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 or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. 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, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected through the proximity sensor 141 as described above, and further, provides visual information corresponding to the processed data.

The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, 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 then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and the right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail refers to a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated as described above are displayed with a left and right distance difference on the screen by a depth corresponding to the parallax of the left image and the right image, thereby representing a three-dimensional space.

The left image and the right image necessary for implementing the 3D stereoscopic image may be displayed on the stereoscopic display by the stereoscopic processing unit.

In detail, when the direction information 220 set to output one side (one edge) of the image 210 toward one direction (upward direction) is linked to the image 210, the controller 180 controls the direction. Based on the information 220, the image 210 may be output such that one side of the image 210 faces the one direction.

If, as shown in (c) of FIG. 2A, the image 210 is output in a state in which the main body 100 is upright (in a horizontal mode) such that the width direction of the front surface of the main body 100 corresponds to the gravity direction. In this case, the controller 180 outputs the image 210 such that one side of the image 210 faces one direction (up direction) based on the direction information 220 linked to the image 210. can do. In this case, the image 210 may be output such that one side of the image 210 faces the left side (or the right side) of the display unit 151.

If, as shown in (d) of FIG. 2A, the image 210 is output in the state in which the main body 100 is upright (in the vertical mode) such that the longitudinal direction of the front surface of the main body 100 corresponds to the gravity direction. The controller 180 controls the image 210 such that one side of the image 210 faces one direction (up direction) based on the direction information 220 linked to the image 210. You can print In this case, the image 210 may be output such that one side of the image 210 faces the upper side (or the lower side) of the display unit 151.

Through this configuration, in the present invention, even when the posture of the main body is changed, the size of the output image is changed, and the direction of the image output based on the user based on the direction information linked to the output image. It is possible to provide a user interface capable of outputting the image to be constant.

On the other hand, the direction information (first direction information), if the posture of the main body 100 when shooting the image satisfies a predetermined condition, the side that the user does not want among the plurality of surfaces (side, edge) of the image It can be set (determined) in the upward direction.

The preset condition is a state in which the main body 100 is inclined at a predetermined inclination as shown in (a) of FIG. 2B, or the main body 100 is laid down as shown in (b) of FIG. 2B. This may be the case when an image is taken.

Specifically, as shown in (a) of FIG. 2B, when photographing the preview image, the virtual body 100 is erected (that is, an imaginary line vertically penetrating the front surface of the main body 100 in this gravity direction g). Perpendicular to the imaginary line), and an imaginary line corresponding to the longitudinal direction of the front surface of the main body 100 based on the imaginary line corresponding to the gravity direction g (for example, about 45 degrees). When the photographing operation is performed in a tilted state, the preset condition may be satisfied.

As another example, as shown in (b) of FIG. 2B, when photographing the preview image, an imaginary line vertically penetrating the front surface of the main body 100 when the main body 100 is laid down (that is, the gravity direction ( When the photographing operation is performed in a state corresponding to (or in parallel with) the virtual line corresponding to g), the preset condition may be satisfied.

In this case, as illustrated in (a) of FIG. 2C, the image 210 photographed in a state that satisfies a predetermined condition may have a side (for example, an upper side) different from one side of the image (eg, an upper side). For example, the direction information 222 may be linked such that the left side faces upward.

In this case, the controller 180 outputs the image 210 to the display unit 151 based on the direction information 222 linked to the output image 210.

For example, as shown in (b) of FIG. 2C, when the main body 100 is placed in the portrait mode, the image 210 may have a different side (eg, a left side) of the image 210. It may be output to the display unit 151 to face upward. In this case, the upper side of the image 210 may be output to face the right side (or the left side) of the display unit 151.

As another example, as shown in (c) of FIG. 2C, when the main body 100 is set up in a landscape mode, the image 210 may have a different side (eg, a left side) of the image 210. It may be output to the display unit 151 to face upward. In this case, the upper side of the image 210 may be output to face the upper side (or the lower side) of the display unit 151.

In this case, the image is rotated and output based on the user on the display unit 151. In order to view this image directly on a user basis, it is inconvenient to rotate the image through a separate operation or to rotate the main body itself while the image is set not to rotate.

The present invention can provide an optimized image output method that can solve the above inconvenience. Hereinafter, when the image is taken, the direction information associated with the captured image will be referred to as 'first direction information'.

