It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.
The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.
It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.
The terms such as “first” and “second” used in various embodiments are used to distinguish various elements from one another regardless of an order or importance of the corresponding elements. Accordingly, the order or importance of the elements is not limited by these terms. For example, a first element may be named a second element without departing from the scope of right of various embodiments of the present invention, and similarly, a second element may be named a first element.
It will be understood that, when an element (e.g., a first element) is “(operatively or communicatively) coupled with/to” or “connected to” another element (e.g., a second element), the element may be directly coupled with/to another element, and there may be an intervening element (e.g., a third element) between the element and the other element. To the contrary, it will be understood that, when an element (e.g., a first element) is “directly coupled with/to” or “directly connected to” another element (e.g., a second element), there is no intervening element (e.g., a third element) between the element and the other element.
All of the terms used herein including technical or scientific terms have the same meanings as those generally understood by an ordinary skilled person in the related art unless they are defined otherwise. The terms defined in a generally used dictionary should be interpreted as having the same meanings as the contextual meanings of the relevant technology and should not be interpreted as having ideal or exaggerated meanings unless they are clearly defined in the various embodiments. According to circumstances, even the terms defined in the embodiments should not be interpreted as excluding the embodiments of the present disclosure.
Various embodiments will be explained in detail with reference to the accompanying drawings.
FIGS. 1A and 1B are views to illustrate an example of a configuration of a display of a user terminal apparatus according to various embodiments of the present disclosure.
Referring to FIG. 1A, the left view shows the front surface of a user terminal apparatus 100, and the right view shows the rear surface of the user terminal apparatus 100. A front display is disposed on the front surface of the user terminal apparatus 100, and a rear display and a camera are disposed on the rear surface of the user terminal apparatus 100. The front display and the rear display may be connected with each other, and the rear display may be smaller than the front display. However, this should not be considered as limiting, and the front display and the rear display may have the same size. In addition, the camera may be disposed on the front surface of the user terminal apparatus 100. The front display will be explained as a main display area 10 and the rear display will be explained as a sub display area 20.
Referring to FIG. 1B, the left view is a front view showing the entire display in which the main display area 10, the sub display area 20, and a round display area 30 are connected with one another, and the right view is a rear view of the entire display.
The sub display area 20 may extend from one side of the main display area 10 and may be disposed on at least one area of the rear surface of the user terminal apparatus 100. In particular, the sub display area 20 may extend from the top of the main display area 10 to be bent. The bent area may have a curved shape, but is not limited to this and may form an angle according to the type of the display.
The round display area 30 is an area for connecting the main display area 10 and the sub display area 20. As described above, the round display area 30 may have a curved shape or an angular shape. The round display area 30 may be distinguished from the main display area 10 and the sub display area 20 by boundary lines 30-1, 30-2.
The boundary lines 30-1, 30-2 shown in FIG. 1B are merely an example and may be changed. In addition, the boundary lines 30-1, 30-2 may be determined by a manufacturer at the time of manufacturing, and may be changed by a user. In response to the boundary lines 30-1, 30-2 being changed, the sizes of the main display area 10, the sub display area 20, and the round display area 30 may be changed and the size of a content displayed on each area may be changed.
In FIGS. 1A and 1B, the display encloses the upper side of the user terminal apparatus 100. However, the display may enclose any one of the lower side, the left side surface, and the right side surface of the user terminal apparatus 100. In addition, the display may enclose a plurality of side surface other than a single side surface.
The display may enclose a touch pad, and the display and the touch pad may be implemented in the form of a touch screen by forming a mutual layer structure. In this case, the touch pad is also bent similarly to the display and thus a touch input may be inputted opposite to what the user thinks. For example, it may be determined that there is a difference in the touch area but the touch is made in the same direction in response to the user dragging from a certain point of the main display area 10 to an upper point and in response to the user dragging from a certain point of the sub display area 20 to an upper point. However, since the touch pad is bent, the touch pad may receive the input in the opposite direction to the real input in response to the user dragging from a certain point of the main display area 10 to an upper point and in response to the user dragging from a certain point of the sub display area 20 to an upper point. Therefore, the user terminal apparatus 100 may be set to recognize the direction of a touch input at a certain area as the opposite direction. This departs from the scope of the present disclosure and thus a detailed description thereof is omitted.
