How to adjust the image on a cylindrical screen device{METHOD FOR ADJUSTING IMAGE ON CYLINDRICAL SCREEN DEVICE}

The present invention relates to a method for adjusting an image in a cylindrical screen device, and more specifically, to automatically adjust an image based on the density of a user occupying the cylindrical screen device and the direction of a user entering or exiting the screen device. It's about how.

Due to the recent development of the electronics industry and the growth of related markets, electronics are used in various ways in various fields such as advertisement, marketing, exhibition, and medical fields as well as in the fields of life, work, and entertainment.

In the related art, most of the electronic devices are controlled using individual input devices such as a keyboard and a mouse, and the interface is controlled in a simple manner in which the result is output by an output device such as a monitor or speaker. Even today, in an environment where individuals control individual electronic devices, such as living spaces and work spaces, it is still effective.

However, when many people, such as subway stations, shopping malls, museums, and exhibition halls, use a single electronic device or system at the same time, it is difficult to use individual input devices such as a keyboard or mouse, and interaction efficiency decreases. Without installation, only large outputs for viewing advertisements were installed, and shoppers and visitors were forced to consume content unilaterally by viewing the installed large outputs.

Recently, thanks to the development of related technologies such as transparent electrodes and outputs, touch screens have been widely commercialized, and motion sensors have been widely commercialized with the improvement of camera performance and recognition software. Accordingly, as a method of controlling the interface of the electronic device by touching the touch screen or controlling the interface of the electronic device using a motion sensor is common, consumers through the touch screen and motion sensors installed in public places such as subway stations, shopping malls, and museums Was able to interact directly with the electronics.

However, in the case of an interface control method using a touch screen, it is effective for screens of a certain size or less, but it is difficult for a user to control all parts of the output for a large screen having a very large size. It was installed at a high position so that it was more difficult to utilize the touch screen.

The interface control method using the motion sensor can solve the problem of the touch screen, but despite the development of related technologies, the recognition rate for recognizing the user's gesture is not yet high, so it is difficult to completely control the interface with only the gesture. , There is a problem in that the recognition rate is further lowered when a large number of people simultaneously perform a gesture in a public place.

In addition, in the case of the currently widely used flat screen, a new type of interactive screen device is needed because the viewer must look at the side of the screen instead of the center of the screen and distort the image.

Republic of Korea Registered Patent Publication 10-1709310 B1 Republic of Korea Patent Publication No. 10-2008-0065782 A

Accordingly, the inventors of the present invention sought to increase the recognition rate, intuitiveness, and immersion in viewing-based interface control by providing a cylindrical screen device different from the existing flat screen device.

In such a cylindrical screen, a large number of users can view individual images from all directions, but since the size of the screen is fixed, if an individual image is assigned to all users, the more users watching, the larger the size of the image that can be viewed by individuals. Becomes smaller.

Therefore, rather than outputting individual images by the number of users, it is realistic and efficient to divide the display area of the cylindrical screen into a predetermined number and output a single image to watch together when multiple users are located in this area. .

However, if an image of a constant size is continuously output without considering the density of a user in one area, it is inevitable that a large number of users experience inconvenience.

Accordingly, the present invention automatically adjusts the size or object alignment of the image being output based on the density of the user occupying the cylindrical screen device, and furthermore, the aspect ratio of the image based on the direction of the user entering or exiting the screen device. The purpose is to automatically adjust the ratio or alignment of objects, so that there is no inconvenience even when a large number of users simultaneously watch the video.

These examples are described in detail enough to enable those skilled in the art to practice the present invention. It should be understood that the various embodiments of the invention are different, but need not be mutually exclusive. For example, the specific shapes, structures, and properties described herein can be implemented in other embodiments without departing from the spirit and scope of the invention in relation to one embodiment. In addition, it should be understood that the location or placement of individual components within each disclosed embodiment can be changed without departing from the spirit and scope of the invention. Therefore, the following detailed description is not intended to be taken in a limiting sense, and the scope of the present invention, if appropriately described, is limited only by the appended claims, along with all ranges equivalent to those claimed. In the drawings, similar reference numerals refer to the same or similar functions across various aspects.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings. First, a description will be given of an embodiment of a cylindrical screen device in a form suitable for performing a screen device image adjustment method.

Components of the cylindrical screen device

1 and 2 are a front view and a plan view respectively showing a cylindrical screen device according to an embodiment.

Referring to FIG. 1, the cylindrical screen device 1 according to an embodiment includes a cylindrical screen 10 for outputting an image projected from an omni-directional 360 degree, a support frame for supporting a lower end of the cylindrical screen 10 ( 20), a plurality of projector holders 30 arranged at regular intervals around the cylindrical screen 10, a plurality of projectors disposed on each projector holder 30 and projecting each image on the cylindrical screen 10 (40), a plurality of cameras (50) for photographing the 360 degree omnidirectional of the screen device (1), detects the user's position within a certain distance from the screen device (1), and outputs an image based on the location information It includes a control unit 60 for adjusting or adjusting as a component.