3 is a flowchart representatively showing a control method of the present invention, and FIG. 4 is a conceptual diagram for explaining the control method described with reference to FIG. 3.

In the present invention capable of eliminating the above inconvenience, first, an image is output based on first direction information linked to the image (S310).

In detail, when there is an output request for a previously photographed or pre-stored image, the controller 180 displays the image based on the first direction information linked to the image having the output request. Can be output to

For example, as shown in FIG. 4, when the direction information 310 associated with the output request image 300 is set such that the left side of the image 300 faces upward, the controller 180 Based on the direction information 310, the image may be output such that the left side of the image 300 faces upward.

Then, in the present invention, the step of determining the second direction information through the output image analysis proceeds (S320).

In detail, the controller 180 may analyze the output request image 300. An algorithm for performing the analysis of the image 300 may use various algorithms disclosed in the related art. For example, the various algorithms may include a face recognition algorithm, an object recognition algorithm, and the like. Since the algorithm itself for performing the image analysis is outside the gist of the present invention, a detailed description thereof will be omitted.

The controller 180 may determine the second direction information by analyzing the image 300 output (or output requested) to the display unit 151. For example, the controller 180 may perform image analysis to determine in which direction the output image 300 should be output. The determination (or the image analysis) may be performed based on a preset algorithm.

The preset algorithm may be an algorithm for determining a state in which screen information included in an image (for example, an image corresponding to a subject) is not rotated based on a user (or based on a gravity direction). Specifically, the preset algorithm is programmed (or set) by the user, and the screen information included in the direction (or the screen information included in the image) should be output based on the user (or based on the gravity direction). Direction) may be a predetermined algorithm.

For example, according to the preset algorithm, when an image corresponding to a horizontal line (or a horizon) is included in the image, the controller 180 is configured to output an image corresponding to the horizontal line included in the image to be perpendicular to the gravity direction. 2 direction information can be set.

As another example, according to the preset algorithm, when the image of the person is included in the image, the controller 180 is a virtual line of the person image (for example, a virtual line through the forehead, nose, mouth) corresponds to the direction of gravity The second direction information may be set to correspond to (parallel) the virtual line. However, the present disclosure is not limited thereto, and the preset algorithm may be set in various ways.

In addition, the controller 180 may determine the second direction information based on not only an image analysis result but also information detected by the sensor 140 at the time of capturing.

The second direction information may be information related to a direction set so that the image output direction satisfies a preset algorithm based on the user (or based on the gravity direction). That is, the second direction information may be direction information that is set so that the image is output straight without rotating from the user's point of view.

In other words, the controller 180 may output one side (eg, a direction opposite to the gravity direction) of a plurality of side surfaces (edges and edges) of the image through image analysis (or a predetermined algorithm). For example, the upper side) can be determined. That is, the second direction information may be information obtained by determining one side of an image to be output in an upward direction so as to satisfy a preset algorithm.

For example, as illustrated in FIG. 4B, the controller 180 may analyze the output image 300 and determine the second direction information 320 based on the image analysis result. have. That is, as shown in (b) of FIG. 4, the second direction information 320 rotates an image corresponding to a subject included in the image 300 based on the gravity direction (or the user). It may be direction information for outputting in a non-state state.

Then, in the present invention, the step of determining whether to rotate the output image based on the first direction information associated with the output image and the second direction information determined through image analysis (S330). In detail, the controller 180 may determine whether to rotate the output image 300 based on the first direction information 310 and the second direction information 320.

Then, in the present invention, the step of outputting the image 300 based on the determination proceeds (S340).

In detail, the controller 180 may maintain the output of the image 300 when the first direction information 310 and the second direction information 320 correspond to each other. In contrast, as shown in FIG. 4C, when the first direction information 310 and the second direction information 320 do not correspond to each other, the controller 180 displays the second direction information 320. ) May rotate the output image (300).

Here, the correspondence between the first direction information 310 and the second direction information 320 means that one side of an image set to be output upward by first direction information is upward by second direction information. This may mean the same as one side of the image set to be output in the direction.

In this case, the fact that the first direction information 310 and the second direction information 320 do not correspond is that one side of the image set to be output upward by the first direction information is the second direction information. This may mean that the image is different from one side of the image set to be output upward.

