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

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen. The proximity sensor 141 has a longer life span than the contact-type sensor, and its utilization is also high.

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

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

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, etc. of a touch object to be touched on the touch screen on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

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

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

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

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

The camera 121 includes at least one of a camera 121, a photosensor, and a laser sensor. The camera 121 is a kind of camera sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

In addition, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit by the stereoscopic processing unit. The stereoscopic processing unit receives a 3D image (an image at a reference time point and an image at an expansion point), sets a left image and a right image therefrom, or receives a 2D image and converts it into a left image and a right image.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings.

FIG. 3A is a conceptual diagram illustrating a principle of projecting an image on a screen of a mobile terminal according to an embodiment of the present invention. FIG. FIG. 7 is a conceptual diagram illustrating an image displayed on the display unit when there are a plurality of screens described.

2, a mobile terminal according to an embodiment of the present invention includes a main body, a sensing unit 140, a display unit 151, a reflection plate 210, a screen 220, and a control unit 180. Hereinafter, the constituent elements will be described in detail.

The sensing unit 140 senses the movement of the main body. The sensing unit 140 includes a proximity sensor 141, an illuminance sensor 142, an acceleration sensor, a magnetic sensor, a gravity sensor, a gyroscope sensor, a motion sensor, and the like.

For example, the sensing unit 140 may sense the rotation of the main body with respect to the virtual axis, and may sense movement of the main body moving along a predetermined direction.

The display unit 151 is provided on the front surface of the main body and outputs an image so that an image is projected on the screen 220. The image output to the display unit 151 is reflected by the reflection plate 210.

The reflection plate 210 may be formed parallel to the display unit 151 and reflects the image output to the display unit 151. The image reflected from the reflection plate 210 is projected on the screen.

The screen 220 projects an image reflected from the reflection plate 210. That is, the image outputted to the display unit 151 is projected onto the screen 220 through the reflection plate 210.

3, the reflection plate 210 reflects an image output to at least a partial area of the display unit 151. As shown in FIG. The screen 220 projects the image reflected by the reflection plate 210. When the screen 220 is transparent, the user experiences an experience of seeing an image output in the air through the image projected on the screen 220. At this time, when there is a shield between the display unit 151, the reflection plate 210, and the screen 220, the image output to the display unit 151 can not be perfectly projected on the screen 220.

Therefore, while the image is being projected on the screen 220, the display unit (touch screen) is hardly utilized as the input means. The control unit 180 may restrict the control of the touch input applied to the display unit 151 while the image is projected on the screen 220 so that the image is perfectly projected on the screen 220. [

On the other hand, the screen 220 may be one or more. For example, if the number of screens 220 is one, the user can view the image projected on the screen 220 only in one direction. In another example, if the number of screens 220 is four, the user can view different images projected on the plurality of screens 220 according to the direction in which the screen 220 is viewed.

When there are a plurality of screens 220, a plurality of images to be projected on each of the plurality of screens 220 is required. In order to output a plurality of images, the present invention can form a plurality of areas on one display unit 151. [ The same image may be outputted to each of the areas, or different images may be output.

For example, as shown in FIG. 3B, when there are four screens 220, the controller 180 divides the display unit 151 into four areas, and then displays a front view, a left side view, The right side view, and each of the output images may be projected on a different screen 220. [0034] FIG. At this time, the user can see the front face, the left face, the rear face, and the right face of the specific object according to the direction in which the screen 220 is viewed.

On the other hand, when all the images output to the areas are the same, the user sees the same image in four directions regardless of the direction in which the screen 220 is viewed.

As described above, the mobile terminal according to the present invention provides the user with the image projected on the screen 220. As described above, in a state in which an image is projected on the screen 220, the display unit 151 is limited in use as an input means, and an input means for controlling an image projected on the screen 220 is required.

Hereinafter, a method of outputting an image projected on a screen of a mobile terminal according to the movement of the main body according to the present invention will be described in detail.

FIG. 4 is a flowchart illustrating a method of changing an image projected on a screen of a mobile terminal according to movement of a main body according to an embodiment of the present invention. FIGS. 5A and 5B are views In accordance with the movement of the main body.

