Abstract

A three-dimensional (3D) video apparatus and a method of providing an OSD object applied thereto are provided. The 3D video apparatus includes an on-screen display (OSD) generation unit which receives an OSD object and generates a reduced OSD object to be displayed on the 3D image on a screen, wherein the reduced OSD object is smaller than the received OSD object. An OSD insertion unit inserts the reduced OSD object into input 3D image data.

Claims

1. A three-dimensional (3D) video apparatus for representing a 3D image, the apparatus comprising:

a receiving unit which receives a 3D image data comprising a left-eye image data and a right-eye image data in a frame;

an on-screen display (OSD) generation unit which receives an OSD object and generates a reduced OSD object by reducing a size of the received OSD object to correspond to an image size of one of the left-eye image data and the right-eye image data, wherein the reduced OSD object is smaller than the received OSD object;

an OSD insertion unit which inserts the reduced OSD object into at least one of the left-eye image data and the right-eye image data to be displayed on the 3D image on a screen;

a 3D representation unit which generates one of a left-eye image and a right-eye image; and

an image output unit which outputs the generated left-eye image or the generated right-eye image once per the 3D image data frame, or outputs the generated left-eye image or the right-eye image repeatedly corresponding to a screen display frequency of the 3D video apparatus.

2. The 3D video apparatus of claim 1, wherein the 3D representation unit generates the left-eye image based on the left-eye image data if the OSD object generated by the OSD insertion unit is inserted into the left-eye image data, and the image output unit outputs the generated left-eye image instead of the right-eye image.

3. The 3D video apparatus of claim 1, wherein the 3D representation unit generates the right-eye image based on the right-eye image data if the generated OSD object is inserted into the right-eye image data, and the image output unit outputs the generated right-eye image instead of the left-eye image.

4. The 3D video apparatus of claim 1, wherein the OSD generation unit generates the reduced OSD object by reducing the size of the received OSD object in at least one of a horizontal direction and a vertical direction.

5. The 3D video apparatus of claim 4, wherein the OSD generation unit generates the reduced OSD object by reducing the size of the received OSD object in the horizontal direction and the vertical direction, and the OSD insertion unit inserts the reduced OSD object into a 3D image data region, which corresponds to one of four divided screen regions that is positioned on a left upper part of the screen.

6. A method of providing an on-screen display (OSD) in a three-dimensional (3D) video apparatus, the method comprising:

receiving 3D image data including a left-eye image data and a right-eye image data in a frame;

receiving an OSD object;

reducing a size of the received OSD object to correspond to an image size of one of the left-eye image data and the right-eye image data, wherein the reduced OSD object is smaller than the received OSD object;

inserting the reduced OSD object into at least one of the left-eye image data and the right-eye image data to be displayed on the 3D image on a screen;

generating one of a left-eye image and a right-eye image; and

outputting the generated left-eye image or the generated right-eye image once per the 3D image data frame, or outputting the generated left-eye image or the right-eye image repeatedly corresponding to a screen display frequency of the 3D video apparatus.

7. The method of providing an OSD of claim 6, wherein the generating comprises generating one of the left-eye image and the right-eye image comprises generating the left-eye image based on the left-eye image data if the generated OSD object is inserted into the left-eye image data, and

the outputting the generated left-eye image or the generated right-eye image comprises outputting the generated left-eye image instead of the right-eye image.

8. The method of providing an OSD of claim 6, wherein the generating one of the left-eye image and the right-eye image comprises generating the right-eye image based on the right-eye image data if the generated OSD object is inserted into the right-eye image data, and

the outputting the generated left-eye image or the generated right-eye image comprises outputting the generated right-eye image instead of the left-eye image.

9. The method of claim 6, wherein the generating the reduced OSD object comprises reducing the size of the received OSD object in at least one of a horizontal direction and a vertical direction.

10. The method of claim 9, wherein the generating the reduced OSD object further comprises reducing the size of the received OSD object in both of the horizontal direction and the vertical direction.

11. The method of claim 10, wherein the inserting the reduced OSD object comprises inserting the reduced OSD object into an image data region, which corresponds to one of four divided screen regions of the screen that is positioned on a left upper part of the screen.

12. A three-dimensional (3D) video apparatus for representing a 3D image, the apparatus comprising:

an on-screen display (OSD) generation unit which generates an OSD;

a 3D representation unit which generates one of a left-eye image and a right-eye image to be displayed on a screen using input 3D image data if the OSD object is generated;

an OSD insertion unit which inserts the generated OSD into the generated left-eye image or right-eye image; and

an image output unit which outputs the left-eye image or right-eye image into which the OSD is inserted once per the input 3D image data, or outputs the left-eye image or right-eye image into which the OSD object is inserted repeatedly corresponding to a screen display frequency of the 3D video apparatus.

13. A method of providing an on-screen display (OSD) in a three-dimensional (3D) video apparatus, the method comprising:

generating an OSD object;

generating one of a left-eye image and a right-eye image to be displayed on a screen using input 3D image data;

inserting the generated OSD object into the generated left-eye image or right-eye image; and

outputting the left-eye image or the right-eye image into which the OSD object is inserted once per the input 3D image data, or outputs the left-eye image or the right-eye image into which the OSD object is inserted repeatedly corresponding to a screen display frequency of the 3D video apparatus.
