## Background
CROSS REFERENCE TO RELATED APPLICATION
The present application claims the benefit of Korean Patent Application No. 10-2013-0152584 filed in the Korean Intellectual Property Office on Dec. 9, 2013, the entire contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a method of representing the visible area of a theater and, more particularly, to a method of representing the visible area of a theater based on the values of angles to a specific spot is seen from a reference spot within the theater.
2. Description of the Related Art
In order to provide audiences with a new three-dimensional effect and immersive experience, a so-called “multi-projection system” different from a known screening system based on a single screen is proposed.
The “multi-projection system” is a technology in which a plurality of projection surfaces is disposed on the periphery of stands (e.g., the front, the left, the right, the ceiling, and the bottom) and an image having a three-dimensional effect and immersive experience can be provided to audiences although a 3D technology is not applied to the image itself.
Such a multi-projection system may be constructed to have a different structure depending on the conditions of a theater because a plurality of projection surfaces is disposed in various directions around stands. More specifically, a plurality of projection surfaces disposed in each theater may have different disposition angles, different areas, etc. depending on the conditions of the theater. Accordingly, the visible area of a theater (i.e., an area where audiences are able to obtain visual information) may be different.
Accordingly, information about the visible area of each theater needs to be taken into consideration in a process of generating the video content of the theater in which such a multi-projection system has been constructed. Furthermore, information about all the visible areas of a theater needs to be taken into consideration in a process of generating “standard image content” that may be played back in all the theaters in each of which the multi-projection system has been constructed.
Accordingly, there is a need for a technology for managing information about the visible area of each theater, but such a technology is not present in a conventional system based on a single projection surface.
Accordingly, there is a need for the development of a technology in which information about the visible area of a theater may be managed and used.
The present invention has been invented based on such a technical background and also has been invented to satisfy the aforementioned technical need and to provide additional technical elements that may not be easily invented by those skilled in the art to which the present invention pertains. Accordingly, the present invention should not be construed as being limited by the technical background.

Accordingly, in other implementations of the present invention, different elements may be used without departing from the spirit and scope of the present invention. Furthermore, each element may be purely formed of a hardware or software element, but may also be implemented using a combination of various hardware and software elements that perform the same function.
Furthermore, an expression that some elements are “included” is an expression of an “open type”, and the expression simply denotes that the corresponding elements are present, but it should not be understood that additional elements are excluded.
Furthermore, terms including ordinal numbers, such as the first and the second, may be used to describe various constituent elements, but the terms are used to only “distinguish” one constituent element from the constituent other element. The attributes of the constituent elements are not limited by the terms.
Furthermore, the method of representing the visible area of a theater to be described hereinafter in accordance with an embodiment of the present invention preferably may be used to represent the visible area of a theater in which a multi-projection system has been constructed, but is not limited thereto. That is, the method of representing the visible area of a theater in accordance with an embodiment of the present invention may be used in a known theater in which a plurality of projection surfaces has not been installed (i.e., a theater including only a single projection surface at the front) and may also be used in a variety of types of theaters including visible areas.
For reference, a “multi-projection system” described in this specification means a screening system including a plurality of projection surfaces. More specifically, the multi-projection system means a system in which a plurality of projection surfaces (e.g., the projection surfaces may be implemented in various forms, such as a screen, the surface of a wall, and the surface of an installation) is disposed on the periphery of stands and a screening environment having a three-dimensional effect and a high immersive experience is provided to audiences by projecting an image on the plurality of projection surfaces.
In this case, the plurality of projection surfaces may be implemented in various forms, such as a screen, the surface of a wall, the bottom, the ceiling, and the surface of an installation). Accordingly, the multi-projection system may be implemented in various forms, for example, 1) a system that uses a screen at the front, the surface of a wall on the left, and the surface of a wall on the right as projection surfaces, 2) a system that uses a screen at the front, the surface of a wall on the left, the surface of a wall on the right, and the surface of the bottom as projection surfaces, and 3) a system that uses the surface of a wall at the front, the surface of a wall on the left, the surface of a wall on the right, the surface of the bottom, and the surface of the ceiling as projection surfaces. In this case, the introduced systems are only illustrative, and the multi-projection system may be implemented in various forms using various projection surfaces.
Furthermore, the method of representing the visible area of a theater to be described hereinafter in accordance with an embodiment of the present invention preferably may be used to integrate and manage pieces of information about the visible areas of a plurality of theaters, but may be used in a process of managing information about the visible area of a single theater.