Subsequently, when the output image 300 is rotated, the controller 180 can change the first direction information 310 linked to the image 300 to the second direction information 320. That is, when the output image 300 is rotated, the controller 180 may change the first direction information 310 linked to the image 300 to the second direction information 320 and associate the same. . Subsequently, when the image 300 is output to the display unit 151 again according to a user's request, the controller 180 controls the image based on the second direction information 320 linked to the image 300. 300 may be output to the display unit 151.

Meanwhile, in the present invention, steps S320 to S340 may be performed in a state in which an image is not output. In detail, when there is an output request for an image, the controller 180 may determine the second direction information by analyzing the output request image while not outputting the output request image. Thereafter, the controller 180 may determine whether to rotate and output the output requested image based on the first direction information and the second direction information associated with the output requested image. Thereafter, the controller 180 can output the output request image to the display unit 151 based on the determination (or based on the second direction information).

Through such a configuration, the present invention provides a user interface and a control method capable of properly outputting the image from the user's point of view without an additional operation when the image is output in a direction that the user does not want by the direction information set at the time of shooting. can do.

Hereinafter, for convenience of description, it will be described that the direction information (first and second direction information) is set on one side of the image. The direction information (first and second direction information) is information indicating an upward direction, and the fact that the direction information is set on one side of the image indicates that one side of the image is directed upward when the image is output. It may mean that it is set to. For example, when the direction information is set on the first side, the controller 180 outputs an image such that the first side faces upward, and when the direction information is set on a second side different from the first side, The image may be output so that the second side faces upward.

Hereinafter, a method of outputting an image based on the first and second direction information will be described in more detail with reference to the accompanying drawings.

5A, 5B, and 5C are conceptual views illustrating a method of rotating an image according to an exemplary embodiment.

First, the controller 180 may determine whether to rotate the image based on the first direction information previously stored (pre-associated) and the second direction information determined through image analysis.

In this case, the degree to which the image is rotated may be determined based on the first direction information and the second direction information. For example, when the first direction information is set on the first side of the image, and the second direction information is set on the second side perpendicular to the first side, the controller 180 displays the image. Can also be rotated.

On the other hand, when the first direction information is set on the first side of the image and the second direction information is set on the third side opposite to the first side, the controller 180 rotates the image 180 degrees. You can.

In this case, the image may be rotated in a preset direction regardless of the degree to which the image is rotated. For example, when the first direction information and the second direction information set in the image do not correspond to each other, the controller 180 may rotate the image based on the first and second direction information. In this case, the controller 180 may determine the degree to which the image is rotated based on the first and second direction information. In addition, the controller 180 may rotate the image in a predetermined direction regardless of the degree to which the image is rotated.

Referring to FIG. 5A, the preset direction may be a clockwise direction, for example. Sides of the image described below will be described based on the first direction information. That is, the side where the first direction information is set among the plurality of side surfaces of the image may be an upper side. This is because the controller 180 outputs an image such that the side at which the first direction information is set faces upward when initially outputting.

More specifically, referring to FIG. 5B, as shown in (a) of FIG. 5B, through image analysis of the first direction information 510 and the image 500 linked to the output image 500. When the determined second direction information 520 corresponds (that is, when the first and second direction information are set on one side of the image), the controller 180 may not rotate the output image 500. Can be.

Meanwhile, as illustrated in (b) of FIG. 5B, the first direction information 510 is set on the first side (eg, the upper side) of the image 500, and the second direction information 520 is the above. When set to a second side surface (eg, left side) that is perpendicular to the first side surface and exists on the left side, the controller 180 may view the image 500 in a preset direction (eg, clockwise direction) 90. Can also be rotated.

Meanwhile, as illustrated in (a) of FIG. 5C, the first direction information 510 is set on the first side (eg, the upper side) of the image 500, and the second direction information 520 is the above. When set to the third side surface (eg, the lower side) opposite to the first side surface, the controller 180 may rotate the image 500 by 180 degrees in a preset direction (eg, clockwise direction). have.

In addition, as illustrated in (b) of FIG. 5C, the first direction information 510 is set on the first side (eg, the upper side) of the image 500, and the second direction information 520 is the above. When set to a fourth side (eg, right side) that is perpendicular to the first side and is present on the right side, the controller 180 may rotate 270 degrees in a preset direction (eg, clockwise direction).

That is, the degree to which the image 500 is rotated may be determined by determining the first direction information 510 and the second direction information 520, and the direction in which the image is rotated may correspond to the degree to which the image is rotated. Regardless, it may be rotated in a predetermined direction.

