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 project on a main screen based on the received theater parameters, controlling the image projected on the main screen by incorporating the computed scale factor into the image, and controlling an image projected on a sub-screen so that the height or width of at least any one of images of sub-screens having a different pixel size or ratio from the controlled image of the main screen is identical with a height or width of the controlled image of the main screen.

Claims

1. A method of normalizing a size of content in a multi-projection theater, the method comprising:

receiving theater parameters stored in a database;

computing a scale factor of an image project on a main screen based on the received theater parameters;

controlling the image projected on the main screen by incorporating the computed scale factor into the image; and

controlling an image projected on a sub-screen so that a height or width of at least any one of images of sub-screens having a different pixel size or ratio from the controlled image of the main screen is identical with a height or width of the controlled image of the main screen.

2. The method of claim 1, wherein controlling the image projected on the main screen comprises controlling a width to length ratio of each pixel of the image projected on the main screen.

3. The method of claim 1, wherein controlling the image projected on the sub-screen comprises changing a pixel size or ratio based on a point of time at which the image projected on the sub-screen is played back.

4. The method of claim 1, wherein controlling the image projected on the sub-screen comprises changing a pixel size or ratio of an area in the image projected on the sub-screen.

5. The method of claim 4, wherein the pixel size or ratio of the area in the sub-screen is identical with a pixel size or ratio in the main screen.

6. An apparatus for normalizing a size of content in a multi-projection theater, the apparatus 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 comprises

a scale factor operation module configured to compute a scale factor of the image project on the main screen based on the received theater parameters,

a main screen image control module configured to control the image projected on the main screen by incorporating the scale factor into the image, and

a sub-screen image control module configured to control an image projected on a sub-screen so that a height or width of at least any one of images of sub-screens having a different pixel size or ratio from the controlled image of the main screen is identical with a height or width of the controlled image of the main screen.

7. The apparatus of claim 6, wherein the main screen image control module controls a width to length ratio of each pixel of the image projected on the main screen.

8. The apparatus of claim 6, wherein the sub-screen image control module changes a pixel size or ratio based on a point of time at which the image projected on the sub-screen is played back.

9. The apparatus of claim 6, wherein the sub-screen image control module changes a pixel size or ratio of an area in the image projected on the sub-screen.

10. The apparatus of claim 9, wherein the pixel size or ratio of the area in the sub-screen is identical with a pixel size or ratio in the main screen.

11. 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 comprising:

receiving theater parameters stored in a database;

computing a scale factor of an image project on a main screen based on the received theater parameters;

controlling the image projected on the main screen by incorporating the computed scale factor into the image; and

controlling an image projected on a sub-screen so that a height or width of at least any one of images of sub-screens having a different pixel size or ratio from the controlled image of the main screen is identical with a height or width of the controlled image of the main screen.
