In addition, the way of wearing glasses is divided into a passive (active) method and an active (active) method. The passive method distinguishes between a left image and a right image by using a polarization filter. Or, wearing blue and red sunglasses on both eyes is also passive. The active method is a method of distinguishing left and right eyes using a liquid crystal shutter, and distinguishing a left image and a right image by sequentially covering the left eye (left eye) and the right eye (right eye) in time. In other words, the active method is a method of periodically wearing a glasses with an electronic shutter that is periodically repeated and synchronized with the time-divided screen, also referred to as a time split type or a shuttered glass method. . Representatives known as a glasses-free method without wearing glasses include a lenticular method in which a lenticular lens plate in which a cylindrical lens array is vertically arranged in front of the image panel, and a periodic slit in the upper part of the image panel.

The signal Vsync is generated and output to an IR emitter (not shown) in the shutter glasses so that the shutter glasses 121 can watch in synchronization with the display.

The IR emitter receives the sync signal generated by the output formatter 119 and outputs the sync signal to the light receiving unit (not shown) in the shutter glasses 121, and the shutter glasses 150 pass through the IR emitter (not shown) through the light receiving unit. By adjusting the shutter open period according to the received synchronization signal, it is possible to match the synchronization of the 3D image data output from the display unit 120.

2 is a diagram illustrating a configuration of shutter glasses according to an embodiment of the present invention.

Referring to FIG. 2, the shutter glasses include a left eye shutter liquid crystal panel 200 and a right eye shutter liquid crystal panel 230. The shutter liquid crystal panels 200 and 230 perform a function of simply passing or blocking light according to the source driving voltage. When the left image is displayed on the display surface of the digital broadcast receiver, the left eye shutter liquid crystal panel 200 passes the light and the right eye shutter liquid crystal panel 230 blocks the light transmission, so that the left image is transmitted only to the left eye of the user of the glasses. To be. On the other hand, when the right image is displayed on the display surface of the digital broadcast receiver, the left eye shutter liquid crystal panel 200 blocks the light transmission, and the right eye shutter liquid crystal panel 230 passes the light, so that the right image is the right eye of the user. To be delivered only to.

In this process, the infrared receiver 160 of the shutter glasses 150 converts the infrared signal received from the digital broadcast receiver into an electrical signal and provides it to the controller 170. The controller 170 controls the left eye shutter liquid crystal panel 200 and the right eye shutter liquid crystal panel 230 to be turned on and off alternately according to the synchronization reference signal.

In addition, the position sensor 180 of the shutter glasses senses information for detecting the position of the user. The sensing information is transmitted by the infrared transceiver 160 to the digital broadcast receiver. According to an exemplary embodiment, the shutter glasses may include a camera module (not shown) for determining the position of the user.

Meanwhile, the 3D image data may be implemented in 3D by various methods such as giving a tilt to a depth or giving a 3D effect. Hereinafter, a method of giving depth among the above methods Briefly describe.

The digital broadcast receiver processes three-dimensional image data using a stereoscopic principle. That is, when one object is photographed by two cameras of different positions, the left image data and the right image data are generated, and each generated image data is inputted separately so as to be orthogonal to each other in the left and right eyes of the person. It is a principle that the 3D image is generated by combining the image data inputted into the left and right eyes of the brain. In the above, the fact that the image data is arranged to be orthogonal to each other means that each image data does not interfere with each other.

FIG. 3 is a diagram illustrating perspective according to a gap or parallax (hereinafter, referred to as a gap) between the left image data and the right image data.

FIG. 3 (a) illustrates an upper position 303 in which both data are combined when the distance between the right image data 301 and the left image data 302 is narrow, and FIG. 3 (b) illustrates the right image data ( 311 and the left image data 312 have been described, the position of the upper image 313 to form.

3 (a) to 3 (b) show the degree of perspective at which different images are formed at different positions according to the interval between the left image data and the right image data in the image signal processing apparatus.

Referring to FIG. 3 (a), the upper side draws extension lines R1 and R2 facing one side and the other side of the right image data 301 to the right eye, and the left side faces the other side to one side of the left image data 302. When drawing the extension lines L1 and L2, the extension line R1 for the right image data and the extension line L1 for the left image data cross each other at a distance d1 from the right eye and the left eye at a point 303. Bears.

Referring to FIG. 3B, the image is based on the foregoing description in FIG. 3A, and the extension line R3 for the right image data and the extension line L3 for the left image data have a predetermined distance from the right eye and the left eye. at point 313 intersecting each other at d2).