The controller 180 may rotate the image in different directions based on the first direction information and the second direction information.

For example, as shown in FIG. 5B (b), when the second direction information 520 is located on the left side based on the first direction information 510 (that is, the first direction), When the second direction information is set on the second side that is perpendicular to the first side on which the direction information is set, the image 500 may be rotated in the first direction (eg, clockwise direction).

As another example, as shown in (b) of FIG. 5C, when the second direction information 520 is located on the right side based on the first direction information 510 (that is, the first direction), When the second direction information is set on the fourth side that is perpendicular to the first side where the information is set and the right side), the controller 180 is opposite to the first direction, as shown in (b) of FIG. 5C. The image may be rotated in a second direction (for example, counterclockwise). In this case, the image 500 may be rotated 90 degrees in a second direction (counterclockwise direction).

On the other hand, as shown in (a) of FIG. 5C, when the second direction information 520 is located opposite to the first direction information 510 (that is, the first side information is opposite to the first side where the first direction information is set). When the second direction information is set on the third side surface, the controller 180 may rotate the image 500 in a first direction (clockwise) or in a second direction (counterclockwise). In this case, the direction in which the image is rotated may be determined based on a user setting or under the control of a controller.

On the other hand, as shown in (b) to 5c (b) of Figure 5b, when the first direction information 510 and the second direction information 520 set in the image 500 does not correspond, the controller ( 180 may output the first graphic object corresponding to the first direction information 510 and the second graphic object corresponding to the second direction information 510 to the display unit 151.

The first and second graphic objects may be output to the display unit 151 together with the image 500.

Thereafter, the controller 180 may rotate the image 500 based on a preset type of touch applied to one of the first and second graphic objects.

The preset type of touch is a touch of various methods associated with a function of rotating an image, and includes a short (or tap) touch, a continuous touch and a long touch in which at least two short touches are applied within a reference time. long touch, multi touch, drag touch, flick touch, pinch-in touch, pinch-out touch, swipe It may include various types of touch, such as a swype touch, a hovering touch, and the like.

For example, when a preset touch (for example, a drag touch) is applied to the first graphic object corresponding to the first direction information, the controller 180 may display an image based on the preset touch. Can be rotated. In this case, the output position of the first graphic object may be changed based on the touch of the preset method. That is, the change of the output position of the first graphic object may mean that the side (position) of which the first direction information is set in the image is changed.

When a preset type of touch is applied to the first graphic object, the image output to the display unit 151 may be rotated (outputted) based on the first direction information changed by the preset type of touch. In this case, when the changed first direction information and second direction information correspond to the preset type of touch, the controller 180 may cause the first and second graphic objects to disappear.

For example, referring to (a) of FIG. 5C, a drag touch starting from a first graphic object corresponding to the first direction information 510 corresponds to the second direction information 520. When released from the object, the controller 180 can rotate the image 500 based on the drag touch. The output position of the first graphic object may be around the second graphic object corresponding to the second direction information 520 (or a point where the drag touch is released). In this case, the first direction information 510 is changed to a side surface (for example, a third side surface) on which the second direction information 520 is set.

Thereafter, the controller 180 may make the first and second graphic objects disappear based on the correspondence of the changed first direction information and second direction information 520.

On the other hand, the controller 180 maintains the output of the first and second graphic objects when the changed first direction information and the second direction information do not correspond to each other based on the touch of the preset method, and changes the changed direction information. The notification information for requesting confirmation of correctness may be output to the display unit 151.

Referring to (b) of FIG. 5C, the first direction information 510 is set on the first side (upper side) of the image 500, and the second direction information 520 is formed on the first side of the image 500. 4, when the drag touch starting from the first graphic object corresponding to the first direction information 510 is released at a portion adjacent to the second side (left side) of the image, the controller 180 is set to the side (right side). Based on the drag touch, the image 500 may be rotated as shown in the first drawing of FIG. 5C (a). Thereafter, the controller 180 maintains the output of the first and second graphic objects based on the fact that the first direction information and the second direction information changed based on the drag touch do not correspond, and the changed direction information is changed. Notification information requesting confirmation of fit may be output to the display unit 151.

As another example, when a touch of a preset method is applied to the second graphic object corresponding to the second direction information, the controller 180 may rotate the image based on the touch of the preset method. At this time, the output position of the second graphic object may be changed based on the touch of the preset method.

