thereof will be omitted. 
         [0109]    Next, the photographing apparatus displays a pop-up menu on the display of the touch screen in operation S 830 . The pop-up menu contains a list of menu items which are used to input a command to change a setting value regarding the selected area. 
         [0110]    If one of the menu items contained in the pop-up menu is selected in operation S 835 -Y, the photographing apparatus displays a controller to adjust a setting value (menu item value) regarding the selected menu item on the display of the touch screen in operation S 840 . 
         [0111]    Selecting the menu item in operation S 840  may be performed by user&#39;s touch on a desired menu item displayed on the touch screen. Also, the user may adjust the menu item value using the controller displayed in operation S 840 . 
         [0112]    If adjusting the menu item is finished in operation S 845 -Y, the photographing apparatus sets the selected area according to the adjusted menu item value in operation S 850 . 
         [0113]    Next, if an end key is input by the user in operation S 855 -Y, the photographing apparatus finishes photographing the motion image in operation S 860 . 
         [0114]    If a long touch is input, it is possible to determine which area is selected and display a menu to change a photographing control variable regarding the selected area as described above. However, it is also possible to change a photographing control variable regarding the entire image to be photographed without determining which area is selected. 
         [0115]      FIG. 9  is a block diagram illustrating a photographing apparatus  100  according to an exemplary embodiment of the present general inventive concept. As shown in  FIG. 9 , a photographing apparatus  100  includes a photographing unit  910 , a signal processor  920 , a CODEC  930 , a storage unit  940 , a menu generator  950 , a touch LCD  960 , a controller  970 , and a key input unit  980 . 
         [0116]    The photographing unit  910  converts an image to be photographed, which is incident through a lens and is formed on an optical surface, into an image signal. 
         [0117]    The signal processor  920  performs signal-processing with respect to the image signal generated by the photographing unit  910 . Representative examples of the signal-processing performed by the signal processor  920  are digital zoom and auto white balance (AWB). 
         [0118]    The CODEC  930  compresses the image signal signal-processed by the signal processor  920  and stores it to the storage unit  940 , or decompresses the compressed image signal stored in the storage unit  940  and provides it to the menu generator  950 . 
         [0119]    The menu generator  950  generates a menu and adds the menu to the image. The image provided to the menu generator  950  may include at least one of 1) an image which has been photographed by the photographing unit  910  and signal-processed by the signal processor  920 , and 2) an image which has been decompressed by the CODEC  930 . 
         [0120]    The touch LCD  960  displays the image to which the menu is added by the menu generator  950 . If no menu is added by the menu generator  950 , the touch LCD  960  displays only the image. 
         [0121]    The touch LCD  960  may serve as a means of receiving a touch manipulation from the user. 
         [0122]    The controller  970  controls the photographing unit  910 , the signal processor  920 , and the menu generator  950  according to the user&#39;s manipulation input through the touch LCD  960  and the key input unit  980 . More specifically, the controller  970  performs the processes described with reference to  FIGS. 5 to 8  and also controls the photographing unit  910 , the signal processor  920 , and the menu generator  950 , if necessary. 
         [0123]      FIG. 10  illustrates a photographing unit  910 , or an image capture unit, corresponding to the photographing unit of  FIG. 9 . The photographing unit  910  may include a lens, or lenses,  1010  to receive light corresponding to an image-to-be-captured and a signal generator  1020  to convert the light to electrical signals. The photographing unit  910  may further include a lens position adjustment unit  1030  to adjust the position of the lens  1010 . For example, the lens position adjustment unit  1030  may be controlled based on a user selection to focus on one portion of an image-to-be-displayed, and may in turn control the position of the lens  1010 . 
         [0124]    The lens  1010  may be adjusted by a motor, a piezo-electric material, or any other device capable of changing a position or orientation of the lens  1010 . 
         [0125]    While the lens position adjustment unit  1030  may manipulate the lens  1010  based on a user input to adjust a characteristic of an image-to-be-captured, the characteristic of the image-to-be-captured may also be adjusted by the controller  970  and signal processor  920  of  FIG. 9 . For example, the controller  970  may cause the signal processor  920  to manipulate the electrical signals corresponding to the image-to-be-captured so that a portion of the image-to-be-captured is out of focus. 
         [0126]      FIG. 11  illustrates a photographic device  100  connected to an adjustable mount  1110 . Light from an image may enter the photographic device from a front side, and the image-to-be-captured may be displayed on a touch-screen, or touch-receptive display  110 , on the same side or another side of the photographic device  100 . The zoom key  140  may also be used to manipulate the image-to-be-captured. 
         [0127]    The adjustable mount  1110  may receive signals from the photographic device  100  to move the adjustable mount in any of directions x, y, and z based on a user input. The mount may also rotate around any of the axes x, y, z in directions α, θ, and β, respectively. For example, if a user zooms in on a portion of the image-to-be-captured displayed in a lower corner of the display  110 , the mount  1110  may physically move to better display the selected portion. The movement of the mount  1110  may be combined with movement of the lens  1010  of  FIG. 10 , or it may occur independently of the lens  1010 . 
         [0128]    The mount  1110  may be motorized so that upon receiving command signals from the photographic device  100 , it can change the position and/or orientation of the photographic device  100  without direct intervention by a user. 
         [0129]    The present general inventive concept can also be embodied as computer-readable codes on a computer-readable medium. The computer-readable medium can include a computer-readable recording medium and a computer-readable transmission medium. The computer-readable recording medium is any data storage device that can store data as a program which can be thereafter read by a computer system. Examples of the computer-readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, DVDs, magnetic tapes, floppy disks, and optical data storage devices. The computer-readable recording medium can also be distributed over network coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. The computer-readable transmission medium can transmit code through carrier waves or signals (e.g., wired or wireless data transmission through the Internet). Also, functional programs, codes, and code segments to accomplish the present general inventive concept can be easily construed by programmers skilled in the art to which the present general inventive concept pertains. 
         [0130]    Although various example embodiments of the present general inventive concept have been illustrated and described, it will be appreciated by those skilled in the art that changes may be made in these example embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