Furthermore, the “visible area” used in the present invention means an area where audiences may obtain visual information, preferably, an area on which an image is projected within a theater.
Furthermore, the method of representing the visible area of a theater to be described hereinafter in accordance with an embodiment of the present invention may be implemented through a cooperation operation between a variety of types of hardware and software. For example, the method of representing the visible area of a theater in accordance with an embodiment of the present invention may be implemented through the calculation operation of one or more server apparatuses and may be implemented through a cooperation operation between one or more server apparatuses and a variety of types of measurement apparatuses (e.g., sensors and distance measurement apparatuses).
Furthermore, the method of representing the visible area of a theater to be described hereinafter in accordance with an embodiment of the present invention may be programmed and stored in a recording medium that may be recognized by an electronic device.
Hereinafter, the method of representing the visible area of a theater in accordance with an embodiment of the present invention is described with reference to FIGS. 1 to 7.
Referring to FIG. 1, the method of representing the visible area of a theater in accordance with an embodiment of the present invention may include generating the values of angles when a specific spot is seen from a reference spot within a theater at step S11 and representing the visible area of a theater based on the value of the angle at step S12.
At step S11, the values of angles when a specific spot is seen from a reference spot within a theater are generated.
In this case, the reference spot is a reference point, that is, a basis for calculating the values of angles, and may be set in various ways according to a predetermined rule. The reference spot may be set in various ways, for example, as a point in the middle of stands, a point spaced apart from the center of a projection surface, disposed in front of stands, by a specific horizontal distance, a point set based on the structure surface of a theater (e.g., assuming that the distance between the surface of a wall at the front and the surface of a wall at the back is X, the distance between the surface of a wall on the left and the surface of a wall on the right is Y, and the distance between the bottom and the ceiling is Z, a point that is 0.3*X from the front, 0.5*Y from the surface of the wall on the left, and 0.3*Z from the bottom). In such a case, the reference spot preferably may be computed based on the databased structural data of a theater. The reference spot may be set based on input through a user interface and may be set through cooperation with a measurement apparatus for measuring a structure within a theater.
Furthermore, the specific spot means a spot included in a visible area of a theater. The specific spot may be derived based on the databased structural data of a theater or may be derived through cooperation with a measurement apparatus for measuring a structure within a theater. Furthermore, the specific spot may be derived based on input through a user interface.
In an embodiment of the present invention, the value of an angle at which a specific spot is seen from a reference spot may be generated, and the specific spot may be represented. Furthermore, as illustrated in FIGS. 2 to 4, the value of a first angle A when a specific spot is seen from a reference spot in a horizontal direction and the value of a second angle B when a specific spot is seen from the reference spot in a vertical direction may be generated, and the specific spot may be represented. In such a case, the value of the first angle A may be a value belonging to a range of −180 degrees to 180 degrees, and the value of the second angle B may be a value belonging to a range of −90 degrees to 90 degrees. All the visible areas on a three dimension that are formed in a theater may be represented if the values of angles having such a range are used. Furthermore, the value of the first angle A and the value of the second angle B may be calculated using various methods, but preferably may be calculated through operation based on distance information. For example, as illustrated in FIG. 5, the value of the first angle A and the value of the second angle B may be calculated using information about the distance between the reference spot and the specific spot and a second cosine rule. For reference, the distance information may be generated based on the databased structural data of a theater or may be generated based on information generated by a measurement apparatus.
Step S11 preferably may be performed on a plurality of spots included in the visible area of a theater. In such a case, step S11 may be performed on all the spots included in the visible areas, but preferably may be performed on some sampled spots included in the visible area. Furthermore, the sampled spots preferably may be included in the outline of the visible area. If the visible area is visualized through step S12, the entire visible area may be sufficiently represented using only information about the outline of the visible area.
At step S12, the visible area of a theater is represented based on the values of angles generated at step S11. More specifically, at step S12, the visible area of the theater is represented using information about the values of angles when a plurality of spots included in the visible area is seen from a reference spot. In such a case, the visible area may be represented in the form of a visualized graph and preferably may be visualized through a coordinate system using the value of the first angle and the value of the second angle as variables.
