Description

[0001] The present invention relates to a screen baseball system using multiple displays,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen baseball system, and more particularly, to a screen baseball system for enhancing realism and interest to a user by applying a multiple display scheme.

A "screen baseball" means a baseball game similar to a real baseball game, in which the user views the projected image using a device such as a screen on which the image is projected and a pitching machine or a toaster machine.

Among them, a "batting mode" in which a baseball game is played according to a standard baseball game rule while the result is calculated, and the process is repeated when the user hits the ball ejected from the pitching machine as a batter, to be.

Specifically, a screen hole exists in a screen where an image is projected. When a ball is ejected from a pitching machine located on the opposite side of the screen, the user hits the ball toward the screen, and various sensors sense the velocity and direction of the hit ball And calculates the batting result.

In addition, a "pitching mode" in which the game progresses as a pitcher is also possible.

In the pitch mode, the user who receives the ball from the toss machine paces toward the screen on which the image is projected, and calculates the scratch / ball state according to the position on the screen where the ball has reached.

The user can enjoy the pitch mode of the screen baseball game as a kind of score game or enjoy the 3-inning, 6-inning or 9-inning game according to the actual baseball game rules.

In other words, screen baseball aims to simulate a real baseball game to give the user a sense of enjoyment and enjoyment of a real baseball game. For this purpose, it is important to give the user a feeling of being in a real baseball game.

For this purpose, the screen baseball stadium uses a sound device, a video device, or the like to give the user a feeling of climbing onto a batting seat or a mound of a real baseball stadium. In the case of a sound effect, it is difficult to implement because of limitation of a screen provided in a two-dimensional plane form in the case of a picture effect.

Referring to FIG. 1, according to a conventional screen baseball system using a single display method, an image projected from one image unit 200 is projected onto one screen 100. FIG.

In this case, since the screen 100 is generally provided in the form of a two-dimensional plane, the image is projected only in the central portion of the screen 100 when the user looks at it, and the image is not projected on the left and right sides, .

Accordingly, in order to improve the immersion feeling, a method of extending the image projected from the image portion 200 to the left and right sides and outputting it to the screen 100 has been proposed (see FIG. 3).

According to this method, since the first side screen 120 and the second side screen 130 extend in the direction toward the user, the size of the image output from the first side screen 120 and the second side screen 130 increases in the direction toward the user, May be reduced.

When the data processor 300 receives a single source image information, the source image information includes all the image information to be output from the center screen 110, the first side screen 120, and the second side screen 130 Can be interpreted as doing.

Therefore, the data processor 300 does not process the image information to be outputted to the central screen 110 among the single source image information, for separate distortion.

On the other hand, the image information to be outputted from the first side screen 120 and the second side screen 130 is processed as separate corrected image information by processing.

When a part of the source image information is generated as corrected image information through a process for distortion, the data processor 300 considers the type of the image part 200 to which the corrected image information is to be projected.

When the image information is projected only in the central image part 210, the data processor 300 delivers the corrected image information to the central image part 210 without performing an image segmentation process.

When the image information is projected on both the central image portion 210, the first side image portion 220, and the second side image portion 230, the data processor 300 outputs the image information 220 and 230 by dividing the image information to be projected from the central image part 210 and the image information to be projected from each of the side image parts 220 and 230.

More specifically, the image information to be projected from the central image part 210 is source image information, and the image information to be projected from each of the side image parts 220 and 230 is corrected image information.

The source image information transmitted to the central image unit 210 is projected to the center screen 110 and the corrected image information transmitted to the respective side image units 220 and 230 is projected to the respective side screens 120 and 130, respectively.

Meanwhile, as described above, the central image unit 210 can project image information to be outputted from the upper screen 140 and the lower screen 150. The data processor 300 determines whether or not the data is corrected according to the type of the image information to be projected on the upper screen 140 and the lower screen 150.

Specifically, when certain image information such as sky or grass is outputted considering the upper and lower sides of the image information to be outputted from the center screen 110, the first side screen 120 and the second side screen 130, The source image information is directly output without a process for distortion of the image.

On the other hand, when continuous image information is to be output on the upper and lower sides of the image information to be outputted from the center screen 110, the first side screen 120, and the second side screen 130 such as the electric sign board and the mound, And then generated as corrected image information.