Since the main display area 10, the sub display area 20, and the round display area 30 are connected with one another, various sensors and a receiver may be provided on the side surface or lower portion of the user terminal apparatus 100. In particular, a directional receiver may be provided. Alternatively, the receiver may be provided on an integral cover which may interwork with the user terminal apparatus 100. In response to the receiver being provided on the lower portion, a processor 130 may reverse the top and bottom of an image and display the image while the user is talking on the phone.
First, the present disclosure will be explained on the assumption that the sub display area 20 has a structure extending from the main display area 10 through the round display area 30 of the curved shape, and the camera is disposed on the rear surface of the user terminal apparatus 100. Additionally, various embodiments will be expanded and described when the display has other configurations and the location of the camera is changed.
In addition, the direction of the main display area 10 and the sub display area 20 going toward the round display area 30 will be explained as being upward from the user terminal apparatus 100, and the opposite direction will be explained as being downward. The left side and the right side will be explained with reference to a display area which is viewed by the user. Accordingly, the left side and the right side when the user views the main display area 10 are reversed when the user views the sub display area 20.
FIG. 2A is a block diagram illustrates a configuration of a user terminal apparatus according to an embodiment of the present disclosure.
Referring to FIG. 2A, a user terminal apparatus 100 includes a display 110, a camera 120, and a processor 130.
FIG. 2A illustrates overall elements of the user terminal apparatus 100 when the user terminal apparatus 100 is provided with various functions such as a display function, a control function, and the like. Accordingly, some of the elements shown in FIG. 2A may be omitted or changed and other elements may be added according to an embodiment.
The display 110 may include a main display area 10 which is disposed on the front surface of the user terminal apparatus 100, a sub display area 20 which extends from one side of the main display area 10 and is disposed on at least one area of the rear surface of the user terminal apparatus 100, and a round display area 30 for connecting the main display area 10 and the sub display area 20. However, this should not be considering as limiting. For example, the sub display area 20 may be configured to enclose the entire rear surface of the user terminal apparatus 100.
The terms “front surface” and “rear surface” are used for convenience of explanation and are not limited by the meaning thereof. For example, the front surface and the rear surface may refer to one side surface and the other side surface regarding a specific electronic device. In the above-described explanation, the display 110 extends from one side of the main display area 10. However, this should not be considered as limiting. For example, the display 110 may extend from all side surfaces of the main display area 10 and cover the entire user terminal apparatus 100.
The sub display area 20 of the display 110 may extend from the upper side of the main display area 10 to be bent and may be disposed on the upper area of the rear surface. For example, a connection part between the main display area 10 and the sub display area 20 may be formed in the shape of “U” and have a curved line when the main display area 10 and the sub display area 20 are viewed from the side. However, this should not be considered as limiting. The connection part between the main display area 10 and the sub display area 20 may be formed in the shape of a squared “C” and have an angle of 90° when the main display area 10 and the sub display area 20 are viewed from the side. In addition, various connection parts may be formed based on the type of the user terminal apparatus 100.
The display 110 may display various user interfaces (UIs) under the control of the processor 130. For example, the display 110 may display a live view, a gallery application, an animation, and the like.
The display 110 may display different contents on the main display area 10, the sub display area 20, and the round display area 30 under the control of the controller 130. For example, the display 110 may display a moving picture on the main display area 10, an image on the sub display area 20, and a UI for transmitting a message on the round display area 30.
In addition, the display 110 may display a content by interlocking at least two of the main display area 10, the sub display area 20, and the round display area 30. For example, the display 110 may display a moving picture on the main display area 10 and display a UI for controlling the moving picture on the sub display area 20. In addition, the display 110 may display a UI for providing a function unrelated to the moving picture on the round display area 30.
In addition, the display 110 may display the same content on at least two of the main display area 10, the sub display area 20, and the round display area 30. For example, the display 110 may display the same content on the main display area 10 and the sub display area 20 and may display a separate content on the round display area 30.
