- the adjustment of the size may be performed by multiplying the font size of the caption or the size of the image by the distortion compensation coefficient. That is, the caption finally displayed is output by adjusting the size of the caption in proportion to the sense of distance, so that the caption located in front of the screen is smaller, the larger the caption is located behind the screen.
- FIG. 7 is a flowchart illustrating a 3D object display method according to an embodiment of the present invention.
- the 3D object display method of FIG. 7 illustrates a 3D object display method performed by the broadcast receiver illustrated and described with reference to FIGS. 5 to 6.
- the broadcast receiver receives and demodulates a broadcast signal including 3D object data using the broadcast signal receiver (S7010).
- the 3D object is an image other than the main video, and represents an image such as a caption, subtitle, menu, logo, etc. provided to the user.
- the 3D object data may be included in the header area of the video data as described above or may be received by a separate ES.
- the broadcast receiver decodes 3D object data using a decoder in operation S7020.
- the 3D object data includes image information on at least one of text, graphics, and video of the 3D object, positional information on a position on the screen on which the 3D object is to be output, and disparity information or depth information necessary to represent the 3D effect.
- the location information may include coordinate information where the 3D object is located on the screen.
- the broadcast receiver calculates a distortion compensation coefficient for compensating for size distortion according to the 3D display of the 3D object by using a graphics engine or a 3D graphics processor (S7030).
- the broadcast receiver calculates a parallax value from the disparity value when the disparity information is included in the 3D object data by using the above-described equations.
- the distortion compensation coefficient may be calculated from the parallax value and the binocular disparity through the above-described equations.
- the binocular disparity may use a preset default value (for example, 6.5 cm), a different value according to race, gender, and age, and may be used by receiving binocular disparity according to a user.
- the distortion information may be directly calculated using the depth information.
- the distortion compensation coefficient F K / X of Equation 3
- K represents a distance between the screen and the viewer
- X corresponds to a value obtained by converting the depth value D into a physical distance. That is, when the depth information is defined as a value between 0 and 255, there is a physical X that the user perceives when displaying on the actual 3D screen.
- the broadcast receiver can calculate the distance at which the user perceives the depth coded in the image, or can obtain the X value using the depth mapping information that maps the depth to the physical distance. Compensation factors may also be calculated.
- D corresponds to a physical distance value in which the depth value is mapped to the distance between the screen and the 3D object.
- the distance between the screen and the viewer may be used as a preset value or may be input from the user.
- the broadcast receiver adjusts the size of the 3D object using the distortion compensation coefficient in the graphics engine or the 3D graphics processor (S7040).
- the adjustment of the size may be performed by multiplying the font size of the caption or the size of the image by the distortion compensation coefficient. That is, the size of the 3D object is adjusted by the size of the font size or the horizontal / vertical size of the image multiplied by the distortion compensation coefficient.
- the 3D object finally displayed is output by adjusting the caption size in proportion to the sense of distance, the smaller the caption positioned in front of the screen, the larger the caption positioned behind the screen.
- the broadcast receiver outputs the adjusted 3D object (S7050).
- the size adjustment of the above-described 3D object is automatically performed.
- the size of the 3D object can be adjusted according to the user's selection. That is, the UI for adjusting the size of the 3D object according to the user input may be displayed, and the size of the 3D object may be adjusted according to the user's selection.
- the user may receive a size change corresponding thereto and adjust the size of the 3D object by reflecting the size change in the distortion compensation coefficient.
- FIG. 8 is a diagram illustrating a UI for adjusting the size of a 3D object according to an embodiment of the present invention.
- the 3D object is represented as a caption.
- the broadcast receiver may display a UI for caption size change, such as the screen 8010.
- a UI may be activated by a user input or automatically activated when displaying a caption.
- the broadcast receiver may display the UI of the screen 8020.
- the user may adjust the caption size by moving the arrow as a dotted line through the user input means.
- the broadcast receiver may adjust the caption size by performing steps subsequent to operation S7030 of FIG. 7.
- the step of displaying the UI of such a 3D object and receiving the caption size adjustment from the user may be performed between steps S7020 and S7030 of FIG. 7 or between steps S7030 and S7040. have.
- the present invention may be applied in whole or in part to a digital broadcasting system.