The generated image information is transmitted to the central image portion 210, the first side image portion 220 and the second side image portion 230 to be projected on the upper screen 140 and the lower screen 150, As shown above.

It is needless to say that the processing sequence for image distortion and the sequence of the image segmentation process described above can be changed.

2) Description when a plurality of source image information is inputted

When the data processor 300 receives a plurality of source image information, the source image information is image information to be output from the center screen 110, the first side screen 120, and the second side screen 130, respectively Can be interpreted.

First, the data processor 300 does not process the image information to be outputted from the center screen 110 among the plurality of source image information, for the purpose of distortion.

On the other hand, the image information to be outputted from the first side screen 120 and the second side screen 120 is processed as separate corrected image information through processing for distortion.

When a part of the source image information is generated as corrected image information through a process for distortion, the data processor 300 considers the type of the image part 200 to which the corrected image information is to be projected.

When corrected image information is output only from the central image portion 210, the data processor 300 merges the source image information and the corrected image information. That is, the source image information to be outputted to the center screen 110 and the corrected image information to be outputted from each of the side screens 120 and 130 are synthesized.

The synthesized corrected image information is projected from the central image part 210 and output from the center screen 110 and the respective side screens 120 and 130.

 When the correction image information is output from the central image portion 210, the first side image portion 220 and the second side image portion 230, the data processor 300 outputs the corrected image information to the central image portion 210, The source image information to be projected and the image information to be projected from the side image units 220 and 230 are transmitted to the image units 210, 220 and 230, respectively.

Specifically, the image information to be projected from the central image part 210 is source image information, and the image information to be projected from each of the side image parts 220 and 230 is the corrected image information as described above.

The source image information transmitted to the central image unit 210 is projected to the center screen 110 and the corrected image information transmitted to the respective side image units 220 and 230 is projected to the respective side screens 120 and 130, respectively.

Meanwhile, as described above, the central image unit 210 can project image information to be outputted from the upper screen 140 and the lower screen 150. The data processor 300 determines whether the image information is to be projected on the upper screen 140 and the lower screen 150 among the plurality of input source image information and whether the image information is to be projected, 230).

The source image information or the corrected image information is then transmitted to the central image portion 210, the first side image portion 220 and the second side image portion 230 to be projected onto the upper screen 140 and the lower screen 150, Is the same as when the data processor 300 receives a single source image information.

In another embodiment, the source image information received by the data processor 300 may be divided into left, right, center, upper and lower sides, respectively.

3. Description of the process of projecting image information on the screen 100

In the screen baseball system according to the embodiment of the present invention, the multi-display system is used to enhance the sense of reality, thereby improving the user's interest and immersion.

Hereinafter, the process of projecting the image information projected on the screen 100 to the screen 100 through the processing for distortion and outputting the image information from the image unit 200 will be described in detail with reference to FIGS. 5 to 9. FIG.

(1) Explanation of distortion process for generating corrected image information

Referring to FIGS. 5 and 6, a process in which the data processor 300 distorts image information projected from the first side image portion 220 and the second side image portion 230 is illustrated. Hereinafter, a process of generating corrected image information based on the position of the central image 210 will be described in detail.

As described above, the central image portion 210 is positioned on a line M extending from the center of the center of the center screen 110 in the horizontal direction.

The distance from the central image portion 210 to the edge of the first side screen 120 or the second side screen 130 that contacts one side of the center screen 110 is A and the distance from the center image portion 210 to the first The distance to any point on the side screen 120 or the second side screen 130 is x.

At this time, the size of the pixel at any point of the corrected image information output on the first side screen 120 or the second side screen 130 is determined by the size of the pixel at the point corresponding to the corresponding point of the source image information And the size is multiplied by a predetermined ratio.

Specifically, the size of the pixel at a certain point in the corrected image information can be obtained by multiplying the size of the pixel at a point corresponding to the corresponding point of the source image information by the square of the ratio of x and A.

This is due to the proportional formula using the trigonometric function, since the area of the two-dimensional plane is adjusted in proportion to the distance.

 Accordingly, by applying this process to all of the points on the first side screen 120 or the second side screen 130, corrected image information output to the first side screen 120 or the second side screen 130 is generated .