The display 110 may be implemented by using a liquid crystal display (LCD) panel, an organic light emitting diodes (OLED) display, a plasma display panel (PDP), and the like, but is not limited to these. In addition, the display 110 may be implemented by using a transparent display, a flexible display, and the like, according to circumstances.
The camera 120 is configured to photograph a still image or a moving picture under the control of the user. The camera 120 may photograph a still image at a specific time or may continuously photograph a still image. The camera 120 provides the acquired image to the display 110, and a live view may be displayed on at least one of the main display area 10 and the sub display area 20. The camera 120 may photograph the user or a background image according to the orientation of the user terminal apparatus 100. The camera 120 may include a plurality of cameras such as a front camera and a rear camera.
The camera 120 includes a lens, a shutter, an aperture, a solid state imaging device, an analog front end (AFE), and a timing generator (TG). The shutter adjusts a time at which light reflected from a subject enters the user terminal apparatus 100, and the aperture adjusts an amount of light entering the lens by mechanically increasing or reducing the size of an opening through which light enters. The solid state imaging device outputs an image generated by photo-charge as an electric signal when the light reflected from the subject accumulates as photo-charge. The TG outputs a timing signal to read out pixel data of the solid state imaging device, and the AFE samples and digitizes the electric signal outputted from the solid state imaging device.
The processor 130 may control the overall operation of the user terminal apparatus 100.
The processor 130 may control to display a live view acquired through the camera 120 on one of the main display area 10 and the sub display area 20, and display the live view on the other one of the main display area 10 and the sub display area 20 in response to the orientation of the user terminal apparatus 100 being changed. The processor 130 may determine whether the orientation of the user terminal apparatus 100 is changed using a gravity sensor, an acceleration sensor, a gyro sensor, and the like. In addition, the processor 130 may determine whether the orientation of the user terminal apparatus 100 is changed by analyzing the live view acquired by the camera 120. However, this should not be considered as limiting. The processor 130 may change the area to display the live view by moving or shaking in a specific direction, in addition by changing the orientation of the user terminal apparatus 100.
The processor 130 may display the live view and additionally may display a guide line. In addition, the processor 130 may display a graphical UI (GUI) for executing a gallery application, a GUI for executing an image correction application, and the like, in addition to a GUI for photographing.
The processor 130 may display the live view on the main display area 10 and may not provide information on the sub display area 20. In response to the orientation of the user terminal apparatus 100 changing, the processor 130 may display the live view on the sub display area 20 and may not provide information on the main display area 10. The information may not be provided in various ways. For example, power may not be supplied to the display 110 or black is displayed on the display 110.
The processor 130 may activate a touch function of the main display area 10 while displaying the live view on the sub display area 20 without providing information on the main display area 10. In response to detecting a user touch from the main display area 10, the processor 130 may photograph and store an image.
In response to detecting a swipe interaction from a certain point in the main display area 10 in a predetermined direction, the processor 130 may change a photographing setting value to correspond to the predetermined direction.
The processor 130 may display the live view on the main display area 10, and, in response to recognizing the live view as including a person's face, the processor 130 may control the display 110 to display the face area included in the live view on the sub display area 20.
The processor 130 may crop a part of the live view to correspond to the size of the sub display area 20 and control the display 110 to display the cropped part on the sub display area 20.
In addition, the processor 130 may display the live view on the main display area 10, and, in response to recognizing the live view as including a person, the processor 130 may control the display 110 to display an animation on the sub display area 20.
The processor 130 may determine a distance to a subject, and, in response to determining the distance is shorter than a predetermined distance, the processor 130 may control the display 110 to display the live view on the sub display area 20, and, in response to determining the distance is longer than the predetermined distance, control the display 110 to display the live view on the main display area 10.
The user terminal apparatus 100 may further include a plurality of sensors, and the processor 130 may determine whether the orientation of the user terminal apparatus 100 is changed based on at least one of a location and a motion of the user terminal apparatus 100 and a user's grip detected by the plurality of sensors.
In addition, in response to determining a person's face is greater than or equal to a predetermined size being recognized in the live view or in response to determining the person's face is greater than or equal to the predetermined size being recognized, but not recognizing the person's face afterward, the processor 130 may determine that the orientation of the user terminal apparatus 100 is changed.
