Description

{METHOD OF PRODUCING AND IMPLEMENTING FOR DYNAMIC CINEMA}

The present invention relates to digital cinema technology, and more particularly to digital cinema production, data processing, screening methods, and the like.

Today, cinema is produced and displayed by digital technology. Digital cinema technology has been developed by various video technologies, sound technologies, and DRM technologies. To understand digital cinema technology in a basic and simple way, it is possible to distinguish between a portion where an image is captured by a digital camera and a portion where a digital image is displayed in a theater by a projector. And these two parts are very closely related.

The view angle of a viewer in a movie theater for a digital cinema photographed by a digital camera of a conventional 2K standard (2048 pixels wide, 1080 pixels high) was about 30 to 60 degrees. The image is reproduced on the screen via the projector. Since the size of the screen must correspond to the 2K standard, there is a limit to enlarging the view angle of the spectator.

In addition, according to the related art, since the size of the screen is standardized so as to meet the aspect ratio of the digital image produced by the standard, there is no room for attempting movie grammar implementing dynamic cinema. An image file produced by conventional digital cinema technology will almost fill the screen's screen. As part of an attempt to implement dynamic cinema, 3D imaging technology has become known. However, 3D video technology has to be shot using two cameras and there are complicated technical disadvantages of using complex editing techniques. Moreover, the size of the screen could not be exceeded, only to express the stereoscopic effect using special equipment. Theoretically, you could use more cameras to extend the image's width. However, in reality, it is necessary to use more complicated shooting techniques, which causes a rise in the production cost, while it may reduce the completeness of the work and hinder the viewer's viewing environment.

Setting multiple camera values at the same time, adjusting focus, and matching geometry requires not only sophistication but also empirical trial and error. These technical difficulties are perceived as a risk factor for filmmakers and cause the production period and costs to rise. This is evidenced by the fact that the production of live-action films that are actually shot in 3D is scarcely increased, while the cases of converting 2D movies into 3D are continuously increasing. In the end, it tells us that even in the case of a special type of film, it is difficult to increase the technical difficulty in shooting.

The inventors of the present invention have made efforts to research for a long time in accordance with the user demand as described above, and thus the present invention has been completed.

An object of the present invention is to provide a novel digital cinema production technique which is easy to manufacture and has a wide viewing angle. The inventors of the present invention recognize that even if a new manufacturing technique is used, it is difficult to apply it to a scene where a movie is shot if the photographing equipment is changed as compared with a conventional photographing technique. Therefore, we concluded that the approach of shooting simultaneously with multiple cameras, like 3D technology, is both uneconomical and impractical. It is therefore an object of the present invention to be based on the premise that it does not cause any special change in the conventional field shooting technique.

It is another object of the present invention to provide a dynamic cinema implementation method capable of dynamically moving a screen on a screen when a movie is displayed. The screen of the digital cinema produced by the present invention can be varied in its width and can be moved to the left or right side and can be dynamically executed such as division and enlargement of the screen to ensure various image representations of production supervision will be.

On the other hand, other unspecified purposes of the present invention will be further considered within the scope of the following detailed description and easily deduced from the effects thereof.

(b) cutting the upper and lower parts of the image file of the original file according to a predetermined effective range; And

and (c) splitting the frames constituting the edited image of step (b) performed by the editing computer in the left and right halves to store the left channel image file and the right channel image file, respectively .

Further, in the dynamic cinema production method according to the preferred embodiment of the present invention, the camera apparatus preferably has a monitor on which a guide box corresponding to the predetermined effective range is displayed.

In the dynamic cinema production method according to the preferred embodiment of the present invention, when the resolution specification of the image file in step (a) is ^{2n +} 1K (n is a natural number) The resolution of the left channel image and the right channel image is preferably 2 ⁿ K resolution.

The present invention can provide a new movie format (panoramic digital cinema). Profitability of 3D movies is reported to be superior to 2D movies. Because the audience is spending the equivalent of a better visual experience. This gives producers an opportunity to earn higher returns. However, in 3D movies, the production cost has increased, and the opportunity cost is very large depending on whether or not it is in the market. On the other hand, panoramic digital cinema is expected to be relatively economical because the cost of production is the same as that of 2D movie, but the view angle of viewers is large and the dynamic implementation of the screen is possible. The new method proposed by the present invention thereby makes it attractive to the producers.

In addition, the present invention is capable of achieving a remarkable effect capable of realizing dynamic cinema. According to the present invention, it is possible to dynamically move the size of a screen when a video is projected on a screen, and a technical environment for various editing is provided. It is possible to enlarge, reduce, move to the left, move to the right, and so on. This allows us to provide new and creative film grammar technically.

* The accompanying drawings illustrate examples of the present invention in order to facilitate understanding of the technical idea of the present invention, and thus the scope of the present invention is not limited thereto.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

Figure 1 schematically shows the overall process of the dynamic cinema method of the present invention. First, the digital camera device acquires an image file while shooting an object (S100). A plurality of camera apparatuses will be used in the field where the movie is shot, but in the present invention, two camera apparatuses form a group, as in the case of obtaining a 3D image, and do not shoot images. The camera devices will acquire the image file independently of each other, and the image file to be displayed during the editing process will be determined.

