The flow chart shown. Hereinafter, for convenience of understanding and explanation, the user inputs an arbitrary content execution command from the user through the input unit 330, and the portable terminal 300 receives and executes the corresponding content from the content providing device 380 through a communication network. It is assumed that it is being described. In addition, assuming that the user currently holds the portable terminal 300 in a vertical direction as shown in FIG. 4A, the shape of the portable terminal 300 is changed by rotating 90 ° counterclockwise as shown in FIG. 4B. Let's explain.

In operation 610, the sensor unit 315 detects a position change according to rotation of the portable terminal 300 in a counterclockwise or clockwise direction, generates measurement data, and transmits the measured data to the preprocessor 320.

For example, when the sensor unit 315 includes a horizontal sensor and a vertical sensor, the horizontal sensor and the vertical sensor may be attached to the lower side or the left and right sides of the portable terminal. The measurement data may be generated and transmitted to the preprocessor 320 according to the degree of rotation in the counterclockwise or clockwise direction of 300. For example, the measurement data may be data corresponding to a rotation angle according to the degree of rotation in the counterclockwise or clockwise direction of the portable terminal 300.

In operation 615, the preprocessing unit 320 removes an error (for example, data distortion at the time of measurement) added to the measurement (or generation) point of time of the measurement data input from the sensor unit 315 by using a predetermined algorithm. Transfer to the controller 350. In addition, the preprocessor 320 may amplify the specific data from which the error is removed to correspond to a predetermined size and output the amplified data to the controller 350.

In operation 620, the controller 350 analyzes the measurement data input from the preprocessor 320 to determine an image output type, generates image conversion information corresponding thereto, and transmits the image conversion information to the image correction unit 325.

In this case, the controller 350 may store movement information on a movement or position change immediately before the portable terminal 300 in a storage medium such as a register or a buffer.

For example, if the image to be output through the display unit 345 of the portable terminal 300 includes stereoscopic information (for example, includes depth information, or 3D image information). The image change information may include side information of an image to be viewed according to the motion information of the portable terminal 300.

In addition, in the present specification, the control unit 350 analyzes the motion information and compares the motion information with the previous motion information to change it horizontally or vertically (for example, in the state shown in FIG. The image change information may be transmitted to the image correcting unit 325 only when the shape is changed or when the shape is changed to FIG. 4A in the same state as in FIG. 4B. 325).

In operation 625, the image correction unit 325 corrects the image information so that the image information corresponding to the content received through the communication network under the control of the control unit 350 corresponds to the image conversion information input from the control unit 350 to output the output image. Switch.

For example, suppose that the user rotates the portable terminal 300 by 90 ° counterclockwise as shown in FIG. 4B while the image corresponding to the content output through the display unit 345 is as shown in FIG. 4A. At this time, the control unit 350 converts the width and length of the display unit 345. That is, in FIG. 4A, if 410 is recognized as the horizontal axis and 420 is recognized as the vertical axis, in the state of FIG. 4B, 430 is recognized as the horizontal axis and 440 is recognized as the vertical axis. Accordingly, the control unit 350 analyzes the motion information, generates corresponding image conversion information by using the horizontal axis, the vertical axis, the horizontal axis length information, the vertical axis length information, and the like of the portable terminal to the image correction unit 325. I can deliver it. The image corrector 325 receiving the image change information may convert the output image to correspond to the image change information. For example, assume that the horizontal size is 240B (Byte) and the vertical size is 320B (Byte), for example, in the display unit of FIG. 4A. In this case, as shown in FIG. 4B, when the portable terminal 300 moves in the counterclockwise direction, the controller 350 may use the horizontal size of the display unit 345 as 320B (Byte) and the vertical size as 240B (Byte). Will be recognized. Accordingly, the controller 350 transmits the image conversion information to the image corrector 325 so that the image is output to correspond to the changed size of the display unit 345 and displays the image data to be output by the size of the display unit 345 or the display unit 345. Can be converted to correspond to the direction of.

In operation 630, the image correction unit 325 outputs the image information corrected according to the size or direction of the display unit 345 to the display unit 345 through the control unit 350 in step 625. 4A to 4D illustrate examples of switching and outputting image data output to the display unit 345 according to the displacement of the portable terminal 300 according to the counterclockwise or clockwise rotation of the portable terminal 300. have.

7 is a flowchart illustrating a method for receiving and displaying another side of a character having stereoscopic information output in response to a movement of a portable terminal from a content providing device 380 connected through a communication network according to an exemplary embodiment of the present invention. . Hereinafter, the portable terminal 300 according to the present invention is equipped with a geomagnetic sensor and an acceleration sensor to measure the movement information of the portable terminal to display image data on the other side of the character having stereoscopic information corresponding to the movement. Let's explain. Here, the stereoscopic information includes information for stereoscopically displaying a two-dimensional character, such as depth information, for example, or each face (for example, front, rear, left, and right sides) of the character. , Upper surface, lower surface, etc.) or all three pieces of information that can be produced in three dimensions and display image data corresponding to various aspects of the character according to the user's request. . Hereinafter, for convenience of understanding and explanation, it is assumed that the image data of the character initially provided from the content providing device 380 to the portable terminal is image data corresponding to the front side, and then corresponds to the movement of the portable terminal 300. It will be described on the assumption that the image data for the other side of the character is provided from the content providing device 380 through the communication network and displayed on the portable terminal 300. Hereinafter, the range of stereoscopic information of the character to be output to the display unit 345 corresponding to the movement of the portable terminal 300 (for example, the movement according to the degree of rotation in the X-axis, Y-axis, Z-axis and one or more axes). The following description focuses on receiving the corresponding image data (or image data) from the content providing device 380 through the communication network and displaying the image data (or image data) on the portable terminal 300. However, the portable terminal 300 according to the present invention may determine the range of stereoscopic information to be output of the character stored in the storage unit 342, and read and display the corresponding image data from the storage unit 342. . Of course, when the character is authored in three dimensions and has three-dimensional coordinate data, the movement of the portable terminal 300 (for example, the X-axis, the Y-axis, the Z-axis, and the axis by one or more combinations) It is natural that the other side of the character may be output depending on the displacement of the movement according to the degree of rotation.