FIG. 2B is a block diagram illustrating an example of a detailed configuration of a user terminal apparatus according to an embodiment of the present disclosure.
Referring to FIG. 2B, a user terminal apparatus 100 includes a display 110, a camera 120, a processor 130, a global positioning system (GPS) chip 145, a storage 140, a sensor, a communicator 150, a user interface 155, an audio processor 160, a video processor 170, a speaker 180, a button 181, and a microphone 182. The same elements of FIG. 2B as in FIG. 2A will not be described in detail.
The display 110 may be divided into the main display area 10, the sub display area 20, and the round display area 30 as described above. The display 110 may be implemented by using various types of displays such as an LCD, an OLED display, a PDP, and the like. The display 110 may further include a driving circuit which is implemented by using an amorphous silicon thin film transistor (a-si TFT), a low temperature poly silicon (LTPS) TFT, an organic TFT (OTFT), and the like, and a backlight unit. The display 110 may be combined with a touch sensor included in the sensor and may be implemented as a touch screen.
In this case, the touch sensor may include at least one of a touch panel and a pen recognition panel. The touch panel may detect a user's finger gesture input and output a touch event value corresponding to a detected touch signal. The touch panel may be mounted under at least one of the main display area 10, the sub display area 20, and the round display area 30 of the display 110.
The touch panel may detect the user's finger gesture input in a capacitive method or a resistive method. The capacitive method calculates touch coordinates by detecting minute electricity excited in a user's body. The resistive method includes two electrode plates embedded in the touch panel, and calculates touch coordinates by detecting an electric current flowing due to contact between upper and lower plates at a touched point.
The pen recognition panel may detect a user's pen gesture input according to a user's operation of using a touch pen (e.g., a stylus pen, a digitizer pen), and output a pen proximity event value or a pen touch event value. The pen recognition panel may be mounted under at least one of the main display area 10, the sub display area 20, and the round display area 30 of the display 110.
The pen recognition panel may be implemented in an electromagnetic resonance (EMR) method, for example, and may detect a touch or a proximity input according to a change in the intensity of an electromagnetic field caused by the proximity or touch of the pen. Specifically, the pen recognition panel may include an electromagnetic induction coil sensor (not shown) having a grid structure, and an electronic signal processor (not shown) which provides an alternating current (AC) signal having a predetermined frequency to each loop coil of the electromagnetic induction coil sensor in sequence. In response to a pen having a resonant circuit embedded therein existing in the proximity of the loop coil of the pen recognition panel, a magnetic field transmitted from the corresponding loop coil generates a current in the resonant circuit of the pen based on the mutual electromagnetic induction. Based on the current, an induction magnetic field is generated from the coil forming the resonant circuit in the pen, and the pen recognition panel detects the induction magnetic field from the loop coil in a signal reception state, and thus detects the proximity location or touch location of the pen.
The pen recognition panel may be configured differently according to a display area. For example, both the touch panel and the pen recognition panel may be provided in the main display area 10, and only the touch panel may be provided in the sub display area 20 and the round display area 30.
The processor 130 may deactivate a specific panel by shutting off the power to the specific panel. In addition, the processor 130 may supply power to the touch panel and the pen recognition panel and receive a touch or a pen input, but may deactivate a specific panel by disregarding an input to the specific panel in a software level.
In this case, the processor 130 may receive at least one of a hand touch and a pen touch according to whether the touch panel and the pen recognition panel of the main display area 10 are activated. For example, the processor 130 may activate only the touch panel not to receive the pen touch input and receive only the hand touch input or may activate only the pen recognition panel not to receive the hand touch input and receive only the pen touch input.
In addition, the touch panel and the pen recognition panel may be provided on the entire display area and the pen recognition panel of some areas may be deactivated. For example, the processor 130 may deactivate only the pen recognition panel corresponding to the sub display area 20 and the round display area 30.
The touch panel and the pen recognition panel may be implemented as a single panel. In this case, the processor 130 may detect a touch input and a pen input through the entire display area.