First, an image is output to at least a part of the display unit 151 so that the first image is projected on the screen 220 (S410). The first image may be a two-dimensional image, a three-dimensional image, and a moving image. The image projected on the screen 220 may vary depending on the image output to the display unit 151. The control unit 180 controls the display unit 151 so that the image can be projected on the screen 220.

Next, when the motion of the main body of the terminal is detected, the first image projected on the screen 220 is changed to the second image according to the movement of the terminal, (S420).

The sensing unit 140 senses the movement of the terminal body. Here, the movement of the main body may be a movement rotating at a predetermined angle with respect to a virtual axis, or may be a movement of the main body moving along one direction.

As shown in FIG. 5A, when the movement of the main body is a movement of rotating at a predetermined angle with respect to a virtual axis, the controller 180 may change the second image according to the predetermined angle. Specifically, in a state in which a front view of an object is projected on the screen 220, the control unit 180 selects either the right side view, the left side view, or the rear view of the object based on the predetermined angle, The display unit 151 may be controlled so that the second image is projected on the screen 220. [

As shown in FIG. 5A, when the main body of the controller 180 rotates to the right, the right side view can be projected on the screen. On the other hand, although not shown in the drawings, when the main body rotates to the left, the left side view may be projected on the screen.

In addition, the control unit 180 may change the image projected on the screen 220 when the predetermined angle exceeds the reference angle regardless of the predetermined angle.

On the other hand, the imaginary axis may be one or more. When there are a plurality of virtual axes, the controller 180 may change the second image according to the type of the axis that is the reference of rotation of the main body. Specifically, when the movement of the main body is a movement in which the movement of the main body is rotated at a predetermined angle with respect to any one of the imaginary first and second axes, The display unit 151 can be controlled so that the image is projected.

5B, when the main body moves in one direction, the controller 180 may change the second image according to the moving distance of the main body. Specifically, when enlarging or reducing the first image as the main body moves in one direction, the controller 180 calculates the enlarged or reduced ratio according to the moving distance, and if the second image is enlarged or reduced according to the calculated ratio, The display unit 151 can be controlled so that the image is projected.

For example, when the main body moves in the direction shown in FIG. 5B, the control unit 180 controls the display unit so that the enlarged image of the first image is projected on the screen, and controls the display unit in a direction opposite to the direction shown in FIG. The controller may control the display unit such that the reduced image of the first image is projected on the screen.

On the other hand, the one direction may be one or more. The controller 180 may change the second image according to the type of the one direction. Specifically, the controller 180 may change the second image according to the direction in which the main body moves regardless of the moving distance of the main body.

As described above, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention provides a method of changing an image output to a screen according to motion of a main body. Thus, the user can control the image projected on the screen without applying the touch input while the image is projected on the screen.

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

6A to 6C are conceptual diagrams showing a state in which the image projected on the screen described in FIG. 3 is changed according to the movement of the main body.

An image corresponding to a partial area of a predetermined image may be projected on the screen. Only a portion of the image included in the region is projected on the screen 220. [ The control unit 180 may reset the area on the image according to the movement of the main body and may control the display unit 151 so that the image corresponding to the reset area is projected on the screen 220. [

6A, when the main body rotates to the right by a predetermined angle with respect to the imaginary axis in a state that the first image corresponding to the first area 610 of the predetermined image is projected on the screen 220, The control unit 180 controls the display unit 151 to change the first area 610 to the second area 620 according to the angle and to project the second image corresponding to the second area 620, do. 6A, the second area 620 has the same size as the first area 610, but the position on the predetermined image is different. As the main body rotates to the right, the position of the area also shifts to the right.

That is, the user can see the right portion of the predetermined image by rotating the main body to the right by a predetermined angle. On the other hand, although not shown in the figure, when the main body rotates to the left by a predetermined angle, the left part of the predetermined image may be output.

6B, when the first image corresponding to the third region 630 of the predetermined image is projected on the screen 220 and the main body moves along one direction, the controller 180 Changes the third region 630 to the fourth region 640 according to the moving distance of the main body. At this time, the fourth region 640 has the same center point as the third region 630, but has a different size. That is, the user can move the main body along the direction shown in FIG. 6B, thereby reducing a portion of a predetermined image.