Here, comparing d1 in FIG. 3 (a) and d2 in FIG. 3 (b) which show the distances from the left and right eyes to the positions 303 and 313 where the images are formed, the distance d1 is greater than the left and right eyes than d2. far. That is, the image in Fig. 3A is formed at a distance farther from the left and right eyes than the image in Fig. 3B.

This is due to the distance (east-west direction with reference to the drawing) between the right image data and the left image data.

For example, the interval between the right image data 301 and the left image data 302 in FIG. 3A is the interval between the right image data 303 and the left image data 304 in FIG. 3B. Relatively narrow compared with

Therefore, inferring based on Figs. 3 (a) and 3 (b), as the interval of each image data becomes narrower, the image formed by the combination of the left image data and the right image data appears to be far from the human eye.

4 is a diagram illustrating an example of a method of implementing a 3D UI in relation to the present invention.

4 (a) and 4 (b) are implemented as a three-dimensional image of the UI itself containing a plurality of items, in the case of Figure 4 (a) the left image data 401 and the right image data constituting the UI In the case of FIG. 4B, the interval between the left image data 404 and the right image data 405 constituting the UI is wide.

Accordingly, the 3D UIs 403 and 406 implemented according to the intervals of the respective image data in FIGS. 4 (a) and 4 (b) are based on the above-described principle of FIG. 3. The image is located far from the human eye and looks far away, and the 3D UI 406 implemented in FIG. That is, by adjusting the distance between the left image data and the right image data constituting the UI, it is possible to give an appropriate depth to the UI.

Hereinafter, an embodiment of providing a user interface for guiding a viewing position in a digital broadcasting receiver for providing such a 3D image will be described in detail.

5 is a flowchart illustrating a viewing guide process of a digital broadcast receiver for providing 3D content according to an embodiment of the present invention.

Referring to FIG. 5, when the digital broadcast receiver is selected as the 3D output mode in step S501, the output formatter 119 may convert the 3D content into a 3D format according to the format and the output frequency of the display 120 as described above. The shutter glasses adjust the shutter opening period according to a synchronization signal received through an IR emitter (not shown) through the light receiving unit, so as to synchronize the three-dimensional image data output from the display unit of the digital broadcasting receiver.

In step S502, the digital broadcast receiver determines the user location. According to the present invention, a method of determining a user location may be implemented in various ways.

In one embodiment, when power is supplied to the shutter glasses, the shutter glasses sense the information for detecting the user's position in the position sensor, and then transmit the sensed sensing information to the digital broadcast receiver, and the digital broadcast receiver shutter glasses The sensor may receive sensing information and determine the position of the shutter glasses, that is, the user position, using the received sensing information.

Specifically, the IR broadcast module may be mounted on the digital broadcast receiver, the IR camera may be mounted on the shutter glasses, and the position of the shutter glasses may be determined by analyzing image data of the IR transmitter module photographed by the IR camera. In this case, when a plurality of IR transmitting modules are mounted, the positions of the shutter glasses may be determined by analyzing images of the plurality of IR transmitting modules from the images photographed by the shutter glasses, and the positions of the shutter glasses may be used as the user position. .

In addition, according to an embodiment, the digital broadcast receiver may detect the position of the shutter glasses or the user to determine the position of the user. For example, after mounting an IR sensor on the digital broadcast receiver, the position of the shutter glasses may be determined by detecting an IR signal transmitted from the shutter glasses to calculate a distance from the x, y, and z axes.

In addition, according to another embodiment of the present invention, after capturing an image with a camera module in a digital broadcasting receiver, recognizing a predetermined pattern (shutter glasses image or user's face) in the photographed image, and then measuring the size and angle of the recognized pattern. The location of the user may be determined according to the analysis.

In step S502, the digital broadcast receiver determines whether the determined user's position is out of the 3D viewing range.

For example, the digital broadcasting receiver may determine the user's position and (x, y, z) coordinate values from the sensing information received from the shutter glasses, and the user's position (x, y, z) coordinate values may be three-dimensional. It may be determined whether the coordinate value is included in the viewing range.

The 3D viewing range means an area where 3D contents can be normally viewed when located within the range, and according to an embodiment, a predetermined area in front of the digital broadcasting receiver may be set as the 3D viewing range.

If it is determined in step S503 that the user's location is out of the 3D viewing range, the digital broadcasting receiver generates a 3D image corresponding to the user in step S504 and then determines in step S505. Outputs the 3D image to the user's location.