In response to the touch panel and the pen recognition panel being implemented as a single panel, the processor 130 may perform an operation corresponding to an input based on at least one of an input type and an input area. For example, the processor 130 may disregard a specific input such as a pen input in a software level. In addition, the processor 130 may disregard a pen input to the sub display area 20 in a software level.
The processor 130 may control the overall operations of the user terminal apparatus 100 using various programs stored in the storage 140.
Specifically, the processor 130 may include a random access memory (RAM) 131, a read only memory (ROM) 132, a main central processing unit (CPU) 133, a graphic processor 134, first to n-th interfaces 135-1 to 135-n, and a bus 136.
The RAM 131, the ROM 132, the main CPU 133, the graphic processor 134, and the first to n-th interfaces 135-1 to 135-n may be connected with one another via the bus 136.
The first to n-th interfaces 135-1 to 135-n may be connected with the above-described various elements. One of the interfaces may be a network interface which is connected with an external device via a network.

In response to a swipe interaction in the horizontal direction 810-1, 810-2 being detected, the processor 130 may change an exposure value and display the live view. In response to a swipe interaction in the vertical direction 820-1, 820-2 being detected, the processor 130 may display the live view while zooming in or zooming out. However, this should not be considered as limiting. The processor 130 may change a focus or change white balance through the swipe interaction.
In FIGS. 8A and 8B, only the predetermined area 11 of the main display area 10 has been described. However, this should not be considered as limiting. For example, the processor 130 may activate the touch function of the entire main display area 10, and photograph in response to a user touch on a certain point of the main display area 10 being detected. In addition, the processor 130 may divide the main display area 10 into a plurality of predetermined areas, and may allocate different functions to the predetermined areas.
The processor 130 may execute corresponding functions in response to various interactions, such as a drag and drop interaction, a multi-touch interaction, and a stretch interaction which refers to pinching out, in addition to the touch and the swipe interaction. The interactions and corresponding functions thereof may be set by the manufacturer or may be set by the user.
In FIGS. 8A and 8B, the processor 130 executes a specific function in response to a touch on the main display area 10. However, this should not be considered as limiting. For example, the processor 130 may display a live view on the main display area 10 and may not provide information on the sub display area 20. In this state, in response to a user touch on the sub display area 20 being detected, the processor 130 may photograph and store an image. In addition, in response to a swipe interaction from a certain point in the sub display area 20 in a predetermined direction being detected, the processor 130 may change the photographing setting value to correspond to the predetermined direction.
In addition, the processor 130 may display the live view on both the main display area 10 and the sub display area 20, and may use the area on the opposite side to the area which is viewed by the user as an area to receive a touch input.
In FIGS. 8A and 8B, only the case in which the camera 120 is used has been described. However, in response to another application being used, the processor 130 may receive a touch input using the area on the opposite side to the area which is viewed by the. For example, while displaying a broadcast content on the main display area 10, the processor 130 may change a channel or a volume through a swipe interaction on the sub display area 20.
In addition, in FIGS. 8A and 8B, only the main display area 10 and the sub display area 20 are used. However, one of the main display area 10 and the sub display area 20 and the round display area 30 may be used. For example, while displaying a live view on the sub display area 20, the processor 130 may photograph according to a user touch input on the round display area 30.
FIG. 9 illustrates a method of displaying a live view on both a main display area and a sub display area according to an embodiment of the present disclosure.
Referring to FIG. 9, the processor 130 may display a live view on the main display area 10, and, in response to the live view being recognized as including a person's face, the processor 130 may control the display 110 to display a face area included in the live view on the sub display area 20. For example, in response to the user terminal apparatus being far from a subject, the processor 130 may display the live view on the main display area 10. This will be explained in detail below.
The processor 130 may recognize a user's face from the live view displayed on the main display area 10. To recognize the person's face using the live view, the processor 130 may divide a specific still image of the live view into a plurality of pixel blocks, and calculates a representative pixel value from each of the pixel blocks. The representative pixel value may be calculated based on an average of all pixels included in the pixel block or may be calculated based on a maximum distribution value, a median value, or a maximum value. The processor 130 may compare the representative pixel values of the pixel blocks with one another, and determine whether pixel blocks having pixel values falling within a similar range are continuously arranged. In response to the pixel blocks being continuously arranged, the processor 130 may determine that those pixel blocks form a single object. The processor 130 may determine whether there exists an object having pixel values falling within a range similar to person's skin from among the pixel blocks determined to be the objects. In response to such an object existing, the processor 130 may recognize the object as a user's face area or other body areas, and determine the other objects as a background.