Next, the editing computer in which the image editing software is installed cuts the upper and lower parts of the original image file according to the predetermined effective range (S110).

It is important in practice for a camera operator to know which part of the screen is cut during the editing process when shooting a movie. Preferably, the guide box is displayed on the monitor screen of the camera apparatus. 2, an image 70a corresponding to the object 70 is displayed on the monitor screen 10 of the camera device when the camera device is photographing the object 70. [ At this time, the portions (40, 50) and the remaining portions (30) which are cut according to the technical idea of the present invention are displayed together on the monitor screen (10). That is, in the preferred embodiment of the present invention, the guide box 20 can be configured to display the monitor screen of the camera device. By doing so, it is ensured that the photographer at the time of photographing is able to correspond to the "image screen predicted to be screened" and the image screen in which the cutting process in step S110 is performed during the editing process. As a specific method, in some embodiments, the guide box 20 can be automatically displayed on the monitor screen by the interface software installed in the camera device. Also, in a preferred alternative embodiment, a guide box 20 may be displayed by drawing lines on the monitor screen. As a result, in order to implement the method of the present invention, it is necessary to replace the conventional camera device or to avoid the technical disadvantage of shooting the image differently from the conventional method.

The meaning of the predetermined effective range in step S110 needs to be explained in more detail.

For digital cinema standards, technical standards are applied. For example, a digital cinema defined by the Digital Cinema Initiatives (DCI) standard or the SMPTE standard has a flat (width: 1998) aspect ratio of 1.85: 1 within 2K (2048 pixels wide by 1080 pixels high) Pixels, height 1080 pixels) and 2.39: 1 scope (width 2048 pixels, height 858 pixels). In 4K (width 4096 pixels, height 2160 pixels) resolution, the aspect ratios are doubled and the aspect ratios are the same.

3 (a) illustrates an image screen 100 taken by a 4K camera. The upper portion 100a and the lower portion 100b are discarded by cutting the image along the upper and lower lines of the guide box 20 shown in FIG. As shown in Fig. This is like having a 2K camera shot, but doubles the width. This means that it can maintain compatibility with the existing 2K digital cinema standard. In the present specification, a movie whose width is twice as large as a screen photographed by the conventional movie technique is defined as " Panoramic Digital Cinema ". That is, in the panoramic digital cinema, the image screen 101 edited as in 3 (b) is twice as long as the conventional image screen (panoramic digital cinema image in the 2K flat standard).

Currently, the equipment used in the shooting scene is a 2K camera, sometimes using a 4K resolution camera, but it is possible to shoot a movie using an 8K camera in the future. Likewise, the 16K and 32K standards can be used. For example, when the resolution specification of the original image file is 2 ^{n + 1} K (n is a natural number) resolution, a panoramic digital movie image file having a resolution of 2 ⁿ K can be obtained.

After cutting the image screen of the original file into upper and lower portions, the editing computer splits the frames constituting the edited image into half (S120). FIGS. 4 and 5 illustrate the concept of step S120 as a flat standard and a scope standard, respectively. All the still image frames constituting the edited video are separated in half. As a result, the unit edit image is separated into the left image and the right image. In the flat standard, as shown in FIG. 4, the scope standard is the same as FIG. 5, but there is no difference in that the images are divided into the left image and the right image by being separated in half.

The operation of step S120 is executed for all image frames. When the edited image file is stored, the editing computer stores the left images as a left channel image file in the memory, and the right images are stored in the memory as a right channel image file (S130). In step S130, two final edited image files are obtained. Steps S100 to S130 in FIG. 1 are the dynamic cinema production methods. The execution method of implementing the dynamic cinema will be completed by executing step S140.

Two final video files will be played at the Cinema Theater. The Cinema Theater is equipped with two projectors connected to a DCP (Digital Cinema Package) server. General DCP servers may not clearly distinguish and recognize the DCP of the panoramic digital cinema of the present invention. Preferably, indexing of the image file can be performed for this purpose. As described above, through the steps S120 and S130, the left part of the panoramic digital cinema image of the present invention is stored in the left eye of the 3D movie, and the right part of the panoramic digital cinema image is separately stored in correspondence with the right eye of the 3D movie You can. In other words, the author can master the movie by designating the movie in 3D format during the mastering process of generating the DCP. However, it is possible to insert a specific character string representing the panoramic digital cinema into the Annotation Text item of the CPL (Composition Play List) information of the DCP. For example, if there is a string such as "#panorama" in the Annotation Text, the DCP server of the panorama digital cinema can recognize the image files in the panorama digital cinema format. In another embodiment of the present invention, a cover for identifying the panoramic digital cinema may be inserted into the Kind item indicating the type of the image. However, if you want to avoid interference and collision with DCP servers that do not support the panorama feature, it is more efficient to use Annotation Text as described above. Of course, it would be possible to create a new xml tag that would identify the panoramic digital cinema, or make the new format a technical standard.