In addition, even if it is determined that the user's position has not deviated from the three-dimensional viewing range as a result of the determination in step S503, when the user selects the view of the user position in step S506, the digital broadcast receiver in step S504 After generating the 3D image, the 3D image is output to the user's position in step S505.

The three-dimensional image corresponding to the user is a shutter. 3D image data that may be output to the user's position determined by the information received from the glasses.

According to an embodiment, when sensing information sensed by each of the plurality of shutter glasses is received, the 3D image data may be generated to correspond to each of the shutter glasses, and may be generated in different shapes.

According to an exemplary embodiment, the digital broadcast receiver may allow the prestored left image data and right image data to be output at (x, y, z) coordinate values which are positions of the user.

In this case, the digital broadcast receiver may output the left image data and the right image data to have a depth value equal to z which is a vertical coordinate (a vertical distance between the digital broadcast receiver and the shutter glasses).

In addition, according to an embodiment, the digital broadcasting receiver prestores left image data and right image data corresponding to an arbitrary (x, y) value, and then stores the left image data corresponding to the (x, y) value of the user position and The image data may be read and output to have a depth value equal to z.

Also, according to an embodiment, in step S505, the digital broadcast receiver may output a 3D boundary image representing the 3D viewing range. The 3D boundary image may be 3D image data generated to inform the 3D viewing range so that the user can intuitively recognize the 3D viewing range.

In addition, according to an embodiment, if it is determined in step S503 that the user's position is out of the 3D viewing range, the digital broadcasting receiver outputs a warning sound to an audio output means (amplifier, etc.) or generates a guide message in the OSD. Or LEDs provided in the digital broadcasting receiver.

Further, according to an embodiment, when it is determined that a specific user deviates from the 3D viewing range for a predetermined time or more, the digital broadcasting receiver turns off the power of the digital broadcasting receiver to minimize unnecessary power consumption or 2D output mode. By switching to the output mode, you can avoid unnecessary 3D output conversions.

Even when the digital broadcasting receiver is turned off because the user is determined to be out of the 3D viewing range for a predetermined time or more, the position determination module for determining the position of the user may be supplied with power, and the user may reenter the 3D viewing range. If it is determined that the power-on signal is transmitted to the controller, the digital broadcast receiver may be implemented to be turned on.

Similarly, if the user is determined to deviate from the three-dimensional viewing range for a predetermined time or more, and the output mode of the digital broadcasting receiver is switched from the 3D output mode to the 2D output mode, the user is determined to re-enter the 3D viewing range. It can also be controlled to reset the output mode.

Accordingly, the present invention provides a three-dimensional user interface that provides information about the user location in the digital broadcast receiver provided with the three-dimensional content, so that the user can conveniently view the three-dimensional content at the optimal location It is effective.

In addition, the present invention provides a three-dimensional boundary image so that the three-dimensional viewing range can be intuitively recognized, thereby enabling the user to conveniently use the three-dimensional content in the digital broadcasting receiver.

Referring to FIG. 12, when it is determined that the user's position 1203 is out of the 3D viewing range, the digital broadcasting receiver 1200 according to an embodiment of the present invention may include the 3D boundary images 1201 and 1202. The OSD 1204 including the guide message may be generated and output. In addition, the digital broadcast receiver may output a warning sound to an audio output means (amplifier or the like).

According to an embodiment, when it is determined that the determined position of the shutter glasses deviates from the 3D viewing range for a predetermined time or more, the digital broadcasting receiver may turn off the power of the digital broadcasting receiver to minimize unnecessary power consumption. The 3D output mode can be switched to the 2D output mode to prevent unnecessary 3D output conversion.

At this time, even if the digital broadcast receiver is turned off because it is determined that the user is out of the 3D viewing range for a predetermined time or more, power may be supplied to the position determining module for determining the position of the user. If it is determined to re-enter the network, it may be implemented to transmit the power-on signal to the controller from the rainy season determination module so that the power of the digital broadcasting receiver is turned on.

Similarly, if the user is determined to deviate from the three-dimensional viewing range for a predetermined time or more, and the output mode of the digital broadcasting receiver is switched from the 3D output mode to the 2D output mode, the user is determined to re-enter the 3D viewing range. It can also be controlled to reset the output mode.

As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above-described embodiments, which can be variously modified and modified by those skilled in the art to which the present invention pertains. Modifications are possible. Accordingly, the spirit of the present invention should be understood only by the claims set forth below, and all equivalent or equivalent modifications thereof will belong to the scope of the present invention.