Meanwhile, although not shown in the drawing, when the main body moves along the direction opposite to the direction shown in FIG. 6B, an enlarged image of a part of the predetermined image can be projected on the screen.

On the other hand, the image projected on the screen 220 may be an image of a region corresponding to a reference position, a predetermined direction, and a predetermined viewing angle. The control unit 180 may change at least one of the reference position, the predetermined direction, and the predetermined viewing angle according to the movement of the main body, and may change an image projected on the screen 220 according to the reference position, the predetermined direction, . In other words, the user can see various areas in various visibility by moving the main body.

For example, as shown in FIG. 6C, when the main body rotates at a predetermined angle with respect to a virtual axis in a state where an image of an area corresponding to the first direction is projected on the screen 220, And changes the first direction to the second direction according to the angle. At this time, the second direction is to the right of the first direction. The control unit 180 controls the display unit 151 to project an image of an area corresponding to the second direction onto the screen 220. [ That is, by rotating the main body, the user can move the field of view looking to an area to the right.

On the other hand, a moving picture including a plurality of reproduction points may be reproduced on the screen 220. [

7A and 7B are conceptual diagrams showing a moving image outputted to a screen changing according to the movement of the main body.

The first image may be an image corresponding to a first reproduction point of a moving image including a plurality of reproduction points. At this time, the control unit 180 controls the display unit 151 to project the second image corresponding to the second reproduction time point instead of the first image corresponding to the first reproduction time point based on the first movement of the main body, The display unit 151 may be controlled so that the second image, in which the first image is enlarged or reduced, is projected based on the first movement and the second movement of the other body.

The control unit 180 may control the display unit 151 to project different images on the screen 220 according to the type of movement of the main body. Specifically, the first movement may be a movement in which the main body rotates at a predetermined angle with respect to the imaginary first axis, and the second movement is performed at a predetermined angle with respect to the second virtual axis different from the first axis It can be a rotating movement.

When the main body rotates at a predetermined angle with respect to the first axis, the controller 180 controls the second image corresponding to the second reproduction time, instead of the first image corresponding to the first reproduction time, So that the display unit 151 can be controlled. At this time, the second reproduction time may be changed based on the predetermined angle.

For example, as shown in FIG. 7A, when the main body rotates 30 degrees with respect to a specific axis in a state in which an image corresponding to the first reproduction time (0:00) is output to the screen 220, do. When the main body is restored to its original position after 5 seconds, an image corresponding to the second reproduction time (5:00) is output to the screen 220.

That is, when the main body rotates at a predetermined angle with respect to a specific axis, the control unit 180 can rewind or fast-forward the currently reproduced moving image, and can change the rate of change of the playback point based on the predetermined angle.

When the main body rotates at a predetermined angle with respect to the second axis, the controller 180 may vary the magnification or reduction ratio of the first image according to the predetermined angle. For example, as shown in FIG. 7B, when the main body rotates 30 degrees with respect to the axis different from the axis described in FIG. 7A in a state in which an image corresponding to the first reproduction time (0:00) is output to the screen 220, The enlarged image is output to the display unit 220.

That is, when the main body rotates at a predetermined angle with respect to a specific axis, the controller 180 enlarges or reduces the currently reproduced moving image, and may vary the enlargement or reduction ratio based on the predetermined angle.

As described above, the mobile terminal according to the present invention changes an image or a moving image projected on the screen according to the movement of the main body. Thus, the user can control the image projected on the screen without applying the touch input.

Hereinafter, an embodiment in which the image projected on the screen is changed only when the movement of the main body satisfies predetermined conditions even if the main body moves, will be described.

8A and 8B are conceptual diagrams showing an embodiment for changing an image projected on a screen only when the movement of the main body satisfies predetermined conditions.

The control unit 180 controls the display unit 151 to project the second image onto the screen 220 only when the motion of the main body satisfies a preset condition, If it is not satisfied, the display unit 151 may be controlled to maintain the first image.
