Abstract

Disclosed herein are a method and apparatus for normalizing the size of content in a multi-projection theater and a computer-readable recording medium. The method may include receiving theater parameters stored in a database, computing the scale factor of an image projected on a main screen based on the received theater parameters, controlling the image projected on the main screen by applying the computed scale factor to the image, and controlling the scale of an image projected on a sub-screen according to the controlled image of the main screen.

Claims

1. A method for normalizing a size of content in a multi-projection theater, the method performed by an apparatus having a scale factor operation module, a main screen image control module, a sub-screen image control module, and a database, the method comprising:

receiving by the scale factor operation module, theater parameters of the multi-projection theater stored in a database;

computing, by the scale factor operation module, a scale factor of an image data projected on a main screen based on the received theater parameters;

adjusting, by the main screen image control module, the image data projected on the main screen by applying the computed scale factor to the image data; and

adjusting, by the sub-screen image control module, a scale of an image data projected on a sub-screen according to the adjusted image data projected on the main screen,

wherein the theater parameters include information on a size of the multi-projection theater, and

wherein the image data projected on the main screen and the image data projected on the sub-screen are adjusted so that a difference between pixel sizes or ratios of the both image data is a predetermined reference value or less based on the received theater parameters.

2. The method of claim 1, wherein the image data projected on the sub-screen is adjusted so that the adjusted image data projected on the main screen and the sub-screen have an identical height.

3. The method of claim 1, further comprising;

adjusting, by the sub-screen image control module, a location of the image data projected on the sub-screen by applying the received theater parameters if the main screen and the sub-screen are not contiguous.

4. The method of claim 3, wherein the location of the image data projected on the sub-screen is adjusted based on a space between the main screen and the sub-screen.

5. The method of claim 1, wherein if the main screen and the sub-screen are not contiguous, the adjusting the image data projected on the main screen comprises:

enlarging the image data projected on the main screen by applying the received theater parameters, and cropping the enlarged image data according to a size of the main screen.

6. The method of claim 5, wherein the image data projected on the main screen is enlarged by a ratio of a size of a theater and the size of the main screen.

7. The method of claim 1, wherein the adjusting the image data projected on the main screen comprises adjusting a width to length ratio of the image data projected on the main screen per pixel.

8. An apparatus for normalizing a size of content in a multi-projection theater, comprising:

a database configured to store theater parameters; and

a control unit configured to receive the theater parameters from the database and control images projected on a main screen and a sub-screen,

wherein the control unit comprise;

a scale factor operation module configured to compute a scale factor of the image data projected on the main screen based on the received theater parameters;

a main screen image control module configured to adjust the image data projected on the main screen by incorporating the computed scale factor into the image data projected on the main screen; and

a sub-screen image control module configured to adjust a scale of the image data projected on the sub-screen according to the adjusted image data projected on the main screen,

wherein the theater parameters include information on a size of the multi-projection theater, and

wherein the image data projected on the main screen and the image data projected on the sub-screen are adjusted so that a difference between pixel sizes or ratios of the both image data is a predetermined reference value or less based on the received theater parameters.

9. The apparatus of claim 8, wherein the sub-screen image control module is configured to adjust the image data projected on the sub-screen so that the adjusted image data projected on the main screen and the sub-screen have an identical height.

10. The apparatus of claim 8, wherein the sub-screen image control module is configured to adjust a location of the image data projected on the sub-screen by applying the received theater parameters if the main screen and the sub-screen are not contiguous as a result of analysis of the received theater parameters.

11. The apparatus of claim 10, wherein the sub-screen image control module is configured to adjust the location of the image data projected on the sub-screen based on a space between the main screen and the sub-screen.

12. The apparatus of claim 8, wherein if the main screen and the sub-screen are not contiguous, the main screen image control module is configured to enlarge the image data projected on the main screen by applying the received theater parameters and to crop the enlarged image data according to a size of the main screen.

13. The apparatus of claim 12, wherein the image data projected on the main screen is enlarged by a ratio of a size of a theater and the size of the main screen.

14. The apparatus of claim 8, wherein the main screen image control module is configured to adjust a width to length ratio of the image data projected on the main screen per pixel.

15. A non-transitory computer-readable recording medium recording a computer program for executing a method for normalizing a size of content in a multi-projection theater, the method performed by an apparatus having a scale factor operation module, a main screen image control module, a sub-screen image control module, and a database, the method comprising:

receiving, by the scale factor operation module, theater parameters of the multi-projection theater stored in a database;

computing, by the scale factor operation module, a scale factor of an image data projected on a main screen based on the received theater parameters;

adjusting, by the main screen image control module, the image data projected on the main screen by applying the computed scale factor to the image data; and

adjusting, by the sub-screen image control module, a scale of an image data projected on a sub-screen according to the adjusted image data projected on the main screen,

wherein the theater parameters include information on a size of the multi-projection theater, and

wherein the image data projected on the main screen and the image data projected on the subscreen are adjusted so that a difference between pixel sizes or ratios of the both image data is a pre-determined reference value or less based on the received theater parameters.
