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.

First claim

What is claimed is:

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 a predetermined range.

2 . The method of claim 1 , wherein:
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, calculating the suitability comprises calculating one or suitabilities based on the plurality of screen attribute values and the plurality of theater attribute values, and determining whether the calculated suitability falls within the predetermined range 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.

3 . The method of claim 1 , wherein determining whether the calculated suitability falls within the predetermined range comprises assigning a class corresponding to a predetermined range to a suitability if, as a result of the determination, each of the suitabilities is determined to fall within any one of a plurality of 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 suitability comprises an effective area ratio calculated by Equation 1.

5 . The method of claim 4 , wherein the content screening 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 suitability comprises a front side ratio (FSR) calculated by Equation 2.

7 . The method of claim 6 , wherein the content screening 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 suitability comprises a front offset ratio (FOR) calculated by Equation 3.