The processor 130 may crop a part 910 of the live view to correspond to the size of the sub display area 20, and control the display 110 to display the part 910 on the sub display area 20. In particular, the processor 130 may crop the part 910 of the live view while maintain the aspect ratio of the sub display area 20. The processor 130 may crop the part 910 of the live view such that the face area included in the live view is located on the center of the sub display area 20. In addition, the processor 130 may crop an area smaller than the part 910 of the live view shown in FIG. 9, and may magnify the cropped area and display the area on the sub display area 20.
In response to the live view being recognized as including people' faces, the processor 130 may display the closest person's face area to the user from among the people' faces on the sub display area 20. In addition, the processor 130 may display a face area of a person who keeps his/her eyes toward the user terminal apparatus 100 from among the people's faces on the sub display area 20. In addition, the processor 130 may crop a part of the live view to show all peoples. In response to the live view including many people, the processor 130 may display the live view on the sub display area 20 without cropping. Accordingly, the user who photographs using the user terminal apparatus 100 may identify an image to be photographed through the live view displayed on the main display area 10, and people who are photographed may identify an image to be photographed through a part of the live view which is cropped and displayed on the sub display area 20.
In FIG. 9, the operation of displaying the live view on both the main display area 10 and the sub display area 20 has been described. However, this should not be considered as limiting. For example, in response to the user terminal apparatus 100 being operated in a selfie photographing mode, the processor 130 may display the live view on the sub display area 20 and may display a UI informing that selfie photographing is in progress on the main display area 10.
FIG. 10 illustrates a method of displaying a live view on a main display area and displaying a specific content on a sub display area according to an embodiment of the present disclosure.
Referring to FIG. 10, the processor 130 may display a live view on the main display area 10, and, in response to the live view being recognized as including a person, the processor 130 may control the display 110 to display an animation on the sub display area 20. For example, in response to a child being recognized in the live view, the processor 130 may display an animation for children or an animal image on the sub display area 20. The processor 130 may output a sound corresponding to the content displayed on the sub display area 20. Accordingly, the eyes of the person who is photographed may be kept toward the user terminal apparatus 100.
The processor 130 may determine a content to be displayed on the sub display area 20 based on at least one of age and sex of a person who is recognized in the live view. For example, in response to a woman being recognized in the live view, the processor 130 may display jewelry, and the like, on the sub display area 20.
In response to people being recognized in the live view, the processor 130 may determine a content to be displayed on the sub display area 20 with reference to the closest person from among the people. In addition, the processor 130 may determine a content to be displayed on the sub display area 20 with reference to a person who keeps his/her eyes on other direction rather than toward the user terminal apparatus 100. In addition, the processor 130 may determine a content to be displayed on the sub display area 20 with reference to a person which is located closest to the center of the live view.
In FIGS. 9 and 10, the case in which a person or person's face is recognized in the live view has been described. However, this should not be considered as limiting. For example, even in response to an animal being recognized in the live view, the processor 130 may display a part of the live view, an animation, and the like, on the sub display area 20. In addition, the processor 130 may display a part of the live view, an animation, and the like, on the sub display area 20 according to user's manipulation.
FIGS. 11A and 11B illustrate an example of a method of determining an area to display a live view according to various embodiments of the present disclosure. The processor 130 may determine a distance to a subject, and, in response to the determined distance being shorter than a predetermined distance, the processor 130 may control the display 110 to display the live view on the sub display area 20, and, in response to the determined distance being longer than the predetermined distance, control the display 110 to display the live view on the main display area 10.