The image projector is a device that projects the output image on the front screen. Depending on how the image is displayed, the CRT (Cathode Ray Tube) projection method, the LCD (Liquid Crystal Display) projection method, the ELCOS (LCoS, There are liquid crystal on silicon (DLC) projection methods, DLP (Digital Light Processing) projection methods, and the like.

Recently, a short focus projector having a short distance between a light source and an output panel has been developed while using a laser light source capable of realizing a large screen on a large screen. In this case, the distance between the screen and the light source unit can be configured close, thereby reducing the restrictions on the installation space, and there is an advantage in that it is easy to implement a large screen that is difficult to implement with LCD or OLED.

The cylindrical screen device according to an embodiment of the present invention is designed to output an image on a cylindrical large screen screen using a single-focus projector and to simultaneously control a system by sensing a user's position, moving direction, and speed.

The cylindrical screen 10 is configured to reflect an image output from the projector 40 so that a user can watch it. In the conventional projector-screen projection system, a flat screen is mainly used, but the present invention introduces a cylindrical screen to overcome the limitations of the flat screen in a gesture or position-based control system.

In one embodiment, the cylindrical screen 10 is composed of a cylindrical frame and a screen paper made to surround the side surface of the cylindrical frame. The screen paper may be formed of a material having flexibility, such as a cloth or synthetic resin film, and may be formed of an opaque material so that light does not transmit to the back side in the opposite direction from which an image is projected.

The support frame 20 supports the lower end of the cylindrical screen 10 and is used to adjust the height of the screen. As illustrated in FIG. 1, it may be combined with a plurality of projector holders 30 through a coupling component such as a connecting arm. The projector holder 30 can arbitrarily adjust the height, direction, or distance from the cylindrical screen. For example, if the user is short, adjust the height of the projector holder 30 to a low level, or if the user is viewing the video from a distance away from the screen, the connection arm is extended to adjust the distance from the cylindrical screen to the screen. The size of the projected image can be enlarged. The support frame 20 is not fixed to the ground and may be manufactured to move the screen device including wheels.

1 and 2, at least one projector 40 is mounted on each projector holder 30, and a control signal is received by wire or wireless from the control unit 60 to image an image on one surface of the cylindrical screen 10. To project. Here, one surface of the cylindrical screen is an area corresponding to the user's location or an area corresponding to the changed location of the user, as described later.

In one embodiment, the number of projectors 40 and projector holders 30 may be determined differently depending on the diameter of the cylindrical screen 10. That is, the larger the screen is, the larger the number of projectors and projectors that can be mounted. This is because the larger the screen size, the more users the device can accommodate, so multiple projectors are required to output more screens. For example, when the diameter of the cylindrical screen is 100 to 110 cm, the projector is preferably composed of about 5 as shown in FIG. 2, but this is only an example for understanding and is not limited to a specific number.

In one embodiment, the support frame 20 may be manufactured to accommodate a plurality of cameras 50 and the control unit 60 therein. As illustrated in FIG. 1, a plurality of cameras 50 may be disposed at regular intervals around a pillar of the support frame to photograph 360 degrees in all directions. The control unit 60 may also be accommodated in the lower end of the support frame 20. However, the inner storage form of the support frame 20 and other components 50 and 60 shown in FIG. 1 is merely exemplary, and is not limited thereto, and may be changed in design in various forms.

In one embodiment, the camera 50 captures an image including depth information such as an RGB-D camera, an infrared sensor, and converts and stores all kinds of optical devices into digital signals so that the processor can process the captured image. It can contain. For example, in the case of Kinect developed by Microsoft Corporation, it is possible to obtain depth information of an image by receiving reflection of infrared rays emitted from the transmitting unit including an RGB camera, an IR transmitting unit, and an IR sensor unit. . Based on this, the control unit 60 may recognize that the user is close if the depth value is smaller than a predetermined value.

The type of the camera 50 is not limited to the above example, and all other types of optical devices capable of recognizing a person from an image, such as an eye tracker or a head tracker, may be included therein. .

The plurality of cameras 50 are arranged to photograph 360 degrees in all directions from the center of the cylindrical screen 10. As the number of cameras is more and more closely arranged, the accuracy and recognition rate of the user's position detection increases, but since it requires more cost and computation, it is acceptable to configure the minimum number of angles so that the angle of view of each camera can cover 360 degrees in all directions. . For example, if the angle of view of each camera is 90 degrees or less, at least four cameras are required to detect the user's position in all directions of 360 degrees.