For example, starting from the second graphic object corresponding to the second direction information 520 set on the third side (lower side) of the image 500, as shown in the first drawing of FIG. 5C (a). When the drag touch is released at a portion adjacent to the first side surface (upper side) of the image 500 in which the first graphic object corresponding to the first direction information 510 is displayed, the controller 180 based on the drag touch, As shown in FIG. 5A, the image 500 may be rotated.

 The output position of the second graphic object may be around the first graphic object corresponding to the first direction information 510 (or a point where the drag touch is released). In this case, the second direction information 520 is changed to the side surface (for example, the first side surface) on which the first direction information 510 is set.

Thereafter, the controller 180 may make the first and second graphic objects disappear based on the correspondence between the first direction information and the changed second direction information 520.

On the other hand, the controller 180 maintains the output of the first and second graphic objects when the changed first direction information and the second direction information do not correspond to each other based on the touch of the preset method, and changes the changed direction information. The notification information for requesting confirmation of correctness may be output to the display unit 151.

Through such a configuration, the present invention can provide a user interface capable of rotating and outputting an image in an optimized manner.

The above description may be similarly applied similarly even when the video is a video.

Specifically, when the output requested image is a video, the first direction information determined based on the posture of the main body at the time of capturing may be linked to the video.

The display unit 151 may play a video based on the first direction information associated with the video.

The controller 180 may perform image analysis on the output video (that is, the video being played). In detail, the controller 180 may determine the second direction information by performing image analysis on a still image corresponding to at least a portion (or at least some viewpoints) of the playing time of the video. In this case, the second direction information determined through image analysis of the image (still image) of the corresponding viewpoint may be linked to at least a part of the playing time of the video.

For example, when at least a part of the playing time of the video is t_1 and t_2, the controller 180 may perform a first analysis at each time point through screen analysis on still images of t_1 and t_2 time points of the playing time of the video. Two direction information can be determined.

At least a part of the video playing time may be determined based on a user setting, or a sudden screen change (for example, when a color value of an image before t_1 and an image after t_2 changes to an average value or more) is performed. It may be a time point.

Thereafter, the controller 180 may determine whether to rotate the playing video based on the first direction information and the second direction information determined through image analysis.

For example, if the playback point of the video reaches a time point at which the first direction information and the second direction information do not correspond while the video is being played back according to the passage of time, the controller 180 is connected to the second direction information. Based on this, the video being played can be rotated.

For example, when the second direction information at the time t_1 corresponds to the first direction information in the video playback time, the controller 180 is playing the video even when the time at the video playback time reaches the time t_1 according to the passage of time. You can not rotate the video.

On the other hand, when the second direction information at the time t_2 does not correspond to the first direction information during the playback time of the video, when the playback time of the video reaches the time t_2 as the time passes, the video being played is It may be rotated based on the second direction information.

When the video being played is rotated, the controller 180 can change and store the second direction information set at the time when the video is rotated as the first direction information.

Through such a configuration, the present invention can provide a user interface that can be reproduced in an optimized manner even when a video is being reproduced without rotating the image through a separate operation.

The above description will be made clear with reference to FIG. 6.

6 is a flowchart illustrating a method of outputting an image according to an exemplary embodiment.

First, the controller 180 of the present invention may analyze the output request (or output) image (S610). The image analysis may be performed while the image is output to the display unit 151 or may be performed while the image is not output to the display unit 151.

Thereafter, the controller 180 may determine an output direction (ie, second direction information) of the image based on the image analysis result (S620).

Thereafter, the controller 180 may compare the direction information (ie, first direction information associated when the image is photographed) associated with the image with the determined output direction (S630 and S640).

Subsequently, when the associated direction information (first direction information) and the determined output direction (second direction information) correspond (match), the controller 180 may output an image based on the first direction information. Can be (S650).

On the other hand, if the associated direction information (first direction information) and the determined output direction (second direction information) do not correspond (not matched), the controller 180 can rotate the image according to the determined output direction. There is (S660). The controller 180 may output the rotated image to the display unit 151.

When the image is output to the display unit 151 (that is, when the image is already output to the display unit 151 based on the first direction information), the controller 180 may determine the determined output direction (second Direction information) to rotate the output image.

In contrast, when the image is not output to the display unit 1510, the controller 180 may output the rotated image to the display unit 151 based on the determined output direction (second direction information).