The two projects are installed on the left and right sides of the upper rear side of the auditorium. The two projects 500 and 501 simultaneously output the left channel image file and the right channel image file, respectively, as shown in FIG. 6, and project them on the screen (S140). Step S140 is executed by the panorama digital cinema server, and two projectors output images in a dual-stream format. When the current DCP servers output 3D images, the images are output to the screen in a sequential format (sequential). However, the panoramic digital cinema server of the present invention must be capable of simultaneously outputting the left and right images do.

The left projector 500 projects the left image to the left image screen 1001 of the screen 1000 and at the same time the right projector 500 projects the right image to the right image screen 1002 of the screen 1000 do. As a result, it is possible to display a movie through the screen 1002 having a very large left and right length. As a result, the viewing angle of the movie can be greatly extended to 60 to 120 degrees according to the position of the viewer 1.

Also, as shown in the center portion of the screen of Fig. 6, an edge blending area 1005 of the left image and the right image can be configured. It is a technique to eliminate the vertical line which distinguishes the left image and the right image. For this purpose, the edge blending technique can be used in the decoding process of creating the left image and the right image. This is as shown in FIG. The embodiment of FIG. 7 is described based on the 2K flat standard.

The present invention obtains the left image 111 and the right image 112 separated (or separately stored) in step S120 (or step S130). The left part 112a of the right image 112 is combined with the right part of the left image 111 to obtain the extended left image 111x. In the case of the right image, the right part 111a of the left image 111 is combined with the left part of the right image 112 to obtain the extended right image 112x. Preferably 20 pixels as the edge blending area, the size of the image frame can be constantly extended. And an extended portion on the opposite side of the joint portion, thereby forming a final left image 111y and a final right image 112y. This image is configured to be respectively projected through the projectors of the auditorium. In this manner, the left and right screens can be partially overlapped on the central portion of the screen, so that seams for distinguishing the left and right images are not displayed.

The auditorium does not display only the panoramic digital cinema image of the present invention, but may display a conventional 2K DCP, for example. Even in this case, the two projectors 500 and 501 can be used. In this case, the 2D blending technique can be applied to the left and right images by dividing the 2D image of the general digital cinema by the same method as described above . With this configuration, the panorama digital cinema server can maintain full compatibility with the normal 2K DCP.

Figures 8 and 9 illustrate in more specific scenarios how dynamic cinema can be implemented in the present invention.

As shown in Fig. 8, the panoramic digital cinema image will be projected entirely on the screen by the two projectors. However, as described above, the area 200 in which the image is projected is not a state in which the horizontal length is twice as long as that of the conventional 2K screen as in the panoramic digital cinema, but is only one half of the image length of the panoramic digital cinema. That is, it is substantially the same as projecting by conventional photographic techniques. From the viewpoint of the panoramic digital cinema technology of the present invention, the screen is smaller, and the movie can be displayed only in the central portion of the screen. The left image 201 is composed of a video data area 201a and a blank area not including image data and similarly the right image 202 is divided into a video data area 202a and a video data area 202a, Which is an empty space that does not include a blank area, and then the images can be simultaneously projected by the two projectors. The configurations of the video data areas 201a and 202a and the blank areas 201b and 202b can be edited using an editing computer.

In the embodiment of FIG. 8, only about half of the entire length of the panoramic digital cinema of the present invention is displayed on the screen. However, the length of the image is not limited to the image data area constituting the image file of the left channel and the image file of the right channel, And can be variously determined by the editing ratio of the area.

On the other hand, when the blank area 201b of the left image 201 is 0%, the image data area 201a is 100%, the blank area 202b of the right image 202 is 100%, and the image data area 202a is 0%, it is possible to make the image displayed as 9 (a) be positioned on the left side. Conversely, when the blank area 201b of the left image 201 is 100%, the image data area 201a is 0%, the blank area 202b of the right image 202 is 0% When the area 202a is 100%, the image displayed as shown in 9 (b) can be positioned on the right side only.

When the blank area 201b of the left image 201 is 0%, the image data area 201a is 100%, the blank area 202b of the right image 202 is 50%, and the image data area 202a) is 50%, the entire left image is projected through the left projector to occupy the left portion of the screen as shown in 9 (c), and the right image can be displayed through only the portion of the screen through the right projector have. The opposite case is shown in Fig. 9 (d).

When the editing computer divides the image into two halves through steps S120, the operation is performed for each unit image frame. At this time, by editing the ratio of the image data area and the blank area constituting the left and right images so as to change constantly for each frame, it is possible to dynamically move the size of the screen when the image is projected on the screen. As a result, a technical environment capable of various editing including the above-mentioned contents can be created. It is possible to enlarge, reduce, move to the left, move to the right, and so on. This allows us to provide new and creative film grammar technically.

The scope of protection of the present invention is not limited to the description and the expression of the embodiments explicitly described in the foregoing. It is again to be understood that the present invention is not limited by the modifications or substitutions that are obvious to those skilled in the art.
