Description

TECHNICAL FIELD [0001] The present invention relates to a variable interactive digital stage image system,

The present invention relates to a variable interactive digital stage image system that can be freely changed and used according to various stage environments by preliminarily adjusting and synthesizing a background image and a facility image that are separately manufactured according to the location and size of a facility installed in a theater, ≪ / RTI >

In general, a plurality of facilities constituting an environment of a stage are installed in a performance hall, and various performances are performed by applying a facade technique of projecting a digital image using a projector according to the shape of an outer wall of the facility.

However, conventionally, since a digital image is produced in accordance with a scale of a stage to be a standard, it is very difficult to match an image already produced in a venue having a different size or size.

Therefore, it was troublesome to reproduce the stage video (digital image) in accordance with the changed stage every time according to the environment of the performance hall.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a background image and a facility image which are separately prepared according to the location and size of a facility installed in a theater, And an object of the present invention is to provide a possible interactive interactive digital stage video system and a production technique.

The variable interactive digital stage video system according to the present invention divides an image of a stage used as a venue into a background image for a background screen and a facility image for a facility screen, The background image and the facility image are adjusted in advance and synthesized and projected onto the facility.

The variable interactive digital stage video system according to the present invention has an effect of producing a video image suited to the size and position of various facilities installed on the stage by separating and producing the background image and the facility image.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, a variable-type interactive digital stage video system is produced by separating a performance background image and a facility image, which are to be produced each time according to the size and environment of a theater, into a digital image and reproducing the digital image according to a performance environment It is a suggestion of a technology that can be used.

In particular, the image of the facility image is produced as a high-resolution image when the performance is not changed during the performance and as a moving image having the alpha channel when the performance is changed during the performance. The basic concept is to synthesize and output the background image and the facility image.

In the present invention, a stage image used as a theater is divided into a background image for a background screen and a facility image for a facility screen, and then a background image and a facility image are displayed in advance according to the location and size of a facility installed in the hall And synthesized and projected onto the facility.

When a stage image of a performance hall is produced, as shown in FIG. 1, a plurality of stage devices such as a facility 1 (1), a facility (2), and a facility (3) are located on the stage rear part.

If the stage size or scale changes, the stage equipment, such as the wall installed for image projection, must also be changed, and the image must be changed to match the scale.

However, since an actor performs a performance on the front of the stage apparatus, the size and the image of the stage apparatus should never be changed, and the size of the image to be designated according to the flow of the pole exists.

Therefore, in the present invention, a background image and a facility image are separately produced when the image is produced, and a technique of merge and project two images in real time is proposed.

Accordingly, in the present invention, the background image and the facility image are projected on the image output device to the facilities 1 (1), 2 (2), and 3 (3) by various combinations of the background image and the facility image prepared in advance, It becomes possible to express the facilities 1a, 2a, 3a, 1b, 2b and 3b which can be used.

In addition, the present invention can be applied to [stage image produced as a reference] (upper figure) as shown in Fig. 2 [the stage image where the facility image is enlarged and the background image is scaled] Fitting can be done.

This is a very important factor when considering that the actor is exposed to the audience in comparison with the size of the facility image in the performance hall.

At this time, if the 'facility image' of FIG. 3A and the 'background image' of FIG. 3B are combined, the final completed 'composite original image' of FIG. 3C is created.

Since the 'background image' is an image that targets all the venues, it is designed so that a software operation for enlarging / reducing the venue in accordance with the size of the venue can be performed. The 'facility image' is generated according to the location of a facility And to make the software operation for reduction / enlargement of the size possible.

In addition, the 'facility image' is configured to have an alpha channel for transparency processing in areas other than the facility so as to be easily combined with the 'background image'.

The alpha channel means a special channel for masking or controlling a specific area of an image.

A typical screen is composed of three channels, and three images of R (red), G (green) and B (blue) are synthesized to form an image. These three channels and the fourth channel are referred to as alpha channels, and they are synthesized with other images in black and white. For example, assume that the image of the alpha channel is A and the screen to be composited is B. The white part of the alpha channel of the A screen has the image of A, the black part becomes transparent, .

Therefore, in the case of a narrow theater, 'synthetic original image' may be used as it is, as shown in FIG. 4A, and used as a 'synthetic altered image' as shown in FIG. 4B . In this case, since the 'facility image' is divided into object units so as to be divided into a plurality of facilities and can be projected and moved, as shown in FIG. 5, the three objects centered on the center may be arranged in a left- have.

Meanwhile, as shown in FIG. 6, the method of fabricating the variable interactive digital stage image system according to the present invention is completed according to the following steps.

First, in the background image preparation step (S10), a background image for decorating the back side of the stage is created using computer graphic technology. At this time, a performance setting setting step S11 for specifying a layout of a performance hall suitable for the background image is preceded or followed.

Then, in the background image preprocessing step S12, the size and the ratio of the background image are adjusted through image processing to adjust the sizes of the video output device and the venue. This can be simply implemented by the image processing technique that has been conventionally introduced, and therefore, a detailed description thereof will be omitted. The background image pre-processing (S12) is the same as the operation for reproducing the currently used performance image.

If a hardware mixer device is used after the background image preprocessing step S21, an alpha channel is added to the image for transparent processing of the image to be synthesized. If a software mixer is used, The transparency processing step S13 may be added to the transparency processing step.

In addition, in the facility image preparation step S20, a specific shape overlapping the entire background image is created using computer graphics technology. At this time, a location determination step (S21) for confirming the location of the facility suitable for the facility image is preceded or followed.

Then, in the facility image preprocessing step S22, the process of moving the position of the facility image projected on the facility installed in the performance site to a specific position of the background image is performed. The facility image preprocessing (S22) can be implemented in software in a program for conventional image processing.

After the facility image preprocessing step S21, a reduction / enlargement step S23 for adjusting the size of the object image according to facilities through image processing may be added.

Finally, an image output step S40 for sequentially outputting the synthesized image to the outside through an image synthesizing step S30 for synthesizing the adjusted background image and the facility image is sequentially performed.

In the present invention, the created background image, the facility image, and the background image are reproduced simultaneously on the same screen through a mixer device, thereby constructing an environment in which one performance image is reproduced. The mixer device A hardware device for image synthesis may be used or software may be implemented.

In the case of image synthesis, a mixer device for synthesizing two images can be used. In case of using a hardware mixer device, an alpha channel should be added to the image for transparent processing of the synthesized image, and a software mixer It is possible to perform operations such as transparency processing and reduction and enlargement in parallel with the preliminary processing of the facility image.

In the case of a software mixer, an overlay mixer technique used for processing subtitles or the like, or a mixer bitmap (mixer renderer) used at the time of reproduction, Can be set to play

Therefore, even if the performance environment is changed due to the change of the performance site, the background image and the facility image that have been produced in the past can be processed through the same process, so that the image suitable for each performance site can be reproduced without creating a new performance image for each venue.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. will be.