Thereafter, the controller 180 may store the determined output direction (second direction information) in the image (S670).

Meanwhile, in the present invention, direction information may be stored in association with an image photographed by various methods during image capturing. 7 is a flowchart illustrating a method of associating direction information with an image according to an exemplary embodiment.

As described above, the mobile terminal 100 of the present invention detects a posture of the main body 100 including the display unit 151, the camera 121 provided in the main body 100, and the main body 100. It may include a sensing unit 140.

The controller 180 determines the first direction information based on the posture of the main body 100 when capturing the image received through the camera 121, and captures the determined first direction information. Can be linked to

On the other hand, if the posture of the main body at the time of capturing the image satisfies a preset condition, the controller 180 links the determined direction information to the photographed image instead of the first direction information. You can.

For example, the preset condition is that, as described in (a) of FIG. 2B, the posture of the main body 100 at the time of photographing corresponds to the longitudinal direction of the front surface of the main body 100 based on the gravity direction g. The image may be taken when the virtual line is inclined within a predetermined angle range (for example, about 45 degrees) based on the virtual line corresponding to the gravity direction g.

As another example, the preset condition is a state in which the posture of the main body 100 is laid down, that is, the virtual line vertically penetrating the front surface of the main body at the time of photographing, as described in (b) of FIG. 2B. May be parallel to (or correspond to) an imaginary line. However, the case where the imaginary line penetrating the front of the main body vertically and the imaginary line corresponding to the gravitational direction (g) is inclined by a predetermined angle range (for example, about 10 degrees) may be included in the preset condition. Do.

In this case, the controller 180 analyzes the captured image to determine direction information (output direction, second direction information), and captures the determined direction information instead of the first direction information determined based on the attitude of the main body. Can be stored in conjunction with In this case, when there is a request for outputting the captured image, the controller 180 may output the captured image based on the direction information (for example, output direction and second direction information) associated with the image. Can be.

As another example, the preset condition may be related to a sensor value.

Referring to FIG. 7, when the image is captured, the controller 180 checks the sensor value measured by the gyro sensor or the acceleration sensor included in the detector 140 (S710).

Thereafter, the controller 180 determines whether the sensor value has high reliability, that is, whether the sensor value is within a preset value (or range) (for example, whether the acceleration value is around 0 (m / (s ^ 2)). It may be determined whether or not it corresponds (S720).

High reliability of the sensor value may mean that the preset condition is not satisfied. On the other hand, low reliability of the sensor value may mean that the preset condition is satisfied.

When the reliability of the sensor value is high, the controller 180 determines the output direction of the captured image based on the sensor value (ie, determines the first direction information based on the attitude of the main body) (S730). .

On the other hand, when the reliability of the sensor value is low, the controller 180 analyzes the photographed image to determine the photographing direction (that is, performs the photographed image analysis to determine the second direction information) (S740).

For example, the controller 180 detects a movement of the main body 100 before a predetermined time from the photographing time point through the gyro sensor or the acceleration sensor of the sensing unit 140, and the sensor value measured by the movement. If it is out of this preset value (or range) (i.e., when the main body shakes within the reference time more than the reference amplitude or moves the reference distance within the reference time immediately before shooting), the controller 180 controls the reliability of the sensor value. May be determined to be low and analyze the photographed image to associate the determined direction information (the photographing direction and the output direction) with the photographed image.

As another example, the controller 180 detects a movement of the main body 100 before a predetermined time from the photographing time point through the gyro sensor or the acceleration sensor of the sensing unit 140, and the sensor value measured by the movement is When the value is within a preset value (or range) (ie, when the main body is almost not shaken or moved just before shooting), the controller 180 determines that the reliability of the sensor value is high, and is determined based on the posture of the main body when shooting. The first direction information may be linked to the captured image.

Through such a configuration, the present invention can provide a control method that can more accurately set the direction in which the image is output.

As described above, according to the present invention, the present invention determines whether to rotate the output image based on the first direction information associated with the image and the second direction information determined by analyzing the image, and based on the determination The video can be output. Accordingly, the present invention can provide a user interface that allows a user to watch an image in an optimized manner.

The present invention described above can be embodied as computer readable codes on a medium in 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 computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like. This also includes implementations in the form of carrier waves (eg, transmission over the Internet). In addition, the computer may include the controller 180 of the terminal. Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
