Abstract

The present invention relates to a method of determining content screening suitabilities in a multi-projection theater including a plurality of projection planes. More particularly, the present invention relates to a method of determining content screening suitabilities based on a series of operation equations using content attribute values, such as the horizontal length and vertical length of an output screen when content is played back, and theater attribute values, such as the length and height of the surface of a front or side wall within a theater building. The method may include calculating at least one of a screen attribute value and a theater attribute value, calculating a suitability based on the screen attribute value or the theater attribute value, and determining whether the calculated suitability falls within a predetermined range.

Claims

1. A method for determining content screening suitabilities in a multi-projection theater, the method comprising:

calculating at least one of a screen attribute value and a theater attribute value;

calculating a suitability based on the screen attribute value or the theater attribute value; and

determining whether the calculated suitability falls within predetermined ranges,

wherein the screen attribute value is a value representing either length or area related to a content output screen, and the theater attribute value is a value representing either length or area related to a projection surface within the theater, or a number of seats in the theater,

wherein the calculated suitability is a ratio obtained using the screen attribute value or the theater attribute value, and

wherein a content is screened in the multi-projection theater based on the determination that the calculated suitability falls within the predetermined ranges.

2. The method of claim 1, wherein:

said calculating at least one of the screen attribute value and the theater attribute value comprises calculating a plurality of the screen attribute values and a plurality of the theater attribute values,

said calculating the suitability comprises calculating suitabilities based on the plurality of screen attribute values and the plurality of theater attribute values, and

said determining whether the calculated suitability falls within the predetermined ranges comprises determining whether content is suitable for being screened according to each of the suitabilities by determining whether each of the suitabilities falls within a predetermined range among the predetermined ranges.

3. The method of claim 1, wherein determining whether the calculated suitability falls within the predetermined ranges comprises

assigning a class corresponding to a predetermined range to the calculated suitability when the calculated suitability is determined to fall within the predetermined range among the predetermined ranges.

4. The method of claim 1, wherein:

the screen attribute value comprises a width of a content output screen,

the theater attribute value comprises a width of a projection surface within the theater, and

the calculated suitability comprises an effective area ratio calculated by Equation (1) as follows;

5. The method of claim 4, wherein the calculated suitability is determined to be satisfied if the effective area ratio is 0.7 or more to 1.0 or less.

6. The method of claim 1, wherein:

the screen attribute value comprises a front traverse length and side traverse length of a content output screen, and

the calculated suitability comprises a front side ratio (FSR) calculated by Equation (2) as follows;

7. The method of claim 6, wherein the calculated suitability is determined to be satisfied if the FSR is 1.75 or more to 2.25 or less.

8. The method of claim 1, wherein:

the screen attribute value comprises a traverse length of a content output screen,

the theater attribute value comprises a traverse length of a projection plane within the theater, and

the calculated suitability comprises a front offset ratio (FOR) calculated by Equation (3) as follows;

9. The method of claim 8, wherein the calculated suitability is determined to be satisfied if the front offset ratio is 1.0 or more to 1.2 or less.

10. The method of claim 1, wherein:

the theater attribute value comprises a left bezel and a right bezel, and

the calculated suitability comprises a front symmetric ratio calculated by Equation (4) as follows;

11. The method of claim 1, wherein:

the theater attribute value comprises a number σ and

a total number N of seats disposed in a height lower or higher than an image output range, and

the calculated suitability comprises an effective seat ratio calculated by Equation (5) as follows;

12. The method of claim 1, wherein:

the theater attribute value comprises an area of one or more protrusions on a projection plane and an effective area of a projection plane on which a content image is projected, and

the suitability comprises a distortion area ratio calculated by Equation (6) as follows;

13. An apparatus for determining content screening suitabilities in a multi-projection theater, comprising:

a control unit configured to

calculate at least one of a screen attribute value and a theater attribute value,

calculate a screening suitability of a content based on at least one of the screen attribute value and the theater attribute value, and

determine whether the calculated screening suitability falls within a predetermined range,

wherein the screen attribute value is a value representing either length or area related to a content output screen, and the theater attribute value is a value representing either length or area related to a projection surface within the theater, or a number of seats in the theater,

wherein the calculated screening suitability is a ratio obtained using the screen attribute value or the theater attribute value, and

wherein the content is screened in the multi-projection theater based on the determination that the calculated screening suitability falls within the predetermined range.