Referring to FIGS. 11A and 11B, a case in which a distance to a subject is shorter than the predetermined distance is illustrated in FIG. 11A, and a case in which a distance to a subject is longer than the predetermined distance is illustrated in FIG. 11B. The processor 130 may determine the distance to the subject using auto focusing. In addition, the processor 130 may analyze a still image at a specific point of time of the live view, and determine the distance to the subject based on an outline of the subject. Accordingly, in response to the user photographing himself/herself while viewing the rear surface of the user terminal apparatus 100, the live view may be displayed on the sub display area 20 so that the user may photograph while checking an image to be photographed. In addition, in response to the user photographing other people or a scene while viewing the front surface of the user terminal apparatus 100, the live view may be displayed on the main display area 10, so that the user may photograph while checking an image to be photographed.
However, this should not be considered as limiting. The processor 130 may display the live view on the opposite area to the area determined in the above-described method or may display the live view on both the main display area 10 and the sub display area 20.
In addition, the processor 130 may display the live view on an area where a user's touch is performed.
In addition, the processor 130 may determine the area to display the live view by analyzing an image photographed by the camera 120. For example, the processor 130 may recognize the user from the photographed image and determine the area to display the live view.
In addition, the processor 130 may determine the area to display the live view by recognizing user's iris.
FIG. 12 illustrates a method of detecting a change in an orientation of a user terminal apparatus according to an embodiment of the present disclosure.
Referring to FIG. 12, in response to an orientation of the user terminal apparatus 100 being changed, an image of a live view may be changed. The user terminal apparatus 100 may include a plurality of sensors as described above. The processor 130 may determine whether the orientation of the user terminal apparatus 100 is changed based on at least one of a location and a motion of the user terminal apparatus 100 and a user's grip, which are detected by the plurality of sensors. For example, the processor 130 may determine whether the orientation of the user terminal apparatus 100 is changed based on a rotation state and a moving direction of the user terminal apparatus 100 detected by the geomagnetic sensor, and a rotation angle of the user terminal apparatus 100 detected by the gyro sensor.
In response to the user terminal apparatus 100 being rotated in a specific direction by more than a predetermined angle, the processor 130 may determine that the orientation of the user terminal apparatus 100 is changed. For example, in response to the user terminal apparatus 100 being rotated by more than 90°, the processor 130 may determine that the orientation of the user terminal apparatus 100 is changed and perform a corresponding operation.
In response to a person's face being greater than or equal to a predetermined size being recognized in the live view or in response to the person's face being greater than or equal to the predetermined size being recognized, but the person's face not being recognized afterward, the processor 130 may determine that the orientation of the user terminal apparatus 100 is changed. FIG. 12 illustrates a plurality of still images of a live view in sequence. The first still image 1210 is an image without a person and the second to fourth still images 1220, 1230 and 1240 are images with a person. The fifth image 1250 is an image without a person. That is, FIG. 12 illustrates that a camera angle is moved from the left to the right and then is moved back to the left.
The processor 130 may determine that the orientation of the user terminal apparatus 100 is changed at the time at which the second still image 1220 is displayed and at the time at which the fifth still image 1250 is displayed as shown in FIG. 12.
However, this should not be considered as limiting. The processor 130 may determine whether the orientation of the user terminal apparatus 100 is changed with reference to other objects rather than the person's face. For example, the processor 130 may extract an outline of a slide from a specific still image of the live view and then extract the outline of the slide from the next still image, and, in response to the outline of the slide being recognized as being moved by more than a predetermined distance on the live view, the processor 130 may determine that the orientation of the user terminal apparatus 100 is changed.
In addition, the processor 130 may continue detecting an absolute posture using various sensors provided in the user terminal apparatus 100, and determine whether the orientation of the user terminal apparatus 100 is changed.
In this case, the processor 130 may set a reference posture, and, in response to the posture being changed from the reference posture by more than a predetermined value, the processor 130 may determine that the orientation of the user terminal apparatus 100 is changed. Herein, the reference posture is a posture when a camera application is selected.
In addition, the processor 130 may determine whether the orientation of the user terminal apparatus 100 is changed according to user's touch manipulation.
FIGS. 13A and 13B illustrate an example of an operation according to the change of an orientation of a user terminal apparatus according to various embodiments of the present disclosure.
Referring to FIG. 13A, in response to an orientation of the user terminal apparatus 100 being changed while a photographing function is being executed, a gallery application is executed.