The control unit 60 is used to detect a user's location based on the image captured by the camera 50 and to output or adjust an image based on the location information. The control unit 60 may correspond to a general computer (eg, laptop, desktop, etc.) including a processor such as a CPU, memory, input/output terminals, and electrical circuits constituting them. The control unit 60 may be composed of a plurality of computers, and each computer may be electrically connected to at least one projector 40 and the camera 50. However, this is only an example, and a plurality of projectors and cameras may be connected to one computer.

How to adjust the image on a cylindrical screen device

3 is a flowchart illustrating a method of adjusting an image in a cylindrical screen device according to an embodiment. Hereinafter, steps S100 to S700 will be described in detail with reference to each drawing.

According to one embodiment, first, a step (S100) of dividing the screen area and the position area of the cylindrical screen into a predetermined number is performed.

The screen area is an arbitrary screen portion in which an image is projected by a projector in a cylindrical screen device, and each of the plurality of projectors is set to project an image on a corresponding screen area. The location area is a user's randomly divided area located around the cylindrical screen device and corresponds to each screen area.

For example, referring to FIG. 4, the screen device is divided into five screen areas and a position area (in this case, each area is equally allocated by 72 degrees), and the screen area A corresponds to the position area A'. And the screen area B corresponds to the position area B'.

The reason for dividing the screen area and the position area as described above is, when two users are located in the same area based on the divided area, one image is adjusted and output, and when two users are located in different areas, two images are output respectively. This is to provide a convenient viewing environment for multiple users.

Referring to FIG. 3 again, detecting the position of the first user within a certain distance from the cylindrical screen (S200) and outputting the first image to the screen area corresponding to the detected first user's position (S300). ) Is performed.

Step S200 is performed by a plurality of cameras capable of photographing a 360 degree omnidirectional view of the cylindrical screen device as described above, and a control unit capable of detecting a user's location based on depth information of the photographed image. For example, Kinect, developed by Microsoft Corporation, receives the infrared rays transmitted from the infrared (IR) transmitter and reflects them to acquire the depth information of the image in real time, and the depth value is smaller than a predetermined value. It can be recognized that the ground user is approaching around the cylindrical screen.

For example, it is assumed that the cylindrical screen device has 5 screen areas and a position area as shown in FIGS. 4A and 4B. When it is determined that the first user exists in the location area A'as a result of shooting with the camera, the control unit controls the projector corresponding to the location area A'and outputs an image to the screen area A. This image, which is output for the first accessed user, is referred to as a first image to distinguish it from an image that is output for another user who is subsequently accessed.

During the output of the first image, if the second user comes within a certain distance from the cylindrical screen, a step of detecting the location of the second user is performed (S400). Step S400 is performed by the camera and the control unit as in the case of the first user.

Subsequently, a step of determining whether the first user and the second user exist in the same location area is performed (S500).

For example, assuming that the cylindrical screen device has 5 screen areas and a position area as shown in FIGS. 4A and 4B, each screen area and the position area are divided into 72 degrees. The first user is in the location area A'and is watching the first image output to the screen area A. At this time, as a result of detecting the position of the newly introduced second user, if it exists in the location area B'as shown in FIG. 4A, it is in a different location area, and if it exists in the location area A'as shown in FIG. 4B, the same position It is judged to be in the realm.

Accordingly, when two users exist in different location areas (FIG. 4A), a second image is output to a screen area corresponding to the location of the second user, and when the two users exist in the same location area (FIG. 4B) ) The adjusted first image is output to the same screen area (S600).

5A and 5B are diagrams illustrating outputting a second image to a screen area corresponding to a location of a second user when two users exist in different location areas. The second image may be the same image as the first image or a completely different image. As such, if the user approaches a different location area, the screen device allows multiple users to watch individual images in all directions.

6 illustrates that when the two users exist in the same location area, the first adjustment image obtained by adjusting the first image is output to the same screen area. As shown in a, if the first user is alone in the location area, the first image is output to the corresponding screen area. Thereafter, if the second user is detected in the same location area as the first user, the control unit outputs a first adjusted image in which the size and object alignment of the first image are adjusted as shown in b, to the same screen area.

The first adjusted image is an image in which the horizontal size of the first image is enlarged at a predetermined ratio, and objects in the image are newly arranged according to the changed aspect ratio. This is to solve this problem because it is inconvenient to view or control a small screen when an image of the same size is output when one or more users watch one image.

In one embodiment, the horizontal size enlarged in the first adjustment image may be set differently according to the direction in which the second user flows. To this end, the image adjustment method of the present invention divides the position area into three equal parts into a left area, a right area, and a front area (S610), and which area of the left area, right area, or front area is located by the second user The detecting step (S620) may be further included.