In operation 710, the sensor unit 315 may move by the movement of the portable terminal 300 (for example, up, down, left, right, etc.) (for example, X, Y, Z, and one). Motion according to the degree of rotation to the axis due to the above combination)) to generate the measurement data and transmit it to the preprocessor 320. For example, assuming that the sensor unit 315 is equipped with a geomagnetic sensor, an acceleration sensor, etc., the sensor unit 315 detects magnetic energy and measures magnetic energy of three axes to measure measurement data corresponding to the movement at the time of observation. It can be generated and delivered to the preprocessor 320.

For example, suppose that the user rotates the portable terminal 300 by about 15 ° to the left side (for example, in the state shown in FIG. 5 (a), the portable terminal 300 is shown in FIG. 5 (b)). Suppose you rotated 15 ° to the left). The sensor unit 315 detects the degree of rotation of the portable terminal 300 by using a sensor (for example, a geomagnetic sensor, an acceleration sensor, etc.) to generate corresponding measurement data and transmit the measured data to the preprocessor 320. Can be.

In operation 715, the preprocessing unit 320 may perform a pre-processing process on the measurement data input from the sensor unit 315 (for example, when the movement of the portable terminal 300 is measured through the sensor unit 315). Error data or distortion data added by a factor (for example, strong or weak magnetic object, etc.) is performed and transmitted to the controller 350.

In operation 720, the control unit 350 analyzes the measurement data that has undergone the preprocessing process from the preprocessor 320, according to the degree of rotation of the portable terminal 300 in the X, Y, Z, and at least one combination thereof. The range of stereoscopic information to be output is determined according to the displacement, and the image request information according to the determined stereoscopic information is generated and transmitted to the content providing device 380 through the transceiver 310.

For example, assume that the portable terminal 300 is rotated as shown in FIG. 5B in a state as shown in FIG. 5A. For convenience of understanding and explanation, assume that the rotation shown in FIG. 5A to FIG. 5B is rotated about 15 ° to the left, for example. In this case, the portable terminal 300 compares the measurement data with the position information of the previous portable terminal 300 (for example, assume that the positions of 0, 0, and 0 respectively based on the X, Y, and Z axes). For example, since it rotates 15 degrees about the Y axis, the portable terminal 300 determines the image data to be displayed as image data corresponding to the left side of the character. Accordingly, the controller 350 of the portable terminal 300 may request information about image data corresponding to the left side of the character (hereinafter, image data according to a range of stereoscopic information to be output of the character according to the movement of the portable terminal 300). May be referred to as "image request information", and may be transmitted to the content providing device 380.

Here, if the character is not image data for the character provided from the content providing device 380, but is image data stored in the storage unit 342, the controller 350 may have a left side of the character stored in the storage unit 342. The image data corresponding thereto may be read and output through the display unit 345.

In operation 725, the content providing device 380 may correspond to image data corresponding to a range of stereoscopic information (eg, on the other side of the character) of the character corresponding to the image request information received from the portable terminal 300 through a communication network. Extract it and transmit it to the portable terminal 300 through a communication network. For example, the content providing device 380 may include a stereoscopic information database (not shown) that stores stereoscopic information of the character, and analyzes the image request information received from the portable terminal 300 to correspond to the character. The image data corresponding to the range of stereoscopic information may be read from the stereoscopic information database (not shown) and transmitted to the portable terminal 300.

In operation 730, the portable terminal 300 receives image data corresponding to a range (eg, another surface) of the stereoscopic information of the character from the content providing device 380 and outputs the image data through the display unit 345.

5 (a) to 5 (f) corresponding to the other side of the character (eg, front, rear, left, right, top, bottom, etc.) corresponding to the movement of the portable terminal 300 An example of outputting image data through the display unit 345 is illustrated. For example, if the portable terminal 300 is rotated or moved to the left while the front image data of the character is being output as shown in FIG. 5A, the left side of the character as illustrated in FIG. 5B. The image data may be requested to the content providing device 380 to receive and output the corresponding image data.

As described above, the portable terminal 300 according to the present invention detects the movement according to the rotation in the counterclockwise and clockwise directions, and outputs the image by switching the image according to the direction of the display unit 345 of the portable terminal 300. can do. In addition, image data (eg, other surface) according to a range of stereoscopic information to be output corresponding to the degree of rotation of the portable terminal 300 in the X, Y, Z, and axes by one or more combinations. Can be displayed.