6 (a) is the size of the pixel SP at each point of the source image information, and FIG. 6 (b) is the size of the pixel DP at each point of the corrected image information. And the corrected image information is projected on the first side screen 120. As shown in FIG.

The corrected image information in which the size of the pixel DP at each point of the corrected image information is reduced from one side adjacent to the center screen 110 of the first side screen 120 to the opposite side from the other side is projected through the above- .

The process of generating the corrected image information and the resultant result may be similarly applied to the second side screen 130. In this case, the corrected image information in which the size of the pixel D.P at each point of the corrected image information decreases from one side adjacent to the center screen 110 of the second side screen 130 to the other side opposite to the center side 110 will be projected.

Accordingly, as the distance between the first side screen 120 and the second side screen 130 is shortened, the angle of the corrected image information projected on each of the side screens 120 and 130, The size of the pixel DP at the point can be reduced to prevent or reduce the distortion phenomenon, thereby increasing the sense of presence.

In addition, the above-described process can be utilized to generate corrected image information to be output to the upper screen 140 and the lower screen 150. [

(2) Explanation of an image projection process using a single number of image units 200

Referring to FIG. 7, the image portions 200 are provided in a single number so that images output to the screen 100 are projected only from the central image portion 210 (see (B1) and (C1) of FIG. 4).

The data processor 300 generates corrected image information using the source image information through the above-described process, and then transmits the source image information and the corrected image information to the central image portion 210.

The central image unit 210 projects the received source image information and corrected image information to the screen 100. [ Specifically, the source image information is projected on the center screen 110, and the corrected image information is projected on the first side screen 120 and the second side screen 130, respectively.

The image information may be output to the upper screen 140 and the lower screen 150 through the same process as described above.

(3) Explanation of an image projection process using a plurality of image portions 200

8, the image unit 200 includes a plurality of images, that is, a central image unit 210, a first side image unit 220, and a second side image unit 230, (See (B2) and (C2) in FIG. 4).

The data processor 300 generates corrected image information using the source image information through the above-described process, and then transmits the image information to the image unit 200. Specifically, the source image information is transmitted to the central image portion 210, and the corrected image information is transmitted to the first side image portion 220 and the second side image portion 230, respectively.

Each of the image units 210, 220, and 230 projects the received source image information and corrected image information to the screen 100. The first side image 220 and the second side image 230 may include the corrected image information on the first side screen 120 and the first side image 120. [ And the second side screen 230, respectively.

The image information may be output to the upper screen 140 and the lower screen 150 through the same process as described above.

(4) Description of the case where the screen 100 is provided in a circular shape or an oval shape

In another embodiment, the screen 100 may be provided in a circular or oval shape. In this case, it is preferable that the center screen 110, the side screens 120 and 130, the upper screen 140, and the lower screen 150 are provided as a single number without discrimination.

In this case, the data processor 300 can not use the proportional formula according to the trigonometric function to generate corrected image information. It is not only the distance between each pixel and the user but also the curvature of the screen 100 itself.

Accordingly, the data processor 300 generates the corrected image information using the curvature equation rather than the trigonometric function, and can further use the proportional formula according to the trigonometric function to improve the accuracy thereof.

The process of projecting the generated corrected image information on the screen 100 is as described above. In addition, the image information may be projected from only a single central image portion 210, and may include a plurality of central image portions 210, a first side image portion 220, a second side image portion 230, (Not shown).

(5) Description of the image projected on multiple displays according to the screen baseball system according to the embodiment of the present invention

Referring to FIG. 9, there is shown a screen 100 in which each image information is output through the above-described process.

When the source image information that has not undergone the process for distortion is outputted to the first side screen 120 and the second side screen 130, the size of the pixel SP at each point of the source image information is not adjusted, The more the image becomes distorted by the user (see Fig. 3).

On the other hand, since the size of the pixel DP at each point of the corrected image information is corrected by the proportional expression using the trigonometric function, the image projected on the multiple displays according to the embodiment of the present invention, The distortion of the image felt by the user is prevented or reduced.

In other words, as compared with the case of FIG. 3, it can be seen that as the side screens 120 and 130 move from one side adjacent to the center screen 110 to the other side, the size of the output image becomes smaller.

Therefore, the user can feel the same sense of realism as the actual baseball stadium, thereby enhancing the user's interest and immersion.

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. It can be understood that it is possible.