FIG. 6 illustrates an example in which the visible area of a theater has been represented through a coordinate system using the value of the first angle and the value of the second angle as variables. In the embodiment of FIG. 6, spots included in the visible area of a theater has been represented as a horizontal angle value (i.e., the value of the first angle A) and a vertical angle value (i.e., the value of the second angle B) with respect to the reference spot. The spots have been visualized on the coordinate system using the value of the first angle and the value of the second angle as variables based on the values of the angles.
As described above, in an embodiment of the present invention, the visible area of a specific theater may become a parameter and may be visualized and represented through step S11 and step S12. In particular, in an embodiment of the present invention, the visible area of a specific theater may be represented through 1) a process of specifying the visible area and sampling and extracting the outer spots of the visible area, 2) a process of generating the values of angles (i.e., the value of the first angle and the value of the second angle) when each of the sampled spots is seen from the reference spot, and 3) a process of visualizing and representing the values of the angles on a coordinate system (i.e., a coordinate system using the value of the first angle and the value of the second angle as variables).
Accordingly, in an embodiment of the present invention, an area within a theater may be divided into a visible area and an invisible area and the visible area and an invisible area may be managed through step S11 and step S12. In this case, as described above, the visible area means an area where audiences are able to obtain visual information and preferably may mean an area on which an image is projected within a theater. Furthermore, the invisible area means an area where audiences are unable to obtain visual information and may include a masking area and an area on which a projector does not perform projection.
Referring to FIG. 1, the method of representing the visible area of a theater in accordance with an embodiment of the present invention may further include representing a standard visible area based on pieces of information about the visible areas of a plurality of theaters at step S13 and generating a standard guide image used to produce standard content based on the information about the standard visible area at step S14.
Steps S11 and S12 correspond to a process of computing information about the visible area of each theater (i.e., computing information about the visible area of a theater 1, the visible area of a theater 2, the visible area of a theater 3, etc. by applying steps S11 and S12 to each of the theaters), whereas steps S13 and S14 correspond to a process of computing pieces of information in all aspects by combining pieces of information about the visible areas of a plurality of theaters.
At step S13, information about a standard visible area is computed by combining pieces of information about the visible areas of a plurality of theaters. In such a case, the pieces of information about the visible areas of the plurality of theaters preferably may be information represented in a coordinate system using the value of the first angle A and the value of the second angle B as variables. The standard visible area may be represented on the coordinate system by combining the pieces of information about the visible areas of the plurality of theaters.
FIG. 7 illustrates an example of a standard visible area generated by combining pieces of information about the visible areas of a plurality of theaters. As seen from FIG. 7, the standard visible area may be divided into three areas. More specifically, the standard visible area may be divided into an area X, an area Y, and an area Z. The area X means an area always not seen in all the theaters (i.e., an area always classified as an invisible area in all the theaters), the area Y means an area seen only in some of all the theaters (i.e., an area classified as a visible area in part of the theater and classified as an invisible area in the remaining theater). Furthermore, the area X means an area always seen in all the theaters (i.e., an area classified as a visible area in all the theaters).
In an embodiment of the present invention, pieces of information about the visible areas of a plurality of theaters may be integrated and managed using information about such a standard visible area. The pieces of information may become parameters and may be managed. Furthermore, since areas defined as visible areas in all of a plurality of theaters can be clearly specified, they may be used in a process of producing standard content that may be applied to all the theaters.
At step S14, a standard guide image used to produce standard content is generated based on information about a standard visible area generated at step S13.
In this case, the standard guide image means an image to which reference is made in a process of converting specific content into standard content. Such a standard guide image may include pieces of correction information for converting specific content (e.g., advertisement content or movie content) into standard content that may be played back in all of a plurality of theaters. Reference may be made to the standard guide image in a process of converting specific content into standard content so that an image can be easily corrected.
In an embodiment of the present invention, the standard guide image may be generated based on the information about the standard visible area. In particular, the size, resolution, data format, etc. of the standard guide image may be specified based on pieces of information about areas defined as visible areas in all of a plurality of theaters. Accordingly, pieces of content converted based on the standard guide image may satisfy the conditions of standard content (i.e., content that may be played back in all the theaters).
As described above, in an embodiment of the present invention, information about a standard visible area that integrates and represents information about the visible areas of a plurality of theaters may be generated through steps S13 and S14. A standard guide image for generating standard content may be generated based on the information about the standard visible area. Accordingly, an embodiment of the present invention may be used in a process of producing standard content that may be played back in a plurality of theaters.