This is not to simply enlarge the image at the same rate when there are more users watching one image, but to adaptively take into account the approach direction of the newly introduced second user so that users can watch more comfortably. to be.

For example, if the screen area and the position area are divided into 5 as shown in FIG. 4B, one area has a range of 72 degrees, and the left area, the right area, and the front area divided into three equal parts have a range of 24 degrees, respectively. The position of the second user captured by the camera is detected, and it is determined from which direction from the same position area A'. If the second user approaches from the left side of the first user as shown in FIG. 4B, the control unit determines that the second user is located in the left region and determines the ratio of the horizontal size to be enlarged and the object alignment method accordingly.

In one embodiment, if the second user is located in the left area (that is, if the second user approaches from the left), the horizontal size of the first image is enlarged by a ratio of 3:1 left/right as shown in FIG. 7A. Then, the objects in the image are rearranged according to the determined aspect ratio to create a first adjustment image.

The object in the image refers to the displayed content. For example, it means various types of content displayed on a computer, such as an image playlist, a preview icon, and an interface icon. In one embodiment, the object array of the first image is a matrix (3X2 array) in which a row is larger than a column, and in the second adjustment image, the object array is a row whose column is larger than a column. Changed to a large matrix (2X3 arrangement), while moving to the left or right, it can be implemented in a form that the spacing between objects is widened.

In one embodiment, if the second user is located in the right area (that is, if the second user approaches from the right), the horizontal size of the first image is enlarged by a ratio of left/right 1:3 as shown in FIG. 7B. Then, the objects in the image are rearranged according to the determined aspect ratio to create a first adjustment image.

In one embodiment, if the second user is located in the front area (ie, if the second user approaches from behind the first user), the horizontal size of the first image is equal to the left/right ratio as shown in FIG. 7C. Magnify and rearrange the objects in the image according to the determined aspect ratio to make a first adjustment image. When the second user is located immediately after the first user, the object arrangement changes from 3X2 to 2X3, but does not move to the left or right.

Referring back to FIG. 3, when a first user or a second user deviates from a certain distance from a cylindrical screen while outputting the first adjustment image, outputting a second adjustment image that has been re-adjusted the first adjustment image. Is performed (S700).

When the density of a user in one screen area or location area decreases, it is no longer necessary to maintain a wide screen, so the horizontal size of the image is reduced again and the arrangement of objects is rearranged according to the reduced number of users. That is, the second adjustment image is an image in which the first adjustment image is reduced again and the objects are rearranged according to the reduced aspect ratio.

Even in this case, as in the case of adjusting the first image to make the first adjustment image, the direction in which the user flows out is classified as left/right/front to adjust the reduction ratio of the horizontal size accordingly. For example, if the first user or the second user is located in the left area and is away from the screen device, the horizontal size of the first adjustment image is reduced to a ratio of 3:1 left/right, and the user is located in the right area. While moving away from the screen device, the horizontal size of the first adjustment image is reduced to a ratio of left/right 1:3 to create a second adjustment image. When the user overlaps the front area and one person is leaked, the left/right is reduced to a ratio of 1:1 as shown in FIG. 7D. The alignment method of the objects in the image also changes the 2X3 arrangement of the first adjustment image to 3X2 in the second adjustment image, the interval between objects decreases, and moves left and right according to the direction in which the user exits.

The image adjustment method of the cylindrical screen according to the embodiments can be implemented as an application or in the form of program instructions that can be executed through various computer components, and the program can be recorded on a computer-readable recording medium. . The computer-readable recording medium may include program instructions, data files, data structures, or the like alone or in combination. The program instructions recorded on the computer-readable recording medium are specially designed and configured for the present invention, and may be known and usable by those skilled in the computer software field.

Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical recording media such as CD-ROMs, DVDs, and magneto-optical media such as floptical disks. media), and hardware devices specifically configured to store and execute program instructions such as ROM, RAM, flash memory, and the like. Examples of program instructions include not only machine language codes produced by a compiler, but also high-level language codes that can be executed by a computer using an interpreter or the like. The hardware device can be configured to operate as one or more software modules to perform processing according to the present invention.

According to the above-described embodiments, the size or object alignment of the image being output is automatically adjusted based on the density of the user occupying the cylindrical screen device, and further, based on the direction of the user entering or exiting the screen device. By automatically adjusting the aspect ratio of the image or the alignment of the objects, multiple users can conveniently view the image without limiting the viewing angle.

The present invention described above has been described with reference to the embodiments shown in the drawings, but this is merely exemplary, and those skilled in the art will understand that various modifications and modifications of the embodiments are possible therefrom. However, it should be considered that such modifications are within the technical protection scope of the present invention.
